Revisiting lace repeats and charting

WORK IN PROGRESS

Lace knitting for many introduces knitting with 2 carriages for the first time. The lace carriage advances the cards, mylars, or programmed pixels a design row with each pass. In other stitch types the knit carriage, once it is set to select needles ie using the change knob on KC, in punchcard machines,

or KCI for end needle selection, KCII for no end needle selection in electronic models, also advances the pattern a row with each pass. The advances happen in Brother machines when any carriage locks onto the belt and moves past the center 0 marking as it travels from one side of the stitches in work and past them to the other.
Electronic and punchcard published lace patterns may be used in both machines as long as when punchcard models are in use, the pattern repeat is a maximum of 24 stitches wide or a factor of 24, such as 2, 4, 6, 8, or 12 stitches in width for each complete repeat segment. This exchange is possible because the knit carriage does not advance the pattern repeat in both models, it is left set for and performing plain knitting, with the change knob set to N-L.
When the knit carriage(s) is (are) also set to produce patterning, extra caution needs to be taken with the alternate carriage being off the needle bed so both carriages do not lock onto the belt, which will then be anchored on one side, and pulled toward that spot from the opposite side, possibly causing it to break. One instance in transfer lace knitting when the knit carriage also selects needles is in knitting automated edgings.
Many other stitch types may be knit with 2 knit carriages selecting needles from opposite sides. It is one way to have frequent color changes without using a color changer, tensions and cam button settings can also be different. On an electronic machine, each pass of each carriage advances the design by one row. Here patterns stop being interchangeable. With 2 carriages selecting needles, when a punchcard machine is used, as the alternate carriage makes its first pass from the opposite side, the card does not advance, so the previous preselection is repeated. To use a published repeat for either machine on the other, the repeat needs to be adjusted.
If one of the two knit carriages is left set to N-L, it will not advance the pattern, adding an easy to add plain knit rows between patterned ones without having to alter cam button settings or the programmed repeat.

In transfer lace knitting, there are many considerations when attempting to represent carriage movements for both carriages in a single chart when the knit carriage is not also selecting in pattern, but simply knitting and not advancing the repeat. The first illustrations use the machine knit repeat developed from a hand knit pattern inspiration many a year ago 2013/12/05/lace-mesh-motif-charting_-mac-numbers.
Since then software versions, computers, operating systems, and my use of them have evolved and changed. I have edited the post with additional information, inked in a different color.
Experimenting with DAK has brought me back to thinking about the issues in charting lace fabrics in particular.

Two of the posts on using Studio repeats on Brother brands:
2019/02/23/revisiting-use-of-lace-patterns-studio-vs-brother-machines/
A Studio lace card with single blank rows between transfer segments knit on a 910
No symbols are used in this chart, it is intended for use on Brother machines. The red cells represent transfers to the left with LC operating from the left, the green cells represent transfers to the right, grey cells indicate knit stitch rows.
The knit rows in most lace unless the pattern is combining KC needle selection for slip, tuck, FI, or weaving do not advance the pattern rows.
LC actions are marked on the left, the KC ones on the right
The LC makes 4 passes:
1: preselects for transfers to the left as it moves to the right
2: transfers to the left as it returns to the left,
3: transfers to the right as it moves to the right, there is no preselection for the next row
4: moves back to the left with no transfers or preselection
The KC follows with 2 knit rows. In the chart for this pattern, representing only the repeat, there is no room to indicate KC passes on the left-hand column
The appearance of the chart or template changes if 2 empty rows are added to represent the KC passes. It may help one understand what is happening but in Brother machines, 2 of the 4 blank rows here would need to be eliminated for the pattern to knit properly.
Transfer design segments may vary considerably in the number of lace passes and transfers between knit rows. In the pattern below, only 2 rows of knitting are completed after 20 carriage passes, the bottom half is repeated X times, the top half X times, adding even more complexity. Depending on the knitting machine model, the pattern may also need to be mirrored to knit accurately. Published punchcard books offer patterns with potential errors usually sorted out. Both punchcard machines and electronics scan the card or mylar inside the machines, several rows down below what is visible to the knitter at eye level on the exterior of the card or mylar slots, so markings on both need to be made accordingly. This is a fact that needs to be considered with cable downloads of the same patterns if entering memos for knit rows. In the case of punchcards, Brother reads 7 rows down, Studio 5. In fabrics other than lace adjusting for the brand is straightforward ie to knit fair isle, tuck or slip pattern if using a Studio company supplied punchcard repeat, simply start the Studio card on row 3. If punching your own, design rows match, if the blank card is marked for Brother, the numbering is accurate by default. Brother cards begin with pattern selection, Studio brand with 2 knit rows. In this repeat, a mesh repeat is created first moving to the left, then to the right, the 2 knit rows follow 2 LC passes for transfers to the left, 4 LC passes for transfers to the right. Brother row one marking is underlined with a blue line, Studio with red A Studio repeat adjusted for use on Brother also illustrates that the number of knit rows are only two, the LC passes can vary in number between knit rows. Here LC passes are marked with outlines around pertinent row numbers on the right   Brother vs Studio: extra knit rows in Brother are not physically left as blank rows in cards, the rows for KC are still 2 blank ones, while in Studio cards there is a blank row for each knit row in the pattern. Both these samples have a 6 knit row sequence. Because Studio begins with 2 blank rows, in the repeat on the right only 4 rows are left blank at the top of the repeat. Adjusting for extra knit rows, Studio to Brother These samples are from Brother punchcard volume 4:
single blank rows between transfer segments varying numbers of blank rows between repeat segments multiple rows of knitting (8) marked aside a single pair of blank rows Some electronic examples using the 2-row spacing between transfer segments: this is a page directly from the Stitchworld electronic pattern book a pattern published on a full Brother mylar sheet this is from a studio mylar, the same holds true in terms of the number of empty rows between transfers, that is the reason why most transfer lace patterns unless they are designed as studio simple lace where transfers are made with each carriage pass, patterns may be exchanged between both brands, the only difference being studio starts with 2 blank rows, ends with transfer markings, Brother starts with transfer markings, ends with 2 blank rows.
Electronic repeats are interchangeable after taking that into account, but not mylar sheets in respective brand mylar readers because the number of rows below eye level where the electronic readers scan the design is also different between the two brands. 

Transfer lace may also be combined with other stitch types, each with its own considerations as in these instances both types of machines have the KC selecting needles as well. The punchcard published patterns need to be adjusted for use on electronic models. As already mentioned, punchcards do not advance with the first pass of the alternate carriage from the opposite side, while electronic models advance a row with each pass of both carriages:
adding KC slip stitch selection for creating ruffles and doilies
tuck stitch
weaving 1, weaving 2
fair isle

The lace module in Dak will do the work for the knitter once the pattern is entered as symbols. Eyelets will be represented in single rows, a shorthand version of the previous samples. Reviewing how the transfers would appear on the knit and the purl side respectively. The LC can move only one needle at a time, so when multiple needles need to move to place the eyelets properly, the options are to use a hand tool performing the moves or to develop a pattern with multiple transfers in each segment of the final repeat. The full repeats are often very long.

I am a complete novice at the use of this program, tend to start learning new tools by comparing them with what I am familiar with, which in my case are spreadsheets and other paint programs. I have decades of playing with changing file formats depending on end-use. My questions on aspects of the program’s use are not intended as criticism, they are born of curiosity and the attempt to explore a new tool.
I am using Dak on a PC, at the moment my blog posts are created exclusively on my Mac. There is much that is fluid in addition to learning the software.

These are the formats that can be opened as stitch patterns, converted to stitch patterns using Graphics Studio Stitch Designer, or opened as a background image in Original Pattern Drafting and used for tracing a garment piece: BMP, GIF, ICO, JPG, PCX, PNG, TGA, TIF, WMF, P?M. There is no export option for saving the repeat images in stitch design file formats for use in other than the native program. Passap CUT files are completely excluded.
I lean towards looking for workarounds to accomplish what I want if the task is not native to the program I am using.
One way to achieve conversion for DAK file formats for use as a png or bmp download with other cables and software:
isolate and select the repeat unit, copy it to clipboard, paste in a paint program, export as png or other desired formats There is a handy option in Dak when thumbnails is chosen from the image menu, one can browse through saved folders containing compatible file-formats including the images in those Brother magazine downloads. The small preview will identify the specific file size. When you left-click on your choice, it will appear enlarged at the bottom left of the view window, it has been moved from its corner in my screengrab, left-click OK on the enlarged image, it will open in the program window. Minimize the size until no further reduction is allowed by using the magnifying glass or the scroll function in the mouse. This is a different operation from scaling the original to a different size. The save-as option for the image offered at that point are:
For choices emulating export in other paint programs, right-click on the image, choose copy, open a paint program (Arahpaint is my favorite at this moment), and from its image it menu choose paste. Using Arah’s color exchange, the image may then be converted to black and white for 2-color work and is saved in a format usable with other software and in other machines. Here the image has been pasted in Gimp using the same process, but if the image needs to then be reduced to BW, Arah is the easier and predictable tool to use.
Activating the working palette, referred to as yarn colors: from the manual It is possible to achieve color exchange easily in Dak as well. Most operations appear to rely on an understanding of its symbols and what might be considered a language one must learn in order to use the program effectively. By activating the view yarn button palette, the items that may be viewed and changed are:
A: represents left mouse click on that color
B: represents a right mouse click on that color
C: click will swap A color to B color
D: needle hook alone represents non selected needle, pusher, or simply color depending on the machine model
E: color worked on patterning needle ie contrast in fair isle, knit stitches in tuck or slip setting It is useful to establish working history using the same design motif. In the first image, left-click on red, the from color, right-click on white, the to color, click on the double arrow to make and apply the change
The process is repeated with left-click on blue, right-click on black, and on double arrow. White squares appear in the final color choice boxes in the bottom image
The print dialogue allows for saving patterns as bmps. One is walked through the following steps with a series of windows. To save the repeat as bmp
from the manual choices may then be made about file name and the location for the save, If there are no “short” needles in the image being processed as in the last screengrab above, there will be an error message onscreen, pointing out problems in the numbers of colors present in rows ie more than 2 for FI.  This is fixed by clicking on either the “needles” of one of the two active colors in the yarn palette to make one color the ground, the other the contrast. The results from this process for printable bmp files are shown below, not for a bmp that may be used to knit the pattern on an electronic machine using a different download method. Here the resulting stitch pattern picture is shown in color reverse as well.  Using other print options: for this repeat, the color change page is blank since the fabric is being knit as a 2-color fair isle, without added color changes  Printing pattern text will do exactly that in longhand form, for each stitch and each row of the repeat 

Dak is the only program I know of for home use that allows for visualization of the knit design with approximations of knit stitches, seen here in both the BW and the original color version of the above FI design, shown as knit stitches on the public side. The image needs to be a minimum size for the appearance of the details as is true in most paint programs for grid views.   At this time I am continuing to knit on my machines with punchcards and using Ayab, or img2track on my electronics, have no immediate plans to change that, hence my interest in using DAK software features while keeping in mind the possibility of using the final repeats on other machine models.
Working with lace designs: lace poses interesting challenges in machine knitting. The name is associated with a variety of fabrics, but transfer lace is the specific topic for the moment. It appears much of the information that can be found online is specific to Studio machines, for which Softbyte provides their one true knit from screen cable units. The company website tutorials for  Version 9 do not include a video on the lace module at this time.
Reminders with respect to lace knitting:
in studio simple lace the transfers and knitting occur for each row of the design  with each pass of the carriage
transfer lace patterns in Studio km begin with 2 blank rows, end with needle markings for transfers
Brother transfer lace begins with needle selections for transfers, end with two blank rows
hand knitting charts typically illustrate the knit side, while in machine knitting one is working looking at the purl side, so usually if charting for duplicating the same transfers, the HK pattern requires mirroring
Brother lace carriages select from the left, Toyota from the right
some download programs automatically flip patterns horizontally, great if you are working with texts in most cases, but a consideration if you wish to control the direction of other stitch type formations, and lace patterns may need to be flipped as well in order to knit properly on Brother with the lace carriage operating from the left side.
To knit successfully in DAK, there must be no errors, an even number of total rows, drawing occurs on every other grid row, with odd row starts for the lace carriage to operate from the left.
Out of habit, I try if possible to work with repeats suitable for punchcard machines as well.
Facebook members who participate in machine knitting forums have access to the information generously shared by members. Sheila West published a video on drawing lace repeats on a DAK knit stitch symbols ground as opposed to the more traditional charting using lace symbols on a blank design grid, and there is also an associated downloadable PDF.
Presently there are no directions for using the lace module, which has been available for years and previous DAK versions, either on the Softbyte website or in the DAK 9 manual.
The lace tool is an extremely attractive possible solution for speeding up the lace design process whether from published charts or DIY. Stitch symbols are used, this is the range of available, To select the lace mode however, simply click on the small icon on the left, a grey border on its left and the upper edge will indicate it is active I find it best to begin testing with a small repeat when exploring new techniques, find his format easier to use than drawing on “stitches”. There are several options for the canvas ground color, the default is in blue. As a first step, saved as an stp, Dak opened my saved file as pictured in this view.  The pencil tool must be active to continue to draw, left mouse click to place symbol, right mouse click to erase, clicking on any symbol in any one row will call up pertinent information on its location in the repeat DAK row numbers do not refer to design rows, they reference row counts as would be seen in any row counter registering carriage passes
Other views for the repeat: as yarn colors and as stitch symbol palette If a symbol is missing from the drawing, the program alerts the knitter to the error.  Here there are no eyelets represented.   If the content is considered accurate, this window will appear, the safe button will be highlighted, click OK When choosing machine knitting options lace is not offered as one If one wishes to print a template for use on another machine the stp file may not be used for copying to clipboard and converting to stitches in another program. In the print menu, saves are possible for use as templates akin to graph paper references for working further on both electronic and punchcard machines. For the electronic printout, the choice of the machine appears to need to be set to 950i wrong side facing is chosen for the purl side view.  Stitch pattern print previews, using default settings for layout:
the stitch pattern picture is basically a numbered graph paper image with no content, pattern text was not particularly useful
other previews
the supposed electronic repeat for punchcard end-use, change the machine to Brother/Knitking standard punchcard, click ok. When you choose Fair Isle, DAK will reverse your design and that may mean that there will be two eyelets side by side or double stitches transferring because the transfers are being made in the wrong direction.  Whether the pattern actually needs mirroring again to be accurate depends on your download program ie Ayab mirrors the programmed image automatically, or your specific brand machine ie punchcard vs. electronics may behave differently. An easy test is to use the repeat on a small swatch, if side by side empty needles appear on the needle bed, the pattern needs to be reversed. the repeat:
Numbers on the left,  correspond to carriage passes, not design rows. While the electronic printout differentiates between rows for use of the LC and KC, leaving the KC rows unlabeled, that distinction is not made here.
Assuming the knitter knows whether the programmed repeat will need to be mirrored or not to knit properly on their specific model knitting machine, the 24 stitch punchcard version should work on both as given.
Here lies the problem, at least in this instance: there are 2 errors in the Dak printouts, the three blank rows rather than 2 in the outlined section between transfers, and transfers in 2 different directions occurring on the same row with the same carriage pass. I have no way to test whether the same issue would occur in interactive knitting using my own stp file. My repeat, drawn in Numbers on the right, is numbered in design rows. When choosing print, the global options allow for editing items out such as company name, date, format by simply clicking in the associated boxes choices can also be made on how to represent stitch units If the plan is to create a punchcard template and the repeat is too large, an error message appears The proof of concept swatch, knit on a Brother 930 KM, mirroring the image was not necessary, the dropped stitch was a surprise design feature when the swatch was very lightly pressed its.png Regrouping after a review of my repeat from Softbyte support: the original stp has an error in it on row 11 where yours truly had eyelets being created by having the same stitches moved in opposite directions in the same row. It is interesting that I was able to save the stp without receiving an error message as seen in this instance below when the pattern was being redrawn with transfer symbols on the wrong row, The amended final repeat in turn produced a correct punchcard template using the print preview in DAK. As an additional lace template test, I tried the same process on a portion of an stp file shared generously shared by a DAK FB group knitter along with photos of a completed, lovely lace sweater using it.  The results are shown sideways because of the repeat length. The 950i template places four rows at the end of each lace sequence, while as seen in the published repeat of a different lace beside it, there should only be 2. The carriage passes made by the KC in lace knitting though they advance the row counter, do not advance the pattern unless it is selecting needles as well, ie in trims that combine lace with the slip stitch setting. Exceptions to the 2 blank rows rule occur when the lace shape reverses direction such as in zig-zags, or when plain knit or pattern rows are planned deliberately to mix and interact with the lace design. Please see the next post for more on lace charting and some possible explanations for those in between rows variations.

This is another lace pattern build using the module. The diagram was offered along with a punchcard design. There is an intentional extra row at the bottom of the repeat, making it “wrong” if the intended use is on a Brother machine as a test for how the template might handle it in the print preview. Template previews were created using the setting for Brother standard punchcard bulky or Brother 950iFacilitating correct DIY designs, in addition to the warnings if there are missing symbols or any other problems with the design and their respective row locations, the module provides a warning about that extra row, explaining that if the generated pattern is used as is, the bottom row should be moved up or the LC should begin pattern selection from the right. The electronic preview continued to have a series of 4 blank rows between transfer segments. My repeat received no warning as to problem rows or symbols, saved as an stp, the associated print preview had issues again. Published patterns may also not always be correct: the renderings below begin with the DAK punchcard template on the left with confused numbering, the extra empty row at the bottom of the repeat eliminated, and another 3 blank rows occur at the top of the sequence. It is followed by the published pattern associated with the repeat, pixels are then marked for left and right transfers, followed by my amended repeat, which when knit on the 930 required mirroring. The convention for lace designs is that they contain an even number of rows, the one on the right is 47 rows, knits properly, is suitable only for a border. Here I knit a couple of extra rows and reprogrammed row 1Letting the repeat knit as a continuous pattern with a total odd number row count reverses the direction of the transfers, resulting in mispatterning and multiple side-by-side empty needles in the subsequent full repeat. Changing the total repeat to 48 rows places transfers overall in matching directions. The small flower shape could be moved up and its transfers reversed,  but in this instance the 48-row version, though transfers were made in the correct direction,  still did not produce the continuous pattern alignment I would prefer. The challenges in DIY lace patterning are many.

My DAK journey start

I have avoided personal shares here, keeping to technical topics. This will be an exception, providing some of my knitting history highlights.
Over the years I have had extensive experience using other programs and shared my explorations here as I sought to develop ways of using them to develop patterns for use in punchcard models and on electronic machines, whether with mylars or download cables.
The charts for my blog and stitch patterns grew to use a combination of specialty fonts, native OS apps such as Numbers and Pages as I became primarily a Mac user, and a variety of paint programs including free ones such as Gimp and ArahPaint. Some programs such as Cochenille StitchPainter and Intwined were abandoned over for a variety of reasons.
I have written about converting lace hand knitting charts for use on electronic machines,  published my own designs and conversions from a variety of sources to pixels exported in end-use formats.
From my early teaching and garment-making days, I preferred using a knit leader for complex shapes and the magic formula and some basic math for drafting patterns, resisting knit calculators, and drafting programs that relied on default curves.
My first exposure to DAK was at knitting machine seminar marketplaces, in the local ones, DAK reps were in one corner, and Cochenille in the opposite, pitching their early ideas for knit design.
I opted for Cochenille, Stitch Painter, and eventually used their download cables and Amiga/Commodore for my personal designs.
My first machine was a Studio metal bed bulky with no patterning capacity, purchased after viewing one in another state while my friend took too much time shopping for shoes. My second machine followed a few months later, a Studio 560, and my first production knitting was a series of 53 custom caps, each with different FI designs, developed for friends and coworkers of my husband at the time which “justified” the purchase of a second machine.
At the time, there were no major craft venues locally, I met a group of women who were attempting to find a way to sell their fiber work. My first knits for sale were part of a line of children’s knitwear. Many of my friends went on developing businesses that included knitting weaving and felting.
At some point, with my son enrolling in design school at RISD, applied to and became enrolled in the fibers department at Mass Art, presenting a portfolio that included mostly some of my knits.
At the time the fibers department owned a 910, but no one had experience using it. I used every opportunity I had to experiment with it, even at one point producing a piece for an English Literature class, purchased a 910 so I could work at home outside studio hours as well. My commutes to the school were using the local subway system, often lasting more than an hour each way.
The department chair at the time trusted that I was expanding my learning as I went, actually purchased many of my final pieces.
Because I had a previous degree (in nursing) and accompanying credits as well as attending classes year-round, I was able to free up time during the fall and spring semesters and to include some computer classes. During my three years as a full-time student, the computer lab transitioned from an all Amiga one to introducing and then eventually switching to all Apple Mac.
Early scanning for conversion to knittable patterns was achieved with home BW security cameras and RGB filters.
Machine knitting at the time was at its height, there were international seminars attended by teachers and knitters who traveled worldwide, sometimes they were brand-specific like Passap University. The opportunities for learning, keeping up with advances in translations from other language manuals, magazine publications from Japan abounding before other countries tried to play catch up, and self-published pattern fliers and books were easily available in the accompanying marketplaces, awesome learning tools in a pre-internet or even pre-web tv and prior to the first online forums like those found in Yahoo groups.
As many knitters do, my machine inventory grew, and I acquired a Passap as well. The first downloads to that were directly from the computer, with a short dongle, and from the start, the files were created in wincrea in the proprietary CUT format, with a library of patterns provided by Madag. Eventually, the dongle was replaced by me with Cochenille download cable enabling knit-from-screen on an E6000 with an 8K console, followed many a year later by a 32k console model.
Three weeks before completing my degree at Mass Art I interviewed at RISD, bringing with me some of my knits in a portfolio case borrowed from my computer teacher, based on the pieces including one knit on the Passap I was hired immediately, changing both my life and knitting direction for the decades that followed.
As I began to teach, with an early PC available in my knit Studio, I had my first exposure to Windows versions of the Cochenille software.
The knit studio was an all Brother lab at the time, the majority of the machines were punchcard models, with as I recall, 4 electronic machines, a couple of 260s, and at least one Studio metal bed bulky with no patterning ability. That led to my first purchase of a Brother punchcard model. Up to the development of final projects, only punchcard models were used in the knit lab. Ribber fabrics were reserved for the advanced knitting curriculum unless again, ribber bands were required in a final project.
As the Cochenille interface was abandoned and Commodore faded from the market, the present version of wincrea was developed by the husband of a knitter in Australia and became available as a download to the general public for use in PCs. I continued to work on my Passap, using the program and the Croucher download cable and switch box, purchased from England on a few PC versions over the years.
I chose to leave my teaching job after 13 years because of a shift in the school attitude toward students and what should be fair educational expectations as efforts were made to double the overall enrollment, along with other choices based on space efficiency, double daily studio use, by folks who had never seen or heard a machine in use or had a clue about the process involved.
I began to produce knits for sale at shows and in galleries as a source of income.
I missed teaching, have always been drawn to the puzzle-solving involved in developing different types of knit structures, online communities grew, and my blog which began as a way to share what I was making slowly evolved into what it is today.

I am presently awaiting the delivery of a new iMac with an M1 chip. It is not known to me at this point, whether Ayab or img2track will continue to be compatible or usable.
In the past couple of years, most of my knitting has been creating swatches using img2track on a 930, when the time to knit was limited and immediate satisfaction and reliability were a real plus. My Passap has been in deep sleep other than for rare swatches and a couple of scarves requiring splitting the design length. I was never able to get the USB-to-serial connection to work properly using VM ware, making my present downloads using the old cable and switch box on an ancient laptop using Windows XP.
My first hardware decision was to purchase a PC that could become a tool dedicated to knitting and related apps. The Windows setup was done for me by my son, it is not something for which I would have the bandwidth.
With a new PC in the works, I reviewed my “never, don’t need it or want it” policy in terms of DAK. It began with some misconceptions: seeing that cables were available for use on both the 8k and 32k models, and with my previous early knit from screen experience I thought the combination of cables and software would allow for bypassing the download into console memory completely, which as it turns out is not possible. That is also how the Silverlink 5 works, but it’s only for the Silver Reed electronic machines. The shared-use cable  https://softbyte.co.uk/cablelinksscreenlink.htm would appear to be an electronic row counter that advances the pattern being knit visually row by row, allowing for memos, etc., and technically usable on any model KM including punchcard machines. I also imagined that if the software would allow for the import of my personal design cut file library from my decades of knitting, which can be achieved, one at a time, with non Madag cut files using Graphic converter on the Mac. The Dak graphics studio appears to offer options for quickly and easily performing tasks I have achieved in other ways including color separations and converting stitch charts and punchcards, I purchased the program as well, intending to explore only it to start with, apart from any cable purchase, as I have other programs.

Softbyte support responded quickly and informatively to my early questions. The site lists international distributors, the US one is knitcraft, but there are also local dealers found only through word of mouth. Because of recommendations received from other users and the easy access to support and information provided by Michael Decker at Distinctive Knits, I made my purchase, the PC has arrived, the program is installed, and my journey with Dak began.

I am looking forward to exchanges with experienced users and other online information to exploring possibilities and differences from other tools. Will share as I go.

 

 

 

 

 

ArahPaint meets Gimp in knit design

WORK IN PROGRESS

Questions regularly turn up asking what software we use as individuals to design repeats for our knitting. Up to this point, I have worked exclusively on a Mac unless downloading to my Passap with Wincrea, an ancient laptop, and as old a version of windows.
I have been a Gimp user for eons, it is my go-to along with Numbers to create the charts in my blog and to graph my designs and ready them for download.
ArahPaint is a free paint program, part of a far larger weaving one. I have used it intermittently for features not achievable in Gimp at all, especially prior to its latest Mac updates. My Gimp working notes may be found in blog posts including the latest 2021/07/18/gimp-update-for-mac-2/.
The scope of AhrahPaint is smaller than that of a full photo editor, but its functions are well worth exploring from simple designs for use in any craft including hand knitting, cross-stitch, etc for scaling images to size, drawing in repeat, configuring those repeats in many arrangements easily, for color reductions, and much more for end-use in machine knitting.
There is a very good downloadable manual, but not generous in providing small details applicable when working in a low res bitmap such as that found in knit design.
My goal here is to provide some starting ideas on using the program for new users and a few comparisons to Gimp features for those who have worked with that program in the past.
Links for anyone wishing to try Arahpaint on a Mac (or Windows), including video tutorials
Sept 20, 2021: a new version of the software is now available for download, it is larger in file size https://www.arahne.si/learn-support/software-demo/
A “fast pattern” supplement http://www.arahne.eu/pdf/fastpattern-EN.pdf, black and white images are used on pages 20-24,
The user manual appears unchanged
The drawing in repeat window now offers new Preview, and Browse options. If Paint is part of the complete weaving program, there is a library of patterns for the user to browse through. If it is used as a stand-alone, the choice provides the opportunity for the user to browse through their personal library of images before continuing.  The information available to me as I began this post:

Arah menu options provide a quick view of menu differences between it and Gimp Tools as listed in the shortcuts pdf, the order is slightly different than in the program view When exploring design potential in any paint program, it is best, to begin with, to use a small repeat that can be clearly identified when tiled in various configurations, resized, and pixel edited. If drawing is with the goal to produce a BW bitmapped image for download of 2-color patterns, drawings can happen in those colors to start with. If color separations are planned in the development of the design, then 2 color images including black may be preferable.
The Arah default dot size for pixel drawing is 1X1. The 8-bit palette mode both for colors and greyscale uses up to 256 shades, greyscale values may also be measured in percentages of black ink coverage. Images may be converted from one color mode to another as in Gimp.
Begin with a small image size To work on the image, magnification will be required. This may be achieved in two ways on the Mac, one is to click repeatedly on the magnifying lens icon in the toolbox, the other is to press any number from 0 to 9 on the keyboard, the zoom will instantly change for 1 at 100%, to 6 for 600%, to 0 for 1000. The latter is minimal for building repeats on a viewable grid, the magnifying lens may be used to reach a comfortable starting view. The zoom level for both increases and decreases may be changed during drawing operations as well.
In addition, the image may be also be magnified to fill the window, and the program may be used in full-screen mode on your device by making the very last selection in the View menu. At zoom levels higher than 300%, the program shows a grid between pixels, if the grid view is enabled.
To show or hide the grid, choose View, Show Grid
To change the grid properties, choose View, Grid properties
The grid color can be black, gray, or white.
The second level grid determines every how many thin lines a thicker one will be drawn
Setting the grid: the default grid is subdivided, grid color and spacing may be custom set through selections in the View menu Altering the thicker line placement to suit personal preferences or to match electronic or punchcard published repeats more easily, simply type in new values and close Punchcard knitters may use this feature to create a template on which draw. Factory supplied Brother punchcards are by default 24 stitches wide, the maximum repeat width, and 60 rows high with the minimum design height of 36 rows for the card to advance continuously in the card reader.  The grid spacing is 6X6. With values changed to 6, the template is created The default cell shape appears to be square, without the option to create rectangular cells. Changing the grid option to lose subdivisions: deselect show grid 2. In addition to the image grid, like Gimp, ArahPaint 6 also allows for positioning aids: guides. They are horizontal or vertical lines that are temporarily displayed on an image. To create a guide, double click on the dark blue arrow displayed on one of the rulers in the main window. The guide is then displayed as a dashed line, which follows the pointer. To move a guide after it has been created, hover a mouse pointer over the blue arrow and click and drag it to remove the guide to a new location. To delete a guide, double-click on the arrow. After a guide is created, another triangle in a different shade of blue appears below it. Use that to create the next guide, repeat as often as wanted both horizontally and vertically. To remove all guides choose View, Remove Guides. One use for the lines can be to mark plain knit rows between transfer markings in lace punchcards as illustrated in this Gimp image

To test the program, draw a basic shape whose changes may be easily recognized. Color palette tools are in the palette areas. Foreground (upper square) and background color (lower square) are used in drawing operations. They are numbered 1 and 0, not to be confused with the same numbers assigned to colors in the working palette. The starting palette may be altered to include black. Double click on the foreground color at the top, the #1, not in the space below the palette icon. A color selection window will appear, choose, click OK. This change is lost if one quits the program. If satisfied with the drawn repeat, use the selection tool to isolate the final motif.  The new working image after cropping to selection:

Drawing in repeat instructions reproduced from the manual Starting with the single triangle: block alignment Standard brick alignment using offset in pixelsPillar repeat also using offset in pixels Other offset options through the use of fractionsPlaying with mirroring positions, producing a minimum 2 by 2 repeat,  the result looks akin to the pillar repeat drawing above, but tiling again to check for alignment may yield surprises that can be viewed as design features or errors,  Changes to mirroring arrows may be made when drawing in repeat on the top left of the window as well  Once an image is drawn in the repeat of your choice, if only the Random option is used, with new picture left unchecked, the pencil may be used to draw on pixel cells, and changes will be made across all repeat segments. Each step may be undone individually. Many of these functions are paralleled in Gimp symmetry drawing.
The possibilities are endless. As always, good note-taking helps in being able to reproduce your chosen process with new images.
If you begin drawing a repeat using a single color on a white ground, then decide you would rather work in only black and white, simply double click on the foreground color, the palette window will appear, choose the new color, and all pixels in your repeat will then change to the selected one Repeats may be built in a more controlled manner using the image duplicate menu, its symbols immediately reminded me of the Passap Alter Direction options: choose a simple repeat to start with. Here a diagonal line was drawn along the center of a square, the bottom half bucket filled a half drop was added and the repeat was tiled to test alignment The duplicate tool enables the repeat of an image or part of an image in a fast way. All duplicate tools with the exception of Mirror X-1 and Diamond work similarly to the drawing in repeat tool if the new picture option is enabled. The mirror X-1 works the same as the normal mirror, except the last pixel of the image is omitted from the image there is also the option for Y-1, here both mirroring options are in use, note the areas in both that retain double pixels, Eliminating those double pixels can be achieved by cropping. The first mirror is for Y-1, the cropped image is tested for tiling by drawing in repeat Drawing lines: use the straight-line icon button to activate the tool, select the line thickness by selecting a number of pixels to be used then move the mouse pointer to a line starting point on the canvas and press the left side of the mouse, dragging it until the line is of the desired length and angle. When the line is at that desired length release the mouse.

A=1 pixel, B=2, C=4 with line dragged and released randomly, D= the line was moved and the mouse was not released until the steps were all the same size. The thick lines option works only at line width 1, which will keep the single pixels connected If you double click on the line icon, the Straight-line icon is activated. Now you can draw horizontal, vertical, or diagonal lines. If you move a mouse horizontally—it doesn’t need to be perfectly straight, the drawn line is horizontal. If the angle between a line and the horizontal axis exceeds the angle of 23 degrees, the drawn line will be diagonal at 45 degrees. If you move the mouse toward the vertical axis, the line will be drawn as a vertical line. The straight-line tool may be used to draw clean diagonals. If the paint tool is then used to fill spaces between some of the drawn lines, the line tool reverts back to the original and will have to be reactivated if you wish to continue using it.
Returning to patterns with repeat constrained
A: a new file is created for drawing a punchcard repeat 6 stitches wide by 60 rows high
B: a freehand drawn pattern
C: the motif is drawn in repeat, X4 in width to match the 24 stitch repeat, X2 in height to get a sense of vertical alignment  D: as long as the new picture option is not checked, the image allows for live pencil drawing, E, with additions which may be edited and undone if needed. Work until satisfied, screengrab the enlarged image if the goal is to use it as a guide to punch cards, scale print it to an easy-to-follow size. Electronic machine knitters use the Tools, Find repeat option to isolate the minimum programmable final repeat, exchange colors if needed The same process, using an 8X8 repeat drawn in repeat X3 in width to 24 stitches and X5 to 40 rows in height meeting the punchcard minimum height Again, electronic machine knitters use the Tools, Find repeat option to isolate the minimum programmable final repeat, exchange colors if needed

Many knitters find inspiration for knit designs in weaving drafts. The Arah Youtube video on developing drawing such repeats shows an option for preview in the draw in repeat window not available in my present version of only the ArahPaint. The resulting working repeats are likely to be large. Reset allows for changing repeat mirroring arrangements. Using find the repeat may help develop a sequential series of repeat segments in different sizes, producing different tiling effects, and the option of hand selection of even smaller areas followed by cropping and processing is always possible.
A sample effort producing a tenfold repeat of the original: Finding the repeat first on the complete resulting new image on left and testing its tiling, followed by finding the repeat again, cropping to the selection and tiling that as well on the right If the goal is to knit a scarf, 72 stitches wide, crop either repeat to a chosen 72 stitches in width, tile in length in either program to visually check alignment. If knitting in DBJ for approximately 1200 rows is the goal, one may obtain a visualization of the results ie for 1296 consecutive rows. A black pixel border could be added to the 72 stitches by copying and pasting the image on a larger canvas that will accommodate that border, or the border may be added by filling in pixels vertically to the edges of the original. Some repeats to play with: the 120 X 96 png  Its shorter, top half  The bottom half, 120 X 48, isolated in Gimp, tiled in length X4 to get a sense of some of the possible differences I cI can see the process becoming addictive once a single personally pleasing starting repeat is developed, and its, in turn, becoming a possible source for collections of designs

COLOR EXCHANGE
In the process of reviewing old Passap files in cut format, the conversion for some of them to .pngs using Graphic Converter on the Mac was successful but left me with oddly colored images that would, in turn, need conversion to black and white for 2 color knitting downloads to other machine models. I have had limited continued success with the color exchange in Gimp. Also, pixel-based images drawn in color in spreadsheet programs such as Excel or Numbers might need far less and quicker editing using the Arah option including reducing “clean up” with pencil tools.
Reviewing the palette tool, from the manual Double-clicking on colors in the palette area will lock them, if this is unintentional, simply double click on the same color again to undo.  The color exchange was easy and straightforward with self-drawn images in the opening palette when creating new documents in Gimp. It failed when working on a segment of published patterns. The Arah manual helped me find the solution. Converting the images from true color mode to color palette mode: the original image and its palette, this is not a “correct” working repeat, Converting for use with an expanded palette
To change the color of the foreground, double click on it, choose black from the upper left corner of the colors window, the image and its foreground color will change accordingly.  Repeat the process with the background color changing it to white, saving the file yields a quickly created png for use in downloads to programs such as img2track Testing with a repeat segment from another image The successful exchanges Spreadsheets such as Excel and Numbers are familiar to many as design tools for developing knit repeats. If colors are used, one is faced again with the necessary reduction to black and white pixels if the intent is to work in only 2 colors. The maximum of 3 and 4 colors per row in machine knitting are handled differently depending on the program used for download. Color exchange reduction with 2 images drawn in Numbers using more than 2 colors:
This repeat would work fine with a reduction to 3 colors, but the proof of concept uses a reduction to 4 colors for both repeats. The two shades of green will need to be exchanged separately, each shade is processed using the sliders on the far right, also note the crosshair.  A spreadsheet pattern for different end-use  to exchange the red the cross-hair was moved to the bottom right, the slider up to the top

When scaling small repeats in Gimp in height only I found the results to have errors, seen in these images, while ArahPaint will multiply the motif cleanly only in height when needed, seen here with the original multiplied both X 2 and X4The Arah scaling appears to be quicker and far more accurate also when used on some published images that would require a lot of clean-up after resizing in Gimp. That said, when working with very large images Gimp offers the opportunity for controlled scaling to any size, keeping the image aspect ratio or not. This reference is described in translation as a pattern design course for Silver Reed knitting machines.  The publication offers many large-scale repeats that are suitable for punch lace, but also for what translates to “braided patterns” which when studied may be intended for fair-isle with enormous floats or for DBJ. No stitch and row counts are given, the goal is to match the manual 54X56 stitch and row count.
The published swatch photo, obviously not a thread lace pattern The initial scanned page segment on the left is 2160 stitches in width, 1588 rows in height. The isolated, cropped, repeat is shown to its right In Gimp, reducing colors: A converting to indexed: B Use scale image to desired dimensions, checking first that values are a full multiple of the expected final repeat pixel count. If not, scale first to a full multiple of each value with aspect ratio off (broken chain link), then scale again with aspect ratio on (intact chain link), edit with a superimposed grid, cleaning up the repeat: C.  Save the final image, C, open in Arah, check set the number of colors, there should be only 2 colors in use, Add a third color, white, to the palette, click on the + symbol, use sliders to convert the magenta to white, click OK single click on the yellow above to place it in this selection, double click on it use sliders again to achieve the white, click OKThe final window prior to saving the BW image ArahPaint will also scale larger images in pixel units. Resizing may be achieved through the use of the image menu Resize option, or simply clicking on the appropriate tool, also copied here in the window that will appear. The chain link, circled in the bottom right, left whole retains proportion, broken by clicking on it will allow for scaling differently in height and width as in this instance I found the final Arah scaling to be less accurate and requiring more clean up than the repeat obtained using both programs

My first attempt at developing a pretend repeat to later be used for chevron 24 stitch tuck stitch :
A: using straight lines, draw several after determining the spacing to be left blank between them, here they are not all intended to match. Bucket fill the stripes intended to be knit stitches, reactivating the straight line tool after each fill
B: when satisfied with stripes and shaping, crop the original to 12 stitches in width
C: using drawing in repeat, mirror to create a 24 stitch shape. Save images along the way in case any “wrong” selections are made, draw in repeat (not shown) at least X 2 in both width and height, looking for errors in alignments D: correction is needed a the top of the repeat E: after your best shot, draw in repeat once more, leaving the setting at random, edit any wrong pixels using a white pencil, the edits will happen across the repeat
F: the new repeat
G: drawing F in repeat makes it appear correct
H: making the repeat as small as possible for use on electronic machines; the find repeat tool does not work on every repeat, particularly very small ones, and it works seamlessly at other times or will require only small adjustments. It is worth testing on images and keeping its use in mind. Here it makes a selection, the image is cropped to the selection, saved, and drawn in a larger series of repeats to check the alignment. Planning a repeat suitable for a punchcard, the uncropped repeat F is opened in Gimp, and pattern fill is used in white areas to ready the file for tuck knitting. The image is then map tiled to check alignment once more, and if satisfactory, it can be saved, ready to be knit The process can be so quick that it can be easily repeated to make new adjustments to meet our needs.
Making things work to get a “cleaner repeat”: the pattern fill is 2 rows wide by 2 rows high, so having both black and white areas of the design a multiple of 4 is a place to start. In the above, the shape outlines are in single row steps, so it is inevitable that the 4-row fill is episodically cropped by single pixels. Doubling the height of the initial single step repeat in Arah begins to solve the problem. In keeping the 24 stitch width restraint, the result, a now 56-row repeat,  will now have variations in the width of the black pixel areas which will produce knit stitches on a tuck ground  With experience, one can quickly imagine ways to clear errors and alter images. Electronic machines free us from repeat width constraints. Widening the zag repeat to 48 stitches, working in Arah, check vertical alignments first, edit intersections whether in a tiled image or the original, ultimately the 48-stitch by 80-row repeat is opened in Gimp, filled with the tuck pattern, and saved for knitting Pattern fill may be accomplished in ArahPaint using brushes made from selection and then enabling those brushes with bucket fill. This functionality is shown in this video: https://www.youtube.com/watch?v=3uacuqK5SjA
The technique illustrated here with a screengrab from the video offers a very interesting alternative option for those who enjoy working with dithered color-reduced black and white images. Working on a possible tuck repeat using only Arah Paint: draw and save the image you wish to superimpose on the ground and save it. I chose to use the color red for visibility. Draw a new image, keeping magnification constant, ie using 0 for 1000 X. Draw a repeat unit for the brush you wish to use, choose repeat from the View menu, click on the stamp icon shown outlined in red, and the available brush will appear immediately below it Use load recent to retrieve the shape that is to be superimposed, say no to saving changes. Make certain the superimposed color is in the background-position, and that the brush box is checked. Using bucket fill to place predetermined patterning behind the shape   To prepare the pattern for download, use Find Repeat, Crop to Selection, change the red to black for knit stitches on a tuck ground, and save the image for a knittable 2 color result The same process may be used to develop a design placed over a lace mesh ground. The final superimposed shape, however, needs to be white rather than black to produce knit stitches, and the final repeat may need to be shifted along its vertical axis to suit the brand machine on which the knit will be manufactured. Brother lace designs begin with a row containing black pixels, end with two blank rows. In Studio lace knitting, the reverse is true Lots of knitters appear to be interested in large, nonrepetitive images. Depending on the machine used and its memory, the repeat may need to be split horizontally or vertically. Before electronic machines, many art-to-wear pieces were created knitting repeats broken down horizontally into the punchcard widths, completing the height of each panel and then joining the strips together. Nowadays there are online tools for many tasks including dividing large images. For DIY, in the first instance, Arahpaint is used to split the “large” file in half horizontally, the resulting image saved. The action happens from left to right, so to achieve the split for the second half, the full-size original is flipped horizontally, split, and flipped again. Followers of my blog have seen the images of my friend Rocco recurring intermittently over the years. Dividing the image horizontally  The same may be done vertically in a matter of seconds beginning with Image, Halve Y, and then using the mirroring tool to flip the image as needed

Color separations: the critical difference in the use of the Arah rectangle tool from that in Gimp is that it cannot be used for sequential selections of pairs of rows in color separations such as those for DBJ or mosaics. In those instances, the Arah image, scaled to the appropriate height may be saved, then opened, and processed in Gimp. For DBJ with each color in each design row knitting twice, design the shape and scale in length in Arah, save and open in Gimp for the separation, see post on working with Gimp update for Mac  Mosaics: draw the desired repeat in Arah, double it in height, save the image, open in Gimp and proceed with mosaic color separation The color separation, in turn, is very easily and quickly changed to all black and white using color exchange in Arah,

The method for color separation used for mosaics

The sources of inspiration from hand knitting or industrial knitting machine designs are endless. There are many features that simply cannot be duplicated, sometimes compromises can be reached that can achieve only imitations of the original. To my mind when knitting garments or long pieces the greater the degree of automation, the less likely one is to have patterning errors occur, in ribber fabrics, they are also more complicated to correct than single bed knitting.
I recently came across a pin of a Ravelry hand knit pattern which led to my return to this topic once more, including perhaps the addition of more colors. The plan is to create a repeat which may be knit using color changes every 2 rows. Each design row knits each color twice, so the standard built-in KRC separation is not a consideration, though the same cam settings may be used in those fabrics as well.
The required color separation has been discussed in several posts on the various forms of DBJ, a review:
The initial test repeat is 18 stitches by 44 rows, designed using 2 X 2 blocks, to begin with. How it might appear knit in fair isle:  Transitions in charting visualizations:
A: FI repeat with pattern progression in two-row increments
B: every even-numbered row beginning with row 2 is color reversed
C: B repeat is doubled in length to 18X88 for initial samples
D: repeat adjustment for a first try at introducing 2 additional colors End needle selection is canceled, the first and last needles are in work on each side on the ribber knitting every row, the first preselection row is from right to left, cam buttons are set after the left side is reached. Knitting in these samples began with the blue yarn in the number 2 position in the color changer. The ribber remains set for knitting in both directions throughout, the images on the right do not reflect the amount of surface 3D textures.
with the main bed set to tuck in both directionsLock settings are easier to achieve on the Passap than switching out cam buttons in Brother machines. This was knit using 4 carriages. Color one knits with the main bed set to tuck both ways, color two knits with the main bed set to slip both ways. The slip stitch reduces the width of the fabric considerably Here each color alternately tucks and slips. The choice of cam buttons matters, tucking first from left to right, slipping from right to left, with cam buttons set COL after the first preselection row This last cam setting appears to my eye to produce a texture “close enough” to the inspiration fabric. Attempting to add more colors: the repeat, D, is still 18 X 88 but is now shifted slightly.  Somehow the slip cam button was not set, so the knit carriage tucked in one direction while knitting in the other. I am vaguely reminded of illusion knits. Considering altering both the color choices and placements again. A way to imagine exact color change placements beginning with solid colors repeats once more, which can be followed by new color separations. The existing repeat may be reduced further to 18 X 64, eliminating some of those extra rows in the center of the chevron shape  The new BW image, tiled: Whether or not the design is intended to retain chevron shapes in alternating textures, actions may be plotted pre knitting in any way that visually makes sense to the person designing the pattern and tools available to them. Reversing the png so that the more textured stitches will begin with the color in yarn position 1Using either repeat, color changes now occur after every 32 rows knit. Another color change location clue is in the needle selection change above and immediately following the red border in the chart on the left.  Adding colors can be planned cautiously or allowed to happen randomly depending on the preferences of the designer and end-use. Ribber fabric designs are not visible until several inches have been knit, too late to catch color sequence errors. Some machines allow for memo placements or sounds to help track color changes, but only within the initially programmed repeats. A quick spreadsheet can provide customizable checkboxes or added information. For an attempt to retain chevron shapes in different textures: When using 3 colors, rather than 4, the texture of the zigzags on any specific color, will vary in placement. It is easy to change colors in any chart to approximate those that will actually be used in the knitting.  Proof of concept: each of my yarns is slightly different in both thickness or fiber content from the others, which can be a drawback in resulting textures. As in any 2 color dbj, if 4 consequent rows are knit in one of two colors the positive and negative portions of the image reverse, as seen at the top of the swatch. The green was not intended to be used originally, the white yarn simply ran out. Such accidents at times may provide pleasant improvements. There is bleed-through of each color behind the other in the tighter knit areas as well which contributes to visual color blending, noticeable even in the areas with fewer tucked stitches. Splitting zig-zags into triangles, working color 1 with color 2, followed by color 3 with color 4 pairings A PDF including row numbers and space for notations zig zag
An editable Excel spreadsheet created as an export from numbers zig zag
For Mac owners a Numbers doc. zig zag
A simpler repeat suitable punchcard owners as well using only 2 colors The test swatch and observations: patterning was begun with color 2, yellow.
The yellow yarn is 12/16, the maroon is 2/15 in thickness.
The triangle, because slip and tuck stitch settings are used, is compressed in height, while there is enough tuck happening to still make the knit wider.
The pattern is 24 stitches wide, the swatch was knit on 40 needles. Smaller swatches are fine for testing tension and colors. If committing to larger pieces, tests on at least 100 stitches by 100 rows are needed for gauge calculations in any double bed work or very textured patterns on the single bed.  On some occasions when a far larger number of needles are in use, problems may turn up that require going back to the drawing board in terms of items ie tension settings, weight used, etc.
A: patterning was begun with thicker yarn, the yellow, in color changer position 2, both yarns are 100% wool
B: KCI, end needle selection on, a 2 color “beaded” edge is created
C: KCII, end needle selection canceled, patterning occurs on end needles
D: transferring to the top bed and using the standard latch tool bind off for these fabrics is far too tight  The tiled repeat, 24X48, does keep the stitch quality constant for both colors, Assumptions based on optics of tiling are not always accurate clues to potential patterning errors, here those darker lines are part of the actual design Continuing on a 24 stitch repeat, the original design may be rendered at double height and separated once more, doubling the separation height to 96 rows There are days when either or both machine and knitter need a break. At the start of the first swatch, the cam buttons were not set, resulting in plain knit stripes. At its top, the purple did not get picked up properly from the color changer, and the knitting of course fell off the machine. On a second try, the same issue happened again with the purple yarn. Multiple incidences of such events were fondly nicknamed “dropitis” by my students. The test is on 24 stitches, the width of a single repeat, the triangles are much more balanced in size, this knitter is putting this pattern to rest.  Another try at the diamond shapes that began this topic. The first .png when tiled appeared to not have enough space between the shapes, was amended to this the differences when tiled the color separation can happen completely within Gimp using color invert the white yarn is an acrylic, slightly thicker than the purple toned one. Sometimes simply exchanging yarn positions can change the qualities of the overall fabric. The repeat begins with 2 blank rows. To achieve the tighter white shape as opposed to the honeycomb purple one, at the start of the repeat that color needs to be in use on rows where knit stitches happen as the KC, set on slip to the right, knits needles brought forward to D position. Red in this chart segment marks pertinent rowsBoth with hand knits and commercial knits because of the hand actions possible on both sides in the first, and as many as 4 beds selecting and knitting on the other may be in use at the same time with more complex needles as well, there are fabrics that are difficult or even impossible to duplicate. There often are obvious differences in the results, but the journey may still yield results that are pleasing and worth pursuing. Another even more complex inspiration from a sweater attributed to Falke, Spring 20 collection, using similar stitch structures, but in addition, also transferring stitches between beds exposing a purl striped ground.

Tuck lace trims and fabrics 3

The term lace is often used in publications to refer to fabrics created with techniques other than the familiar hand or machine stitch transfers. In turn, the ribber may be added to working most of the fabrics with varying degrees of complexity. Some variations are possible only on specific machine brands, at times possible in others with adaptation and addition of other techniques. Many combination fabrics may be achieved, mixing carriage settings or adding hand techniques. A list of common terms applied to “lace” that include tuck patterning:
Hand transfers: used to create eyelets, possibly in combination with pattern stitches out of work, and moving stitches singly or in groups
Tuck and lace: transfers combined with tuck stitch patterning
“Lace like patterns”: possible in machines such as Brother and Passap, which allow for the same stitches tucking in one direction, slipping on the return of the knit carriage to its starting side. It matters which function leads in the pattern
Tuck lace: tuck setting in both directions with specific needles out of work
Ladder Lace: worked with columns created by needles left out of work, tuck being an option in the knit portions
Punch tuck rib: every needle rib combined with tucking pattern on the knit bed Drive/ drop stitch lace: stitches start on either of the 2 beds, loops are picked up and dropped on the opposite bed
A list of the headings for most of the tuck stitch variants covered in my posts is now added to the start of my blog index

Once a stitch has been tested,  unusual yarns, including wire may be used Getting back to basics: a punchcard sometimes supplied in factory packs provided with machine purchases, is shown here in 1/3 of the minimum 36-row card repeat, while the minimum electronic repeat is outlined in red, measures 4 stitches by 4 rows Adding needles out of work by simply choosing to cast on and working on every other needle it does not matter whether even or odd needles are in use, the pattern will be identical but simply shifted over by one needle. For frequent color changes, make the first preselection row toward the color changer to start with, keep notes as to where the repeat color selections happen as experiments are expanded, evaluate color choice as a third or even fourth color are introduced Though casting on and binding off both need to be considered for extra width, having sections of the repeat knitting in plain knit will help sort the needle arrangement and loop structures when tucked knits appear similar-looking    The repeat on any tuck row can help test the number of rows a particular yarn will allow before the number of loops in the needle hooks become too many to knit off well. The added texture, or elimination of any, could be used in borders or occasional horizontal portions of the knit Some of the concepts in the visualization of more deliberate color placement through charting was discussed in the post: Single bed tuck and slip stitch fabrics 2: adding color
A starting repeat from a Pinterest image inspiration: the blue yarn will knit on every needle the third tuck row on the machine the fourth tuck row with needle preselection for the first all knit blue row one blue row knit Accommodating those blocks of knit stitches in the pin also changes the repeat to six stitches by 6 rows, making it usable on punchcard machines as well Two from one: the same tuck repeat was altered by changing the needle out of work arrangements. Slub yarn may be used but changes the value of the lines formed by the floats created in the needles out of work gaps. In my classes, I encouraged students to create long swatches testing out their patterns in a variety of stitch types with color changes as well. Thet can serve as a visual reference to duplicate effects when time has passed. Here the tuck pattern, not suitable for FI at all, is tested as DBJ, followed by needle transfers between beds and adding the tuck setting. There is a dramatic difference in width, the wool yarn has a lot of “spring”, wanting to narrow when at rest The self-designed stitch structures may be further changed visually and complicated in terms of execution by adding changes to the ribber setting so that it does not knit every rowPublications for electronic machines do not always include pertinent instructions, but they will include out of work needle diagrams below each appropriate repeat. The gray cells represent white squares, which correspond to non-selected needles but also in this case to out-of-work needle position areas where open spaces are created. The 4, 6, 8 stitch repeats are also usable in punchcard machines. These are from the Stitchworld pattern book, all with the exception of 282 are to be used with needles out of work

“Crochet” meets machine knitting techniques: working with short rows

Some previous posts exploring hand techniques that might be considered to fall in this family of stitches:
“Crochet” meets machine knitting techniques: tuck lace trims (and fabrics) 1
“Crochet” meets machine knitting techniques: tuck lace trims or fabrics 2
“Crochet” meets machine knitting techniques: working with “chains”
Search for “wisteria”
“Crochet” meets machine knitting techniques: working with short rows 1, June 2017 began to explore some of the fabrics presented in this category in a Portuguese language publication I do not speak or read the language, so my swatches are best guess efforts at producing similar knits. Attempting literal translation is not always helpful, for example, guidelines at the beginning of the pub:
“CLARIFICATION FOR THE EXECUTION OF THESE POINTS
A: in crochet stitches, the scheme is repeated across the entire width of the machine
B: in the “crochet ends”, braids and flowers, thread only the needles. Islands as indicated by the symbols in the scheme. Alternative: in crochet stitches of gallons and flowers thread the thread only on the needles as indicated in the diagram symbols
C: when starting to weave the car must always be on the right side unless the symbols in the scheme indicate otherwise, for example, crochet stitch #9
D: in crochet stitches count a career whenever the tip of the wire stay at the other end of the machine
E: the tension must be adjusted according to the stitch and thickness of the thread to be used, in general voltages 1-3 are used.”
Some familiarity with larger-scale patterns in this family can help visually with duplicating them independent of the written original language directions.
These fabrics share common hand technique movements across rows, singly, or in pairs. Similar structures are not presented in numerical order in the pub but will be here.
The yarn choice makes a critical difference both in managing the knitting and in how blocking, or not, affects the finished fabric. The knit carriage travels many times across each stitch as the technique is worked, with possibly pilling, so softly spun yarns should be avoided.
Clean the machine of any leftover fibers, while avoiding over-oiling which may leave dark streaks in the finished product.
Cast-ons and bind-offs need to be very loose to compensate for the fact that the completed knit will have considerable sideways stretch. Chain cast on 2 in work, 2 out of work, end with 2 needles in work
bring all stitches out to hold except for the first 2 stitches on the right
COR knit 8 rows
push adjacent pair of needles away from the carriage into work position, knit a row to left
COL bring previously knit pair of needles out to hold
knit 7 rows, end COR
bring adjacent pair of needles opposite carriage into work, knit a row to left, end COL
COL when the last pair of needles is returned to work knit 8 rows
reverse shaping: bring the second pair of needles on left into work, knit a row, push the first pair of needles out to hold, continue the process for the desired length
The yarn used is a 6X18 rayon, a “no memory” yarn that changes considerably with pressing. The arrows mark an operator error in tracking the sequence, top and bottom edges are obviously narrower than the resulting mesh.  Number 11 is a close relative but worked on every other needle The rayon used in the previous sample, and a 2/8 wool, were less successful than a 2/11 acrylic in knitting the swatch. The stitches need to be as tight as possible while also needing to be able to knit off properly
make a very loose chain cast-on on an even number of needles, then drop every other chain, taking every other needle completely out of work, and ending with a needle in work
bring all stitches out to hold except for the first stitch on the right
I believe the directions are given for knitting only 2 passes, I preferred the look with the count doubled to 4, so, COR knit 4 rows
push adjacent needle away from the carriage into work position, knit a row to left
COL bring previously knit pair of needles out to hold
knit 3 rows, end COR
bring adjacent pair of needles opposite carriage into work, knit a row to left, end COL, knit 3 rows
COL when the last pair of needles is returned to work knit 4 rows, continue with
reverse shaping: bring the second pair of needles on left into work, knit a row, push the first needles out to hold, continue the process for the desired length
In the top part of the swatch I knit 8 rows at starting and ending sequences, feeling the sides were tight, 6 may be the best answer
bing off very loosely after the last stitch is worked for 4 rows
The same directions apply in this instance, the first sample worked with no needles out of work I added 3 chains between cast-on and bound-off stitches, making for a better top and bottom edge. The difference in width is highlighted on the bottom right, where I missed doing so between two stitches. At the end of each row, prior to reversing direction, I knit 6 rows rather than 4, end with 4 rows only on the last needle prior to binding off. The swatch was not steamed or pressed.
This knit begins on every needle I cast on chaining over 2 needles, followed by two extra chains where the ladder is expected, cast-off also with two extra chains in ladder spaces. The knit sequence is similar to the previous swatch, but needles are now moved in pairs
COR work first 2 stitches for 2 rows
push two needles on left into work, knit one row to left
COL *push first 2 stitches to hold, knit one row to the right
COR bring next two stitches on the left into work, knit one row to left
COL push previous 2 stitches to hold, knit one row to the right**
bring 2 stitches on left into work knit one row to left,
repeat across the row
when the last pair of stitches are left, COL knit two rows on them, and reverse shaping. Ending each sequence with two knit rows will produce fairly straight sides, knitting four rows on end stitches, except prior to binding off,  may echo the movement of the in-between spaces and make the ladders at the sides more visible Eliminating those ladders or floats, here eyelets are created where stitches are held for two rows. Care needs to be taken if stitches are dropped or other patterning errors are made in order to retain the correct pattern. Cast on and bind in this instance were executed with single chains added in between those on needles in work.
Version 1:
COR with the first 2 needles in work, knit 2 rows
COR bring one needle on left into work, knit 1 row
COL bring one needle out to hold opposite carriage, knit one row
COR bring one needle on left into work, knit 1 row
COL bring one needle out to hold opposite carriage, knit one row
repeat until there are 2 needles left in work, knit 2 rows
reverse shaping
end with 2 rows knit on the last pair of stitches before binding off
Version 2 adds 2 rows knit on every needle between holding pattern reversals, the fabric grows in length far more quickly
Cast on from left to right on every needle
COR knit 2 rows, bring all needles except for the first 2 on the carriage side out to hold
COR with the first 2 needles in work, knit 2 rows
COR bring one needle on left into work, knit 1 row
COL bring one needle out to hold opposite carriage, knit one row
COR bring one needle on left into work, knit 1 row
COL bring one needle out to hold opposite carriage, knit one row
repeat until there are 2 needles left in work, knit 2 rows, end COL
COL push remaining needles into work, knit 2 rows on all needles
COL bring all needles except the first 2 on the left into work, knit 2 rows
reverse shaping, ending with 2 knit rows on the far right
COR push all needles into work, knit 2 rows on all needles
COR bring all needles out to hold except for the first 2 on the right
repeat all
end with 2 rows knit on the last pair of stitches before binding off

chain cast on 2 in work, 2 out of work, end with 2 needles in work
worked in 2 pairs, 4 needles at a time
COR knit 6 rows on the first two pairs of stitches on the right push pair of needles on the left into work knit one row push first 2 of needles out to hold knit 5 rows CORpush next pair on left into work, knit one row  push the third group  on  its right into hold position, knit 5 rows across remaining  4stitches bring a new group on left into work, knit one row
bring the pair to the far right out of work
repeat  process across row
when  the last pair of needles on the left is pushed back into work, knit one row
COL knit 10 rows, bring the third pair of needles into work, knit one rowPush the first pair of needles out to work, knit 5 rows, continue with reverse shaping.
If the pattern is to end on the right (or left), knit 6 rows on the last 4 stitches and stop, otherwise when the opposite side position is reached, knit 10 more rows before reversing and continuing in the pattern.
Tracking rows worked: 7 ladders are created in each space, 12 on each end. Depending on yarn and stitch size watch to see that even tension is maintained particularly on the first 2 stitches worked on each side.
The swatch is shown before and after some light pressing, the arrow marks some looser stitches on the side edge.

Latch tool cast on from left to right, chaining 4  in no needle, future ladder spaces
COR with the first 2 needles in work, knit 2 rows
COR bring the first needle on left into work, knit 1 row to the left on three stitches
COL bring the first needle of the previous pair on the right out to hold, knit one row to the right on two stitches
COR bring the closest needle on the left into work, knit 1 row on three stitches
COL bring the second needle of the previous pair on the right out to hold, knit one row on two stitches
repeat working on 3, then 2 stitch sequences until there are only 2 needles left in work, end COL
COL knit two rows, begin  reverse shaping by putting one needle into work on the right, knit one row on three needles
COR bring the first stitch on the far left out to work, knit one row on 2 needles
continue reverse shaping, ending with 2 needles in work on the far right
COR knit two rows on 2 stitches, repeat and continue the process until 2 stitches are left in work on the left, and reverse again
end fabric with 2 rows knit on last 2 stitches in work
latch tool bind off with chaining X 4 in ladder spaces
keep an eye on sequences, the floats are created in series of three, with experience knitting similar patterns, errors become easy to spot during is knitting Shell shapes: #4 and # 20 directions are given in the 2017 blog post Some of the trims in this pub may be far more easily and quickly executed using tuck stitches.

Numbers and GIMP: online punchcard patterns to electronics 2

There is a Russian online site offering a huge range of punchcard designs. The question on how to convert the site files for use in electronic machines surfaces periodically and did so again recently in FB groups.
My posts with information related to this topic:

A Russian language tutorial on converting the punchcard images using DAK
A recent offering on navigating the site in English, begin viewing on minute 5
The site link http://perfo.12rus.ru/index.php?
The translated site link 
The options in English for working with published cardsThe help menu is available after the card is chosen Designs are presented in pages that list them from longest to shortest row counts for the complete repeats. Punchcard users can reproduce holes as given. There is also an option for entering a new design and it appears, in turn, one may be able to generate a separation for its use in DBJ.
Beginning with a smaller design intended for machines with 12 stitch repeat restrictions simplifies the view and processing of it for newbies. The published patterns are offered Silver Reed ready. The option for converting the cards for use on Brother 260 renumbers it with the appropriate location for the number 1 row marks required by the operation of the different brand’s card reader. Toyota versions are also available. Making the holes larger is a boon to reproducing the drawing correctly regardless of end-use. Splitting the card into segments is helpful when using factory blanks with a 60-row maximum repeat, and often also when processing the image for use on electronic machines, which is affected by screen size views available to the software user. For some reason, I found the commands erratic when working on the translated version of the site, fared much better in the original language publication.
The chosen card image may be dragged onto one’s desktop. I use Numbers to create my tables. The 2 all-punched rows, marked with blue arrows, and any standard vertical rows of holes on each side of the provided designs need to be isolated and eliminated. This is a 12 stitch repeat required for use on some machine models or useful when using a thicker yarn on every other needle to achieve the same design, every other vertical row is blank. A: the table with cells 20X20 sized to match the number of rows and stitches in the original. The card image is arranged in the back of the table with the constrain properties option unchecked in its image-arrange menu. B: cells corresponding to marked holes are filled in with black since the final goal is to create an indexed BMP. Using and holding down the command key during cell selection helps perform the coloring cells in action on groups, clicking on any cell again while still holding the key down will deselect the fill. Release the key, choose the fill-in color, repeat, and continue until the holes in the full design are filled in. C: click and hold command key, select every other blank vertical column marked with letters at the top of the table, the blank vertical rows are selected, release the command key, right-click on any of the same letter selections again, and choose to delete selected columns from the pull-down menu or after marking the rows directly from the table menu at the top of the screen. Eliminate all cell borders. C: the result showing how the pattern will appear when used to program fair isle.  Screengrab the final image surrounded by extra white cells, open it in GIMP. Change the mode to indexed BW, crop the file to content thus excluding any extra white cells, scale to the original design’s 24 by 74 dimensions. Punched holes are now pixels; export the knit-ready BMP.
Using the filter, map, tile option allows one to check on horizontal and vertical repeat alignments for any errors, and begin to imagine how the repeat might appear on a finished piece. Color exchange used on the BW BMPs converted to RGB mode helps visualize the knit using specific colors. On the far left below the final BMP is shown magnified X 800 with a superimposed grid, then filter-map-tiled to 48X148 size. It is followed by a color reversed version of the same. The remaining images illustrate the result of using the color exchange option, beginning with the BW BMP repeat converted to RGB mode.  Getting a preview of how a finished garment might appear, here the tiled version is 192 pixels in width and one may glean some idea as to whether that repeat should ever really be used in a sweater or even a blanket. Further image scaling or cropping can happen based on the knit gauge. A very quick rendering imagining pattern and color placements using a simple sweater outline Collections of every other needle repeats for processing with a similar approach may be found in these volumes, available for free download

In machine knitting, the word lace is used in categorizing a large variety of knit fabrics. The terms include:
simple lace, executed with carriages that transfer and knit in a single pass
multiple transfer/ fashion/ fancy/ lace: executed wit carriages that transfer only
lace and fine lace combinations
fine lace
tuck stitch combined with transfer lace
tuck/ pull up lace
transfer lace combined with weaving
punch/thread lace
ladder lace
punch tuck rib
drive/drop stitch lace
If one explores the openwork patterns on the site, the second selection for 24 stitch cards, the 20 pages of repeats do not differentiate between the lace categories, so the onus is on the visitor to determine proper card use. In addition, the option for switching machine brands does not readjust for changes required for the pattern to read correctly in the alternate card reader. As an example, transfer lace cards are shown with blank starting rows, ending with punched holes, a Studio brand feature, and in some cases with a punched row ending with blank rows, a Brother feature. If changes are made in machine brand selection, the only adjustments in the new image appear to be made to the numbering sequence, but not to the punched or unpunched starting and ending rows.

For punchcard users or enlarged views: printing the PDF breaks the repeat into segments required if one is using individual 60-row maximum length factory cards and not a punchcard roll. On the far right, the difference in relative size between a factory punchcard and the PDF image printed without any adjustments.  Filling in the dots with a black marker renders the to be punched holes more visible through the card, making marking prior to punching easier and faster.  For a better, printed match size, after capturing the image from the PDF for a single page outside image edges, opening it in Gimp, cropping it to content, it is then possible to scale the results to measurements of a factory punchcard equal in width and adjusted for the number of rows in the image. My card required print measurements were 14.1cm by 26.1. Scaling executed with aspect ratio is too long.  breaking the chain-link, removing size constraints The result with printing to match the card stock measurements was extremely close to the desired size, useful, but hard to photograph  Entering patterns: the translation Working with the Russian menu The saved pattern will be assigned a number, in this case, 9831In the 24 stitch repeat FI area of the site, enter the assigned number into the search field on the upper right changing the view to larger holes if preferred, the option also becomes available to separate for 2 colors DBJ  translated to “recalculating for 2 fountains”  Screen grab or save pdf, depending on needs.

Gimp update for Mac 2

The previous post on this topic: 2019/10/07/gimp-update-for-mac/
I have been spending more time exploring version 10.22 and am becoming more familiar with new features and design options. There are slight variations in behaviors depending on the Mac OS version. Windows updates happen more frequently. GIMP 2.10.24 for Mac OS is now available.
Gimp has a wide range of paint tools The most commonly used in creating repeats for knit design are Pencil, Paintbrush, and Bucket Fill.
The Pencil tool is used to draw freehand lines with a hard edge. The main difference between it and the Paintbrush is that although both use the same type of brush, the pencil tool will not produce fuzzy edges.

Present experiments are placed in alphabetical order. Topics:

BRUSHES AND PATTERNS
There are many very good videos on using multiple versions of GIMP on Youtube. Most focus on working with very large images in huge numbers of colors, and brushes or patterns in the tutorials are often larger than the maximum stitch count on our home knitting machines capable of electronic download and with needle counts of 180-200. In addition, punchcard machines have a 24-pixel width repeat constraint. The content of such published material and tutorials can be overwhelming, but isolated techniques for the required binary bit mapped knit scale are easy to sort out.

Many knitters designing small repeats use very simple programs and enter pixels singly or copy and paste in small groups. Some simple, quick functions in Gimp can simplify and speed up the progress considerably. Punchcard knitters may use the same techniques to set up their 24 x X custom length repeats and tile the results to visualize how they line up when knitted in multiples.
Some content paraphrased from the online Gimp manual: in GIMP, a pattern is a small image used to fill areas by placing copies of side by side. You can use them with the bucket fill tool. They vary in size, are used for filling regions by tiling, that is, by placing copies of the pattern side by side like ceramic tiles. A pattern is said to be tileable if copies of it can be adjoined left-edge-to-right-edge and top-edge-to-bottom-edge without creating obvious seams, such patterns are used in standard knitting repeats. The same effect may be obtained by using the Filter, Map, Tile option on the drawn image.
With the bucket fill tool, you can choose to fill a region with a pattern instead of a solid color. To make a pattern available, place it in one of the folders in GIMP’s pattern search path which includes two folders, the system patterns folder, which you should not use or alter, and the patterns folder inside your personal GIMP directory. The .gbr (“gimp brush”) format is used for ordinary and color brushes. 
Photoshop ABR brushes are also easily imported for use.
Pressing the refresh button causes GIMP to rescan the folders in your pattern search path, adding any newly discovered patterns to the list. This button is useful if you add new patterns to a folder, and want to make them available without having to restart GIMP.
GIMP includes a set of 10 “paint tools”, which, except for the ink tool, use the same set of brushes. The brush pixmaps represent the marks that are made by single “touches” of the brush, which is desirable in working with knit scale bitmaps. Brushes can be selected by clicking on an icon in the brushes dialogue, the current brush is then shown in the Brush/Pattern/Gradient area of the Toolbox. Clicking on the brush symbol there is another way of activating the Brushes dialog.

When you use the Copy or Cut command on an image or a selection of it, a copy appears as a new brush in the upper left corner of the “Brushes” dialog. This brush will persist until you use the Copy command again. It disappears when you close GIMP.
Building a personal brush pattern library on Mac: open software preferences locate folders on the bottom left, click on plus sign aside folders icon at the bottom left, it will change to a minus sign, and folders become visible select brushes, two options will appear. If a proper choice is made for the addition of pattern files, a green button will appear single click on the filing cabinet icon on the right,  a familiar Mac finder window will appear double click on the patterns folder, its own window will appear,  right-click in the window below the last entry, a smaller window appears, choose the add new folder option. It will appear as “untitled”  and will be added to the existing folders, rename it “my brushes” or any other choice, and the new folder will be added within the brushes one Its place in the brushes list will be determined by its initial letter, the contents are in alphabetical order. For future use, any saved brush may be dragged and dropped into the named personal pattern folder icon, or into the folder after it has been expanded or opened in its own window. My opened brush folder After brushes are added, the refresh button below the brush dockable dialogue may bring them up without having to restart the program. After saving these 3 images as .gbr files and placing them in the appropriate folder they appear as available for use  To install .abr files on Mac:

create a new photoshop folder within the Gimp brushes one
Download the chosen files, drag and drop the images or folder from the downloads folder into the chosen Gimp one, they will be available after a Gimp restart
The free files I tested were very large in size, did not scale down to use for knitting cleanly, and even though they appeared to be BW they opened as RGBs making the conversion to BW indexed quite dithered. They are composed of assorted leaves and snowflakesWhen exporting self-drawn brushes, the option is offered for adding spacing surrounding the shape, here a 10% addition was chosen Patterns may be saved in a similar way. Since GIMP 2.2 you can use .png, .jpg, .bmp, .gif, or .tiff files as patterns.
Saving patterns from large to tiny may be achieved using the same method as in saving brushes. To save personal patterns, instead of choosing the file cabinet icon in preferences, one may choose the folder icon, following a similar series of steps to those above, including verifying contents of the newly created folder Use Windows, Dockable Dialogues, choose Pattern. The patterns will show on the right of the Gimp window and are viewable once you click on the fill window below the tools on the left as well.

Open the image to be filled
Click on the paint bucket tool, select the Pattern fill type. Click on the paint bucket, then on the pattern you wish to use on right, hover over the canvas with the paint tool, click on it and the image will fill in the chosen pattern.
Or click on the pattern icon, scroll through to the desired pattern, click on it, then on the paint bucket tool, hover over the canvas with the paint tool, and click on it to fill.  The + or _ option scales the size of the pattern view, it is handy when tiny or very large repeats are chosen. The canvas for the pattern fill needs to be large enough to accommodate the pattern in repeat.
If the fill fails, check to see that the bucket fill mode was not somehow changed from normal to one of the many other options Here the skull is used to fill a 400X400 canvas, an even multiple of its size If the canvas is not in a full multiple of the whole pattern, part of the repeat is cropped  Using the same rose image tiled using the Filter, Map, Tile menu produces similar results when full multiples of the image pixels are not chosen, ie. here the tiling is on an 80-pixel wide canvas as opposed to a full multiple of 25 ie 100  Designing tiny repeats:
Begin with the image in black and white indexed mode. 
To draw my repeats, I used 1800X magnification, with grid view, exported the files as png, and dragged them into my own Gimp patterns folder.
If the goal is full punchcard repeat illustrations, then by default the width of the image to be filled needs to be 24 pixels wide, and a minimum of 36 rows high. If working with tuck stitch, punched squares are black pixels, unpunched ones the white, creating the tucked loops. Using the bucket tool to fill the image is accomplished with a simple, very quick stroke  The rectangle tool may be used to isolate a segment of the first repeat and the area may then be filled with a different pattern. Brushes may be resized as needed, pasted on the previously filled image, guides are helpful in their placement.  Grids and Guides: my view was magnified X 2800, the canvas measured 24 X 36 pixels.
Magnification may be set using the pull-down below the image window, where any number listed may be chosen or typed in and set by hitting the return key, or by choosing the zoom tool. Click only on the image, the zoom is applied to the whole image. If the pointer is used, click-and-drag the mouse pointer to create a zoom rectangle. The biggest dimension of the rectangle will correspond to the size of the image window. You can get to the Zoom Tool from the Image menu through Tools, Zoom, or by clicking the magnifying glass in the toolbox Anyone needing an adjustable grid superimposed on an existing image may use the Configure Grid command to set the properties of the grid and display it over the image while working on it.
One can choose the color of the gridlines, and the spacing and offsets from the origin of the image, independently for the horizontal and vertical grid lines. The configure grid dialogue:  The five different grid styles: Intersections, dots: the least visible, a simple dot at each intersection of the grid linesIntersections, crosshairs: a plus-shaped crosshair at each intersection of the grid lines  Dashed: dashed lines in the foreground color of the gridDouble dashed: dashed lines, where the foreground and background colors of the grid alternate, looks the same as above when the image is in BW indexed mode. It is also hard to discern the separate colors in RGB mode because the dashes are so small and so close together,  Solid: shows solid grid lines in the foreground color of the grid Foreground and Background colors: in RGB Mode, click on the foreground color to select a new color for the grid, click OK Spacing: for use illustrations see GRIDS: OPTIONS
Width and height: select the cell size of the grid and the unit of measurement
Offset: moves the origin of the first cell, by the fault the grid begins at the coordinate origin, 0,0
The Snap to Grid command enables and disables snap to grid. When snap to grid is enabled, and a selection is moved or placed, the grid points pull on it when it approaches making accurate placement easier. If the magnification is high enough, the placement of your pencil or brush will be outlined in a dotted line. Here the snap to the area for a 3-pixel pencil is shown highlighting its possible placement location.  This command is found in the image menubar through View, Snap to Grid.

GUIDESto configure guides, simply click on one of the rulers in the image window and pull out a guide, while holding down the mouse Left Button or side. The guide is then displayed as a blue, dashed line, which follows the pointer. Releasing the mouse will place it.  As soon a guide is created, the “Move” tool is activated and the mouse pointer changes to the Move icon.
You can create as many guides as you like, positioned wherever you like. If the grid is set to a 1X1 square pixel default with a line border, at any point the Image, Configure, Grid option may be used to change the ground view  To move a guide, activate the Move tool in the Toolbox, then click on the guide (it will turn red), and drag it to a new location. Click-and-drag the intersection of two guides to move them together. Create as many guides as needed, positioned appropriately for the design. To delete a guide, simply drag it outside the image. 
Holding down the Shift key moves everything but a guide, using the guides as an effective alignment aid. You can remove all the guides with the Image, Guides, Remove all Guides command.
Working on punchcard repeats whether in designing for cards or to create a BMP for electronic download using a published repeat, guides may be set to outline 6X6 blocks as seen in factory issued Brother punchcards, or to create custom templates.  For example, lace designs have few pixels. Horizontal guides may be added or moved at intervals between repeat segments, making certain the two knit rows are left blank as one continues in entering the proper pixels. The vertical guides help in orienting and locating the pixels in design blocks to match the source.  With guides in place, pattern fill may be used, adding shapes using the tools, or brushes to place motifs. A sample of a knit repeat using the rectangle tool and the paint bucket tool combination to create filled rectangles placed in relationship to guides, creating a tuck pattern with interspersed plain knit rectangular shapes Built-in or custom brushes may be superimposed on a bucket-filled ground. Create an image in the desired width and height, here 24 X 24, magnify at least X 800 for a grid view.
Fill with a pattern.
Place the chosen brush on the patterned ground, adjust the size and placement of the brush until satisfied, save the image.
Consider the end-use for the pattern. For example, the designs below left would be suitable for tuck stitch, the same designs would need to be color reversed if the plan is to use them to knit thread lace. Both the original and the new image should be set to BW indexed mode. Developing a brick version of the repeat is easy and quick. With the original image open, create a new image with the same width but twice its height, 24X48.
Set the magnification for both images to the same number, adjusting the number of both if needed so the longer canvas is in full view.
Configure the grid as preferred on the new image, make it visible. Snap to grid is useful, may not be necessary when working in such a scale.
Copy the full starting image and paste it on the bottom of the new.
Guides may be put in place to adjust for the pattern shift in the top half of the new image. A single, center guide, in this case, was sufficient.
The full image copy is still available, align and paste it again, its left side to the right of the center guide, anchor it.
Paste its right side to the left of the center guide and anchor that in placealso. Undo and repeat steps if needed.
Check the alignment of the full repeat by map tiling, if satisfied, export it as PNG or BMP for future download.COLORS EXCHANGE
Color exchanges to test designs in different colorways may be made easily and quickly using the program. To test the concept begin with a simple repeat already tested for tiling originally saved in indexed black and white colors This icon shows the default foreground and background colors  The black is the foreground color, the white is the background.

Using such small images I often work in 800X magnification. Open the image, choose sizing, scaling, or magnification if necessary, convert to RGB mode then from the colors menu choose map, color exchange. The color exchange window will appear. Here the white “from color” is left undisturbed. Select the dropper next to the “to color”, then click on the image on the color you wish to change, a palette window will appear. Make your choice, the color exchange window will now have substituted the chosen color for the black, click OK, and white design areas are now changed to the chosen blue globally. The process may then be repeated with the second color if desired.  The color exchange window will show white as the default “from color”. Click on the white bar, choose black from the palette window or use the dropper to select black from the image. The from color will then appear as black. Repeat selection with the dropper from the right of the “to color” bar on any black pixels in the image, choose the color from the palette window to replace it, the color exchange window will display the new “to color”. Click OK, job done. The process may be repeated multiple times on the same design or used on large-scale ones, giving one some idea as to whether or not to really commit to the estimated colors. I recently had reason to review old PC files from my Passap knitting days and came across several cut files that when converted to png format appeared in colors rather than black and white, leading me to experiment with color exchange again.  The image for the first experiment is part of a crib blanket by Cheryl GilesThe process: do not alter the original image ie. by resizing, which seems to change the color mapping responses
load the image in RGB mode
working with the foreground color, click once on the white, use the color picker to choose a color, in this case, orange, a palette window will appear, click OK, the background color will change accordingly,  double click on the now orange background to call up its palette window, keep that window open, go to colors filter, map, color exchange
double click on the from color, the white, in the exchange window
match its values to the saved palette window working from the top down, you may find some of the remaining numbers self-correct
in the original image orange, is now exchanged for black continue, repeating the process with the alternate color, in this case, yellow. At that point, the in-process image will appear as solid black. Click on the black in the exchange window to color twice, choose white from the palette selection, click OK, and the conversion is complete. It is possible to colorize images originally drawn in black and white. The color exchange options will remain fixed throughout the process. The image may be worked on continuously and exported when color exchanges are completed, or saved and imported again after each step. The color exchange here happens consistently on the chosen background color, changing that quickly becomes familiar and easy. There are times that the repeat being processed will turn black onscreen, trust in the process and continue.
The default color exchange window using color options in the default palette. The steps for changing the background to red: the image will turn black as you work, click on the TO color selection picking a color from the default palette to replace the white, in this case, the red, you can click OK, but do not close this last window if you want to continue, the color change will be lost Changing the black to white in summary Export the image. The transitions: Developing custom palettes in order to visualize different colorways while using the same repeat:
load the image,  right-click on the paintbrush icon, choose palette editor, this window will open with selections for possible palette choices click on your choice, then click on the palette icon, your color choices will appear, click on the white, to create a new background color.It will change it to the chosen value in this window when you click on that. The new color choices appear in the palette in the future unless a choice is made using reset it to the original. Two selections may be made for new colors at the same time, but the map, color exchange option will continue to work on the background color only. These were my choices for added colors. Continuing to work with color changes, changing the white in the BW repeat to blue the black to orange My success with series of other images in using color exchange has been spotty. Online forums reveal this is a recurrent issue with no clear solutions. Suggestions include stipulating that the cause may be the version of Mac OS in use. Color reductions using ArahPaint achieve consistent results easily and quickly. There are advantages to hybrid conversions. 

COLORS THRESHOLD: see GRIDS OPTIONS
GRIDS: OPTIONS
Punchcard users may use this method to visualize which holes to punch, though this particular repeat would need to be reduced in stitch count in order to be usable. Similar charts may be adapted and used for other textile techniques such as cross-stitch or even filet crochet.

Grids help with the precise placement of pixels when designing using pixels to represent stitches and rows. The grid is not visible until it is activated via the View, Show Grid option in the Image menu. To create a custom grid, the Image, Configure Grid from the Image menu brings up a dialogue that allows you to do so. Snap to Grid causes the pointer to “warp” perfectly to any grid line located within a certain distance. In most instances, when drawing repeats a 1X1 pixel grid works well on a canvas magnified enough for it to be visible when filling in cells, I recommend a starting magnification of X800.
Anyone needing an adjustable grid superimposed on an existing colored image may now adjust the grid size to suit while viewing the resulting changes. The beginning image and grid size both need to be large enough for the grid to be visible. Use the show grid, configure grid commands  The intact chain-link fixes the width and height aspect ratio of grid cells Considering the possible smallest repeat, breaking the chain link, changing values progressively while viewing the results brings one closer to matching units  The image itself may be scaled concurrently to tweak grid border alignments. The final grid size below is 18X18,  the image size is shown after scaling from a width of 277 pixels (with a broken link at that time) to a final 270 pixels in width The screengrab of the above center, with a superimposed new grid; note the image, in this case, was also offset for better placement, a 3-pixel pencil was used to isolate the border of the possible smallest repeat Using Filter, Map, Tile to check alignments  The repeat reduced to 12 stitches, suitable for punchcard, and tiled to check alignments. Translating the colored image to BW indexed may take several steps and some clean-up if only Gimp is used to process it. With the colored large-scale isolated repeat, the image is opened in Gimp. The Threshold tool transforms the current layer or the selection into a black and white image, where white pixels represent the pixels of the image whose Value is in the threshold range, and black pixels represent pixels with Value out of the threshold range. It may be activated from the pull-down colors menu or from the toolbox.   The color image will temporarily disappear, adjust levels. Scaling to repeat size: check the image size, making certain the present dimensions match a multiple of the final repeat count for stitches and rows. If adjustments are required, breaking the chain link allows for each count to be adjusted independently from the other. In the final scaling, use the closed chain link, adjust numbers, magnify the repeat, checking it with a superimposed grid for any missing or out-of-place cells. Check the alignment, then save the single repeat, which in this case is 14X14, ready for download Color separations: there are occasions where very small repeats need to be scaled in height only for color separations. I have found such scaling to be inaccurate using the option, such as here, both of the small, single repeat, and in scaling its tiled version. The triangle motif was used in many of my early posts on color separations for DBJ and its backing options.  On a long enough canvas, the grid may be adjusted to 1 pixel by four in height. With that number of cells filled in with black in this case, if the 1X4 unit is captured with the rectangle tool, it will appear in the brush menu and will be available for use with the pencil tool for drawing with single strokes until one quits the program unless the unit is saved for future use as described via preferences  Using RGB mode, the two-color redrawn image is redrawn, A. The grid may be adjusted to 1X 1 again, B. Using magnification, I often use X1800, pairs of rows may be selected for either color invert or value invert color options. The first will add a third color, seen in the chart bottom, the second will yield a 2 color image, seen in the chart top, B.  I have had no success with using keyboard commands for the action using my OS, find it easier visually to deal with the three colors than with the 2, especially in longer repeats. C: the extra color pixels in the rows with black pixels are filled with white. D: the third color pixel rows are filled with black. D the final repeat may be color indexed to BW and saved for download.  The appearance of the final repeat when color reversed Another comparison of the 2 options for altering every other pair of rows in the specific color separation for a mosaic repeat. There is less filling in of cells with a different color, but in large files especially, I feel the result would become far more visually confusing to track.

SYMMETRY PAINTING
Information summary from the online manual on working with symmetry:
you can access this dialog from the image Menu bar through Windows-Dockable- Dialogs-Symmetry Painting, its icon appears below at the top right A drop-down list offers four options. As soon as you check a type of symmetry, axes appear as dotted green lines in the image window and you can start painting with the brush you have chosen.
The default position for the symmetry axis is the middle of the image window. You can place the axis where you want using the Horizontal axis position and Vertical axis position.
Disable brush transform: when you transform the drawing, the brush itself will end up transformed as well. For instance, in a mirror transform, not only will your drawing on the right of the canvas be mirrored on the left, but the brush itself is obviously “flipped” on the left. If for some reason, you want the drawn lines to be mirrored (or other transformation) but not the brush outline itself, you can check this box.
“Tiling” is a translational symmetry, which can be finite (with a maximum of strokes) or infinite. In the latter case, it is the perfect tool to create patterns or seamless tiles, at painting time. This mode covers the image with strokes.
Interval X Interval Y: these are the intervals on the X and Y axis, in pixels, between stroke centers.
Shift: this is the shift between lines on the X-axis, in pixels.
Max strokes X, Max strokes Y: these are the maximal number of brush strokes on the X and Y-axis. Default is 0, which means no limit, according to the image size.
Using a large image, testing few iterations, helps one understand the process. The pepper brush is provided in the program and is used in the tutorial on the Gimp site. Most such tutorials are intended for working on far larger and higher resolution images, while knitting is binary and at the opposite end of the spectrum in scale and required image size. The original brush is 220 pixels in size, the maximum number of needles per pixels on standard machines programmable at one time is 200. For exploration, any of the built-in brushes may be used, I began by scaling the pepper to 50 pixels, then moved on to a self-drawn, equal size flower motif. When choosing canvas file size, consider a multiple of the brush size. Drawing repeats uses the pencil tool.   Working with potential knit repeats the scale is reduced further. Magnification is useful for the evaluation of repeats. The smallest repeat segments for use on electronic machines may be isolated. The filter map, tile option easily verify how the repeats line up overall. Cropping a 24 stitch width and tiling that also visualizes the suitability of the repeat for use on punchcards with the 24 stitch limitation.  Grid view helps identify any need for “clean up”.
This rose is 24 stitches wide by 25 rows in height Open the chosen file in Gimp. Create a new file in a canvas size considering a multiple of the original.
When the Copy or Cut command is used on an image or a selection of it, a copy appears as a new brush in the upper left corner of the “Brushes” dialog. This brush will persist until you use the Copy command again. It disappears when GIMP is closed.
With the single repeat opened in Gimp, magnified several times, click on the image and use the copy command. The image will appear in the symmetry dialogue. The position may vary depending on whether the program has been closed and relaunched between episodes of testing the process. Create a new file, large enough to accommodate a multiple of the original number of pixels, adding pixels for spacing between or above and below designs, set the magnification to the same number as that of the clipboard image, left-click on the brush icon, choose the image saved in the clipboard and a type of symmetry and accompanying settings, click on pencil tool, the motif will appear as on the above right, paste the image on the new canvas, undo and repeat setting adjustments until satisfied with the distribution of motifs.
Some ways of varying repeat positions working with motifs in networks were illustrated in the post To develop a brick repeat I began with a canvas twice that of the original rose, 48X50 pixels, isolated the smallest repeat, used the filter map tile option to test its all over alignment The 24X50 repeat: To decrease crowding, using the original image, the new canvas is now 40X60, with the shift decreased from 12 to 8 pixels. The result did not tile properly when mapped, using magnification 800X with a viewed grid the final repeat, 29X60 was isolated Being more deliberate with the math leads to a full, successful repeat 

Working on the gridded image, drawing straight lines to isolate color change areas in chosen colors followed by flood filling, one may begin to visualize changing the ground color behind the motif repeats Using that small triangular 8X8 repeat open in Gimp, or draw any small shape if designed by hand, remove the grid. Before using it as a brush, reduce mode to 2 colors, magnify X800. Open a new file. I found the latter needed to be increasingly small as well for the repeats to be placed accurately. After tiling using symmetry, filter, map, tile from the filter menu to check for multiple repeat alignment.   Again, preemptive math will yield images that avoid further processing. It is up to the user to recognize any problems,  the repeat here needs to and can be isolated correctly from the file on the left, it is actually only 16 rows high. Here the adjusted repeat is created on a 24X16 canvas with the same symmetry settings, and filter/mapped/tiled There may be multiple ways to achieve the same result with each motif. Here the same repeat is executed two different ways  The above repeat was cropped and adjusted to 16 stitch width and 8 row height, the file saved, and the process repeated  Using symmetry once more, remember to adjust the pencil size.  For the pinwheel shape I was unable to use color exchange successfully on the above images, but with the saved 2 colors indexed red and white repeat both img2track and ayab appeared to load the repeat successfully. The map color exchange was successful using the steps described at the top of the post when beginning with the repeat drawn in a black and white version.  

A different approach, experimenting with built-in brushes: symmetry preferences remain constant, the brush size is reduced. The results are best if the canvas is created in black and white indexed mode to start with, and shapes reduce with varying degrees of success. The numbers reflect brush sizes in each dot pattern. Different types of symmetry may be applied to the same image

For afghans or wall art, if one is attracted to large shapes, drawing in mandala symmetry on large canvas size is as gratifying and immediate as when using a spirograph, the results happen in seconds, these were drawn using 32 points. Steps may easily be undone along the way as one attempts to make the images more complex.

My first non repetitive DBJ explorations on 930

WORK IN PROGRESS

I created large-scale nonrepetitive image garments very early in my knitting career using Cochenille Bitknitter and Commodore computers linked to a Passap E6000. Over time my focus changed considerably, with any production knitting moving onto accessories as I began to make items for sale in galleries and in shows, most often single bed on a Brother 910. If knitting is a primary source of income, one needs to consider production time management, material costs, and what the local market will bear in terms of pricing.
A post, written in 2018, began to explore two-color-dbj-non-repetitive-images-electronic-kms/. At that time I did not have a machine model capable of using img2track.
An orphaned 930 entered my life, and with rare exceptions, over the past few years, my blog sample swatches have been knit using img2track, which I have found easy, reliable, with any programming errors due to the operator issues including learning the differences from 910 programming and remembering to actually use them.
No matter how long any of us have been knitting, there can be many aaargh moments both in everyday knitting and when exploring new techniques.
I have a supply of lovely 2/48 cash-wool in royal blue, black, and grey. Three strands worked predictably on my punchcard machine in a series of my spiky scarves, shown in progress on the machine. Nearly all my previous dbj pieces have been knit on a Passap E6000. The 930 experience for such repeats is new to me. With some help from Tanya Cunnigham in reviewing steps required when using img2track, I returned to cellular automata repeat saved years ago.
I encountered problems with the triple strands of blue not feeding evenly, here both colors were picked up by the changer accidentally, I realized the issue, trying to unravel the row of knitting produced this That provided an opportunity to decide I preferred the reverse color placement as well as wanting a thicker ply for the white, resulting in twice the fun with 2 colors, and another scrapped sample Switching the white to a single-ply thicker yarn made its stitch formation far more manageable. The blue however seemed to have a single strand of the three with a propensity for catching on gate pegs. I tried tension adjustments, the usual tips in managing static. At about row 1,000 out of 1288 rows, I realized I had an issue with both yarns being caught on gate pegs. In trying to lift the stitches off, the yarn broke but gave with no immediate visible clues, the dropped stitches and a lovely hole, as a result, appeared when knitting had progressed far enough below the current knit rows. On the left, the work is shown still on the machine, while on the right, it is off the machine, and in the process of a patch job with a temporary accessory and stitch holder in place. I was able to achieve a reasonable repair on the knit side, but the birdseye pattern on the reverse is a bit scrambled. For folks that are not familiar with electronics and are curious, the 930 has the smallest memory of the later Brother electronic models. My pattern repeat is 74 stitches wide by 644 rows in height. The user manual explains: the KH-930 takes just a few seconds to load the track because the memory holds only 2 KB of data (about 13000 stitches). Later models have a much larger memory (32 KB). The KH-940 and KH-950i require 42 seconds to load a track. The KH-965i and KH-970 load only the requested pattern, so the loading time depends on the size of the pattern. img2track indicates progress as the data is sent to the KM. When the pattern has finished loading, the KM should beep, and show the green READY light and a 1 in the display (for row 1). The program automatically chooses Selector 2 for a single image and centers it. You may change this by using the normal pattern selecting process on the knitting machine, choose Selector 1 for all-over patterning, or use Selector 2 and choose a different location on the needle bed to center the pattern. If your pattern was divided into more than one track, you will have to load successive tracks when completing the previous track, specific instructions are given for programming subsequent tracks. My pattern was broken down into 4 tracks.
The cable used for downloads to the machine is used externally, no alterations to the machine’s hardware are required as when using Ayab on the 910. The pattern is stored in the machine, so the computer needs to be awake only during downloads, not constantly as in programs that use knit-from-screen.
Each track for 2 color DBJ using the KRC built-in separation is entered in numerical order as a new pattern with first-row preselection from the left to the right and first row knit from right to left toward the color changer. If the repeat is not planned for the number of needles in use, any position or change to all-over design needs to be re-entered, and the KRC button must also be set again.
Cam button settings are set according to the chosen dbj variations for either or both beds. End needle selection is usually canceled. In some patterns using it can create an interesting beaded edge on either side, which is worth testing on small samples to determine one’s preference.
I like to plan my pieces beginning with the dark color, plan my repeats with the deliberate placement of both colors, and any scaling in the pattern BMP prior to download, using Gimp. I also prefer to have color 1 as the dark, color 2 as the light. The default in the Japanese DBJ separation uses the light color, white squares, as color 1. Out of habit I color reverse my images so my first preselected row from right to left can just knit my black squares rather than the white, and I can continue my motifs as I intended while having machine prompts for each color also match.
Pausing knitting is easy as long as the needle selection is not disturbed. Ending with COR avoids any confusion about which color should be used next. Starting outside the set mark, turn the machine back on, and simply continue in pattern with appropriate color changes.
Tanya Cunningham manages and moderates the membership, settings, and posts for the Img2track – For Machine Knitters group on Facebook.
These were her tips and reminders to me for handling pauses in knitting immediately after the following track in the sequence is first downloaded: let’s say that either some needles got pushed in or repositioned, or for whatever reason, you don’t have certainty that the last row of needle selection is reliable, and you want to “re-select” the last row before you knit it, the last track you knitted should still be in the memory, even though you’ve completed that part of the pattern. 
1. Push all needles back to Pos B. 
2. remove the yarn from the feeder, disconnect the K carriage from the R carriage. 
3. Turn Change/Selector knob from KCII to N (NOTE, this will cause your PART buttons to de-select) 
4. press BOTH PART buttons. 
5. Move K carriage to right. No needles will knit, since all are in POS B, and both PART buttons are depressed, AND no needles will select, since you’ve moved the change/selector knob to N, and the memo will not record any advancement of row. (However, if you’re using your mechanical row counter, it WILL record a row, and one on the way back so plan to either disable the ribber arm or plan to turn the counter back 2 rows)
6. Now you will have to re-select the last row of needles for the track you’ve most recently knitted. First, verify that KRC is activated. Now, you will have to push the up/down arrow buttons to select the very last row of the pattern which will be an even number, and color 1. Depending on whether the carriage was moved in such a way as to activate the sensor enough to cause the memo to advance, you may be able to simply use the row that’s showing, but even beginning the movement of the carriage may advance it. To be sure, what I do is to advance (in this case to Row 1 Color 1), and then back up one row, using the arrow buttons. 
7. Move your Change/Selector knob to KCII, be sure to move outside the turn mark. Verify KRC; memo says last row, color 1; both PART buttons in. Now, move your carriage right-to-left, to select the last row of the previous track. 
8. Load color 1 in the carriage, load next track into the machine, KRC selected.
9. Now, as you knit to the right, you will be knitting the last row of the previous track, and selecting needles for the first row of the next track. Carry on.

In terms of generating cellular automata math-based patterns, the Wolfram website is a great place to explore repeats. A player, temporarily unavailable to Mac users is presently available, allows for the download of interactive demos in .cdf format. In terms of knitting any of the repeats, the most suitable appear to be ones that are generated in black and white to start with. Not all are, and at times changing the mode to bitmapped in programs such as Gimp can produce a glitched effect. Though the latter may be interesting and desirable to some, I prefer clean lines and diagonals along with identifiable shifts in the scale of any triangular components.

I am often amazed at the speed with which time passes, previous related posts: 2015/12/09/cellular-automata-charts-for-knitting-etc/

Weaving drafts may also serve as inspiration for knitting repeats.

One may explore segment placement and color reversals easily using programs such as Gimp. There is also potential for exchanging colors to get a sense of how the pattern might appear in different colorways My planned test repeat is 76 stitches wide by 556 rows high.
