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. Posts with related content: 2015/11/28/weaving-drafts-as-inspiration-for-other-textile-techniques/, and 2018/07/02/numbers-to-gimp-to-create-images-for-electronic-download/. These images are extracted from a draft for an advancing twill. 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.

To mesh or not to mesh 8, more Numbers meet Gimp

A recent FB post led the discussion to this repeat from a 910 mylar, which does not have the immediately recognizable format of the Brother lace patterns if viewed in a small screengrab such as this. The repeat is included in Ayab test patterns. The full mylar collection and user manual may be found here http://machineknittingetc.com/brother-kh910-pattern-guide.html.
The segment including the lace pattern Brother was the first to allow programming from multiple areas on a single mylar sheet. Starting and ending stitches and rows needed to be entered, I got used to drawing boxes for each pattern as seen on the upper right, reducing errors in future knitting. The red lines on the copy highlight the repeat’s border. Mylars were read 13 rows down, punchcard machines7. The equivalent of arrow markings on lace punchcards are provided in the column on the left, which extends over the top of the drawing space by the same number of rows, allowing it to remain visible above the card reader even as the top of the mylar patterning area is reached.
The design is actually created from isolated areas of a mesh repeat discussed in a previous post. The lace carriage is used for 2 passes and then for 4 alternately, as indicated on the left side of the punchcard. The 2 passes will result in transfers to the left, the 4 make in transfers to the right. This repeat, usable in nonelectronic models, appears in my pre-punched factory basic packs as both #17 and #20. Depending on the electronic model or the software used to download patterns designed for lace, the final image may need to be flipped horizontally. This is true for use on my 930. Creating a template for mesh using numbers: begin with a table with square cells in numbers larger than you might need, ie 24 by 54. The method for doing so has been explained in previous posts. I happen to prefer cell units that measure 20 points by 20. The smallest repeat unit for use on any machine is isolated, shown bordered in red, is 4 stitches wide by 6 rows high, and drawn onto the template. The group of cells in the repeat are selected. If one hovers over any side or top and bottom borders of it, a yellow dot appears. Clicking and dragging on the yellow dot will repeat the full selection to the right, left, up, or down. Here the move is to the right The whole group is selected, and dragging on the yellow dot once more, the whole template can be filled Beginning at the top or bottom of the table, hide all blank rows. Using the command key during the selection process will allow this to be done on the whole table at once or in groups of rows at one time; 36 of the 54 rows are hidden.   At this point, there are a couple of choices. One is superimposing a solid shape. Using a contrasting color makes it easier to sort out its placement the color may be replaced with white in the spreadsheet,
unhide all rows, and the lace pattern is ready for the final steps before using Gimp The other option is to unhide rows on the colored table, screengrab as usual after removing cell borders. Open in Gimp, crop to content, eliminate the cyan row by filling it with white. It was intended as a place holder for the last row in the pattern, is not part of the final repeat.
In this instance, I used mode, indexed, to the maximum of 3 colors.
Choose the color to alpha option from the colors menu.
Using the dropper tool select the color you wish to be made clear, click OK. Create a new image of the same size.
Copy and paste the color-reduced image onto the new one.  Dotted lines will appear in areas that had the color removed previously. Clicking anywhere in the window outside the image anchors the paste and make those dotted lines disappear. If that does not work, select the rectangle tool before doing so. The file is then ready for final scaling. The last image is in RGB mode once more, converted to BW indexed, scaled to 24 by 54, and exported as BMP or choose any other format ie png, etc. to suit your needs.
Responses to alpha selection can vary depending on the original color palette used when filling cells.
Creating a template for drawing simple shapes using transfer lace, it is easier to start out with the transfer grid in a color, rows are hidden as above, eyelet shapes are drawn in black. The rows are unhidden.    In this instance, the red was selected for converting to alpha with the image still in RGB mode, copied and pasted. The pasted image may be anchored in several ways. Using image menu: select merge visible layers, or flatten image; layer menu: select anchor layer, or simply click on rectangle select tool and click again anywhere in the window. Changing the mode to black and white indexed will yield the repeat for final scaling. Each transfer design segment of the repeat is 6 rows in height and completed with 10 combined carriage passes. The lace carriage, LC, operates first, in series of two passes at first, then followed by four, repeating the double sequence throughout. The mylar, card, or computer image, do not reflect the passes made by the knit carriage KC. The latter is set to knit, does not engage the belt, does not advance the pattern. It helps to look at an expanded repeat to understand that indeed, transfers are made in 2 directions.
Referring to design row numbers, not necessarily those on a row counter:
1.  LC preselects for transfers to the left as it travels to the right
2.  LC makes transfers as it moves to the left, no preselection occurs, remains on the left side
3.  KC, moves to the left, completing the first knit row, creating loops on needles emptied by transfers, the pattern does not advance, remains on the same row
4.  KC, moves to the right, completing the eyelet stitches, the pattern remains on the same row, KC then stays on the right
5.  LC moves to the right, no preselection
6.  LC moves to the left, preselects for transfers to right
7.  LC moves to the right, transfers to right, no preselection
8.  LC returns to the left, no transfers or preselection, stays there
9.  KC moves to the left, the pattern remains on the same row
10.KC moves to the right, the pattern remains on the same row, KC then stays on the right Those familiar with eyelet formation in the more traditional transfer lace will notice the differences here, where the geometric shapes are technically superimposed on a mesh whose structure is revealed depending on where the transfers creating them take place. The fabric is easy and very quick to execute since most of it is in stocking stitch. The proof of concept swatch: The design was not planned as continuous, but is easily amended to be so. Here an alternate version is shown, with 2 linear repeats on the left, and a single expanded repeat to its right As for that mylar repeat, this is an image of the shapes with the chart collapsed, eliminating blank rows between black pixels. The resulting partial test used as drawn In fabrics designed this way, using the image as drawn (left), or mirroring it horizontally, does not visually change the result. This does not hold true in more complex transfer lace.
Several large-scale designs based on this method are found in Brother-electro-knit-lace-patterns-3 This random chart from the publication shows a pattern where the number of transfer rows between knit ones has more variation. Again, knit rows are marked in the column on the far left. Those marks on a mylar would remain visible on the outside of the machine, above the card reader as one progresses through knitting. Memo windows or handwritten charts may be the only option for accurate tracking, depending on the machine model and the row count variations. The repeat may also require it to be flipped horizontally. Simply reaching a row with no needle selection does not always mean the location for the 2 knit rows has also been reached. 

Visualizing maze or mosaic potential from tuck or slip stitch repeats

I have written extensively on mosaics and mazes, color separations required for drawing their motifs, and visualizing the resulting patterns while planning slip stitch or tuck repeats. A recent exchange with a knitting friend, Tanya Cunningham, brought up her idea of using Gimp to investigate the potential of self-drawn tuck patterns becoming pleasing mazes or mosaic designs in color. Tanya has worked extensively with img2track, can be found in the FB group and Ravelry. It had not occurred to me to reverse engineer designs for this purpose. Tanya uses Gimp in a different way than I do, I am hoping she will share her process for this purpose when documented.
I have grown comfortable and fast with the combined use of Numbers and Gimp to achieve what I desire in terms of color separations. At the moment, on the assumption that estimating the overall shape is the goal, a black and white processed rendering may be a sufficient representation of the result.

Punchcard books are a great source of “safe” tuck designs. The best are those that have columns one stitch wide by 2 rows high. They are also more interesting if there are areas of solid black. Patterns from publications intended for use on electronics are often color reversed to start with in order to minimize drawing pixels or to make the design easier to read and will have lots of blank areas. Punchcard users would need to punch the ground as opposed to the design, electronic users can achieve the goal by the flick of a switch or a quick software command. For my first series of steps and methods, I am using the repeat that appeared as a knit using different settings in the post on mazes and mosaics from universal patterns.
Presented on the left, the repeat would be suitable only for thread lace or FI with very long floats. Color reverse allows one to use it for tuck and slip stitch, whether in one color or with color changes every 2 rows. The color separation to approximate the result with color changes begins with the same process as that used for designing mosaics. Once the image is rendered as a correct B/W png with no apparent errors, it is copied and pasted on a larger canvas, the mode converted back to RGB. The red cells make it easier to keep track of rows that need to be color inverted. Using the shift key and rectangle tool, multiple pairs of rows can be selected sequentially and color inverted. Beginning the selection with the very edge of the black squares on the left does not interfere with changing the color of the extra columns on the left side of the design. If pixels are added accidentally drawn in any of the 4 extra columns on the left, they can easily be removed when the completed conversion is cropped to selection for the final repeat. The completed color separation can then be bucket filled to match imagined colorsTiling the repeats to imagine the final knit presents the problem that results from working on a square grid and comparing the results to a knit, which usually produces a rectangular one. The representation for the linear patterns produced on the knit side of the piece cannot factor in some of the added distortions created by the stitch type used. I process my images in Pages or Numbers, depending on which document contains my most recent work and happens to be open. It is also possible to perform the final rescale in Gimp. Most knits approach a 4:3 ratio, with gauge variants in highly textured fabrics.  To preserve a clean design, tile and save the original, screengrab the resulting image, load it in Gimp, and rescale.   Repeat the motif for the same number in both height and width when tiling it. The colored versions before and after scaling, compared with the slip stitch swatch. It is possible to produce a rectangular grid to start with on which to draw in Gimp, but the larger canvas size occupies a significantly larger space on the screen, complicating the process. For small designs, however, that may be an option to give one the sense of aspect ratio for the design in the final knit ie in representational FI. To resize the grid in uneven proportions, the chain-link below the spacing values needs to be broken This repeat is designed for an electronic, requires color-reverse. Since it is 24 stitches wide and it may also be modified and used on a card. In this instance, the original marks for rows and stitches are single height. The image is processed, matching the original, rendered double-height, color reversed, and then alternate pairs of rows were color inverted to render the repeat used in the test swatch Once again, the possible change in scale is estimated. The repeat though only 24 stitches wide, is 92 rows high. On the left the repeat is shown as it appears on a square grid, to its right is the scaled 4:3 version, in a pixel count approximating the size of the swatch. It takes a bit of squinting to see the pattern more recognizable in the longer repeat in the larger tile The swatch was pressed, becoming wider than when first off the machine. It was knit using the slip stitch setting, could also be executed in tuck stitch, which would both widen and shorten the fabric and make the purl side more interesting.  The software can provide a preview of the result far more quickly than knitting samples, but again, the previews are only approximations of the scale, and cannot show distortions to lines as one adds more texture.
Repeating the process starting with a diamond shape that as given is only suitable for thread lace or FI with problematic floats,  and with a check tuck pattern that may change in aspect ratio considerably when knitted The proof of concept swatch, knit in tuck stitch, begins to show the distortion by the stitch formations, textures vs plain knit, easily seen at the top edge. The bind-off is around 2 gate pegs in order to allow enough stretch.  Anyone familiar with either or both programs may find this a very quick way to visualize the scaling and moving of motifs within DIY designs and their possible outcomes prior to test knitting

Img2track_multiple colors per row dbj, each color knitting only once

I have recently shared a post on using the heartofPluto separation in Ayab to knit a DBJ 3 color sample where each color was not represented in each row, with each color knitting a single height.  Img2 track at this time does not offer a built-in similar option. There is a FB thread going on at the moment on this topic that can be followed there, Tanya Cunningham has shared a document on this topic. I am using the same repeat as in my Ayab tests,  with  my color changer in this threading sequence throughout
 The import into img2track shown here for the traditional 3 colors per row setup,
where normally each color in each design row knits twice. Because selection occurs for pairs of rows, the first preselection row is from right to left. To decrease the backing rows, the ribber is set for birdseye. I prefer to have an end needle on each end on the ribber, keeping in mind that the total number of needles in use there needs to be even. The machine provides reminders as to which color should be knitting. My samples are knit using KCI on the top bed. Because the preselection happens twice, it is easy enough to knit in pattern from left to right,  when the carriages have reached the right side, simply use a ribber comb to push all needles back to B. The next color to be used is preselected as the carriages travel back to the left, change color when on left, and repeat.
It is easy enough to develop a rhythm. I used to tell students some things are made easier if one develops a tune to play in one’s head as series of actions. Here I found myself thinking “knit to right, erase (selection), knit to left”. I had tension yarn issues on the right which explain some of the issues on the side edges and changed color 1 to blue for increased contrast. The proof of concept: Speeding things up with color separation, beginning with the method that will have each color, each design row knitting twice. The repeat is 10 rows high, so it is expanded X6 to 10 by 60 rows. In the final result, the second row for each color in the separation is in turn erased. The red was added to make all 3 colors visible while working the separation, avoiding confusion with the white ground. The knittable result as usual is in a black and white png The img2track settings are for now for 2 color knitting, the prompts for the color changes are lost.

The color-changing sequence used was still 1, 2, 3. The design with a birdseye backing The ribber can also be set to knit every row, resulting in elongation on the knit side, while creating an interesting striper backingComparing this version to the birdseye backed one for repeat height Comparisons: HoP, pushing back needles to B, and color separation results. In the latter, the design is likely elongated in part due to a change in the distribution of thinner yarns to larger design areas with no tension adjustments 

Gimp to create text for knitting

Recently there have been many questions in FB forums about incorporating text in knits. The techniques can vary depending on available tools. The most basic method is entering vowel and consonant shapes dot by dot in paint programs, with each dot becoming a pixel or punched hole in the final image. There are some many free downloadable fonts for personal use that produce images that can fairly easily be translated this way, among them:

Notes on using GIMP update for Mac 2019

I had a quick FB share for a first exploration using Gimp:
“I have not previously put much effort into using text in gimp. A quick start: image 200X200,1800 magnification 
view grid, snap to grid, work in RGB mode, not indexed, 
turn off anti-aliasing, it wants to smooth edges. Caution should be exercised when using antialiasing on images that are not in RGB color space. In this instance, ultimately working in lo-res black and white for downloads, you want to keep the jaggies, not average them out. I believe Passap actually has a built-in command to “smooth edges” in images downloaded into it. I have always preferred manipulating the images myself rather than relying on software to do it for me.
start with font size at 12 in the chosen font, increase the font size if letters are too close together, the result is easily changed to black to make it ready for downloads, obviously not an answer for tiny letters. My capitals are font size 12, the other 3 words size 16 to maintain spacing between the letters”Getting a bit more methodical, info from the Gimp manual
Text management, Text tool
There are good online videos on this topic, but they are intended for use in much larger canvases, often using 150-200 as the font size, whereas in knitting that is likely the limit of our canvas size when planning for programming the full needle bed.
I am working on a Mac. From Windows tutorials found on Youtube, it appears there still are differences in some of the content and optics between the two platforms. Gimp is the only program in which I personally prefer and use dark mode. To change the app’s appearance, the selections for dark, gray, or light themes may be made by choosing system preferences, then clicking on theme, and selecting from options available on the right a partial illustration of changes in the grey and light themesText may be activated by choosing text in the image/ tools menu by clicking on the tool icon A in the toolbox or by using t as the keyboard shortcut, then clicking anywhere on the canvas.
Click on the fonts button Aa to open the font selector
or type in the name of the font you wish to use, choosing from installed fonts. Text editing can happen by selecting buttons here or with direct on canvas editing by making the changes within the semi-transparent floating toolbox on the canvas itself.
If you prefer to work with dockable dialogues go to and choose Windows, Dockable Dialogs, Fonts, and options will appear on the rightAs long as a text box is active, making another selection from the fonts menu will instantly change the box content, creating a preview each time.
As mentioned, Antialiasing is best turned off when not in RGB color mode
Hinting
Uses the index of adjustment of the font to modify characters in order to produce clear letters in small font sizes” is helpful in lo-res text intended for knitting Color default is black, click in the box beside Color selection and a dialogue selection box appears for changing it The choices listed at Gimp.org for text directions include the standard right to left, left to right as in most languages, and the following for vertical text  After the text is entered on the canvas, right-click on the inside of the text box to change text direction It is not necessary to work with the layers menu to start with. It is possible to “wing it” to get a starting sense of the process. Scaling and transformations are available, starting on a canvas size less than 200X200 based on needle counts on a standard km provides an ample field on which to play. If the intent is to change the direction of all the entered text, Image/transform may be used. Entering the same text in the same font size in an altered direction can change the overall pixel counts After the chosen text is placed change its mode from RGB to B/W indexed, then crop the image to your chosen size. Export.bmp, the result loaded into img2track and Ayab For a different way to edit, choose Image/Flatten and individual components may be reconfigured on a new canvas to a very different size. This file is now 68 stitches wide, rather than 144 The usual text alignment rules apply in text boxes as well,  left to right using the return key, double-clicking in the box will highlight each letter  activate view grid should you wish to count pixels in each Text center-aligned
Getting more control of the process: after the text tool is highlighted and clicking anywhere on your canvas two things appear automatically. The four little boxes represent the text box, which is dynamic by default, grows in size to accommodate typed text. Anytime you click on the canvas a new text box is created.
To change the size of the text box and you want the text to fit in a specific area, click and drag on one of the lower, small exterior boxes, and release. The box then becomes fixed, the text will move automatically to the next line and is placed according to alignment settings. If the bottom of the text is cut off, click and drag on that small square on the bottom corner or the bottom line of the text box shape to expand its size to include it in full.
Double click on a line of text to reveal those outlines around each letter or click and drag right or left on full words for editing. Click on a single letter space to delete it. Repeat if needed, type in the new letter(s) for a spelling correction or word change.
If following Windows instructions, it is helpful to know the comparable Mac commands pictured here on the bottom left of the Mac onscreen keyboard Use the option key and click on the canvas, and drag to place the text box on any specific area, or also to move all content in an existing text box, choose the move tool then click on any letter within the text box and drag and place. Random placement in the text box will move the whole layer The spacing between the lines and between the letters may be adjusted as well. Clicking on the arrows to change the values here is one option, negative or positive numbers may be used or what appeared easier to me,  the same may be done here A sample of adjustments in line spacing Very small fonts are likely not to have any room for decreased spacing in the between letters in strings of text.

A review of some of the terms used in describing fabrics with raised designs in various patterns:
blistered fabrics: two rows of the main color are knit the same as in standard dbj, but more rows are added and knit with the blister color on only one of the two beds used to create textured pockets. Technically they can be executed in a single color as well as in two colors per row. The extra rows result in the blisters being raised or lifted up from the fabric surface, they are often also referred to as pintucks. These fabrics do not have the width and stretch of many other 2 color dbj fabrics.
When exploring this family of knits, use plain, fairly smooth and thin yarns. This is a fabric where pressing should be avoided so the texture is not lost or altered. For setting the pockets created sometimes slipping a wire or tool through the bubbles will do the trick as for any hems. Simple, bold patterns work the best. Spreading the texture evenly throughout the design will decrease distortions in width. Leaving needles out of work combined with racking can alter the basic technique considerably.
In the two-color version, a double thickness fabric with a crumpled face side and a single color backing is created. The blistered areas are knit in one bed only, the rest is full needle rib with floats from each blister enclosed in the fabric.
Begin with a repeat that is elongated X2, the jacquard separated pattern needs to be double marked. Needles are arranged as for DBJ. For 2 colors the main bed is set to slip <— —> throughout, but the ribber settings need to be changed and set to knit and slip alternately for 2 rows to produce the single color backing.  Good needle condition is a must if occasional stitches are dropped on the ribber they can be repaired when the work is off the machine.
Ripples are created by setting one bed to slip and the other to knit for several rows, then setting both beds to knit simultaneously to join the tucks in repeats. They are selective pintucks, on every needle rib. The main bed is set to slip <—  —> throughout, the ribber carriage is set to slip for 4 or more even numbers of rows, and then to knit for 2 rows (this number may also be varied depending on the specific pattern). This is a fabric that likes to be weighted evenly. Tight ribber tension will help increase the definition of ripples. As in any multicolor fabric, each set of ripple stitches may be knit using a different color yarn.  Some designs tolerate having the main bed set to tuck rather than knit.
Brother machines often are limited to 4 rows knitting on the bed creating the ripple before closing the rib.
Transferring blister stitches to main bed, with a shadow lace tool or a transfer carriage is referred to as “shadow lace”. Adding blank rows in your design makes it easier to have a transfer point to the opposite bed. Using a plaiting feeder will add color contrast.
“Nopps” which are essentially small bumps on tightly textured tuck stitch grounds require careful tension adjustments.

An image was shared in a machine knitting group on Facebook. It cropped up in Pinterest, could be traced back to some Russian knitting forums and a how-to knit query was made
There is an Italian language youtube channel with a throve of machine knitting videos, one on jacquard groffato , executed on punchcard machines, with a companion video on punching the card. Groffato means embossed.
Points to remember: the more needles on either bed knit alone to create the pockets, the more the tension used needs to approach the one for single bed knitting there with the same yarn. Large shapes are best used, represented by white squares /unpunched areas. Punchcards such as ones published with large unpunched areas for thread lace designs or tuck stitches with large punched areas color reversed can work once the principle is sorted out.
The setting used in the video is for tubular/ circular knitting.
The all punched rows in the video actually match rows that would be knit anyway because the main carriage is set to knit in one of the two directions, not slip. Two yarn ends are used, which could result in a fairly dense fabric with limited drape. Switching to a single yarn end can alter both considerably.
In designing your own patterns for testing it is best at the start to keep shapes simple and not worry about repeat variations.  I am working on a 930 using img2track, but my repeat is 24 stitches wide and usable on a punchcard model, its source is another pin. To make the design twice as long, when planning an electronic download, the image can be stretched in the design software or by altering the stretch factor to 2 in img2track. Tiling the design prior to download can help one imagine the potential results in using it for an all-over pattern or what its appearance might be if the repeat is shifted into a brick configuration.
Use a familiar, smooth yarn in an easy to see color. Tension changes alone can change the dimension in the textured surface, so having a “normal” baseline for tensions and “feel” while knitting from previous uses of the yarn double bed gives one a good starting point.
The “flower” image used in my tests is shown here in the original, and then is color reversed so its shape will blister, not the ground. Below it, on the left, the image was stretched within img2track, on the right within my design program which happens to be Gimp. In both instances, the original 24X24 design becomes 24X48 in actual knitting

The tiled image for both a standard repeat and a brick configuration shifting by 12 stitches to the right are not thrilling me, but the goal is to explore the knit technique, modifications in the original or even abandoning it can happen later My starting samples were knit on 32 stitches, not enough to get a sense of or a good view of the horizontal repeat of 24 stitches. At first, I used the design version with no horizontal black lines in the download. The difference between the every needle rib at the bottom of the pieces and the slip stitch blister fabric is easily seen. Slip stitches are short and thin whether single or double bed. On the left, I used the tensions of 4/4, as for the particular yarn in past experiments. On the right, the switch was made to 4/2. The tighter ribber tension made the blisters more pronounced. The non selected needles on the main bed create the pockets. Because functions repeat for pairs of rows in this design, the first preselection row can happen from either side and cam buttons may be reversed with similar results as seen in top vs bottom below. Opposite part buttons are used as in option A or B.As I have explained in the past, I tend to leave the slide lever permanently in the center position. It becomes one less variable, forgetting to reset it can result in errors in gauge and more mishaps when knitting multiple pieces where gauge matters significantly or in reproducing previous work. The “striped” repeat produces essentially the same fabric. The knit carriage may be set to slip in both directions when using it since the row of all punched holes or black pixels will knit every stitch on every needle selected while in the previous samples the cam button set to knit in one direction performed that function regardless of any markings on the design repeat.  The ribber is set to knit in one direction, slip in the other. Reversing sides for cam button settings produces the same fabric  

To my mind, the best shapes for this sort of surface design are clearly geometric ones. My eye sees them as more easily identified on the surface of the resulting knit. Sticking with the original “flower” however, here it is after a bit of editing of just a few pixels followed by a larger swatchThe Stitchworld Pattern Book is another good source for predesigned repeats, many in units suitable for punchcards as well. I was attracted to the possible geometry in this particular patternThe repeat I chose is designated as suitable for the Garter Carriage. It is 24 stitches wide by 48 rows high, shown below as provided, charted in Gimp as .png for download, and tiled to help visualize how continuous repeats might line up. The image .png was downloaded with img2track to my 930, with a stretch factor of 1.0, retaining the original repeat sizeThe resulting knit is interesting on both its knit and the purl sides, clearly shows how the “image” is shortened in slip stitch techniques, elongation would be required to create more of the diamond shape Final decisions are often best made after a period of rest for both the knit and for our eyes. It is only in the actual knitting that the shapes can be finally evaluated, worked on further, or abandoned. One of my own best selling felted items for more than a decade was born from an accidental effect on a large swatch that nearly landed in the trashcan after it became something different than what I had planned or expected.

DBJ: more than 2 colors per row 2

I am taking a break from this topic for a bit. At some point will add at least one more swatch and perform another edit. My eyeballs and brain need to be looking at some single color knitting and no more than 2 color squares for a while 🙂

My first attempt to use a 3 color automatic separation was with img2track. There are 2 oddities for me using the program. One is that the default selector setting is for a single motif, perhaps on the assumption that the main use would primarily be for large scale, nonrepetitive images. The other is that even if working with 2-row color changes with each color in each design row knitting for 2 rows, the first preselection row must be made from the color changer side. This is a necessity in Japanese color separations for 2 color work where the first color knits for only one row on moving from the right side to the left, but if 2 colors with the same selection are required at the start, one row of the 2 appears to be technically eliminated as a result. I had expected to use 3 shades of grey, a pleasant surprise: the program can actually import a 3 color other than grays. The test was using the 11 stitch repeat A pleasant surprise: the program can actually import a 3 color other than greys image. Using Gimp, images worked in RGB can be reduced to indexed 3 colors for this purpose. If there are rows where there is no color represented, then as explained later in the post, the indexing should be to 4 colors, not 3 for the planned for import to work properly.The design is automatically flipped vertically, so it will appear as intended on the knit side of the fabric. Yarn colors may be placed in the color changer matching the order in the assigned color numbers to match the placements in the original image. The program automatically adjusts for the vertical stretch, which changes the aspect ratio of the shapes. On my 930 I received prompts on which color to change to prior to doing so, eliminating any confusion. With no such prompts generally one can tell which color was knit last because it will appear on top of the previously used one on the left of the knit. With a stretch factor of 1 selected in img2track, the image height was reduced by half. To achieve a look closer to the intended shape,  the repeat needs to be rendered twice as long. The stretch factor can be adjusted in the program itself to 2.0

In the past, I have preferred to elongate the design prior to importing with plans for download rather than to rely on memory for changing settings either in the download program or in the machine itself in future uses of the same design. The same yarns, tension, total number of carriage passes, and settings were used showing the difference in aspect ratio between single color per row knitting and the img2track built-in color separation. The width of both swatches is essentially identical.

Images may be loaded into the program without the cable being connected to the machine. Error messages do appear with download attempts if the cable is not properly in place. The machine also needs to be powered on before the program is launched if a download is planned. I am working in Mac OS Mojave 10.14.6, have no present desire to upgrade to Catalina.
Executing fabrics that will knit each color in each row only once for every 2 passes on the main bed: back to that original repeat Here it is used as drawn, note vertical stretch set at 2, will be cut in half by the software, getting the image back to the original height l0 X 3 = 30 rows required for all colors to knit in turn; there will be 60 carriage passes to complete one single repeat.The 930 will provide prompts for the next color to be selected by pushing the matching number button on the color changer, avoiding any confusion in terms of what should be picked up next. img2track will also flip the design horizontally automatically so the image will appear as originally drawn on the knit side. Images are loaded as single motifs, so the change in the selector needs to be made manually for an all-over pattern.

In order to have each color in each row knit only once: cast on with preferred method and color. Set up the machine so that the yarn colors are placed in the color shown in the image presented by the program to match your design. End with the machine on the left-hand side for the first preselection row.
COL: set both carriages to slip in both directions and all its needles in B position, set lili buttons if not already in use, pick up color 1
knit one row to the right
COR: knit to left, color 1 will knit for a single row
**COL: change color, STOP! Push back any needles on the top bed back to B position, as you knit to the right the ribber only will be knitting, knit one row to the right
COR: preselected needles will knit in the color last picked up on the way back to the color changer, knitting only one row in that color on the main bed as you return to the left**
repeat the last ** 2 steps throughout. One can get into a rhythm. A cast on comb, part of a garter bar, or any tool of adequate width can make it a quick process of pushing needles back to B when needed to
trust the software, not the selection expected by your eyes.
My swatch seemed to be growing in length at a faster rate than I remembered in the last exercise, here the results are shown side by side with the fabric executed previouslyObviously a success in terms of the single row for each color reducing elongation of the design shape.  While knitting occurs using the same yarns, at the same tensions, there is a clear difference in the length of each stitch on the main bed and their appearance. The reverse. Checking the ribber carriage I noticed on the left side it was set to knit only, not to slip: OOPS! N is king, so the ribber set as shown is knitting every other needle when moving to the right, but even with lili buttons in use it knits on every needle when moving back to the left. Every other needle on the ribber will then be knitting for 2 rows as a result. The more knitting on the ribber for each pair of rows, the longer the stitches on the opposite bed. The backing is an interesting variation (half) birdseye. The elongated stitches on the main bed show more of the backing in between their shapes, it is referred to as bleedthrough. In some instances, the result can make the knit surface resemble weaving and its appearance far less familiar in a surprising, pleasant way. Beauty is in the eye of the beholder.
Remember always to double-check all settings at the start of any process in case something was missed or magically moved, and keep notes.

I was asked on Facebook whether the technique shown here is the same as the 3 color slip (skip) stitch patterns in the Stitchworld pattern book, my response: some of the stitch world patters for 3 color slip are designed for or may be used on the double bed (often single bed as well). For instance, patterns 392 and 394. The original designs are rendered color separated. Numbers on the left suggest the order for color changes to achieve a look similar to that in the swatch photos. Assuming the pattern is not easily accessible because of its being built in your machine’s memory, it would have to be entered into a paint program manually to make it available for import and in turn for download. Note that the color-changing sequence may change over the course of knitting the image, so prompts or notes of some sort would be needed to keep it correct. Each color in each row knits twice after each color change. My goals in my blog posts so far have been to keep a constant color changing sequence with each color in each row of any personal design knitting only once. I did it first with my own color separation, then, in turn, used the 3 color separation feature in img2track to achieve my desired result. Here are 2 images from the Stitchworld section in question The images could be replicated as given in a paint program, using only one color for the squares, but “should be reduced to black and white”. Attempting to import an indexed 2 color image drawn in a color other than BW may result in strange results. That said, if glitched knits are the goal, the above could work just fine. Curiously, here is the same process, using a different color, and a successful import. Checking again, I had forgotten to save the image after indexing it from RGB mode to 2 colors. and a test with another color 
Drop stitch lace periodically comes up, I have written several posts on the technique, now considered the possibility of producing it in 3 colors. The resulting fabric tends to be long, thin, and in need of blocking. There is no way to avoid the striped ground. Passap knitters often refer to this type of knitting as summer fair isle. I adjusted the repeat widthNote to self: if you are determined to use a punchcard carriage on your electronic machine remember there is no KCII to cancel end needle selection!
In order to knit this fabric stitches must be cast on in whatever method you prefer, but prior to any patterning all stitches must be transferred down to the ribber, and the main bed needles are placed in working position but are empty. Because of the single row knit for the first 2 design rows of color one, the start is a bit finicky. Alternative start follows lower in post
COL: KC II, main bed set to slip <– –>, ribber stays on N throughout, no lili buttons. Knit one row with color 1 (ribber only)
COR: as you knit to return to the left, the color 1 preselected needles will knit, while the ones corresponding to color 2 will preselect
COL: carefully drop any stitches on needles with color 1 on them without disturbing the new needle selection for color 2
**COL: change color, knit to right
COR: drop the stitches knit in the new color, make certain all needles are empty and in B position, knit back to left and needles will be preselected for the next color**
Repeat the ** to**
Again resulting fabric is narrow and long, it may take a bit of squinting to recognize the design. A single repeat results in about 3.5 by 9 inches of knitting, a far cry from what might have resulted in a single row per color design row dbj virtually shown here in a tiled format

The question then comes up re dropping only one of the 3 colors. Using the manual selection described above, the knitting on the top bed would need to be canceled on every color, every row except for the single row in the chosen drop stitch color. To my mind, that is too much to keep track of for any length of time. It would be easier achieved with specific self-drawn color separations.
There is a lot of testing that can go into developing any fabric in unfamiliar techniques that may or may not meet our expectations or our “like”, it all contributes to learning regardless of whether the tests evolve into projects.

My last post on drop stitch lace in from single color to two: revisiting the techniques on brother machines

Reviewing what happens within the program one more time, highlighting significant items to verify before beginning to knit Getting that first row to knit twice instead of a single time if that matters in your technique or is your preference:
advance design row to last one in the sequence, in this case, 30
in the 930 when the pattern is loaded, using the down arrow key gets to the last row in the downloaded pattern more quickly

COL: set machine to preselect pattern, the next 2 passes would need to not knit, so both carriages are set to slip in both directions
knit one row to the right
COR: number 30 design row flashes
knit one more free pass to left, row 1 of color 1 will preselect as you knit
COL: number 1
design row flashes
check all settings,
main bed set to slip <– –>, ribber set to slip <– –> with lili buttons, and with an even number of needles in work for standard dbj pick up color 1 in yarn changer
the resulting knit design will be elongated
COL
: knit one row to the right.
As you knit the first row of color 1 design row 1 will knit, row 2 of color one design row 1 will preselect
COR: knit back to the left
as you knit back to left row 2 of color 1 design row 1 will knit, row 1 of color 2 design row 1 will preselect
COL: pick up color 2,
continue in pattern changing colors every 2 rows

In designing your own, small repeats can easily be rendered even in a simple paint program. Larger, more complex ones, may best be worked using layers and masking in a variety of programs ie. Photoshop or Gimp. It is possible to combine 2 color dbj and 3 color dbj in the same piece simply by using different color separations for each segment, but the look of the fabric in terms of the length of each stitch on the knit side may be quite different when moving from one segment to the next. Of course, the backing will change as well. Though the aspect ratio of the design changes in terms of height when one knits 2 rows for each color in each design row, it remains the easiest separation method. Adding the hand selection as described above so that the main bed knits in one direction only helps reduce some of the extra height, making the original image more recognizable. There is no option within img2track to perform the action automatically in terms of adding the necessary blank rows to replace some of the colored ones in the separation.

Passap knitters are not left out of this idea. Passap preselects pushers. On the E 6000 Tech 179 emulates the built-in KRC option in Japanese model machines. My guess was that technique 180 for 2 colors, perhaps 197 with both arrow keys on the back may work for 3 colors. TBD in my next spurt of knitting activity on it. That said, the console built-in designs may be used cross-brand. It is possible in Passap to layer repeats in order to add the third color to the mix. Here is one sample reworked for use on Brother and downloaded into img2track. If black and white repeats are already in your library, one may easily recycle them adding a third color. Here I did so with a repeat intended for a very different topic future post. The image was altered and tiled in Gimp for a repeat alignment test and is also shown imported into img2track for possible knittingWhat of images that are published in punchcard machine references? It is probably best to start with smaller repeats. That said, this is from a Deco pattern book.  Deco punchcards were 40 stitches wide, could be joined together in length as can those for the Japanese models The image of the separation on the above right has not been proofed for accuracy. If it were, the next step would be to elongate it X 2 for color changes every 2 rows. One method is to elongate the original in a paint or photo processing program. The width is fixed (40), the height is scaled X 2. The resulting BW indexed image may be imported, using a 1.0 stretch factor, it remains unchanged. When I tried to elongate the unstretched image in img2track by 2.0 my first try failed. It turned out the reason was I had saved the import without first indexing it to 2 colors. With that corrected, the result matched the one from scaling X 2 in height in the paint program
For years now I have been doing color separations which at first could be extremely slow, one pixel at a time. With increasing familiarity with Gimp and Mac Numbers over time, I have been able to decrease the speed to achieve them immensely. So here, with img2track I now have a program that can work with and separate multiple colors at a time (up to 6 in its pull-down menu option). Here I returned to my first separation in 3 colors for the now-familiar repeat A, elongated it in the paint program B and imported A into img2track choosing 2.0 stretch and 3 colors C. I can totally live with the fact the colors are not the same. The color changer can be set up with my chosen colors in any order I choose

In my first tests with charting a repeat missing any color in some rows, I had scaled the original image taken from a spreadsheet to the wrong size in Gimp, so operator error resulted in crazy results in img2track.Here the image is scaled properly for each color represented for a single row in height, and also scaled again for double-height for possible knitting in Gimp. The Gimp scaling failed to be accurate for me (second image from left) until I indexed the original to 4 colors as well instead of 3. The no color rows as we view them actually serve as a fourth color in the separations. Importing the proper size png into img2track for separation of 4 colors per row now gives results that make sense: note the daunting estimate for the total number of carriage passes for a single repeat height
If the ribber has knit on every needle by its return to the color changer and the machine is set to slip both ways with no needle selection on the main bed, the “no color” can be executed as an empty yarn holder in the color changer combined with no yarn in the feeder.  The rows involved should simply not knit on the top bed, with no dropping of any of its stitches since no needles will have been selected thus coming forward with the yarn in the hooks and traveling behind the latches and in turn, slipping off the needles as a carriage with no yarn pushes the needles with now empty hooks back to B position.

In testing concepts, I prefer to work initially with small repeats. Punchcard books can be an excellent source, but the Stitchworld books have the advantage of actually showing a single repeat for each design, so an 8 stitch repeat, for example, would be shown as such and it would not be up to the person using it shown in a 24 stitch card one to isolate it. I randomly chose pattern 394. I realize that if used from a built-in library of patterns in any machine model the prompts may be provided by the machine, but here I am looking at simply duplicating the pattern for import into img2track.

After duplicating the repeat and associated numbering using Numbers, these were some of my results. A pleasing surprise was that colors in the 2 color import need not be only black and white. That said, the pale green failed, the red did not, and the results from importing both the red/white and the black/white were identical. Another future time saver for me to keep in mind. 

If colors were assigned to each pair rows representing each color used, the white squares were read as an added color on import, and the only way to have those few blocks for the 4th color to show up in the visual representation in an imported repeat was to assign a 5 color separation, resulting in a scrambled pattern. Removing the few squares in color 4 will produce inaccurate separations for actual knitting of the given pattern whether imported to be rendered for 3 colors or 4. The black and white on the right is the “correct” match, leaving any prompts for use of shifting color changers to be tracked somehow by the knitter. Punchcard knitters may have the easiest time to knit variable color sequences since cards may be visually marked up with colored pencils matching needed change locations and taking into account your eyes are a number of rows above the row being read by the card reader. This number depends on the machine brand and model.

Some spreadsheets that may help with tracking row color changes or other regular actions on paper: 2018/04/tracking-rows-1.pdf

I have been asked about the position of the slide lever being fixed in my dbj illustrations. I have found the alternate positions can be wild cards, would rather make adjustments in carriage settings if needed rather than let the factory settings do some of the work for me. If the settings are accidentally in the wrong place as multiple pieces are knit, or in knitting ribber bands for garment pieces, the gauge is changed if the alternate setting is not adjusted and kept constant, and that may not be noticed until the piece of knitting in question is completed, needing a restart. With 15-20 machines active in each studio class and lab session, out of habit, I tried to reduce as many variables as possible.

Revisiting use of lace patterns Studio vs Brother machines

2011: There are several brand KMs still around and in use, most are no longer being manufactured. Questions often come up on how to use one KM brand pattern card on another. Card readers inside the machine are below eye level, so exterior number/other markings on cards or mylars reflect that, providing the knitter with a visual cue as to where they are in the repeat. If machines pre-select, the needle selection may not bear any relationship to the actual design row on the punched card or mylar as opposed to what one sees. In addition to this variable in lace one often has 2 carriages in use. It is possible to develop cards etc. from lace hand knitting graphs, but there is enough going on so a good place where to start experimenting is with pre-drawn ones. Lace preselection on any single row may have no obvious relationship to where the lace hole will ultimately end up.
Here are some random facts gathered from both sources and experience, they are applicable only if the knit carriage is set for plain knitting and no other function ie. slip or tuck is involved; plain knit rows do not advance the card reading mechanisms. In mixed structure fabrics, the rules change.
The Brother and Toyota lace cards can be used on studio punchcard machines as long as they are patterns which have 2 blank rows after each transfer sequence
Brother and Toyota have u shaped arrows to identify when to knit with the knit carriage, both brands read cards 7 rows down
The first row on Brother is transferred from right to left, while on Toyota it is transferred from left to right; Brother and Toyota cards are interchangeable provided the card is mirrored vertically (or a simple cheat: use carriages on opposite sides of usual)
For Studio knitting find the row number of the U shaped arrow and circle the 2nd and 3d row below that row that number to identify rows in which carriage is changed/set to knit
Brother knitting ends with 2 blank rows
Studio starts with 2 blank rows
on Studio begin brother card by locking card 4 rows before row 1, on row 3
Brother/Knitking lace carriage does not carry yarn, does not knit or trip the row counter; the stitches get transferred in the direction that the lace carriage is being pushed
Studio/Singer has a lace carriage available that transfers as it knits; on more complex laces one is sometimes instructed to set the carriage not to knit for a specified number of rows, the yarn may be removed, other adjustments are often required
though Studio and Brother lace cards are not directly interchangeable; aside from the numbering issue the transfer method is different, so a studio lace card working on a Brother or vice versa is a happy accident and likely to result in different fabric
Brother information is applicable to its new clone, Taitexma

2013 In this instance I am exploring the use of punchcards that are designed for transferring and knitting at the same time as seen in Studio simple lace in machines such as Brother, where the operation is the result of using 2 different carriages.

the Studio card used the resulting fabric The method: both carriages are used to select needles, use lace extension rails on both sides of the machine. Cancel end needle selection on knit carriage underside if possible, or push end needles back manually if needed to avoid their corresponding stitches being transferred throughout the piece. Set up for knitting the pattern as usual, punchcard row 3 (marked in pencil) becomes row 1 of the design when the above card is used in the Brother machine. The arrows always indicate the direction the lace carriage will move across the knit to make transfers in the direction of that same arrow.

  1. begin pattern knitting with COR, card locked, change knob on KC, no cam buttons in use. This will result in needle selection, but the fabric produced is in stocking stitch. The lace carriage is engaged o the opposite side, moves toward the knit carriage to make the transfers, as it travels across the bed the now empty needles will once again be in the B position.
    2. (lace carriage) travels back to right and is released off the machine (same needle selection appears, but those needles are now emptied of yarn)
    3. COL: KC moves left to right, knitting the single row, all needle hooks now are now full, new needle selection occurs
    4. LCOL: makes transfers toward the knit carriage, and then makes a second pass to return to the opposite side and is released.
    These 4 steps are repeated throughout the knitting, with the knit carriage knitting and selecting, the lace carriage following its selection to make the required transfers. Not every transfer row will match the direction of the arrows as marked on the studio punchcard.
    If there is no pattern needle selection with the KC pass on any row(s), continue to knit until there is needle selection, and begin the process using lace carriage to transfer toward the knit carriage from the opposite side and once again releasing it after its second pass.
    A caution: hesitation and reversal in movement of carriages in Brother machines advances the card in the reader, and results in mistakes in patterning; if errors are to be corrected or such movements need be made for any reason, it is worth locking the card, checking row numbers, remembering to release the card before continuing, and visually checking pattern after the next knit row.

2013: While working out yet another HK to MK lace pattern, I sorted out the following method for using Studio simple lace on the electronic KM. It is a method that does not work on the Brother punchcard to produce the same fabric, however; on punchcard machines as either carriage is moved to select from the opposite side of the bed, the card will not advance on the first pass, interrupting selection. I tried a swatch and got a very different lace design; depending on the starting pattern the results may be interesting (do not use elongation), but not the ones intended to match any original.
The knitting samples shown below were knit on a Brother 910. On electronic machines, as seen in previous posts on knitting with 2 carriages, the mylar (or otherwise programmed) repeat advances a row with each pass of the carriage, no matter on which side of the bed the pass originates. Dropped stitches are harder to repair in these fabrics than in patterns for multiple transfer lace (there knitting can be unraveled to the start of a sequence where 2 or more knit rows usually occur), so checking transfers, gate pegs, and adjusting stitch size and weights matter even more.

start knitting with KC (knit carriage) on left, Lace Carriage (LC) on Right program pattern double length
on the first row the LC selects, the next row it will transfer; LC always makes 2 passes first toward the KC, then away from it, even if those 2 rows in repeat have no needle selection. It is then removed from the bed to be returned to the bed on the opposite side after the knit row with KC that follows. In summary:
KC knits a single row to the opposite side
*LC is placed back onto machine opposite the KC to make 2 passes, is removed.
KC follows with a single knit row to the opposite side*.  * to* steps are repeated

April 2019 I attempted the same repeat on the 930 with img2track. I flipped the repeat horizontally and elongated it X 2 prior to knitting it. The arrows in the chart indicate the movement of the lace carriage, beginning with the first preselection row from the left I had issues with the proper needles being selected (proofed also in fair isle), but with random stitches not being transferred. A switch in lace carriages, needle retainer bar, yarn, did not eliminate the problem. I finally had to perform some of the transfers by hand. This swatch also shows the joy of missed dropped stitches in lace knitting, the yarn used is a thin acrylicDecember 7 2018: an interesting method using 2  electronic lace carriages found on youtube. The repeat used in the video is a variation of the one used in my sample above, programmed using img2track. The repeat is mirrored prior to knitting, there are extra knit rows to allow LCs to continue the pattern from alternate sides. The machine being used appears to be a 930. The requirement for mirroring of any pattern may depend on the model of electronic KM used to knit the lace and whether the download appears as drawn on the purl or the knit side of the piece  A comparison of my repeat using a single LC and the Knitlabo pattern expansion  including memo options for use with 2 lace carriages

This image shows the published inspiration used in the post (bottom), and a studio punchcard book version found at a later date for the same repeat. At this point in time, my image editing has evolved. Both repeats below were obtained by processing and scaling the original image in Gimp, for process please see posts 1, and 2  on 930 with img2track use # 1 variation key with the pattern repeat as shown, or flip horizontally prior to download. Ayab knitters pre latest software release: mirror repeat, tile repeat width across the number of stitches to match the number of needles to be used in your final piece. There will be no needle selection at the end of each sequence, signaling the need to release the LC, knit one row, and continue with LC brought to the opposite side. This is a very fussy knit. At several points, it is loops formed on previously empty needles that get transferred rather than full stitches. They love to get hung up on gate pegs. It took a significant amount of time to produce a proof of concept swatch. It is a lovely lace. Knitting it on a punchcard would give one the luxury of frequent pauses and markings to make for additional clues

Geometric shapes on ribber fabrics with tuck stitches 1

The previous post elicited a Facebook query as to whether it might be possible to create solid shapes within the field of brioche vertical stripes. The inspiration for the query was a hand-knit pattern published in Ravelry 

https://www.ravelry.com/patterns/library/pariss-brioche-scarf

Many terms are used in instruction manuals and published directions. In my notes I will refer to fabric with tucking on both beds as full fisherman rib, tucking on one bed only as half fisherman. These were my first attempts at exploring the inspiration idea, the fabric has inherent differences as it requires both slip and tuck stitch settings, so technically it is neither fisherman. Knitting happened on a random drop stitch day, which explains the patterning interruption errors.When attempting to knit isolated geometric areas on a field of frequently tucking stitches, automating the task when possible makes the process easier and faster. This was my first “diamond” pattern repeat, suitable for a punchcard machine as well. The design is illustrated on the left, converted to punched holes/black squares/pixels on the right  The knit carriage is set to tuck throughout. The programmed repeat will alternate the knit/ tuck functions across the bed based on black squares, punched holes, or pixels.  For full fisherman rib (top swatch) the ribber needs to tuck in one direction only, opposite to the action taking place on the main bed. A choice needs to be made on either of these 2 setting directions based on needle selection on the main bed and stays fixed throughout knitting. The ribber is set to knit on even-numbered design rows on the card, to tuck on odd. Row count numbers may be different than design row ones depending on row counter settings by the operator or built KM ones. Below are tuck settings for to the right on top, to the left on the bottom.

For half fisherman rib (middle swatch), the ribber is set to knit with every pass.

Note the half fisherman fabric is narrower than the full. Also, I am not used to my 930, overlooked that the machine was set for isolation, so its bottom diamond-shaped repeats are incomplete.

In the bottom swatch, I tried to produce a more distinct shape on tubular tuck created with only knit stitches on both sides of the fabric. Hand selection on the alternate beds on all tuck rows produced knit stitches in the desired area. A needle out of work made it easy for me to find a proper location on the needle bed.

Getting back to automating at least part of the process for such shapes: the repeat needs to be altered main bed will be knitting the black squares in the chart on the right on every row, tucking the white ones. When the ribber carriage is on the side appropriate for it to tuck the following row and no needles are selected in design segments on the top bed (odd-numbered design rows, ones with the majority of black squares, tuck may not be used in those locations because then the resulting stitches would be tucking on both beds with nothing holding the tuck loops down.

bring all needles between selected main bed needles up to hold on the ribber so that they will knit while the remaining needles tuck on the next pass of the carriages.

In my sampling, the ribber was set to tuck when moving from right to left. Below is the resulting swatch, shown on both sides. Part of one diamond shape is missing due to the fact I was concentrating on moving needles around and missed the change in selection on one side of the machine. Back to the original method used in the previous post where ribber settings are changed from knit to tuck <– –> every 2 rows along with color changes. I chose a design that would make it easy to identify the location of non-selected needles on the main bed in rows where the ribber will be set to tuck in both directions. The result is interesting, but the solid areas, narrower than the remaining knit, are in the opposite color to the dominant one on each side, the reverse of the inspiration fabric.
When needles are not selected on the main bed, interrupting the every needle selection.  Bring all needles on the ribber between selected needles up to hold on each of the 2 passes from left to right, and right to left. Stitches on those needles will knit rather than tuck resulting in this fabric The first swatch at the top of this post was achieved going a very different route. Two knit carriages were used to select and knit from opposite sides of the machine. Each carried one of the two colors. When working with the first color and coupled carriages the main bed is set to tuck <– –>, the ribber to knit <– –>. The second color is knit using the main bed knit carriage only, set to slip <– –>. A knit sinker plate may be altered and used so as to knit on the main bed only rows, adjustments to it are shown in the post: 2018/04/15/ribber-fabrics-produced-with-2-knit-carriages-selecting-needles/. The chart for my working repeat with a multiple of 4 rows in each pattern segment, color changes every 2 rows indicated on right trying to produce a diamond shape using this technique, my first repeat had arbitrarily placed pixels: the cam settings on the right of the swatch images correspond to those used in each swatch segment. Colors were changed every 2 rows throughout. The first 2 rows in the pattern were knit in a tuck setting, followed by 2 rows knit in slip. In segment B when no needles were selected on the top bed, all those needles were brought out to hold before knitting to the opposite side. Because every row is now knitting in the corresponding color changes the result is a striped pattern. Segment C is knit with both carriages set for 2 rows as in C1 alternating with knit carriage only set as in C2. At that point the color being carried knits only on the ribber, skipping non selected needles on the top bed, avoiding the striped result. A float is created between the beds in areas where no needles are selected that will be “hidden” as one returns to knitting in rib with 2 carriages. The arrow in the chart points to an area where two colors were picked up with the color swap rather than one. The resulting swatch samples

Analyzing the result in section C: the diamond is the same color on both sides, whereas the initial rectangular shape experiment reverses the colors. Reworking the diamond repeat in segments that are each a multiple of 4 rows:  Other considerations in DIY designs. The background repeat for this pattern is actually composed of units 2 wide by 4 rows high. If the pattern is intended to be repeated across a larger number of stitches on the machine bed than that in the chart, it is always worth tiling the image to pick up any errors (sometimes happy design features). Tiling in width readily shows an error tiling in height as well proofs row intersections as well tiling the corrected width repeat, now 42 stitches wide by 72 rows high sometimes tend not to keep immediate notes when I test ideas, which often comes with a price. I knit my first swatch using this repeat beginning the pattern with 2 rows of tuck, resulting in this fabric (and some randomly dropped stitches once more) with the same color diamond on both sides:  Beginning the pattern with 2 rows of slip stitch on the main bed only mirrors the swatch at the start of this post. Where no needles are selected on the main bed, with passes of the combined carriages, two rows of tuck will now be produced, resulting in the wider geometric shapes and the increased bleed through  The tuck loops created by the white in this instance have the elongated slip stitches in the alternate color (blue) partially covering them, creating the darker geometric shape in the top detail photo. The blue is thinner than the white, the effect will vary depending on yarn weight and tension used for the main bed yarn. One can begin to observe the change in width in areas with more stitches tucking.

If the aim is to have a tighter, more clearly defined diamond, after the swatches rested, the swatch that began in slip stitch setting appeared to “work” better to my eye, even with the single color geometric shape on both sides taken into account. Ultimately the choice is a personal one. The wider vertical stripes created in the white yarn in the slip combination fabric happen because of the 2- stitch wide repeat on the top bed as opposed to a single needle one in a true fisherman knit. Because of the slip setting the results will be narrower in width from it as well.

Ayab knitters will need to program any repeat across the width of the intended number of stitches, and use the single setting. Electronic knitters can enlarge the background pattern field easily, or create brickwork, extended repeats.

Arah-paint offers a free program that allows drawing repeats in different orientations with a few mouse clicks. Shifting this pattern must also be in pairs of pixels/black squares in this instance because of the 2X4 stitch background unit. The 21 (half) pixel shift shows an error in its continuity 22 stitch shift results in a “correct” all over repeat

Quite some time ago I experimented with shadow knits including in posts

2013: DIY design2017 crochet

It occurred to me the same design might work in a tuck rib version. The original repeat was 24 stitches wide, 28 rows high scaled to double length, 24 stitches wide by 56 rows high a tile test of new pattern Knit tests: the red yarn was very strong cotton, hard to knit smoothly, the blue encountered some stitches not being picked up on the main bed as well, but the concept may be worth exploring further. The main bed is set to tuck in both directions, the ribber to knit throughout. The red and white fabric is considerably wider because of the tension required to get the red cotton to knit. Better stitch formation results with the different yarn used for the second color

And lastly, a first quick adaptation of a design previously used for drop stitch lace, which requires some further clean up the yellow squares indicate loops tucking on both beds at the same time, the repeat on the far right is the one tested after eliminating those areas. It is 14 stitches wide by 80 rows high an “improved” version, the choice remaining as to whether to make all the blue shapes pointed at top and bottom or “flat” this is my repeat, tiled. It is 14 stitches by 84 rows The single 14X84 png
