The old pattern books for specific machine brands picture fabrics in many exciting textures.
This post includes information gleaned/ collated from several decades-old references and is shared as a possible starting point in exploring translations between brands.
I welcome being contacted if any knitters more experienced than I notice any errors.
The Duomatic locks compared with those of the E6 Arrow keys

Right –> reverses pusher positions as the lock moves from left to right
Both <–> reverse pusher positions every row
More on the lock settings, and planning follow-up swatches for some of the suggestions in the future, Traveling between Duomatic and E 6000 patterns is helped by tables showing the relationship between the Duomatic and E6 lock settings.
Duet Magazines #13 and #14
began a series attempting to match technique numbers in the Passap E 6000 to Duomatic techniques, which seemed to stop at that point. E6000 vs duo_ duet
The topic was popular at knitting machine seminars, and several other authors published their collections, offered at seminars such as Passap University and Passap Clubs. Many of the references in my collection are several decades old.
Color changes in text indicate changes in instructions, suitable for 3 and 4 colors, and with transfers from one bed to the other

Recipes for rib jacquard fabrics: E6000, Brother
Anyone reading my blog is likely familiar with my selection of topics based on the latest rabbit hole to attract my attention and elicit a leap on my part, a derailment of sorts.
Supplements to the manual were published when the model first became available. Duet often offered very valuable tables, ie an electronic pattern matching chars in #6, pp 21 and 22
I still own an E6000, but it has been used infrequently in the past few years.
When my iMac was replaced with a new one with an M1 chip I purchased a PC to use for knitting downloads that were not possible on the Mac.
At present, I am working on establishing downloading to the Passap from the PC using Wincrea, the Croucher cable, and a USB to a serial connector, and am considering exploring some knits in the spirit of how and why the stitch formations happen, still comparing the results to those using Brother knitting machines.
At one point, I taught advanced knitting workshops to textile students and immersed myself in gathering pertinent information before doing so.
Every one of my Passap manual pages is pretty much marked in a manner such as this. At the time, the added notes made perfect sense.
A couple of decades later, my scribbles require deciphering, and I find myself wishing for what might have been an expanded notebook with notes that would make better sense now.

Passap Duomatic and Deco pattern musings
My exposure to Duomatic knitting was limited to a few months in 1997 when I had the opportunity to travel to Cochabamba, Bolivia, to attempt to teach the native knitters in a cooperative to use patterning on their Duomatics and learned as many basics as I could.
Since then, any such personal learning has been unused and nearly completely forgotten.
I still own an E 6000.
Out of habit, in terms of Brother knitting, I still travel between patterning for punchcard machines and electronic ones and I have had a continued interest in interpreting pattern directions from manuals and pubs intended for other brands.
If the ultimate goal is DIY on any model, it is useful to first understand how published designs or built-in console patterns form the designs into knit images and textures.
Youtube offers many videos for those who prefer learning in that format, some are excellent and easily found.
I tend to knit like I cook, with lots of recipes in front of me, deciding what I want to use from any of them, and then “going for it” in terms of interpretation and execution. The process is made possible by the fact that many manuals and pattern books are now available for free online ie. for the Duomatic.
Some people offer items normally free on such a website for a fee on for-sale sites or their web pages. Before purchasing them, a quick search will reveal the free file resources.
The information here is very abridged, intended to introduce some of the specific machine concepts to knitters who may be new to the brand.
Some references for building a Passap pattern and instruction library for home study:
Passap stitch Pattern book #2 for Passap Duomatic and Passap 12 Its advice on maintaining neat edges:
The Duomatic 80 manual
Passap Duomatic 80 and Duomatic S Stitch Patterns
Some basics in adding automated patterning:
the Deco is an accessory composed of four separate parts that combine to help with automatic pattern selection on Passap model machines capable of accepting it.
The deco selector selects the pushers for the pattern and trips the card to rotate every 2 rows (Deco 2) or every 4 rows (Deco 4).
The card reader holds and advances the card-sensing feelers of the reader that indicate which pushers are to be selected and has windows that reveal the card row number.
The sensing feelers respond to perforations on the card.
The rack/ rail holds the reader and has markings to indicate the center of the needle bed. Patterning is in 40-stitch increments.
The cards transfer the designs to the selector, can be overlapped for continuous designs, and are assigned letters in alphabetical order to indicate what stitch type can be executed using them.
From the manual, not intended as full instructions, only as a beginning in comparing design differences and language used in the different models: Guide to settings for designs provided with the cards supplied with the accessory
A minimum of 36 rows are recommended for a continuous design.
The trip cam for the row counter is placed at the left edge of the knitting.
To begin patterning, a pusher is brought out of the rail and placed under each needle in use, the deco selector is set to 0, and make sure the red dot is showing.
Move the selector from left to right to preselect the pushers for the first design row, set the locks for the planned stitch type, press any arrow keys needed, and begin knitting according to published suggestions.
Clear end needles with each pass.
As each row is knit pushers for the next row of knitting are preselected, akin to Brother needle preselection.
Three rows of squares are punched at the top and bottom of each card for the overlap in a continuous design or for joining cards.
The width of the design repeats must number factors of 40 ie 2, 4, 8, 10, 20, and 40 vs those for Japanese models of 2, 4, 6, 8, 12, 24.
Where the card reader is placed on the slotted rack controls where the pattern occurs on the knit fabric.
Isolating motifs can be achieved by placing isolation pins from right to left in the slotted rack, five are supplied but even more may be used.
Double letters indicate double bed fabrics with lock settings that may not match on the front and back for stitch type or arrow-key selections.
From:
A 106-page resource, written by Bernadette A. Ernakovich, and available for download purchase is an excellent guide to exploring the qualities achieved by changing lock settings on the hand, feel, look, and shape on the original design, found in the simple triangle card #77 in the basic set

Long stitch Passap and Brother DBJ design using thick and thin yarns
In browsing through old photos I came across one of this swatch knit on the Passap eons ago, in a slightly textured unknown fiber, and a thin white one on a small cone with lost fiber markings. The find led me to attempt a similar knit using my 930.
The flower image # 1228, 20X20 doubled in height and width to 40X40
the brick repeat followed by its smallest unit, 20X40
60X60 half drop, followed by its smallest unit, 40X20
To knit the repeats as DBJ to reduce elongation, in the Passap, use Tech 179 intended for single bed fair isle but bring the back bed needles into work to match the Japanese built-in KRC separation along with birdseye backing.
The built-in double bed fair-isle techniques on the Passap use a default color separation where each color in each design row knits twice.
The console performs the separation, but to achieve the same result in Brother models, the manual color separation can be performed using Gimp in this instance.
A: the chosen file, 20X20B: scaled in length X2, to 20X40
C: color inverting every other row beginning with an all-white pixel row
D: scaling the file X2 in length to 20X80
choosing a black row start planned in the background color by color inverting the png
E: taking into consideration that the planned DBJ settings will elongate the design, the 20X80 file is scaled in width X2 to 40X80
2024:
Using color to alpha and opening a series of new files to achieve the same result: open the 20X40 image
a new file, using a row of white followed by one of an added color from the available palette, ie red in this is 20X2 PNG
copy it to clipboard and use it to fill a new 20X40 file, white color to alpha
copy and paste it on a new file matching the original
use color to alpha to render the red transparent, then color invert
paste the result on the original file
scale to double width and height to 40X80, change mode to indexed BW
Knitting the swatch:
The thin white yarn simply refused to be knitted on the 930 without breaking. The problem can sometimes be solved by adding a second thread, which in this case, is a 3,000-yard monofilament serger thread, both are hard to see and slippery.
The way the yarn is picked up and carried varies with the knitting machine models’ color changers.
When using the Brother double bed color changer, it is picked up and swapped out in the ribber arm, while in Passap models, the colors are threaded into individual feeding eyelets which are swapped out in any sequence needed in the front lock.
Some of the yarn-feeding issues in small or large cones can be solved by “putting a sock” on the cones, no matter their size. The manufacturer sometimes supplies the latter, but DIY versions can be segments of pantyhose, foam sleeves used to protect some of the exotic fruits in supermarkets, covers for flowers until they are used in arrangements, and at times simply a plastic bag.
My arrangement, with the threads on top of the machine table, and fed through the same side of the yarn mast. The first preselection row is from right to left
The ribber is set to knit in both directions throughout
The first and last needles are in work on the ribber
Colors are changed every two rows
The backing will be striped, with each color knitting for 2 rows, referred to as striper backing in many pubs.
Pattern knitting begins COL, set the knit carriage to slip in both directions
The proof of concept: The matching technique using the settings for knitting (N) on the back lock and slip (LX) on the front lock, for striper backing is 183:
knit on 30 stitches, but less than full repeat in height.
With some understanding of the pattern selection method for the front lock, different Technique numbers may be used for the same knit result simply by changing pusher arrangements and lock settings on either or even both beds.
This test was knit on 30 stitches and for 100 rows after changing the ground yarn, adjusting the tension, and programming Tech 180, but disregarding the pusher set up for the back bed, and setting the back lock to N The fabric is stable and reversible with interesting peek-through that reminded me of drop stitch lace.
The existing color separation for the single-flower may be drawn in half drop or brick repeats using ArahPaint
brick repeat, 40X160
half drop repeat, 80X80
Proof of concept swatch: the knit pattern area measures 14.5X11 inches, was worked on 80 stitches for 160 rows. The design repeat is 80X80 pixels. The fabric is reversible and lies flat.
Tuck stitch meets knit-weaving
This video was recently shared on Facebook. The sample in the video was knit on a Studio/Silver Reed brand knitting machine and prompted the question about the possibility of knitting the same pattern on a Brother machine.
Some techniques require infinite patience.
A summary of observations made looking at the video:
1: the machine tucks for two rows
2: the card is set to elongation for weaving rows, where the pattern selection continues, but the carriage is set to knit the background for woven rows
3: the carriage is set to tuck once more to complete what are 8 or more rows of pattern
4: start the process again by knitting four rows of tuck followed by 2 rows of knit weaving until the top of the piece is reached, ending with two rows of tuck before binding off.
Studio machines select as they knit each row, while Brother machines preselect each row as knitting continues after the initial preselection row.
There cam buttons switch from tuck to knit, and the card rotation settings are changed frequently from single to double length on the repeat segment as given.
To mimic the video, this is a chart for the adjusted repeat planning to knit a swatch on an electronic model using 2 knit carriages selecting needles with the pattern advancing one design row for each pass of the carriage.
The cam button variations: the yellow cells mark tuck stitch rows. The red cells mark the knit-woven rows, where the carriage is set to knit with continued pattern selection, and a weaving yarn is brought into play for 2 rows.
The knit carriage is then set to tuck once more, and the process repeats. Punchcard users working with a single knit carriage can punch all black cells in the width given in the chart, and twice its height for 48 rows, eliminating the need for elongation shown in the video.
Using 2 knit carriages can eliminate cam button changes from tuck to knit and back.
When using any pair of carriages to select needles, each carriage must be disengaged from the belt while the other carriage is being used to avoid breaking it, so extension rails are required.
I began with the sample knit on 30 stitches on my 930.
The carriage set to tuck operates from the left, the knit-weaving one from the right, with the first preselection row made from right to left.
The 30-stitch test includes a one-stitch knit border vertically on either side. The main background yarn used for tuck rows color is a 3/9 wool, and the knit weaving carriage is threaded with a slightly thinner, darker yarn of unknown thickness. The weaving yarn is a worsted-weight wool.
Changing the ground yarn to the same yellow 2/20 in both carriages, the pattern was first knit in tuck stitch alone, possible for 6 rows because of the yarn thickness,
and then using the 2 carriages knit weaving at the same intervals resumed.
A pair of some of the previous posts on using 2 knit carriages to select needles on Brother machines

Knitting in pattern with 2 carriages, Brother punchcard KMs 1
The Punchcard used in the video Brother punchcard machines repeat the preselection of needles on the first pass with the carriage from the opposite side to advantage in reproducing the swatch. The two 892E carriages
If a second punchcard carriage is not available but an electronic one is, the model year may affect the fit, but an electronic carriage can be used on a punchcard machine to advance the card and select needles.
The first row on the Studio card is locked on row 3 to preselect the first tuck row on the Brother from right to left
Rows 1-2: COL, set the carriage to tuck in both directions, make 2 carriage passes, ending COL with the carriage positioned on the extension rail, clearing the belt
Rows 3-4: COR, begin with the second carriage set to KC and outside the set line, and do not push in any cam buttons. Prepare your weaving yarn. Knit to the left, the card does not advance.
COL: weave the second row, move the carriage back ending COR on the extension rail, clearing the belt
Rows 5-8: COL, the card does not advance on the first pass to the right, knit 4 rows of tuck stitches, ending COL on the extension rail, clearing the belt
Rows 9-10: COR, repeat 2 rows of knit weaving
reminder: any hesitation with movement back and forth of either carriage once it is on the knit bed and selecting, will advance the card one design row
Repeat Rows # 5-10 twice to complete each full repeat segment
Choose an ending pattern segment and bind-off.

Gimp 4, pattern fill, dithered portraits, and more.
The latest version of Gimp for Mac includes many small changes which come with no announcements and take a bit of sorting out to recognize or problem-solve.
There are good collections of Youtube videos intended for use on much larger files, with fewer color restrictions than images used for knitting.
A dock is a container that holds a collection of dialogs.
I work in single-window mode and had an issue a few times recently with the tool dock and dialogue disappearing from the left.
The method that worked for me:
on a Mac, select the link to the Preferences/Settings window found in the GIMP application menu, next to the Apple menu. Scroll down in the left pane until you see the Windows Management entry. Click on it to open the relevant settings pane. Look for the giant button labeled Reset Saved Window Positions to Default Values, seen on the bottom right.
Click on it, and GIMP will pop up a small notification box letting you know that the save will go into effect the next time GIMP loads.
Click OK there, and click OK again in the main Settings window.
Close GIMP and reload it, and familiar settings should be back.
To prevent a reoccurrence of the issue, it is possible to lock the associated tab, permanently fixing the dialogue. To do so, click on the small shape next to the Tool Options Menu text on the top right, then select Lock Tab to Dock. Tool icons are also changed at times, leading to puzzlement when steps used in the past do not work. An example,
The layers menu no longer offers the difference mode used previously in custom color separations.
From the manual: “If you need to stay compatible with older GIMP versions or you need to use the legacy layer modes for other reasons, look for the icon to the right of the layer modes selection.
This drop-down menu will let you choose between Default and Legacy. If you choose the latter, the layer modes list will only show the legacy layer modes and all modes will have “(legacy)” behind their name (the selected mode will use the short version (l). ”
To make the dialog available: click on Legacy to switch mode selections.
My posts are at times generated in response to questions I have received through forums or direct contact via my blog, but most often by my exploring whatever rabbit hole attracts my attention for a period of time before leaping into the next.
A quick way to fill with a design/ drawing in repeat is to choose and open an image, ie this rose, indexed B/W 28X30 pixels Magnify ie to 800X, go to Edit, and Copy Visible to save it to the clipboard as long as the program is open
Choose File, New, in size that is a multiple of the original ie 84X90.
Select the brush tool In the Windows menu choose Dockable Dialogues and select Symmetry Painting, then Tiling.
After entering the desired values, as you move onto the canvas, a brush icon and crosshair will appear, along with a square bordered with a dotted edge representing the clipboard brush in full size, place it touching the left upper corner for a straightforward tiled repeat, an alternative to the familiar method using Filter, Map, Tile. Undo and repeat if needed.
For a brick repeat
For easy and quick drawing in any repeat configuration including random, I recommend using ArahPaint.
For other tiling repeats, I have found Gimp offset limiting, offering this as an alternative method for, in this case, a half-drop design.
Work in matching magnifications as steps are advanced.
Begin with the rose, use filter, map, and tile it to twice its height, 28X60 Open a new file, twice its height and width, 56X60 pixels.
Using rulers as guides for the half drop, place a center vertical guide at 28, horizontal guides at 15, and 45 click on the 28X60 selection at the top of the work window, copy and paste it on the file marked with guides first on the left side, click on the rectangle tool to fix the layer
paste it again on the right, placing a full rose in the center square outlined in the column,
paste again and move the selection above or below to fill in the empty third of the column
select the rectangle tool again to fix the layer, save the 56X60 file, filter, map, and tile again to test the alignment ie here, 168X80
the icons selections at the top of the work windows change as steps are completed
A visual summary of the 28X60 image placements
A pattern is a small image that fills areas by placing copies side by side, while a brush is used for painting.
In drafting A collection of geometric design blocks built with squares, rectangles, and lines and considering optical design development, Gimp fill with pattern gained my focus once more.
Pattern fill was discussed in Gimp update for Mac 2
In developing pattern-fill libraries, and saving them, using larger pixel group pngs rather than the smallest repeat needed makes identifying them easier.
These suggestions are for drafts on 8X8 pixel grids.
They may be used to pattern fill from the clipboard while the program is open, or exported as .pat files, adding them to a “my pattern” folder through program settings, where they will be available after Gimp is quit and reopened.
Always tile/draw-in-repeats to check alignment prior to saving.
Color-reversed versions are also useful.
Once the basics are tested, one may begin to move towards shapes and more complex repeats, particularly if using electronic machines. A library of circles, some in dimension used in developing truchet tiles, drawn using the built-in Gimp circle brush, from 5 to 24 and 28 pixels in size.
Developing dot designs merit a separate thread as well as more on symmetry painting.
The patterns may be saved as color or black-and-white files.
Passap users should know even though they may see this icon from some old company-shared files along with their own .cut ones, they are not compatible with Gimp software or any other outside the DAK universe that I know of, where they were an earlier format later replaced by the stp format.
There are always many ways to approach DIY, staggered lines of equal size with alternate color starting points can fill in spaces between each other.
Gimp has offset and symmetry drawing functions.
As a long-time repeat builder, if working in Gimp alone, I prefer working with multiple images open to using layers, and visually making the drops or shifts in the repeats manually by copying and pasting on progressive-size canvases.
Starting out with colored squares in RGB mode allows for filling in each color with multiple different BW patterns, for these samples I am using only 2 linear pattern fills, beginning with a 40X40 design tiled X5
in brick repeat
and in half drop
Introducing other shapes, 16X16
brick configuration, 32X32
half drop, 32X16
Keeping that black outline, but still rendered in B/W
Eliminating the outline, retaining a quarter circle, 16X16
Using mirroring, and cropping the repeat using several canvases, eliminating double lines in the process, 30X30.
The maximum size in width for large items in a single piece is generally between 180 and 200 stitches on 5 mm and 4.5 mm respectively.
Gimp comes with many built-in assorted patterns which can serve as a starting point. Here a 160X160 canvas is filled with a Gimp pattern, planning a 20 stitch border on all sides. Convert image mode to greyscale,
using Colors/Curves adjust values to an input of 47, and an output of 203,
and if planning to knit the piece in only 2 colors, convert the result once more to indexed B/W mode
To add any desired border, open a new file, in this case, 200 by 200, working in RGB mode, and fill it with any color other than black.
Copy and paste the image above onto it, it will be automatically centered Choosing another built-in pattern, the red border is pattern filled
To eliminate the yellow, use fuzzy select by color, and check that the bucket fill tool is set to fill with the background or foreground color again.
Press the shift key, and replace the yellow with white.
Convert mode to indexed B/W once more, and export as png.
If desired, using a grid view and pencil tool, additional black borders can be added.
The shift command keys on the Mac used in conjunction with the pencil tool help render straight pencil lines. Any of the larger files developed as tiled designs can be cropped to different dimensions depending on preference and end-use.
Decades ago, before software design aids, there was a knitting challenge circling around to include hidden language or undesirable language in a not necessarily easy-to-read format in knitting, beginning with hand-scripted text, which was then mirrored in width and height.
This was my version of DBJ vertical design, with the photo rotated and repeated to visualize what the appearance might be on a larger piece.
There are some really interesting examples of hiding messages in textiles throughout history and even books written on the topic, it is referred to as steganography, which means hidden writing.
When I was teaching there were often as many as 15-20 students knitting in the studio at the same time, and I felt a need for an expletive outside the less civilized 4 letter word that came to mind when multiple emergency yell shouting my name for help occurred at a single time.
Hints on using text: Gimp to create text for knitting
This image, rendered in Gimp with superimposed text and filled with patterns in both the text and in the background illustrates my answer to that problem. I have often seen illustrations of artworks for sale online using portraits with superimposed all-over patterns.
This concept for a possible knit began with an AI-generated foursome using Midjourney My chosen image, originally 700X700, with image mode changed from RGB to greyscale, indexed to 3 colors, scaled and trimmed to 181X183
selecting a random brush for superimposed pattern, 30X40
file, new, exact dimensions as portrait, white ground, 181X183, fill with pattern,
layer, transparency, color white to alpha,
copy and paste on portrait file, fix layer, save .png
Image ready for download using img2track
For use on a 930, the design is broken down into multiple tracks by the software, each to be downloaded in sequence as a new pattern.
Placing the portrait with white color to alpha on top of the BW pattern filled ground produces a slightly different result
The same repeat, with a few pixel changes
Using a different punchcard pattern repeat
with a different pattern fill, the portrait becomes more hidden
A video on achieving a similar effect using Arahpaint
If the goal is only to change the background, there are several options for that as well.
One way to remove a background containing varied shapes, and return to an often-used of my old friend Rocco,
the file, 150X154, add an Alpha Channel
The Free Selection tool, or Lasso, allows for creating a selection by using a pointer.
Since GIMP-2.10.12, selection modes now, in 2.10.34, work differently.
Marching ants/dots come with a continuous line, meaning that the selection is not validated yet and that you can still change the selection shape (the mouse pointer comes with the Move icon) but keyboard commands may no longer work. When satisfied with the changes hit enter/ return key on Mac to validate the selection. Enlarge the image to make following and marking its outline easier.
Freehand selection can be made in small segments at a time connecting short lines, or long, continuous strokes.
First, create a starting point by clicking on your image.
A yellow dot will appear. As you move along the edge of the image, the colored dot reappears every time you stop, with the previous locations turning into empty circles.
When it is reached, if you click on the endpoint, it turns filled and is accompanied by a moving cross. Use the return key to pause if needed.
Pressing and releasing the mouse pointer allows you to mix free-hand segments and polygonal segments.
If you click on the endpoint, dragging alters the shape.
When the endpoint is on top of the starting point, click to close the selection.
Double-clicking on the endpoint closes the selection with a straight line.
You can go outside the edge of the image display and come back in if you want to.
Escape cancels all continuous selection segments.
When the lasso selection is completed there will be visible dotted lines around the selection Color invert the result
Open a new, white canvas of the same size and magnification, and copy and paste the color inverted one on it
Use color invert once more, Rocco is now on a black ground
Using the result in online dithering programs provides a different result than when dithering the full greyscale image. This result is from using https://29a.ch/ditherlicious/
If the result is an instant favorite, and the goal is to fill the ground with a pattern, use the lasso tool again to eliminate the black more carefully than I did, repeat the steps to color invert, copy and paste on red,
Color invert once more,
Fill the background with a chosen pattern, convert image mode to indexed B/W, and export the resulting file
If the image is to be knit using 3 (or more) colors per row, this is one of the myriad possible results using my favorite dithering option, https://app.dithermark.com.
Returning to the greyscale image on the black ground, the latter can be bucket filled directly with any chosen pattern
To superimpose a pattern on the whole image, fill a white canvas in the same dimensions with the pattern
use Layer, transparency, color white to alpha
Copy and paste the result on the original
Full greyscale is not knittable.
What about using the AI portrait in B/W or 3-4 color knitting?
172X172ditherlicious 2-color,
and dithermark using the built-in pattern selector for 4-color.
The image will be elongated in actual knitting, this window from img2track on the left is set for 4 colors. Changing selection to 2 colors and opening the same image, it is converted to B/W

Visualizing knit cables in color 2_ using Numbers and Gimp
Hand knitting patterns are usually depicted with the knit side facing.
If crossings are intended to match them exactly when working on knitting machines, they are made on the purl side, and their direction needs to be mirrored.
The blue dots illustrate hand-knit symbols, and the pink dots the machine-knit companions I was recently contacted about the possibility of reproducing the swatch on the far right. The image on the left is an actual knit, first tested with cable crossings mirroring each other along vertical columns.
The inspiration swatch was likely knit on the bulky, twisted every 4 rows, mine on a 4.5 mm machine, twisted every 5 rows.
It is possible to crop, copy, and paste initial photos, as in the center image, to visualize how the process may be altered prior to spending time creating new charts or any actual knitting. Building charts in a spreadsheet:
begin with creating and saving custom shapes, which can be made editable, and outlined if preferred (magenta) to further define the stitch brought forward, with the other moved behind it (blue).
Symbols used:
1. black cells/ knit stitches
2. white cells/ needles out of work, creating ladder spaces and non-selected needle areas where stitches are to be moved in the direction of superimposed arrows
3. red arrows/ stitches that are lifted off the needle bed, brought to the front on the purl side. The stitch on the adjacent black cell/selected needles is removed, travels behind it, and replaces it. The held stitch is then placed on the now-empty needle. Both stitches are brought out to hold/E position to knit properly on the next carriage pass.
The plan is to use the slip-stitch setting in both directions.
Since there are needles not in use, the end needle selection needs to be canceled.
Proper needle placement is required for patterning accuracy.
One option for achieving it is by air knitting the first row of the design, another is to program the width of the planned knit in electronic machines, establishing pairings, and using the single motif setting with no guesswork.
A chain cast-on can be performed, followed by dropping chains in ladder locations and taking those needles out of work to A position.
Even weight is useful if crossings are to begin after only 4 rows of knitting.
Each repeat is 8 stitches wide, punchcard users repeat it X3 in width, and in the charted height X3. Proofs of concept: 30X20 electronic repeat for vertically mirrored transfers,
and the alternating twisted arrangement
The work on the machine
In the resulting swatches, patterning errors such as the marked one become difficult to repair after the fact as stitches grow in size and ladders nearly disappear
Both swatches measure less than 2.5 inches in width, another reason to explore the results on bulky models if they are to be used in garments.
If planned as panels combined with stocking stitch, careful planning is due to overall gauge differences and those in row counts when seaming and joining.
Blistered dbj 3
Names referring to the same knit fabric can vary between machine manuals for specific models and brands or references in books, magazines, and articles depending on the dates they were published.
My earlier share on the topic:
Blistered stitches dbj 1
Blistered DBJ 2 and technique variations on a single repeat, introduced some of the concepts involved.
Beginning with any random published repeat can offer the start of exploring a range of fabrics. This was a Pinterest punchcard share, markings indicate it was intended for Brother machines Methods for obtaining color separations for specific knits have been discussed in other posts.
Brother models can use the cam buttons to perform a function in one direction only, ie by using only one tuck or slip button, the machine will knit when the carriage reverses movement to the opposite side.
Developing specific color separations makes the files usable on other machine brands and models, makes it easier to return to specific rows in error corrections, and is my personal preference in test swatching and complete pieces.
Drawing the initial design in repeat provides a visualization of the resulting secondary shapes and the number of needles required for tiled variations in finished pieces based on gauge.
The first design is intended for use in every needle rib, with the knit carriage knitting in one direction, and using slip or even tuck in the opposite direction.
The 24X32 design extracted from the inspiration punchcard A: the rendering scaling the design twice in length
B: making the choice to color invert it in planning slipped stitches on the larger number of white pixels
C: superimposing black lines on every other row beginning with row 2 A quick review of the steps involved in working with Gimp:
begin with magnification for easy viewing, ie. 800X, view grid if preferred
the starting brush can be as small as this 2-pixel select it and save it to the clipboard by choosing copy visible, making it available to bucket fill images, or export the same design as a .pat file and save it in the appropriate settings folder for future use.
A: the original design repeat rendered in black and white
B: layer, transparency, color white to alpha
C: file, new, white ground, matching size, filled with a pattern of pairs of horizontal all-white pixel rows beginning with white on row one, followed by all-black pixel rows on row 2
D: copy B and paste it on C, and export the file as png The chosen repeat may not be color reversed after programming it using the machine’s built-in electronic functions.
White pixels slip, stitches on the main bed in non-selected areas would not knit off for extended periods ie where red marks occur, and noticeable problems would develop quickly Beginning proofs of concept for this version, 24X64
knit on 60 stitches using it drawn in repeat X3, 72X64, and programmed as a single motif
The result is a very subtle contrast lacey knit
The yarn thickness and color were changed. The pattern begins using the slip setting and transitions to tuck, also in only one direction. Because the ribber is knitting every stitch between stitches on the top bed holding side-by-side loops down, tucking on multiple side-by-side needles can be performed, producing a wider, stretchy knit that also lies flat.
True blisters/pintucks generally knit rows on the top bed alone forming pockets that are eventually sealed by all knit rows.
Slip stitch settings are used.
The design is at first lengthened X5, then every 5th row is filled with black pixels or punched holes.
A begins in smaller groups of gathers, testing for any errors or problems, while B allows for deeper folds. A:
the mark shows the stitches on the top bed begin to slip far too many rows
due to using the color reverse option in the 930 before continuing to knit. With a switch to the blue yarn, all-knit spaces between the pockets now begin to appear gathered. Slip stitch results in narrower knits, noticeable in the ruffled effects on every needle rib above the cast ons
B:
the extra row of slipped stitches result in a far more textured knit

A collection of geometric design blocks built with squares, rectangles, and lines
I have grown fond of playing with ArahPaint’s functions: guess weave from grid, and drawing in repeat, and am constantly amused by the speed with which most design repeats and color separations can now be drafted when compared to the very first efforts in the days of anyone trying to use Excel spreadsheets to accomplish the same tasks.
Drafts designed for handweaving provide endless inspiration for knit design.
In conjunction with ArahPaint, Gimp remains a frequent go-to as well, along with Numbers for Mac for when spreadsheet tables meet charting or design needs.
The programs are free, there is no need to purchase expensive design programs in order to develop DIY motifs.
Developing tiled repeats suitable for multiple stitch types, including tuck , offered some repeats that began with geometric blocks built with squares, rectangles, and lines, some of which are suitable for punchcard knitting.
Many are included here again to serve as a cumulative collection of possible springboards for use as is or for developing more personal variations.

Passap to Brother 6, exploring a possible tuck stitch design
This post has been prompted by a recent Ravelry query with respect to having had disappointing results when attempting to knit # 1301 from the Passap Pattern Book as a double-bed fantasy fair isle using a Brother model machine. Machine knitters using Japanese model machines are familiar with some tuck rules ie. white pixels/ unpunched squares that form tuck loops, should have a black pixel/ punched hole on each side of them and not occur vertically for more than 4 rows in order for stitches to knit off and form properly.
Tuck punchcards illustrated in Brother Volume #5 on pp 218 and 219 include a few exceptions to those rules such as #786 Looking at the reference design in the Passap Pattern book, it is used as a background motif only, not as a tuck one, and rotated using console commands.
When uncertain as to whether a design repeat is appropriate for a specific stitch type, begin with a limited-size swatch, a thin and familiar yarn, knit slowly, and listen to the sounds the machine produces, which can be early warnings of potential problems.
The Passap motif issues in terms of tuck knitting analyzed on the first look: there are pairs of blank cells side by side, repeating vertically, and combined throughout The first test is knit in acetate of unknown thickness, the guess is around 2/18. The 40-stitch swatch measures 6 inches in width, with transitions from and back to stocking stitch horizontal borders, and with the body knit on the single bed with the carriage cams set for tucking in both directions.
The unaltered repeat may be used double bed, resulting in 8 inches in width, with lots of stretch, and the potential to increase the measurement even more with blocking.
A: transitioning from stocking stitch to every needle rib without added steps will form eyelets
the knit carriage is then set to tuck in both directions, and the ribber carriage is set to knit in both
B: a return to every needle rib before scrapping off The chart on the left illustrates possible cam variations for knit and ribber beds using tuck settings in Brother machines.
Color separation is required to knit the design using two colors.
In the Passap electronic models, a technique number is entered and the appropriate color separation is performed by the console.
Many results as in this case, rely on each color in each design row being knit twice.
In Brother knitting, other methods need to be used in order to obtain the necessary separation.
The fabric though technically knit as dbj, will begin with the first preselection row from right to left toward the color changer as opposed to from left to right when the built-in electronic KRC separation is used.
Punchcard users can produce the same fabrics if 24 stitch width constraints are met.
The png for the repeat on the right is shared below, and tested using the cam settings 4:
The results using other cam settings can be mixed, and generally far more successful using designs with larger shapes forming design and ground.
Using tubular tuck, 2 the knit results become muddied, as seen at the top of this test

A different way to bend rules is to use multiple heights of row repeats within a single design, such as in this densely 24X20 tuck stitch design Drawn-in-repeat to 120X120 pixels
The design would need to be color reversed for use in electronic tuck knitting
Punchcard users must punch all the black cells
Using thin yarn is best with lots of evenly distributed weight, watch for loops getting hung up on gate pegs
Eliminating one row of blank squares where there are 5 in a row, reduces the repeat to 24X16
The result produces a similar texture. In this test swatch the number of stitches used was planned to attain similar side edges, and end needle selection was canceled
