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 placeholder 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, and 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 makes 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 with the transfer grid in a color, rows are hidden as above, and 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 the 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 a series of two passes at first, then followed by four, repeating the double sequence throughout. The mylar, card, or computer image, does not reflect the passes made by the knit carriage KC. The latter is set to knit, does not engage the belt, and 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 and 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 and preselects for transfers to the right
7. LC moves to the right, transfers to the right, no preselection
8. LC returns to the left, no transfers or preselection, stays there
9. KC moves to the left, and the pattern remains on the same row
10. KC moves to the right, and 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. 
2024:
The above is listed as a fine lace pattern. Most such patterns can be executed as standard transfer lace as well.
The addition of the ArahPaint guess weave from grid tool makes the process of converting charts such as the above easier and quicker.
The final BW chart 
and the associated 60X74 png. Depending on the machine model, the file may need to be mirrored horizontally before any knitting. 
in repeat 
The original image had markings for mylar that inform the frequency of knit carriage passes, which extend above the start and end of mylar markings to allow for the fact that the first design row is scanned below the row visible to the knitter on the exterior of the machine. 
When the png repeat is loaded into machine memory, reading begins on row 1. The knit row single pixel markings on the original can still serve as guides as to how many passes of the LC are followed by 2 knit carriage passes 
The column on the left indicates the number of LC passes before two knit carriage ones, the column on the right reflects the corresponding design rows. 
The image from the publication, with the color modified for clarity 
My sample was knit on a 930, hence mirrored horizontally, on 60 just stitches.
The yarn is a softly spun rayon with a tendency to split, and at the end of the second full repeat several stitches dropped, accounting for the length of the swatch;-) 
The second volume 
is also available as a free download, and in addition, mylars are as well.
The latter makes for clearer stitch and row counts and easier file conversions.

Double bed embossed patterns
Some of the previous blog posts containing applicable samples:
Ribber fabrics with stitch transfers between beds 1
Slip stitch patterns with hand transferred stitches, double bed
Brother shadow lace, rib transfer carriage 
Combining knit carriage needle selection with racking 
Racked patterns 5: Passap/Brother 2
directions and samples from manuals including racking on tuck stitch and other ground variations, this on a tucked ground, in a thin yarn 
Embossed, raised textures are familiar in single bed work using stitch structures such as tuck, slip, weaving, gathered and ruched hand techniques, and in double bed as pile, blister, lace, and ripple patterns.
When embossing is done double bed, the background fabric is knitted in purl stitches on one bed, and the raised design or panel in knit stitches on the other. The first method produces double knit patterns where all needles are working on the back bed, coupled with selected needles for the pattern on the opposite be. The raised, embossed portion is a double knit, showing relief on a purl ground. The second method is to use knit/ purl combinations, easiest to execute with a G carriage.
The striped ground occurs in areas where there are no needles in work and selected for patterning on the main bed. A cabled pattern to try: color changes in these instances are every 2 rows.
Because there are needles completely out of work on the main bed along with pattern selection, this is an instance where end needle selection must be canceled.
The first preselection row is from right to left toward the color changer.
Any transfers or stitch manipulations between or on either bed are made before the first pass to the right with the next color.
The knit carriage is set to slip both ways on the first pass in pattern from the left and stays there, the ribber is set to knit in both directions throughout. Depending on the yarn and the pattern distribution the all striped areas will be longer than those gathered by slipped rows. As usual, begin with a plan. After the first preselection row, transfers are made down to the ribber as indicated at the top of the chart. Cable transfers are made after every 14 knit rows, with stitches crossed on rows 15 and 31. After the cable cables are twisted, the stitches in the color that is going to knit in the next pass are brought out to E so they will knit in that color before the pass to the right, and again before the pass to the left, rows 16 and 32, Y.
If the intent is to have solid vertical columns of color, those areas as in column marked A, need to be adjusted for using alternating colors as well. Using the repeat on the left of the chart 
After the first preselection row to left, transfers are made down to the ribber, stitches that will compose cables are selected in the pattern,
colors are changed after return to the left, and every 2 rows, stitches in the color that does not knit become elongated. 
Because column A was not color separated for alternating colors, each color in the corresponding needles will knit with every two carriage passes, and the result will be a striped vertical column 
Cable twists should be planned to retain the correct movent, can alternate each time or repeat in series, charts for location and direction of twists are helpful to avoid errors. The solid vertical columns here are planned in only one color, could be programmed to alternate as well. The repeat used in my swatch includes a solid column on each side of the finished piece, the color swap in the twist at the top can be an unplanned error or serve as a deliberate design change
Analyzing the stitch structures involved for planning 2 color DIY:
two-color ribs on a striped ground require cards or electronic repeats that select each color alternately. Fabric where the backing on the ribber or back bed in machines such as Passap knits all stitches every row is often referred to as half or full Milano. The backing may be also be knit using slip/ tuck settings.
Working in a single color, in half Milano and every needle rib course is followed by a plain knit row on the opposite bed, it is a 2-row repeat. In full Milano fabric, a row of every needle rib is followed by a plain knit row on one side of the fabric, and then by a plain knit course on the other. The repeat is three rows high. On every third row, the ribber carriage must be set to slip for one row, in the direction in which the carriage will be moving, prior to knitting a row with every needle preselection on the top bed. The setting is changed back to knit for 2 rows when the carriages reach the opposite side. The required cam change will happen on alternate sides. 
Both sides of the fabric have small stitches alternating with longer ones formed by slipped rows. half Milano 
full Milano
Often an all slip setting is used on the top or front bed, the result has less elasticity than a full needle rib, and the knit will have a tendency to curl toward the side which shows fewer knit rows, so in a finished piece side borders in the same stitch type should be considered.
Adding color changes in the ground requires altering the repeats.
Hand techniques may be used to modify ribs by cabling, racking, transferring stitches to the backing. When knitting again on empty needles, if you want eyelets, simply keep knitting. If not, hang the pull loop from the adjacent stitches on the opposite bed before resuming knitting.
Cable color placement must be reversed at the cable crossing.
Racked sequences are made along with stitch transfers.
To emboss other than vertical ribs the needle selection needs to be changed every 2 rows. This can be done manually, following a chart, or with programmed patterning whether with punchcard or electronic options.
Plaiting can produce 2 color variations without color separations.
When increasing stitches, moving the adjacent stitch onto the new needle, leaving it empty, will change the eyelet location a stitch away from the edge.
When moving stitches for decreases, lateral transfers may be made with multiple stitch transfer tools for different effects.
Transfer carriages can speed up the process.
To start the pattern one can begin with a cast on only on the ribber or back bed, or transfer non-selected stitches after the first preselection row on Brother as seen in most of my previous swatches, with 2 rows knitting on the backing alone, and 2 rows of the main color knitting on both beds. With either cast on, the preselection row is made toward the color changer with needles in work position on the main bed, so the knit carriage needs to be set to slip so as not to pick up unwanted loops on the top bed as it moves toward the color changer, and will remain set to slip both ways throughout the pieces.
As mentioned, the term Milano refers to ribs composing weft knit structures where one side of the fabric knits more rows than the other.
In half Milano, a single long stitch is created in the pattern color, in full Milano small stitches alternate with a row of longer stitches created when traveling back to the color changer.
The preselection start is determined by the type of long stitch, and how the repeat is programmed. I prefer to start my repeats with knit rows.
A half Milano swatch is begun with all stitches on the ribber bed, COR: the needle actions for each design row if patterning were on every needle are shown below. Designing may be easier to plan or chart on a template, followed by actions for each pattern design row with the second color. Half Milano on left, full Milano on right for use in 2- color-work. 
Half Milano stitch formation on the left, full on the right 
Planning for a half Milano shape design outlined with added borders and with vertical columns at intervals in the alternate color: every 4th row is marked in yellow as the underlying template. A simple shape is charted out, marked with black cells, the pattern starts with a knit row. Preselection in slip stitch is made toward color changer, black pixels will pick up stitches moving to the right, slip top row moving to the left. Decreasing to maintain the dominant color shape is not necessary, while the border, in this case, is shaped by decreases made by transferring non-selected needles to the ribber before knitting with that color from left to right. Border cells are added immediately up and to the side of those planned for knitting on the previous row, their respective cells are outlined in green. Software programs make it easy to alter the repeats and add borders if wanted
Actual knitting will indicate whether adjustments are needed in making the repeat continuous vertically or with some added striped ground only rows in between. I had not noticed a stitch hung up on a gatepeg, explaining the distortion in the row marked by yellow arrows, where the yarn was caught and pulled up. 
These techniques share some features with the category of double bed appliqué, where one bed knits the main fabric while the other creates the shapes, which are attached to the fabric as you knit. In the finished fabric the purl side is the right side, the ground may be created in a solid color or striped. Both shapes are knit at the same time, as opposed to performing the technique on a single bed. As usual, the color changers should be threaded so that yarns feed smoothly and do not cross. With simple shapes as in shadow lace, no punchcard may be necessary, while cards or electronic repeats simplify the steps and help prevent mistakes.
In Japanese machines, for each row in the charts 2 rows are knit in the background first on the ribber, followed by 2 rows in the shape color on the alternate bed.
Smooth yarns and contrasting colors that still allow identifying knit structures easily are best. There is a limit to the number of colors that may be knit at once. Beginning with hand techniques: it is good to chart out the design before tackling it, and with color changers limited to holding 4 colors, if planning several shapes, the sequences in the color changes may need to be plotted out ahead of knitting as well.
Purl loops are the tops of the stitches in the row immediately below the stitches on the needle on the opposite bed, marked in green, while sinker loops consist of the yarn that is between the stitches on the needles, marked in red. Hanging the purl loops will help to eliminate or reduce the size of the eyelets. Take care not to use the sinker loops between the stitches, marked in red. 
In executing the fabric as a hand technique, the main bed is still set to slip in both directions, the ribber to knit every row
1. Knit 2 rows on the ribber alone
2. Bring needles to be worked in the pattern at the upper working position D or E, hang loops from ribber if there are increases if preferred, knit a row
3. Bring needles in pattern manually to D or E again, knit the second row of the appliqué
Repeat steps one and 2
In published directions color 1 usually refers to the ground color, which knits on the ribber only. Color 2 generally knits on the patterning bed as well. When most needles are in work on either bed, the tension for the yarn on that bed approaches the one used for that same yarn if it were being used single bed.
Punching all squares in 2 consecutive rows, or programming 2 all-pixel rows filled in completely across followed by two unpunched blank or all white pixel rows makes the process quicker. Punching or filling in single rows may be done as well, but requires elongation X2. 
Increases or decreases may be done on more than single stitches, and less frequently than with every pattern pass.
Fully fashioned shaping alters the edge of the appliques and places the eyelets in pattern, at or away from the edges. In Brother machines preselection of needles needs to be retained after any stitch manipulations.
Adding shapes with additional eyelets: practice shaping, keep notes, fully fashioned=FF 
Begin with simple shapes, examining the quality of increases and decreases, whether single or multiple, eyelet formation. Picking up from the row below before the next pass with the contrast color eliminates eyelets
picking up from row below at any point during knitting 
decreases in the number of stitches, in contrast, may be made by transferring down to the ribber prior to changing back to the ground color 
Simple increases or decreases are made by moving stitches laterally in either or both directions. Increases may be made by moving contrast color stitches laterally, followed by the choice as to whether to fill in the empty needle or allow it to create an eyelet. 
Fully fashioned increases or decreases are made by moving a stitch or a group of them to the adjacent needle/s to the left or the right and then taking the double stitches back to the original position, leaving a single empty needle for the planned eyelet formation. There should not be multiple needles with no stitches on them unless the goal is to expose a stripe of ground 
typically, in these exercises, there should be single empty needles after transfers, making certain proper needle selection for the pattern group is maintained 
Combining eyelets with lateral increases
When transferring stitches, watch for any loops getting caught on gate pegs, as seen on the left below, increases and decreases may be pre-formed on more than single stitches
Planning a medallion: cyan cells represent transfers to the left, the magenta to the right. 
At the top of the single medallion, the stitches were transferred to the ribber prior to knitting with the same color once there was no needle preselection for it on the top bed.
Programming repeats to help track needle transfers as well: it is possible to start with a published repeat, though once the principle is understood, required markings for DIY become easier. Electronic machines leave one free in planning repeat width. In this test, a repeat from the Stitchworld pattern was used. In its built-in memory format, it will not work, the repeat needs to be altered. Each sequence of passes with the LC consists of 4 passes, followed by two rows knit with the KC. Two rows are added to each lace passes sequence, which will knit on the ribber only, in the contrasting color. Transfers to left and right are marked in cyan and magenta. The specific software used or machine model may require that the repeat be flipped horizontally prior to being knit, true on my 930. Markings on the left are for ribber actions and settings, those on the right for the main bed. K indicates that that bed will be slipping, K that it will knit. 
The first preselection row after the chosen cast on is from right to left with end needle selection canceled and the knit carriage already set to slip in both directions, with all required needles on the top bed in the B position.
Transfers are made prior to carriage passes made with the pattern color, in this case, white. If a transfer patterning row follows a white row on the ribber, extra white rows will appear on the striped ground seen in this test, where the ribber remained set to knit every row in both colors 
To eliminate the extra white rows, the main bed stays set to slip every row, the ribber settings alternate. It is set to slip for two rows immediately after knitting with the red yarn, then will be reset and knits for 4 consecutive rows. Transfers to create eyelets are made on selected needles on each of those two rows, always toward the carriage, even as the transfers themselves change directions as the angles of the shape decrease toward its center on the top half of the design. After the first transfer and the carriages travel to the right, a long float will be evident, will “disappear” on the return to the left. 
Patterning selection will reappear as the carriages return to the left. 
The color is not changed. The ribber is set to knit in both directions again, forming stitches on both beds for the first two rows, followed by a color change and knitting in the red, on the ribber only for 2 rows, completing a sequence of 4 knit rows before the ribber being set once more to slip. For consistency, I changed the settings on it to slip before picking up the white, changed it again after preselection of lots of needles meant the top bed stitches needed to be knit on both beds again. The first proof of concept, observing choices: as with other samples, the first patterning row after all stitches are transferred to the ribber 
requires a choice as to whether to pick up from the row below or simply allow empty needles to pick up loops on the next pass, the choice throughout here, marked A. Reducing stitches may be done by transferring down to ribber, B, or lateral transfers, C. D marks the spot for a possible shape design shape. Arrows on the purl side point to the direction of transfers, cyan to left, magenta to the right 
As with single bed lace, the first pass after transfers creates loops on empty needles, which here need to be kept in upper work, D position after transfers. For non Brother knitters, Brother positions are A, B, D, E, skipping C. 
Knitting over the loops on the next pass on that bed completes the stitch. This design is knit as continuous, the striping at the bottom is wrong because the red was not picked up after the first 2 rows knit in pattern with white, most sequences for the remaining fabric are 4 passes with white in the feeder, followed by 2 in the red. All eyelets here are reduced in size by picking up from the row below, all transfers for decreases are made laterally, the border is set to a width of 4 stitches, the pivot point for the repeat has been narrowed 
the differences at the edges of the shapes. 
Many of the same principles may be applied to designs using tuck stitch settings, where the striping will appear vertically rather than horizontally

Large scale mesh, a punchcard repeat adapted for electronic

2020: Revisiting large eyelet lace, hand transferred (or not)
This was the punchcard provided in the first post, knit with 4 passes of each carriage, the knit carriage set to tuck in both directions 
Brother punchcard machines do not advance pattern rows when two carriages are used for needle selection as each carriage begins to move from the opposite side, the same preselection is repeated. This means editing is required at times if the same designs are to be used on electronic machines, particularly true in lace combination fabrics. The process has been discussed in posts on automating lace edgings with slip stitch settings.
End needle selection is canceled in both carriages, if any end needles are selected prior to a lace carriage pass, they need to be pushed back to B position manually in order to avoid transfers resulting in decreasing stitch counts or dropped stitches.
All versions proposed below share transfers that result in 3 stitches on a single needle, with two empty needles on each side of them. Here the needles are preselected for the next pass which will begin to fill in the double space, the needle in D position will knit, the one in B position will tuck; 
this is how the yarn is laid over those 2 needles after the first tuck row is completed, 
and both when using the card and in the first electronic repeat there will be a third tuck loop that is laid over the needle holding the 3 stitches. This is the appearance of the stitch formations just prior to an all-knit row 
Here analyzing the actions of the punchcard, marking rows according to card actions, the repeat is expanded to include the extra duplicate rows. Though the repeat remains 24 stitches wide, it is no longer usable for use on a punchcard machine. 
For knitting on the 930, the design requires flipping horizontally in order to knit properly. 
The third tuck row may be eliminated to produce an extra all-knit row, resulting in a slight difference in the shape of the eyelets 
Lastly, the repeat may be amended with extra stitches and rows between each eyelet 
Origami inspired 2: more pleats and folds using ribber
Periodically I search out previous drafts, this post was started in September 2019. Drawn to folds in a variety of ways again, I am publishing it in progress with the intent of adding more information and related swatches.
Some previous posts with related topics and technique swatches:
origami-inspired pleats1, racked patterns Passap/Brother 2, ribber pleated fabrics, and some possible needle arrangements 3.
There are many considerations if long panels or wide ones are required when setting up repeats in addition to what happens at the edges of patterns in racking as one bed moves near or past the needles in work on the opposite bed. If something like a skirt is planned, the choice must be made as to which side of the knit is preferred, and the end stitches of each panel should be on the underside of the piece unless the join is a deliberate design feature. To achieve that, some panels may need to be wider than others. If the pleats are bulky and involve deep foldovers, panels may be attached to yokes to reduce bulk at the hips. If working from illustrations for pleats for another brand, the needle setups shown may need to be reversed, or, since many such fabrics are reversible if manually set up with no additional patterning on the Japanese machines knit bed or European true double bed they can be knit as illustrated. Lock settings for the Passap are given with the back lock first (ribber settings on Brother), then for the front bed lock (top, knit bed on Brother). Cast ons must be fairly tight so there is no flare at the bottom of the pleats. They usually start on a standard needle setting. Needle transfers are usually made after the cast-on is completed, sealing the stitches with one row of all knit stitches. Swatches should be a minimum of 100 stitches wide by 100 rows if the end goal is a gauge significant garment. All fabrics with texture may change in both appearance and gauge after a period of rest. Some shaping if needed may be obtained by tension changes, OOW needle arrangements on either or both beds, or stitch type within folds (ie adding fisherman, half fisherman, EON patterning, etc.)
Pleat formation on the double bed is “easy” because the pleats are formed “automatically” according to the needle arrangement on each bed. That is true if the resulting folds are created by stocking stitches in vertical bands. My goal is not to provide patterns. There are many well-written ones easily available.
How small can one go? A tiny pleat: 
It is easier to transfer stitches when the ribber is set to P (Passap handle up).
Remember to return the setting to half-pitch before continuing. The pleat is reversible, shown on both sides, reminds me of shadow pleats 
racking by one position X3 at first, and then X 5 in each direction did not produce results worth the effort IMO, the result is subtle, the reverse side of the fabric is slightly stretched in the bottom photo. 
Here the fold is created by 2 stitches tucking for 2 consecutive, then knitting on the same needles for 2 rows on regularly spaced pairs of needles on either bed. Most knitting is on a single bed. A lacey series of eyelets begin to appear, and in some random racking at the top of the swatch, the possibility of developing a secondary pattern due to the combination of racking and tucking begins to show. The middle image is of the fabric slightly stretched. Passap 
Brother: the ribber can do the stocking stitch background, every needle in work, carriage set to knit. The setup is the same as the Passap diagram. A repeat with 2 black rows of squares followed by 2 white can be programmed on the top bed. On every needle selected rows, pairs of needles will knit, on the white, no selection rows the same pairs of needles will tuck for 2 rows. 
Moving away from vertical ribs becomes significantly easier if one has a G carriage. The alternative option is to create geometric folds that require transferring between beds. Any of these fabrics are best knit in a yarn that has memory and can spring back. Yarns such as acrylic can be permanently flattened by pressing, resulting in loss of texture. A quick experiment: black cells represent knit stitches, blue purl ones 
The needle setups: after casting on, transfer for a stitch configuration based in this case, of blocks that are 5 stitches wide. A single needle on the opposite bed is used on each outside edge of all needles in work. 
When there are no groups of stitches in work on both beds the pitch can be set to and remain on P, which also will make transfers easier, as needles will be point-to-point. The ratio used in the test was in multiples of 5. The groups were 5 stitches wide, 15 rows high, with all knit 10 rows in between the repeats. The fabric is shown first relaxed as immediately off the machine, then lightly steamed and stretched. The yarn is a 2/18 wool, far too thin for this use, and likely to flatten considerably with pressing. The close-up of the purl side offers a better view of the resulting folds 
The repeat, 10 stitches by 40 rows.

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 colors
Tiling 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
Bowknot aka butterfly or dragonfly stitch in more than one color
There has been a resurgence of interest in this stitch in the FB machine knitting group and discussion exploring a variety of methods for creating it. The inspiration, taken from a commercial sweater-knit: 
For some single-color variations see Bowknot/ Butterfly stitch on the machine and No longer a mystery pattern.
I program repeats whenever possible, and find it useful in eliminating errors, particularly in longer pieces. My first experiments for this fabric were conducted using the fair isle setting, which is essentially a slip stitch automatically working 2 colors with each pass of the knit carriage single bed.
Slip stitch patterns with hand-transferred stitches, single bed explores some of the methods for bringing slip stitch floats to the knit side of these fabrics, which is part of the hand techniques necessary to achieve the colored versions. As with any knit fabric yarn qualities, color contrasts, and tolerance for proper stitch formation are all variables.
For vertical columns in 2 colors, it is only necessary to program a single, fixed row with a punchcard or electronic, or choose any pixel-based repeat akin to this with full pairs of alternating stripes. I like to plan with selected needles at each end of the sample 
With the machine set to FI, needles not selected will knit a ground color, while selected needles will knit the color in the B feeder. It is easier to manipulate the slip stitch floats from purl to knit side if working in the non-selected groups of needles. Having the columns in odd numbers of stitches makes it easier to handle steps that require finding the center needle in each group if one is wanting to maintain symmetry. In my first test, I manipulated only the selected groups of needles to work the float movements, leaving the floats from the other color undisturbed, which makes the process far more convoluted than it needs to be. In this and the subsequent sample, I manipulated the left and right-hand pairs of floats moving them to the front of the knit, leaving the choice of what to do with the remaining center floats. In A they were brought up on top of the center needle in E position before knitting the next row. In B they are lifted into the hook of the needle and brought out to the B position so that the stitch is knit in color 1, while in C the remaining single stitch floats are simply left alone. In a couple of spots the yarn split, getting hooked up creating bleed-through, and what would result in an issue if that happened on the group of floats that were to be moved. 
As stated, the process is easier and quicker working on non-selected groups. Above, the yellow yarn was thicker than the blue. To maintain proper color selection in the non-selected column, the center needle needs to remain in the B position, with the slipped stitch forming floats below it before the next row knits. If the needle is brought out to E, it will knit in the contrast color, forming floats in that color on the purl side, and a knit stitch in what was planned as an all-solid column on the knit. The results are seen at the top of the first sequence in the swatch. I chose to limit my number of floats to 4 to keep the process manageable, moved stitches on the left of the center needle to the front of the knit, and then followed with those to its right. One of the many things to explore in hand technique fabrics is finding a way to handle tools that may be more comfortable than others, practicing on single blocks of color first can help establish that. Below both yarns are equal in weight and thinner. The floats formed by the color in the B feeder are also hooked up on the center needle in each vertical group in that color, forming a pattern on the purl side as well. 
The needle position for selection for B feeder yarn also needs to be maintained. Bringing the needle out to E ensures it will knit on the next pass. In both of my tests, the slip stitch floats on the knit side lie more horizontally than the lifted-up floats on the purl. 
Other ways of working the fabric, along with a history of the FB thread offered by Claudia Scarpa including a single bed slip stitch version with an English downloadable PDF http://ratatatata.it/dragonfly/.
Her youtube video illustrates a different way of managing floats than mine.
JuliKnit offers 2 videos knit on Silver Reed 1, and 2. Both are knit using the ribber, the first method uses holding to gather loops on each of the beds, and the second begins to address automation for needle selection on the top bed using DAK, with the selection on the ribber remaining manual. The stitch illustrations generated in DK offer knit stitch simulations such as these 
Executing her versions on a Brother machine requires some interpretation. The fabric is constructed using the ribber in conjunction with the main bed. The vertical columns are 5 stitches wide.
Colors are worked one at a time. If a color changer is to be used, an even number of rows would be required for each pattern segment. For 4 floats followed by an all-knit row, the repeat would be 5 rows high, so one consideration would be operating with the second color from the right, requiring free passes. Studio machines release the top of the knit carriage at an angle from the bottom, so that explains the move seen in the video for the carriage to be moved to the right. Brother machines use the slip stitch setting in either or both directions, to achieve that. Using both buttons avoids any confusion. All needles in use must be in the B position for the “free pass” to avoid dropped stitches. The number of rows gets adjusted in the videos eventually to 6.
When working on the top bed, the ribber is set to slip both ways.
For those unfamiliar with Studio settings a brief review: the Studio SRP60N ribber introduced the option for knitting emulating the lili selection in Brother. 
The grey plastic piece on the left of the studio ribber, the autoset lever, when cleared would essentially duplicate setting Brother levers to slip manually in both directions, clearing it again would return it to knit. 
Cast on either EON or EN rib. Transfer needles in a 5X5 rib beginning and ending with a single needle in work on the ribber on the far left and right, setting up the initial needle arrangement for the fabric. Black dots represent needles in work on both beds, and the red ones the initial needles that will be worked in the holding position on the top bed. 
The video knits each color for an even number of rows. Bring the first and last needle into work on the ribber before knitting each row. The remaining stitches are knit only on the main bed. The knit carriage is set to knit, the ribber to slip in both directions. Pick up the chosen color on the left, and knit for an odd number of rows, when the carriages are on the right, push held needles back to work position so they will knit on the pass back to the color changer. The ribber knits the next color. A review of the Brother ribber carriage for those not familiar with it 
COL: the main bed will now slip in both directions, set it accordingly. The ribber only knits. The center needle on the top bed that held the butterflies is transferred down to the ribber, illustrated in the red dots over black ones. The center needles in the blank areas on the ribber, blue dots, are brought up to hold, the ribber levers are set to knit in both directions, holding levers are set to hold in both directions as well, 
knit for an odd number of rows, with carriages on the right, push held needles back to work position so they will knit on the pass back to the color changer. COL: the knit carriage changes back to knit settings, and the ribber slip setting in both directions is restored. The center stitches that formed ribber butterflies are transferred up to the top bed, and needles at the center of the blank areas on the top bed are brought out to hold. The color is changed, and the process begins again. 
My first efforts were met with dropped stitches after a few rows and expletives. My second effort fared no better, I simply could not avoid dropped stitches on either bed, perhaps because of my yarn choice and the small tension it required. Working on the single bed once more, using the slip stitch setting and knitting one color at a time, I achieved a fabric more similar to the original photograph. The chart reflects the number of needles in my test swatch, with a 2 knit stitch border added on each side 
Each color knits for 4 rows. At the end of each 4-row sequence, the non-selected needles allow for manipulation of the floats. 
The transfers in the piece begin on row 5. Before the next row is knit in the alternate color, the slip stitch floats are reconfigured, bringing stitches 1 and 2, 4 and 5 in each group to the knit side of the fabric, leaving the center floats undisturbed. 
Bring the whole group out to the E position so they will form knit stitches with the first row of contrast as the carriage moves to the right. 
Knit 4 rows. The carriage will once again be on the left unless 2 carriages are in use from opposite sides. The center needle in each group of 5 will be left unselected. 
Lift floats up onto that center needle, and bring it out to E position so that it will form a knit stitch in the next color to be used. 
The final result is closer to the original
Slip stitch patterns with hand transferred stitches, double bed
It is also possible to create solid color patterns on the purl side on a striped ground by at first transferring all stitches down to the ribber, then, in turn, using slip stitch selection on the top bed to choose only the stitches that will be manipulated on the main bed. A similar repeat worked on the single bed, may be found in the previous post on Slip stitch patterns with hand transferred stitches, single bed. And a relative, including a double bed version: Bowknot/ Butterfly stitch on the machine, and: A no longer “mystery pattern”.
When working over a striper backing, the color changer is generally in use, and changes happen in even numbers of rows. In my test swatches changes are made every two rows, and whether single or double bed, the color yarn creating the solid color shape needs to not knit while the alternate color is worked only in the background. The held stitches grow in length.
End needle selection is canceled in my samples. 
The extra needle selection prior to the next all knit row helps track the direction of the moves, stitches are moved three at a time, there are no cable crossings
Things do not always “work”, that is part of the process 
The next step for me was to explore cable crossings on elongated stitches working double-bed. A basic pattern on any programmable machine for playing with elongated stitches on one bed while knitting every stitch on the other is to program pairs of blank rows followed by solid punched or black pixel rows. The yellow line in this chart illustrates the row on which cabling might occur. 
Programming the width of the needle bed allows for only the stitches forming vertical columns in chosen locations to be put into work, allowing one to place groups that will involve crossings anywhere on the chosen pattern width. A base is knit in the ground color, which slips for 2 rows on the main bed, creating the elongated stitches that will be cabled. I had no problem with 2X2 cables, 
but as in working on the single bed, for me, straightforward 3X3 crosses were not cooperative, even when I attempted to introduce extra knit stitches on the sides that were then dropped for added give on the last slipped row, taking me back to the drawing board. 
Cabling, returned to in a later post, with adjustments, making things work.
Continuing with shapes on striped grounds, this is the result of a self-drawn pattern 
The approach is different than in the blog post on Brother shadow lace, rib transfer carriage, where shapes were created in only one color, and the textured patterns by bringing needles in and out of work on the ribber. To create the striped ground in the above, color changes happen every 2 rows. The ribber knits every needle, every row. With the ribber on half-pitch, the transfers are all made from the main bed needle to the needle immediately below it and slightly to its left.
In the chart on the left, the green cells represent black pixels that will be programmed for patterning on the top bed, red cells, the stitches on the top bed that need to be transferred down to the ribber on the respective row.
Grey cell rows stand in for all blank ones in the final repeat. 
This design is too wide for punchcard machines, but the fabric is possible there as well in different widths, isolated or all over. After casting on, all stitches are transferred to the ribber. Border, plain knit stripes can be added by simply having a larger number of needles in work on the ribber than the planned pattern width. With no needles selected in the pattern on the top bed, those ribber stitches will simply knit every row.
These fabrics are a little different than those with needles out of work on the main bed while using the slip stitch setting, in which case KC II on electronics, end needle selection needs to be turned off on all models. When all needles are in B position, depending on the pattern, KCI may be used. Simply using KCII eliminates any guesswork.
The first preselection row is toward the color changer with the knit carriage set to slip in both directions, only patterned area needles need to be in work. Non-selected needles, as usual, perform no function while those corresponding to where black pixels or punched holes occur will pick up loops on the top bed, initially creating eyelets, and then continue to form knit stitches until any of the corresponding stitches are transferred down to the ribber. The pattern yarn forms a short stitch in one direction, an elongated one in the other. A detailed close-up of stitch formations 
Plain striped rows in areas without the design continue to be knit in the slip stitch setting, or every needle in work on the top bed will pick up loops.
When hand manipulating stitches it pays to be mindful of maintaining all needles in the pattern in B position, not accidentally sliding them back to A. 
In the past, I have attempted pile knitting on my machines. Studio machines produce the best fabric in the category, I have read Toyota performed as well. Books such as this are a good source for pile designs, including the card repeat used in my proofs of concept 
Punchcards, in theory, may be used as given and set to double length, while for use in electronics drawing the pattern single height and using the double-length setting is also an option. Starting sides and fixing errors have always been more confusing for me when using the double-length feature, I prefer to punch holes or program pixels as I intend to knit them. The isolated reduced repeat for use in the electronic is charted, with an initial one-pixel error in 2 consecutive rows, marked with red cells. In transcribing any design, it is worth checking repeats multiple times after eyeballs and brains have had a rest. This was my start:
The design process using Numbers before exporting the repeat to Gimp for reduction to B/W png: in this approach, the repeat is drawn double height to start with. The red cells represent stitches that will be transferred down to the ribber before knitting the next row in the pattern color from left to right. 
The first test is of an isolated motif. The yellow arrow points to the pixel error, the cyan to the positions where some needles in the full repeat were “accidentally” placed in A position, not B, resulting in pattern stitches not being formed. 
Another review of the original card, a final adjustment in the repeat:
Tiled view, committing to the result, 
the larger test swatch 
Two other options for charting the fabric in numbers: A. draw the repeat as given
B. starting cell size used was 20X20, change the height to 40
C. mark corner blank cells and screengrab for Gimp import
D. the repeat processed in Gimp matches the first version
Any simple Fair Isle repeat may also be used. The numbering in the charts matches what is normally seen on the left edge of the tables
A. the FI repeat, 8 rows high
B. a table slightly longer than double the repeat height, hide even-numbered rows
C. copy and paste the FI design on the table with hidden rows
D. unhide rows, isolate the repeat, adjust cell height, and continue to process as described above 
The original punchcard design may be used in a different manner if the goal is a single color fabric. The design may be copied as is, then filling in the blank lines with the same holes or pixels as in the row directly below it. Here, in addition, the repeat is altered to accommodate a half drop repeat on the right with a few pixels changed.
My initial proof of concept is 32 stitches wide, narrower than the full repeat 
The rows need to be scanned before every pass, as transfers to the ribber are not symmetrical due to the shapeshift on the right of the design. 
The world of possibilities grows even further for single color shadow lace, when, examining the same design, one recognizes that the pile knit card, with the blank rows filled in in pattern, is the same as the fair isle version of the repeat, rendered double long 
Some authors have suggested plaiting as an alternative to creating shapes with true brioche, which can be complex. To my mind, plaiting falls in the beauty being in the eye of the beholder category, I prefer far crisper color distinction in my knits. This sample from the previous shadow lace post uses thick and thin yarns 
Using the image adapted from the studio pile card once more, I tested using 2 yarns of similar weight, the adjusted test repeat: 
its accompanying test swatch 
I have long been interested in pleated knits, both single and double-bed. Working single color or with plaiting makes the repeats easier for DIY designing. Seeking proof of concept for possible “origami” pleating: on the left, yellow marks the spots for transfers to the top bed, which will create folds out toward the knit side. For folds toward the purl side, stitches are manipulated on the ribber, with the final design repeat shown on the right. 
The ribber carriage is set to knit throughout. The needle from which the stitch is transferred to the main bed is moved completely out of work. After the transfer, the main bed needle accepting it is returned to the D position.
The knit carriage is set to slip in both directions, end needle selection is canceled. Subsequently, non-selected needles, 1 in the photo, serve as guides for transfers to the ribber, made every two rows. The needles emptied from the transfers need to be maintained in the work, B, position. The selected needles, 2 in the photo, will pick up loops automatically, creating eyelets as seen in previous swatches. 
The swatch would have benefited from tighter tension or thicker yarn, the folding effect is greater than reflected in the photo. Initially, those pairs of center stitches were not transferred up to the main bed, showing the absence of that fold when that action is omitted. Any of these patterns benefit from deliberate planning of the placement of the pattern on the main bed, not done in this instance. Transitioning to smaller repeats, tiling will help avoid patterning “errors” as seen here where the full diamond shapes reverse 
Graph paper or spreadsheet planning will help avoid misses in necessary transfers in areas where all needles have been selected 
the file for multiple repeats after color reverse 
the test knit as using transfers as described above and here the empty needles creating the eyelets were filled by picking up the purl bar from the stitch below on the ribber. A lot of work for a change that is not significant in the structure of the fabric. 
In my last test on eliminating holes and how that affects the degree of the folds, transfers to fill in newly selected needles on the top bed were made from below the adjacent needle on the top bed, B, as opposed to immediately below on the ribber, A 
If patterning is used to track transfers, needle selection on the top bed needs to be maintained throughout, the result of this process is not interesting enough and just too fiddly and time-consuming for me to be interested in exploring it further 
There is an interesting scale and depth of fold comparison between this version and the first using the repeat, achieved by tightening the tension as much as possible, and possibly by reducing the size of the eyelets. 
Exploring manipulations with more than one color patterning on the main bed: there is a type of DBJ that relies on knitting the same color for 2 rows that is inherently different from the KRC built-in separation that is the default in the Japanese model machines. It causes elongation in the design, while the KRC version minimizes it. The differences and methods of the corresponding color separations have been discussed in other posts. Stitch manipulations may occur when working DBJ as well. Simple designs make the best start for beginning to explore the topic 
An easy variation is to plan full repeat segments mixed with a striped ground worked only on the ribber 
Take care if copying and pasting single columns to alter a repeat width that the whole column is indeed copied and that if using the pencil tool flood fill is not used unintentionally. The original intent was also to correct the elongated slip stitch segments on the edge of the programmed vertical designs marked in blue, but the paste with errors in red accomplished creating the same issue 
The design is programmed for DBJ. Because of the color separation used, the first preselection row is from right to left. Before knitting the first pattern row, all 10 non-patterning needles on the main bed were transferred down to the ribber. 
The first segments were knit using striper backing, with the ribber knitting every stitch, every row, in both colors. When a slip stitch is used with needles out of work on the main bed, end needle selection should be canceled. In A it was not. The result is that end needles alongside the out-of-work column knit with each color in each row. In B, end needle selection was canceled, and one can now see the elongated slipped stitches that result from areas that should have been marked with the contrasting color 
As long as the number of stitches on the ribber is even, lili buttons may be used, affecting the scale of the pattern in both height and width. In A, they were used with the ribber set to slip in both directions, in B, set to tuck in both directions. C marks the return to the N/N setting, with needle transfers to mark a possible pleat. 
The initial pleat idea charted out for single stitch folds, stitches transferred to ribber in the R columns, to the top bed in the T columns 
The result is a fairly soft pleat, the choice below was to retain end needle selection. 
Various ribbed pleat configurations are explored in Pleats: ribbed, folding fabrics. This repeat may not be the best to use for a variety of reasons, but experimenting while using the same design and yarns can be useful in understanding stitch formations. Theoretically, the alternating direction of folds should create sharp or knife pleats. 
Paired transfers in the planning stages: because the repeat is small and has a single center pivot point, it is rendered once more, adding columns
Here the transfers planned to opposite beds are marked on a 48 stitch repeat with red cells.
The resulting fabric relaxed on the left, lightly steamed on the right 
Note: the color positions in the design have been reversed from those in the first swatch. If “floats” are noted at any time in the spaces where needles are out of work on the ribber, look for dropped stitches.
Vertical bands of color, even in patterns may be transferred to and from beds to achieve a sort of intarsia effect. One option is to work with vertical bands of fixed color, using the KRC built-in separation. When shifting gears it is useful to remember the starting side for the preselection of the first row of patterns. With many of the previous patterns, designed for color changes every 2 rows, starting side was on the right, toward the color changer. With KRC in use, the first preselection row is away from the color changer on the left, moving toward the right. With either method, starting on the wrong side will knit stripes as opposed to planned patterns. 
Needles in locations where only the backing is to be shown are transferred down to the ribber. Leaving the eyelets, they were transferred back up to the main bed when brought into work to reverse or change the shape. Addition and subtraction of stitches take place before the next pass with the alternate color. Here movement is random, to get some sense of the effect, it could be made deliberate by following a chart or color separating and automating the pattern, with its starting side on the right. 
This sample is from a much earlier post. Transfers could be made less frequently to change the angles in the resulting shapes, always onto the same color 
What of having shapes appearing in each of the 2 colors on a striped ground? Eliminating some of the guesswork I used the repeat from a previous single-bed blog post on block slip stitch color separations 
The repeat, 32X44
The resulting sample, the yarn is thin, might have benefited from tighter tension and more contrast. 
These fabrics and related shadow lace ones fall in the category of double bed embossed patterns, many more variations are possible, and deserving of their own post.
Knit weaving 1
In knit weaving, the knit carriage is threaded with the main yarn as usual. The choice of pattern is determined by needle selection. The most basic technique involves pulling the desired weaving needles forward manually or by using needle pushers which are available in a range of selection options. Automatic needle selection makes the process faster, consistent, and capable of more variations.
The weaving yarn, according to instructions in manuals, may be threaded through the tension mast and guided through the weaving yarn guide. Feeding thicker yarn smoothly through the standard mast may become problematic. Moving yarn from the groove on one side to that on the other is cumbersome. The punchcard machine manual for the 860 machines has some clear illustrations and directions 
From the 260 manual: 
The “yarn guide” is that mysterious notch in each arm of the sinker plate. In the Studio accessory, the AW1 weaving arm, the yarn is also fed through the yarn mast, and moved physically from side to side after each pass of the carriage. 
Start the piece with waste yarn and some evenly distributed weight based on fabric width. Make sure the weaving brushes are activated. In Brother standard, their position is changed using the corresponding lever, in the bulky 260 the L and R wheel brushes need to be placed in their corresponding slots. 
A good repeat, to begin with, is one that selects every other needle, every other row. The card is a standard factory issue with punchcard machines. 
In general, the knitting yarn is thinner than the weaving one. The tension needs to be adjusted to accommodate the surface yarn, not the background one. The tighter the tension the firmer and narrower the weave. It is also possible to create soft knits with a lot of drape ie by using sewing thread for the ground and fine mohair for the weft, there is a huge range for exploration.
The “weft” precedes the base knitting yarn which knits the stitch. It is laid over the top loop of the old stitch on a needle selected by a hole in the card and goes underneath the top loop of a previous stitch on a needle not selected by a blank on the card. When card 1, above, is in use, the weaving yarn is caught in a series of two loops, one above, and one below forming a honeycomb effect. The structure is typically illustrated this way in Japanese reference books and magazines in particular. 
Early Brother punchcard volumes have illustrations of the over_under structures and in between floats along with providing the pattern repeats. 
Setting things up: the weaving yarn is in front of the machine, fed from the floor. The short end goes to the carriage side, the long end is away from it. It is laid in front of the gatepegs, atop selected needles. A clothespin can provide enough weight on the short end to keep it from riding up and having to be managed with one’s hand. “Weaving” can begin from either side, here it starts on the left. Knitting in 2-row sequences will return the yarn ends to the starting position. 
Locking the card, as with any other pattern, will repeat the same needle selection, creating vertical repeats that resemble twill weaving on a loom.
a: card set to advance normally, b: card locked 
a: because stitches are actually knitting every other row, slipping while the needles on each side of them knit, they will alternately be a bit elongated; b: same needles knit every row, so their appearance is consistent. 
Depending on the difference in yarn thickness, the knit stitches in the ground become forced apart with what can be significant “bleed-through” on the reverse of the weaving to make that a really interesting fabric feature as well.
Some weaving patterns with variable floats will produce better edges if the end needles are brought out to E in every row if not selected to that position by the reader.
If a hairy or fuzzy yarn such as mohair is used it is possible that the fabric will start to bunch up, it may be necessary to reach up from behind the knitting and gently pull to release the little hairs from the gate pegs.
Most punchcards designed for weaving aim for short floats formed by unpunched areas, longer ones on occasion are planned for added manipulation.
Moving the yarn from the groove on one side to that on the other is cumbersome. Another way of working: the main yarn is threaded as usual and the weaving yarn sits on the floor. The method is often referred to as intarsia weaving. The shapes may be created using various punchcard designs ie diamonds, squares, etc, free-forming, or even through following planned drawings on knitleader mylar garment shapes.
The knitter guides the yarn. If the yarn is held too loosely it may jump off the knitting while weaving and thus create long loops. It should be guided and held just enough to slip through the hand as the carriage is passed.
Preselect for the first row of knitting. Lay the weaving yarn across selected needles in the direction in which the carriage will be moving.
If using yarns of different yarn weights within the piece, multiple strands of the thinner yarn may be used together, but test how the strands feed and if plying might lead to problems. Using wrapping methods on some rows or even creating floats and hooking them up periodically can produce added interest.
If using more than one yarn per row, the approach is similar to intarsia. In true intarsia, every needle is in use. These illustrations are from an intarsia carriage manual; positioning the yarns for a first row from right to left, 
the “wraps” needed in each direction 
In knit weaving, assuming the first pattern row is preselected from left to right, with COR, the short end of the yarn of the carriage side, bring the first weaving yarn up from the floor, and lay it to the left across the selected needles, bringing it down between the last selected needle for A, and the first selected needle for B. 
In one method, bring the long end of the second yarn, B, up on the right side of the needle over which A just crossed, and lay it over the remaining selected needles and down to the floor.
Small clothespins may be used to hold the short ends in place. When all the yarns have been laid in, grasp the ends loosely, pass the carriage to the left, and the first woven row will have been completed. The carriage will now be on the left, COL. For the next row begin on the right, bring A up and between the two needles directly above it, take it over selected needles to the end of selected needles, and down to the floor. Then take yarn B and bring it up around the left-hand needle, over and to between the two needles that served as the starting position for A. The yarns do not overlap the same needle going to the right, but they do to the left.
The more traditional intarsia crossings may be also be used, with the new yarn passing under and over the old between needles, seen here with the next row to be knit from left to right. 
a: crossings made using the traditional intarsia method, b: wrapping over the adjacent needle moving from left to right, c: no crossing at all also revealing single knit stitches between weaving yarns. In some spots, my weaving yarn split and got knit along with the ground yarn. 
To create isolated shapes: lay the yarn in any chosen area 
Shaping may happen in a straight vertical, a, there may be a slight separation along that edge. Increases are possible on both sides at the same time, are best done by adding single new selected needles to the pattern, b. Moving further out crossing over more weaving needles will cause floats, as seen in c and d. The woven segment forces the knit stitches apart, so the stocking stitch on either side of the shapes, e, appears to be formed by smaller stitches, and pulls in toward the shape
The ground yarn and color may be changed for added striping and color interest. Sharp angles are created by crossing over two weaving needles, and more gradual ones by crossing over more needles. Blank areas of ground may be left as well.
The intarsia approach may also be used with other cards designed for all-over patterning.
Using far thicker yarns may be made manageable when changing the card repeat or using weaving repeats with 12-stitch wide repeats, working on specific needles on a punchcard machine, or simply programmed twice as wide on electronic ones. The expanded version of every other needle set up for the punchcard models. 
Sometimes plain knit rows need to be added between lines of weaving to help manage thicker yarns in any configuration or to add color interest and width changes to the piece.
Woven rows may be used to create folds in pleats.
Other weaving techniques include the pulling-up method, as a stand-alone or combined with lace patterning: from a Brother punchcard volume 
Three more hooking-up variations, including latching graduated-size floats 
A later experiment combining weaving with tuck patterning 
Hand techniques: e-wrap rows may also be incorporated with any of the above or used alone, sketches of some varieties may be used around every needle or every other depending on the thickness of the yarn: a sketch eons ago 
Vertical weaving Japanese instructions that came with the purchase of the standard garter bar. The accessory also came with foam-backed strips seen here clipped onto the width of the garter bar segment being used, they were useful in maintaining even spacing between yarn threads when working on wide areas of vertical weaving, as well as providing helpful weight. Any weight used to help handle the long ends of the weaving yarn on any number of threads will need to be moved down periodically. 
More wrap ideas
Variations can happen by changing the spacing between wrapped stitches, the number of rows between the moves, spacing threads apart, and using yarns in different thicknesses and colors.
In terms of tools to hold the weaving yarns, in addition to the garter bar, multiple transfer tools may be used, even bobbins. That said, the most efficient way is to have a guide suitable for the overall fabric, especially when creating wider pieces with spaced weaving repeats. It is possible to create cardboard guides with holes based on gauge, whether on the standard or the bulky and with 3D printing nowadays a whole other world for custom tools is open. Matching the gauge with guides has some leeway, but the closer the match, the faster and easier the process. When using thicker yarns for the warp knit, spacing in both stitches and rows becomes a necessity.
A half-hearted attempt at a template. Markings were generated to be point/mm specific. If working in narrow panels, individual segments may be more effective to manage if a bit slower to use than a wider tool.
This is the wrong way to feed the yarn, as the row gets knit woven in, the yarn will be locked in place and cannot be advanced to proceed up the knit 
The way to have continuously available yarn 
Adding a second set of holes for the yarn stabilize the short yarn ends and maintain even spacing throughout, some tape could be used in addition to secure the ends on wider widths of vertical weave 
A spreadsheet or graph paper may be used to plan the configuration of the weaves including double wraps, this was executed using Numbers, individual bobbins might be a practical consideration 
In my own experience most hand techniques and single bed textures are far easier to execute with the ribber removed. It is easier to view progress, move up weights, and correct mistakes. That said, my machines are all set up with the ribber brackets, not flat, I feel it helps slide the knit down toward the gate pegs, and in my opinion that makes textures and even lace easier to produce. I have ribber covers, they can be improvised if needed with paper or cloth, never use them since I see no reason for moving the knit on the top bed in front of the ribber. If the ribber is removed, it is worth checking its balance once more prior to returning to any rib knit. Ultimately this sort of thing is about personal preference, no steps are ever universally applicable and correct.
Tufting may be created with the help of a sewing machine.
“Weaving” foreign objects can be achieved by picking up loops from other knits, woven, trims, crochet chains, etc. Beads may be threaded onto weaving yarn as well.
Knit weaving 2: swatches, experiments
Many of these swatches are part of my stash from my teaching days. They were usually not intended for finished pieces, merely to illustrate a range of possible results with the techniques, often produced during my demonstrations. The colors were chosen to stand apart in the shared yarn stash in the studio, intended only for my personal use and for easier visibility during demos. The latter were being videotaped from some height and projected onto a large screen during classes for added visibility. At times enrollment was between 15 and 20 students per session.
Eyelets indicate tension # used for ground yarns. It is best to avoid dots between whole numbers. If swatches are too small to reflect the tension used, knots can be placed on yarn ends at the start of each experiment. The ends themselves may need to be doubled to make knots palpable.

Weaving yarns may be laid in between the beds with the ribber in use. This is the option for “weaving” on the Passap. 1: shows the rib needle configuration, 2: racking is added, 3: floats are teased out. In the latter, a sewing machine could always be used to anchor added float arrangements. 
In this swatch, a waffle weave effect of sorts was intended between EON rib columns. The horizontal pairs of treads are an easy guide for feeding the yarn across rows with the work off the machine. Here the chenille was “woven in” off the machine using a tapestry needle, double-strand at the top 2 rows, single below them. Beads can also be threaded and laid in one at a time between the rib columns, 
Any fabric with eyelets may be used as a ground for inserting fabric strips, very thick yarns, even hard objects such as rods or twigs. A quick grab of random studio bits resulted in these: torn fabric has frayed edges that can be used to create secondary patterns depending on the fabric, and the way the strips behave depends on the width of the cut. A bodkin is useful in the threading process. Bodkins measure about 3 inches, and cost about $3 in US sewing supply stores

Brother shadow lace, rib transfer carriage
I have probably owned this accessory since the early 90s. After making a faint-hearted attempt at using it at the time and failing, it has been stored in the original box in the interim and just came out of retirement. The multiple languages operating manual for its use may be downloaded from http://machineknittingetc.com/brother-ka7100-ka8300-transfer-carriage-user-guide.html. There are several video tutorials available on Youtube. As a group, they generally illustrate simple transfers across an entire row in structures such as ribs used for bands and cuffs. This one is offered by Knitology 1×1, Elena Berenghean, a young knitter publishing very good machine knitting video instruction on a huge range of techniques.
The tool is designed for the standard gauge and transfers only from the ribber up to the main bed. It is best to use yarn that has some stretch. The recommendation in the manual and in youtube videos is to perform the transfers with the pitch set to H. My own ribber is balanced, I found I had problems with transfers in that position, several carriage jams, and to get things to work properly in half-pitch I had to use the racking handle to move the ribber needles slightly more to the left for the transfers. The needles containing stitches to be moved, need to be slightly to the right of the needles with which they will share yarn, that spot may turn out to also be just wide enough to allow for the pattern to be worked without changing the ribber pitch. The yarn used is a 2/18 Merino, knit at tensions 3/5. 
In terms of positioning the carriage, a wire that is akin to that found on Passap strippers is on its underneath. In positioning the carriage on the beds, check visually that it is indeed lying between the gate pegs of both beds prior to attempting to travel with it to the opposite side 
If any carriage jam occurs, it takes cautious wriggling to release the wire and carriage. Upon completion of the transfers, simply lift up to remove it from the beds.
Generally, the ribber tension used needs to be set on 4 at the minimum. The last row just prior to transfers will likely need to be knit at a looser tension than the remaining rib. If the stitches are too small they will not be picked up for the transfer. Folks familiar with lace knitting are aware that just the right amount of weight can make a difference in forming proper transfers. With these fabrics, too little weight may result in loops forming on gate pegs, too much weight, and stitches may remain over closed latches on the ribber needles and not share their yarn for transfers. Again, the transfer carriage operates only from right to left.
Studio instructions for their version of the accessory actually offer some different and more specific recommendations. When knitting full needle rib all the needles or pattern segments the machine generally will be in Half Pitch. Though there are needles in work on both beds, the ribber should be set to full pitch, aka P position, “point to point” prior to transfers, bringing them in close alignment in order to facilitate the process. 
Passap machines accomplish the same by changing the angle of the racking handle to other than the full, up placement in order to achieve the necessary alignment.
The Brother accessory and its parts, have clear imprinted illustrations for use
The change lever has only 2 positions, up and down respectively 
Its position is determined by the number of needles on the ribber one wishes to transfer.
The carriage manual recommends its use after knitting a last ribbed row to the left, but it is possible to use it with both knitting carriages on either side, as long as there is generous space to clear all stitches when the accessory is placed on the bed, moved to the opposite side, and removed. An extension rail may be needed to achieve that amount of clearance.
Operating slowly, one can watch the process of transfers while moving from right to left. Though skeptical, I found the transfers happened easily, with occasional skips. I worked with hand-selection of needles on the ribber to create a pattern, first with hand-selection, then with racking the ribber position to change the relationship of needles on one bed to the other, initially transferred after every 2 rows knit. The knit carriage was set to knit both ways, the ribber to knit in one direction, creating loops on the selected needles, and securing them in the other, allowing for the loops on the ribber needles to be transferred up to the main bed, before working 2 more rows. The “errors” in patterning were operator errors in needle selection as stitches were dropped, and not all the required needles were then returned to work position. Not a technique I would use for all-over fabric, but good practice.
When the transfer occurs properly, the ribber needles will have yarn placed over closed latches, ready to be dropped, the yarn is shared and looped over stitches on the main bed, akin to tuck loops, outlined in the photo with the black oval. The first image is from the manual for the accessory, while in the photo, one improperly transferred stitch is outlined in red. To prevent dropped stitches from happening, any such locations will require a hand transfer to the opposite bed before dropping the remaining ribber bed shared stitches 
For my test I used EON needles on the ribber, planned alternating selection for each new transfer. This could be done by selecting dashes and blank spots on needle tape ie. dash in the above photo, blank spaces below 
It was faster to achieve the effect by changing the ribber relationship to the main bed using racking by one position ie 10, 9, 10, 9, etc. prior to picking up the subsequent set of loops. The errors in the test swatch were from failing to bring all the needles back up to work after dropping their stitches. Using a tool ie. a ribber comb placed over the out-of-work needles prior to dropping stitches made the racking process far less error-prone, will keep the appropriate needles from being accidentally taken out of work. 
My first attempt at creating shapes includes a band at the bottom where the EON transfers as above were made, but every row. Simply bringing needles into work on the opposite bed creates an eyelet. They can be eliminated by sharing stitch “bumps” on the opposite bed, but for the moment they are a design feature. The texture created appears in the areas involved on both sides of the knit 
It is possible to transfer single needles at sides of shapes ie 
or whole rows, but the change lever needs to be set to position accordingly.
Many knitters have one of these tools in their stash, they are sometimes referred to as “jaws”, intended to facilitate transferring between both beds, and patterning was intended for Studio punchcard machines. 
The enclosed punchcards: 
Shadow lace tools are marked side 1 and side 2. Some are blue on one side, cream or white on the other, the blue side is side 1. The process always begins with side 1, or blue. When the stitches have been removed, the jaws are closed, allowing the stitches to slide over to side 2. The jaws are once again opened, and the stitches are transferred to the opposite bed. Studio machines select and knit in single pass rows. Brother preselects for the next row of knitting while knitting any one row in pattern as well, so transferring in pattern from the top bed down with such a tool would be problematic to maintain proper pattern needle selection.
To transfer from the ribber up on any machine, place the teeth of the jaws on the needles on the ribber, holding it with both hands. Pull needles up until all stitches are behind the latches, then push down with another tool or one of your hands until all stitches are on the jaws.
Release the tool from the ribber needles, and rotate it away from you, toward the main bed. Close its teeth so the stitches are transferred onto side 2.
Open teeth, place eyelets over the main bed needles, and stitches are transferred onto the main bed by rotating the tool away from you just a little and tugging down a bit.
On Brother, the possibility of having patterning on the top bed to help track patterning on the ribber in some way comes to mind. This was my start, with the first draft of electronic repeats. 
I stopped when I began to have some tension issues, loops on gate pegs, and a distracted brain.
Transfers of stitch groups, whether by hand or using the accessories are made on rows where no needle preselection occurs on the main bed 
This series is a proof of concept for my approach to developing electronic cues
The original repeats were modified to include 2 blank rows between segments that allow for transfers between beds not hampered by needle preselection on the top bed. The motifs are color reversed, but not the blank rows between them. 
The knit carriage is set to select needles KC I or II, end needle selection does not matter. All needles on the top bed knit every stitch, every row, whether or not those design rows contain black pixels. No cam buttons are pushed in. Blank areas between black ones indicate the number of needles that actually need to pick up loops on the ribber to create shapes, filling in spaces between selected needles until an all-blank row is reached for making transfers. The chart on the far right illustrates a shape where the easiest method becomes one where stitches on the ribber are manually transferred to the top bed in order to reverse the shape and maintain every row preselection. The selected needle corresponding to the black square marked with the top of the red arrows is pushed back, the ribber stitch below is transferred onto it, the needle with the couples stitches is brought to E position, moving across the bed in proper locations prior to knitting the next row. 
In this repeat, the side vertical panels of ribbed stitches are added. The knit stitches on each side of them roll nicely to the purl side, creating what in some fabrics can actually be planned as an edging. 
My takeaway is to test the accessory with some patience, sort out the sweet spot for the ribber needles in relation to main bed ones in terms of handling transfers and yarn thickness, use colors that allow for easy recognition of proper stitch formation, keep good notes, and “go for it”.
One way to add color to the mix is to use the plating feeder.
In the first sample, equal thickness yarns were used, the colored yarn was a rayon slub with no stretch and slippery nature. The bottom of this test used a wool yarn of equal weight to the light color, which proved hard to knit. The red is a 2/48 cash-wooll 
A very narrow test for a possible pleated pattern 
It is possible to construct the same type of fabric on a striped background. It can be achieved low tech with graph paper and pencils if needed, using a simple paint program, Gimp alone, this is my process using Numbers and Gimp:
1. determine the desired shape, width, and height, checking that it also tiles properly
2. create a table with square cells the same width as the number of stitches in your design, twice its height; use an even cell size ie 20X20 pt
3. hide all odd-numbered rows from the top of the table down, the table will shrink from 20 rows to 10
4. draw your repeat
5. unhide all rows
6. copy and paste the table; double the cell pt height only to 40, making the repeat twice as long
7. mark corners or part of the edges with another color to make it easier for Gimp to identify them, select all and remove borders, grab the image with an added surrounding colorless border
8. open the screengrab in Gimp, use crop to content, fill colored squares with white, change the mode to indexed BW, scale the result to the appropriate size, in this case, 18X40, export png 
Cast on for EN or EON rib. Transfer all the main bed stitches down to the ribber. Extra stitches can be cast on and transferred in addition to the planned width of the repeats to create a border on either side of the designs. During patterning there will be stitches in work on both beds at intervals, so the pitch needs to be set to H while knitting. When the top of the piece is reached, transfer all ribber stitches to the main bed and bind off.
The first preselection row is knit from right to left in the contrast ground color.
With COR bring all the needles to be worked in the pattern color to B position on the top bed.
The knit carriage is set to slip in both directions. End needle selection is canceled. The ribber remains set to N/N for the duration. Knit to the left and begin changing colors every 2 rows.
The shape increases are created automatically, with eyelets at the edges where each stitch is picked up for the first time on the top bed. COL when the first needle is preselected in this case for the start of the next shape, transfer all previously formed design stitches on the main bed down to the ribber, continue knitting 
If any stitches are pushed all the way back or in mixed alignment during transfers, 
be sure to return them all to B position, not disturbing the needles already preselected for the next pattern row, 
repeat as needed. 
Because one color knits with every carriage pass while the other slips behind it not knitting for those 2 rows, the striped background fabric will become distorted depending on yarn and stitch size used, most likely particularly noticeable at the top and bottom edges of the piece.
