Geometric shapes on ribber fabrics with tuck stitches 2; knitting with 4 carriages

When switching between N/N and tuck/ tuck on the ribber it is not necessary to switch the tucking lever from its up position to the lower one. The ribber will knit every row when used in either of these settings It is possible to knit this type of fabric using color separations such as those seen for one type of DBJ where color one for each design row knits 2 rows, followed by color 2 for corresponding design row also knitting for 2 rows. Each color may be drawn and programmed once, followed in turn with elongation X2 on both punchcard and electronic machines. I prefer to work with the elongated images, believing it makes it easier for me to correct errors or knitting problems, should they occur. This color separation is the default on Passap. In Brother electronics, it would need to be hand done and programmed. It is best to start with simple shapes. This triangle series has been used in several of my previous posts. The chart shows the transitions in the process

Brother DBJ settings using tuck on either bed, not addressing hand needle selection on the ribber for the production of reversible fabrics. The yellow color highlights cam settings that require changing by hand for every other pair of knit rows and making the changes with each color change. With the exception of the bottom 2, the same settings were used in some of my brioche variation experiments. The resulting fabric, knit in reverse order from the chart (top setting down to first). The dropped stitches happened when I did not notice the ribber weight was resting on the floor, with no resulting weight on the fabric. There are single repeats of each motif. Two more possible DBJ variations

A full range of DBJ variations of the same repeat, including ones using slip stitch and shared in a previous post, executed in both one and 2 colors Passap knitters have the option of arrow keys and stitch type on the back bed that makes fabrics possible with ease that is daunting to reproduce on Brother machines. There is a category search on my blog that will lead to a collection of posts on the topic of knitting with 2 carriages selecting patterns.

I have often considered the possibility of using 2 coupled knit and rib carriages for some of my patterns but found it limited knit width because of carriage stops on the ribber bed, the unwillingness to have my ribber carriages fly off the bed, and the added limitation imposed when both carriages are selecting needles. Now that setting changes were required every 2 rows on the ribber I found a solution of sorts. It is one of those try at your own risk tips, but for me, it made several of the last swatches in brioche achievable far more quickly and accurately.
Brother ribbers have a stopper pin on each end that will not allow for the ribber carriage to move beyond a fixed point or to be removed easily, requiring tilting the carriage forward to do so I have long ago removed both of mine.  As in any knitting with pairs of carriages, when needle selection is happening from opposing sides, the turn marks need to be cleared on each side of the machine as the opposing carriage begins to move across the needle bed to avoid breaking the belt. I happen to be knitting present swatches on my orphaned 930, which still knits producing interesting sounds. It came with no carriages. I am actually using a knit carriage from a 910 and one from my 892E punchcard machine, with a magnet glued to the proper location facing the rear rail. I removed the stopper pins from either side of the ribber bed, placed lace extension rails on both sides as well as the color changer with all change buttons released as seen in this illustration. On the left, as the carriages move beyond the end of the needle bed, the return signal lever is tripped, making a characteristic noise. At that point, the turn mark on the left has been cleared, and it is safe to operate the carriages from the right toward the left
The right side of the machine is more problematic. The extension rail will store the knit carriage safely, but the ribber carriage has to move out enough so without its stop it would fall to the floor. My solution was to jerry-rig an extension at the appropriate height so the ribber carriage could slide out as much as needed while being supported. I was able to knit the hundreds of rows required for many swatches with no problem other than operator errors. Here the pair of carriages on the right are seen resting far enough off the machine to clear the belt, at an adequate height for them to slide off and on easily. At first, I secured the connecting arm to the connecting pin with an elastic “just in case”, but that proved unnecessary. 

I have been asked lately about the lili setting used in all my ribber carriage illustrations (center position). I tend to use that as a default to prevent errors and for consistent quality in my ribbed fabrics, especially if matching gauge ie in garment pieces or bands are needed. That said, for the carriage to travel far enough on the right in this setup, the slide lever had to be used on I. The plastic tray helped reach the appropriate height and made for easy slide off and on. There are a few minutes of maneuvering when setting up the first selected row. As always it is good to begin with familiar yarn and previous experience with double bed fabrics.

Some of my own operator errors are due to the fact that I still am not used to the fact that the 930 appears to revert to factory defaults with each new design entered, that I have to remember to switch from isolation to all over, that the image is reversed on the knit side like on punchcard machines unless the reverse key is used. I spent decades using the 910, where once the selections were made and once the pattern variation buttons were set, that became the default until buttons were changed for specific applications.

Double jacquard motifs in multiple styles, shapes, and sizes may be knit with variations in tuck settings. My post on a-return-to-brother-ribber-and-dbj-settings/   reviewed many of the possible cam configurations as well as working with multiple and even altered carriages. Passap machines have the added benefit of far more patterning than Brother on their back bed, the equivalent of the Japanese ribber. I am still obsessing over 3D folding effects, racked herringbone is back on my mind, as well as tuck ribber settings on Brother if one is willing to hand manipulate needle selection. I have been browsing through some of the directions in Susanna’s book again. For anyone unfamiliar with it, it was published first in 1986 and is the ultimate textbook on knitting fabrics on punchcard machines. It predated most electronics. Susanna continued to write for magazines and later addressed electronics in those articles and in her teaching lectures and workshops. This shows the cover of the paperback version. Over the years as many folks have written on DBJ, the separations have been named with some variations. In Susanna’s book, the original design is referred to as punchcard type A, the KRC separation built into Japanese machines is classified as Type B. This image shows the now-familiar series of triangles used in many of my blog posts on DBJ including at the start of this one. It is illustrated as the original repeat, then the separation is shown with either color represented by black squares. One of the peculiarities of this separation is the single-row color start. One may choose whether black squares or white squares knit first based on the pattern itself rather than simply on the convention in their specific machine brand. Color reverse in electronics is easy, but the function cannot be combined with KRC. It can easily happen if the separation is completed in software, prior to downloading the final repeat and knitting it. If a punchcard is used, simply exchange positions for each of the 2 colors in the color changer and follow the usual sequence. Designs must have an even number of rows. Susanna classifies the subsequent separations as C1 and C2.  Because each color in each row knits twice, there may be an odd number of rows in the initial design repeat. I am often asked as to why a type C1 or 2 separations would be a boon to fabrics made on Japanese machines. The options for new settings and resulting variations in the knit surfaces on both sides is increased many times over. These are some of Susanna’s suggestions for using the tuck setting in DBJ and begin to illustrate the point.

Tuck stitch meets thread lace repeats and vice versa

A recent share in the Facebook machine knitting group led to this blog post by its author <https://www.knittingmachinemuseum.com/single-post/Knitmaster-580-Electronic>

The inspiration fabric led to ideas for recreating it on a punchcard machine, and my own trip down that rabbit hole led me to think about the relationship between tuck stitch designs and thread lace ones.

Not all Brother knitting machine models were equipped with the capacity for thread lace. The 260 bulky happened to be one of those models, which were manufactured with 2 MC buttons seen in this illustration

Studio manuals refer to the fabric as punch lace. Early pattern books including ones for electronic machines provide a large range of pattern repeats for such fabrics and can be design sources for other knit stitches if one understands the structure being created. A quick “hack” to help keep the B position yarn from jumping out during knitting, taken during a different experiment In tuck stitch, the unpunched areas, white squares, or pixels represent loops created on non-selected needles, punched holes / black squares, or pixels represent knit stitches. In punch/ thread lace those white areas knit both thick and thin yarns together, while in punched holes/black square or pixel areas the thin yarn knits on the stocking stitch side of the fabric, with the thicker yarn floating behind it. Depending on fiber content, gauge, etc. the illusion of eyelets can be created. This is half of a Brother punchcard repeat, suitable for thread lace, reworked for knitting the design in tuck stitch. That is, in turn, doubled in length to allow for color or yarn value changes occurring every 2 rows. The resulting swatch is tested first in 2 colors to prove the repeat, then using clear serger thread as one of the 2 “colors” for a very different effect than blends that of both fabrics.

Looking at design sources for possible redesigns for the alternate knit fabric: published punch lace cards

published tuck stitch cards DIY a place to start is with simple color reverse punch lace to tuck test. Not suitable are any areas with lots of side by side white squares. In the bow solid lines those could be modified, most of the repeats in the colored swatch segments of the published charts are unsuitable.

Once the chosen repeat is isolated, the punchcard can be further edited for electronic knitting. Tuck to punch lace: any of these would be worth a test, some results may be very subtle.From punchcard repeat to electronic: strong black and white images that have punched holes represented as dots may be the hardest to process quickly in Gimp. It is best to isolate the single repeat. Some clean up of the gridded image may be required. Test the latter by tiling it. Color reverse the single it if that is the original goal, using the built-in function in electronics or punching black squares in cards.

Not to be forgotten: the easy variations for visualizing results with a few clicks of a mouse,

and an added source for both stitch types are slip stitch patterns in suitable configurations

Revisiting use of lace patterns Studio vs Brother machines

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

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

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

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

2013: While working out yet another HK to MK lace pattern, I sorted out the following method for using Studio simple lace on the electronic KM. It is a method that does not work on the Brother punchcard to produce the same fabric, however; on punchcard machines, as either carriage is moved to select from the opposite side of the bed, the card will not advance on the first pass, interrupting selection. I tried a swatch and got a very different lace design; depending on the starting pattern the results may be interesting (do not use elongation), but not the ones intended to match any original.
The knitting samples shown below were knit on a Brother 910. On electronic machines, as seen in previous posts on knitting with 2 carriages, the mylar (or otherwise programmed) repeat advances a row with each pass of the carriage, no matter on which side of the bed the pass originates. Dropped stitches are harder to repair in these fabrics than in patterns for multiple transfer lace (there knitting can be unraveled to the start of a sequence where 2 or more knit rows usually occur), so checking transfers, gate pegs, and adjusting stitch size and weights matter even more. There is no need to mirror the image horizontally if using a mylar; draw repeat as it is on punchcard, all variation buttons down
start knitting with KC (knit carriage) on left, Lace Carriage (LC) on Right program pattern double length on the first row the LC selects, the next row it will transfer; LC always makes 2 passes first toward the KC, then away from it, even if those 2 rows in repeat have no needle selection. It is then removed from the bed to be returned to the bed on the opposite side after the knit row with KC that follows. In summary:
KC knits a single row to the opposite side
*LC is placed back onto machine opposite the KC to make 2 passes, is removed.
KC follows with a single knit row to the opposite side*.  * to* steps are repeated
3 total carriage passes complete one row of knitting.
The preselection is repeated on the empty needles where stitches were just transferred.
The chart below shows actions and placement of carriages  This sample was knit beginning with lace carriage on left, as can be seen in marked areas, the alternating repeats have a different quality in the sets of transfers marked red vs green 
The successful swatch knit beginning with KC on the left, and LC on the right in the method described above April 2019 I attempted the same repeat on the 930 with img2track. I mirrored the repeat horizontally and elongated it X 2 prior to knitting it. The arrows in the chart indicate the movement of the lace carriage, beginning with the first preselection row from the left I had issues with the proper needles being selected (proofed also in fair isle), but with random stitches not being transferred. A switch in lace carriages, needle retainer bar, yarn, did not eliminate the problem. I finally had to perform some of the transfers by hand. This swatch also shows the joy of missed dropped stitches in lace knitting, the yarn used is a thin acrylic.    Different year (2023), even thinner yarn, with the image mirrored horizontally on the 930 using the method described above, the new knit proof of concept:  

An interesting method using 2  electronic lace carriages found on youtube. The repeat used in the video is a variation of the one used in my sample above, programmed using img2track. The repeat is mirrored prior to knitting, there are extra knit rows to allow LCs to continue the pattern from alternate sides. The machine being used appears to be a 930. The requirement for mirroring of any pattern may depend on the model of electronic KM used to knit the lace and whether the download appears as drawn on the purl or the knit side of the piece  A comparison of my repeat using a single LC and the Knitlabo pattern expansion  including memo options for use with 2 lace carriages

Ayab knitters before the latest software release: mirror repeat, tile repeat width across the number of stitches to match the number of needles to be used in your final piece. There will be no needle selection at the end of each sequence, signaling the need to release the LC, knit one row, and continue with LC brought to the opposite side. This is a very fussy knit. At several points, it is loops formed on previously empty needles that get transferred rather than full stitches. They love to get hung up on gate pegs. It took a significant amount of time to produce a proof of concept swatch. It is a lovely lace. Knitting it on a punchcard would give one the luxury of frequent pauses and markings to make for additional clues

KCOR knit one row to the left
LCOR 7 passes, release
KCOL knit one row to the right
LCOL 5 passes, release

KCOL knit one row to the right
In # 112 there are the standard pairs of rows between transfer segments. The punchcard pattern is composed of two 12-stitch matching vertical repeats, here 1 of the two halves is shown rotated counterclockwise. The additional extra knit rows in the Studio design have been eliminated. If knit as given this overall appearance will be different than that in the swatch pictured in the source. Brother machine knitters would need to track the midpoint location in the design, after the first 50 carriage passes, to place those extra knit rows, making six passes with the knit carriage rather than the standard 2. The 12X104 png, on a 930 with img2track remember to use the # 1 variation key  If one makes a choice or is required to repeat the width of the design to the number of needles used on the needle bed, it is easy to accidentally use the pencil in a paint program when working between windows. This test swatch clearly shows selection errors on a side edge only.   One way to check the repeat, handy when repeats are much larger or visually confusing: open the faulty one in Gimp, working in RGB mode, select by color and change black pixels to red, and make the white background color transparent by using Layer/Transparency/Color to Alpha. Open a new image, and carefully draw the design in repeat once more in the same location as in the first work window. Copy and paste the red pixels onto the black, revealing the missing pixels and the associated transfers on that edge.  Fill red pixels with black, return the image to BW indexed mode, and save the new PNG to knit the piece.  Redesigned for use on Brother machines with the LC operating from the left and the standard 2 knit rows between each design segment the 24X56 png knit mirrored horizontally on the 930, using a 2/18 wool comparing both versions a cousin version executed as a bulky knit

Geometric shapes on ribber fabrics with tuck stitches 1

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

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

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

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

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

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

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

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

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

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

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

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

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

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

2013: DIY design2017 crochet

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

Better stitch formation results with the different yarn used for the second color

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

2 color ribbed brioche stitch on Brother knitting machine 1

I have always found 2 or more color patterned brioche stitches executed in hand knitting as inspiring and complex challenges to admire, but have not been tempted to actually attempt to execute them in any way.
I have not knit on a Studio KM in more than a decade, have been asked whether this fabric is possible to produce on Studio/Knitmaster. The crucial difference between the 2 brands (Passap has its own universe) is the fact that Studio selects and knits with each pass. Needle pre-selection for clues as described here is not an option. Some Studio information from manuals on tuck knitting including settings for “English rib and Double English rib”:  tuck on Studio km.

This was my first Brother machine knit swatch result: Each of the 2 colors tucks for 2 rows and in turn, knits for 2 rows alternately. Settings are changed manually as shown below after every 2 rows knit, following each color change on the left. Making things a little easier: the top bed may be programmed on any machine, including punchcard models to avoid cam button changes in the knit carriage every 2 rows. With the main bed set to tuck <– —> throughout, black squares will knit for 2 rows, white squares will tuck, also for 2 rows. The first preselection row is toward the color changer. When no needles are selected on the top bed (white squares) the top bed will tuck every needle, the ribber is set to knit. When needles are selected on the top bed (black squares), the ribber is set to tuck in both directions. The ribber will tuck on every needle. Proof of concept: blue yarn is used on rows where main bed needles are selected (black squares). The crossed stitches at the top right begin to represent an effort to create surface shapes or designs on the fabric. They are created by crossing stitches 1X1, making certain the stitch creating the “shape” is carried to the front side of the fabric, the opposite stitch crossed so it is facing the knitter. I used KCI in this instance, the first needle on left in work on the ribber bed, last needle on right in work on the top bed. A border is created on the knit’s edges on the far right and left. The reverse side of the fabric:  Using a blank square on a knit row to help track 1X1 crossing patterns  Working the 24 stitch repeat using KCI; both first and last needles in work on the ribber bed. Due to operator error and forgetting to change ribber settings after a transfer row, I chose to stop knitting rather than attempt a pattern correction  Another attempt at cabling, 1X1 and 2X2. That white line in the bottom image on the right was caused by the color changer picking up and knitting both colors for part of the row before I noticed it. I got rid of the “wrong” color from the feeder and continued on. The wider 2X2 cables require “special handling” and eyelets are formed on columns aside from them after transfers are made. In 2022 I wrote a series of posts on visualizing cables including using the charts to anticipate ribber work and using custom printed needle tapes to facilitate the process. This chart illustrates cable crossings, which can be made in either direction. My own cables were made with the #4 stitch moving in front and over the #2 stitch. Keep in mind when direction matters, crosses will be mirrored on the knit side.
This particular repeat when used in 2 color brioche will move the cable stitches across a center vertical line in the same color as the stitches being crossed
For knitting using only one color, the machine is set with the main bed tucking on every needle in one direction, followed by knitting on every needle as it returns to the starting side, the ribber does the same but in the opposite direction. It is a circular tuck, also referred to as fisherman’s rib. The possible cam setting options: The cable crossings are made on an all knit row, following tape markings and always on needles marked in the chart.
Knitting the pattern in 2 colors requires ribber setting changes as described at the top of the post, and the first preselection row is made toward the color changer.
Knit rows are created after every needle is preselected, which happens for 2 consecutive rows. After the first row is knit, push back to B needles with stitches involved in the cable pattern, cross the specific ones, push any/ all needles B position needles out to E, and the second all knit row will be completed with the return of the carriages to the left.
Tension adjustments will likely be needed with every needle tucking on each bed for 2 rows. I had a loop hung up on a gate peg that was not noticed, which can be seen as a snag toward the bottom of the colored swatch segment. After the fact repairs in these stitches can be hard if even possible.
The concept swatch has varied test spacing between crossings.
Again, note that with this method crossings occur over a center column in the same color, not the contrast as in previous swatches. Plaiting is sometimes suggested as a way to imitate color changes in fisherman-rib. In this particular fabric, the result was quite muddy on both sides. The situation is different when working on single bed vertically striped fair isle designs. One of my ancient machine-knit demo FI swatches: On any knitting machine with every other punched hole, or electronic with black squares, or pixels locked on a single row, if the pattern is knit in FI, continuous columns of vertical color are created. If the goal is creating the continuous and unbroken vertical stripe 2 color pattern single bed, one must place like color on like color.
Because FI is essentially a slip stitch the fabric, it will have less stretch and is narrower and shorter than when knitting either yarn in stocking stitch.
Cables on the machine need to be transferred across fixed widths between needles, so there are distinct limits as to how far stitches will allow their movement in groups in either direction. Loosening the tension can often help. Sometimes it is possible to create extra slack by a variety of means, making moving the stitches easier.
I have found my own limit for this fabric was working with a 2X2 cross (it is possible to work moving single needles as well).
Adding to the complexity of single bed: proper needle selection for the next row knit needs to be restored prior to knitting it when using the FI setting, movement of stitches is mirrored on the knit side in the opposite direction of that viewed on the purl. Visualizing some possibilities as worked on the purl side to consider the knit side appearance mirroring is not enough the direction and appearance of the crossed stitches on the knit surface are reversed from that on the purl as well When working every needle rib it will take 4 rows of knitting with 2 color changes to produce the striping on a single row. R represents stitches on the ribber, K the stitches on the knit bedThis shows an instance where crossing the numbered stitches on the main bed with color changes every 2 rows, by default, lines up the same color on the same color. Stitches in the same color are formed in the in-between needles on the opposite bed.
Another way of looking at the 1X1 crossings on the top bed behind a single central fixed stitch on the ribber. The fabrics may be tested and knit in single colors as well. When working on the 2 color brioche crossings are made on a row where all stitches are the same color; 1X1 cables when made in this case, are forced apart by the tucked stitches between them on the opposite bed, in the alternate color, implied here by the white line Tuck stitches widen the fabric. As a result, the tucked knitting in this chart on the ribber (represented by the color yellow), forces the space between the knit stitches produced on the main bed (represented by the color green) apart, while stitches tucked on the ribber will create the gap between the stitches knit on the ribber, appearing on the reverse side of the fabric. The combinations create the appearance of single stitch vertical stripes.
This is an illustration of one possibility for programming reminders for tracking the location of cable crossings  Every needle ribs are generally knit at tighter tensions than when the same yarn is knit single bed. Too loose a tension in any tuck fabric causes problems with loops forming or knitting off properly, too tight will produce stitches that do not knit off properly. One limitation of crossing stitches here is the actual stitch size, which needs to be constrained to produce the fabric. Tiny stitches need to travel across fixed space. One by one crossing is manageable, 2 by 2 requires extra slack to make the transfers possible.

Adding some “give” to crossed stitches
1: the carriage has moved from left to right after the color change. All needles except for the four white squares in my design were preselected prior to the next row of knitting. The carriage now stays on the right
2: take note of the white tuck loops formed on the ribber on the previous pass from left to right
3: white tuck loops ( I chose center 3) are lifted up and off their respective needles and allowed to drop between the beds. This will allow the 4 white cable crossing stitches to have more slack. 
4: cross your cable in the intended direction
5: push cable stitch needles out to E
Knit from right to left, change color, continue in pattern
With some planning on longer pattern repeats it is possible to plan added clues to tracking rows on which the cables occur and their location on the needle bed. Repeats with very few marked areas merit testing in tile as any other repeat.
The charted repeat on the left below when tiled shows the area of a patterning error, on the right with the missing blank rows added the problem is shown to be resolved, the repeat is now 24 X 84. A proof of concept swatch: Planning for all over the brick layout of corrected repeat: The tiled repeat .png, 96 X 336, the single 24 X 168. More detailed charts of the 2 repeats, suitable for punchcard machines. Ayab knitters need to repeat the final motif across the width of the download in order to match the number of pixels to the number of stitches in use across the needle bed, using the single setting.

Knit and purl blocks to create folding fabric_ “pleats”

Knit and purl combinations may be executed in hand or machine knitting. Knit charts are generally planned and illustrated based on the fact that the same side of the fabric is always facing the knitter. Hand knitters have to accommodate for the fact that the work is turned over (unless knitting tubular) with every row worked, so plans would need to reverse knit for purl and vice versa if needed. For more ribbed, pleated/ folding fabrics please see Pleats: ribbed, folding fabrics , and Origami inspired 2: more pleats and fold using the ribber

The easiest way to produce this particular fabric on Brother machines would be to let your garter carriage do the walking and working. For those of us that do not have that option, there are transfer carriages, (I honestly have only used mine once, decades ago, will have to dig it out of mothballs) and transferring needles by hand. Pairs of identical stitch transfer tools may be used to move stitches from one bed to the other. If the goal is to produce a knit with tension as tight as possible, the latter can be problematic and result in dropped stitches, so testing the yarn and the mode of transfer should be part of swatch trials prior to committing to larger knit pieces.  I found moving stitches between beds one at a time for me was preferable and more reliable

The chart for the initial concept: The number of needles used for “pleats” is constant (7); 3 stitches move up (or down) in turn, indicated by arrows. After the first 3 are transferred, 3 more are now moved adjacent to the now remaining 4 stitches from the opposite bed in order to maintain a total of 7 on each bed, excluding any borders, in which stitch placement remains fixed.

cast on for every other needle rib after completing cast on rows, set up for pattern by transferring between beds*knit 6 rows, transfer between beds knit 6 rows, transfer again restoring original selections**repeat * to **; transfer to main bed, bind off. Swatch on KM prior to binding off If the goal is to retain the texture, it is best to knit using a yarn with “memory” such as wool, which may be steamed or blocked lightly while retaining the fabric’s quality. A rayon or cotton would flatten permanently if pressed. The photo shows both sides of my swatch, beginning on left with it slightly stretched with pins, relaxed in the center, and with a bit of vertical “tug” 
The fabric changes a bit when some stitches remain fixed on alternating beds, and the same sort of approach is used. My initial intent had been to transfer every 4 rows, but I actually did so after every 6 rows knit. Colors in the chart on right: Its numbers indicate the working needles on each of the 2 beds. The first 3 needles on either side are never transferred. Groups on either bed after transfers remain constant at 6 with the exception of the borders. The starting set up and the alternating one, repeated in turn throughout the knit. Note border stitch selection, constants in between still on the machine,  and my small test swatch. The fold on each side and the swing in the pattern appear crisper and better defined to me
What of horizontal folds? Transferring every stitch to and from the main bed manually is more than I am willing to deal with in addition to transfers for those blocks. I am also interested in the effect produced with the use of thicker yarn. This repeat is presently on my hand knitting needles, is suitable for electronics or punchcard machines. A single unit is 5 by 16 rows, the punchcard repeat is 24 X 16 X 3; 32 rows is a tad shy of enough rows for the punchcard to roll and advance properly, 36 rows in height is the recommended minimum. Knitting as tight as possible makes for a stiffer, crisper fabric. I decided there were things about this repeat I did not like, however, including the change in pattern at the folds

A complex published transfer lace to electronic repeat for download/ GIMP editing


Lace on the machine can render beautiful fabrics that closely resemble hand knitting, but programming very long repeats is a challenge both in placing every hole in the correct square in a punchcard and in programming individual pixels on a mylar or as pixels for download correctly. I found the “leaf lace” repeat below shared frequently on Pinterest and thought I would test the approach discussed in the post on using numbers and gimp to create images for electronic downloads. Because it is 16 stitches wide, it is not suitable for punchcard knitting, which requires a factor of (4, 6, 8, 12) and up to a 24 stitch maximum width.

The published pattern on the left is shown as shared on Pinterest. In turn, in was captured, opened in Gimp, and magnified. After a threshold adjustment, it was converted to a BW indexed, scaled to its 16X96 original stitch and row count, and then saved in 100% magnification result for the possible electronic download.

The published repeat is intended for use on Silver Reed knitting machines, for using it on Brother machines, the initial 2 blank rows are shifted to the top of the pattern design.
On the far left below is the first BW processed single repeat isolated from its source. To its right, it has been adjusted so the first row is a preselection row for the lace pattern, and the full repeat ends with blank rows (Brother KM characteristic). The latter in turn was saved as an image for download.
Since the leaves change direction in the way they lean, the spacing between each pattern swing in the repeat is actually 3 all blank rows, not the “standard” 2, including at the top.
The bottom half begins with the first row resulting in transfers to the left, while after the first 3 knit rows the transfers will begin to the right.  The plan was for me to use Ayab for knitting a proof of concept swatch.  In order to achieve that, the full repeat is first flipped horizontally (ayab will auto mirror it,  so starting with it this way it will be in the correct orientation when knitting). The mirrored repeat may be used in unaltered machines as is with LC operating from the right, with KC operating from the left (not possible in ayab without adjustments). The full repeat consists of 16+14+18+16+14+18= 96 passes of the lace carriage, for every 12 rows knit. My sample was programmed horizontally for 3 full repeats, the width of my planned swatch. I added one additional needle in work on each side, with the LC end needle selection canceled, allowing for the full pattern as programmed with a single stitch all knit border on either side A tightly twisted cotton yarn did best in terms of handling the multiple transfers and not resulting in split stitches or breaking. I had occasional selection errors, seen in the center panel at the top of each repeat (my common experience with the interface), but the repeat itself appears to be sound. Lace repeats that have even numbers of rows for both and LC transfer and knit ones are easy to follow. Punchcards are also easily annotated and if knitting is interrupted needle selection is easy to return to or restore if necessary. In electronics, there may not be any memo to indicate row #  location for each carriage pass in the pattern, or when to switch carriages. Because in this instance there are so many transfers (some of the multiple stitches) between knit rows and dropped stitches are best corrected as noticed during knitting if possible, I created a “cheat sheet” of sorts to help keep track of actions. Each block outlined in red here represents one full repeat, read from the bottom-up, with blue borders at the center and red at the end of each half sequence. A visual check at the end of each segment’s # of rows in the series is well worth it to prevent unnoticed runaway dropped stitches and large holes. A check-in box next to # could indicate the completion of transfers. and a number added manually in that same row for that sequence, record the row on which knitting was interrupted ie. stopping on row 8 out of 16 to fix dropped stitches would be a reminder that 8 more LC passes are required before the next visual check. 

9/23/18 In now have been experimenting on a 930, where each pass of the LC is actually tracked, akin to following numbers on a punchcard.  Built-in patterns also offer a memo window, which will alert the knitter as to when knit rows are due In testing the pattern with img2track I found the LC passes are still counted, but the memo window is absent upon download. I generated a chart in Mac Numbers, reads from the top-down, expanding on the one above. It illustrates the number of LC passes (left column) required to produce any significant length of fabric.  Patterns such as these are not for the faint of heart and require a friendly yarn. 2168 passes of the LC (33 full repeats, outlined in green; red line separates half repeats) are accompanied by 396 rows of “actual” knitting. In actual knitting, the pattern advances from row 1 to 96, and back to 1 again. A check-off list can be much simpler if one is desired. The numbers on left appear in the LC window in a 930, when reached 2 rows are knit with the KC. The numbers at the top reflect completed repeats. Boxes can be checked moving to the right as those rows are completed Another option is to download the pattern in img2track, and then enter memo information prior to knitting it. Two youtube videos that show how to enter memos in machine models that allow it, 930 included  https://www.youtube.com/watch?v=S0tXNT76v10    and  https://www.youtube.com/watch?v=nR8MheT5Bao. The number 2 may be entered after numbers on the left appear in the LC passes count window, and provide an easy guideline to follow. And this is what testing lace patterns can look like. In this instance, a tighter stitch tension, a bit of change in weight, and visually checking after each row of transfers brought me some success. This is not a stitch pattern that lends itself to easy “repairs”. A more successful sample knit also on the 930 using the shared repeat as given, knit in wool-silk 2/18

Altered patterning using bleach discharge on knits

These are random FI samples from my collection, most from my teaching days. None of them were ever intended for use in the finished product. They were knit to illustrate some of the possibilities for the different techniques using each of the cam button combinations. Some were knit during class demos. The colors made them easily identifiable as mine, knit using a personal yarn stash. The contrast helped identify how stitches were formed.
In this swatch, marking for measuring stitches per inch is done by leaving a needle out of work. The width between the resulting ladders should be checked at various points after the swatch is treated in the way you plan to treat (block) the finished fabric. Adding a third color per row would require altering the pattern to a color-separated slip stitch one, or one may add that color with duplicate stitching. The spots in this test are colored in with a permanent fabric marker. At the height of the art to wear movement one artist, in particular, was producing limited edition knitwear by knitting the same design in black and white, and in turn over-dyeing the white for different effects in each piece in the series. Eyelets at the bottom of the swatch are tension markings for the piece. The vertical line created by end needle selection (normally used in FI to avoid separation of colors et vertical edges) is interrupted in rows that are knit in only one color. Recommended maximum width for floats is usually 5 stitches.  How much the floats droop and cause potential “problems” on the purl side depend on fiber content. Sometimes such floats are intentionally created and worn on the outside of the garment as planned design features. The longer blue floats are seen below in the areas of the ladders where only the yellow is knitting, creating a wider span of the alternate color. These repeats are very simple. They are commonly associated with card #1 and card #2 in basic factory packs supplied with knitting machines purchases. Card #2 is reproducible by using card #1 elongated X2. A reminder: if using either repeat in pieces of garments ie baby leggings, etc. take note of which yarn feeder each color is in. Even if the repeat is correct and placed properly, the surface of the knit will appear different to the eye if the color placement is reversed in alternate pieces. The repeats may be used as backgrounds for a variety of other more complex fabrics in DIY designing. Here stainless 32 gauge wire is used as the second “color”, making the piece moldable and shape-retaining.   Color may be added or “taken away” as seen in the post on bleach discharge on knits Another factory-supplied punchcard is used. Thinner yarns in lighter colors may have noticeable bleed-through of darker colors traveling behind them, as seen on the left, not an issue with the thicker wool on the right. Forgetting to set the card to advance can result in vertical lines, which may alternately be planned as a design feature. The longer floats seem manageable in these yarns, there is a bit of hooking up on the bottom right. The yarn traveling up the swatch on the right is an alternative way to mark for gauge measurements. A previous post provides some information on float control.  Varying the colors, fiber content, and considering complementary borders is worth exploring thoroughly at the swatch level, before committing to a larger piece. Truly contrasting yarn used at the bottom and top of the area to be measured for row gauge makes the process easier. As attractive and quick as single bed FI can be, keep in mind that long pieces knit in yarns with “memory” such as wool, will tend to roll to the purl side vertically even after blocking, and certainly with wearing of pieces such as scarves or shawls.  Tone on tone chenille and all rayon, with “color reverse” by switching yarn positions in feeder less effective with a flat yarn as the alternative to the chenille Using the same card:  every needle, 4.5 mm electronic machine.  Transferring stitches to every other needle, odd needles in work on one side, even-numbered needles on other using worsted weight (2 needles in the center in work side by side.   The motif is now used twice as wide with every other needle in use across the fabric width It is possible to vary designs by using the 3 functions of the card reader: locked, normal rotation, and elongation. Designs with long vertical features tend to separate at the edges where the 2 colors meet. Lining the fabric with a fusible makes the knit lose stretch, but it may be an option for stabilization, float control, and offers an opportunity for mock quilting by inserting some stuffing under floats before it is ironed on. High contrast colors are best for sorting out how stitches are formed. Embroidery alters the “step ladder” effect outlining the shapes. Hooked-up floats are not just for float control; note puckering on the knit side where they have been hung up in groups.  These swatches were worked from the bottom up, starting with positive/ negative comparison, sorting out the possible placement of the ladder with the intent of adding ladder lace details. Cancel end needle selection because of needles out of work, but bring needles into D or E position to avoid separation of colors and/ or dropped stitches at side edges.  From the bottom up, transitioning from a ladder resulting from a single NOOW (needle out of work) to 2 NOOW, hooking up floats on opposite sides, ending in “lace” pattern alone  Combined with transfer lace  Hand techniques (in this case cables) can be combined with FI. In Brother, it helps to be familiar with the pattern, as needle selection may have to be manually restored after the technique is performed to stay in the correct pattern.
With cables: some punchcard repeats
With using a sewing machine: there is a vertical, single stitch line due to end needle selection in the contrast color formed on either side of any needle(s) out of work which provides a visual guide for altering the fabric. This swatch was knit with wide NOOW spaces, then sewing machine stitching joined the contrasting vertical lines to form a 2 color “fringe” on the knit side (left) and purl side (right)Variations with fibers for exploring surface textures: wool with raffia on the bottom, fishing line on top The same swatch continued on, using 3M elastic as the second color  The same repeat in a rayon chainette and wool, followed by some felting. The rayon “bubbles” more visibly when the wool creates the wider floats  reversing color positions
The punchcard is limited to varying the vertical repeat automatically in 3 ways: locking the card, normal rotation, and double length. Repeat width is fixed. Felting can produce interesting surfaces if one yarn is capable of being felted (green), and the other not (blue). The stitches knit with the latter will create puckers/ blisters. Since the knit will shrink in both width and height, the repeats here were used at double length. Note the added drooping of the blue floats on the purl side.  A punchcard can be further manipulated by masking areas with tape. It is not a good solution for production knitting, but adequate for testing out ideas before committing to punching a full, new card. The surface blisters here are much more dramatic. The green floats do not felt as much as in the previous swatch, and are considerably wider. On the right, far side you can see some of them were latched up, creating yet another design detail.
The reverse of both swatches shows the resulting difference in relative width.  The contrast using a factory-supplied punchcard pattern with short floats, also felted. The fringe is created by ending on one side (in this case on the right) with a group of needles out of work and the outermost 2 needles in work, essentially producing a large “ladder”.  Decreases and increases on needles close to the edge of the knit were brought in and out of work to create the “zig-zag”. The two edge stitches of the ladder may be trimmed before felting. The knit side is shown on the left, the purl side on the right, no clearly visible, separate floats, its surface is fairly flat.

Quilting using Ayab software


My last post reviewing the quilting on the machine topic so far. Ayab does not allow for the first preselection row to be made from right to left. In any fabric where preselection needs to occur from that direction, with pattern instructions written with that requirement, in order to match the fabric the solution lies in shifting the last row of the repeat down to the first. If you are working on an odd number of needles and set up matters, pay attention as to whether the program places the extra needle on the right or the left of 0 before you commit to placement on your needle bed, the software is not consistent in this. Here the odd # is placed on the left, in a later swatch on the right. From Adrienne Hunter the tip “I think you are expecting that the odd number will always be on the left. But that’s not it, the rule is that the larger number will be on the left, which may be even or odd. ”

Ayab settings: 
I began with this partial repeat from an older post

To avoid any confusion with which KC (Knit Carriage) slip buttons to push, simply push in both. The selected needles that should knit in slip stitch will knit, and the ones that should slip (not selected) will slip. Knitting starts COL, prep the interface, travel to right. With COR proceed to left. Machine can be set to knit those first 2 rows, or to slip both beds if you do not wish to have the extra 2 knit rows. Now with COL set main bed to slip <–  –>, ribber to slip <–

My first repeat for a “square” pocket was wrong. The total number of rows in height needs to be an even one. It takes 2 passes of the carriages to complete one circular row. The first repeat below is 17 rows high; so I got as far as one series of pockets followed by mis patterning that was the fault of the design, not the program. The software gives one the opportunity to easily check for stitch and row counts. Though I loaded images 60 stitches in width, my samples are knit 40 stitches widethe amended repeat, now 16 rows in height 

I had a problem when I first paused to stuff pockets with the software advancing a row even though I was outside the left mark, but no issues after I restarted the process and continued. Because the pockets are knitting stitches separately on each bed except for where shapes are joined, the resulting knit approaches stocking stitch qualities and tension settings. It lacks the stretch of every needle rib, where twice as many needles are in work. The joins on the knit side (L) nearly disappear unless the fabric is stretched, while joins on the purl side (R) are more visible. 

A “diamond” 12 stitch repeat as it would appear across the bottom of a punch card with the option for first preselection from either side, followed by appropriate cam settingsThe repeat adjusted for preselection from left, illustrating row shift on right
The repeat adjusted for knitting across an Ayab 60 stitch swatchThe bottom of swatch, with absent pockets, shows what happens if wrong slip/knit combinations are in use. Knit side is shown on left, purl side on right, with a bit of cotton ball “stuffing” poking through  
While trying to work with the circular and other settings I found an easier way to achieve one color quilting, still working with that “diamond” from my early post 

I use GIMP to create most of my images for download to either the Passap or now also the 910. In order for the elongation not to be muddy with an image outline in multiple colors, or to cleanly tile it, the image will need to be converted. To draw or paint, begin in RBG mode, then change image to BW palette for scaling or tiling 
 make certain the number you wish to remain constant is highlighted
click on “chain” to break aspect ratio
change the second value to desired one click on scale, here is the single repeat, without the necessary last row shiftto tile the image across the width of your swatch make certain the value you want to remain constant is highlighted 
“break the chain”change width to stitch count of your swatch

the tiled image will appear in a different part of your screen, it will be the repeat usable for the first preselect row from right to left. More on using GIMP.

For use with ayab with a repeat that is already tiled but needs “correction”, using snap to grid, dot to dot, copy and paste all but last row onto a new image at the top of a new canvas with the same pixel width and height. Then copy and paste the last row from the above tiling to the first, blank row of the new image. You may also simply work on the original image if you are comfortable with moving the larger cropped image around, pasting it in place at the top, and then editing the first row by hand.  Finish with “export as” in your preferred format for download The smaller diamond would also be workable, but resulting shapes would be very small. The initial, unaltered tiling:for use with Ayab:
Ayab setting is for “single machine type”. The carriage settings: opposite part buttons, right on KC, left on ribber, are set after the first 2 preselection passes, with COL

the resulting elongated diamond fabric, knit and purl sides respectively

Thickening the outlines of the “diamond” varies the joined outlines; solid geometric  shapes may also be created and used as seen in other posts. I like to work with same or similar shapes to understand what the different settings do to their knit structure and scale

Working in more than one color: using the color separated repeat double height. The first chart below illustrates it as it would appear on the bottom of a punchcard. Here first preselection row would need to happen moving from right to left, toward the color changer, with subsequent color changes every 2 rows  
adjusted repeat/ top row shift to bottom for use with Ayab’s preselection from left This fabric requires changing ribber settings manually every 2 rows, thus creating a solid color back. Set the ribber to slip /levers up when most needles are selected on the top bed, set ribber to knit / levers down  in both directions when a few needles are selected on the top bed. The latter selection forms the “stitching” lines on “quilt”. The first color to knit after preselection toward the color changer knits the black squares on rows 2 and 3 in the chart above, so it will create the dominant color in front of the fabric, the second color change will knit the background / white squares on rows 4 and 5 above, and seal the edges of the diamond / black squares 
Reminders: no matter what stitch type, if you forget to select proper cam buttons after N/N settings you will only get plain knitting (stripes at bottom of my swatch). If you are working on a Mac make certain to set your energy saving preferences to insure it stays “awake” for the duration of your knitting time. I happened to knit my samples with cam button set to KC II. KC I is the better setting, giving a slightly different seal along the edge away from the color changer. 

What of using the ayab circular setting and letting the software do some of the “work” for you? The setting was developed for tubular fair isle, so the main bed  with slip stitch <–  –>  knits alternating colors. When the one color knits on the main bed, it skips and forms floats in front of needles not selected for that color. The process is repeated with each color change. There will be a pair of  floats on the inside of the knit for each completed design row. For some how-tos to achieve color separations involved, and more info on tubular knits including Passap techniques please see previous post

The goal is to had been to use the ayab circular setting to produce quilted fabrics, joined at intervals rather than as an open tube with a different pattern on each €œside€.  When attempting to utilize anything “off label” for a use other than intended, lots of trial and error can be involved. Ultimately the choice needs to be made as to whether the final technique is worth using simply because you can. I habitually double check my settings and fabrics at least once, a day or more after I knit my samples and post. The work in progress posts actually show some of the editing as it happens, with corrections and mistakes included. The heading goes away when I think I am done with the topic. A day after my pink and white adventure I tried to reproduce the fabric with absolutely no success. This was as close as I got, with different carriage cam settings, the knit side is shown. 

After quite some time and a collection of expletives in 2 languages it appears the solution to my inability to produce the fabric is because the ayab setting I used for knitting it was not the circular one. After a software patterning error and a program restart, I apparently selected ribber rather than circular machine type and proceeded happily to success. To produce the fabric in my re do: the ribber “machine type” setting was chosen 

the green yarn is thinner than the pink, so the bleed through of the white on the reverse side is greater. The remaining information applies. My first samples using a single stitch outline, length X 2 for the €œdiamond€ were a disaster in terms of stitches falling off, the fabric being a squishy, shortened mess.

Back to the drawing board: I thickened up the outline of the shapes, grading up and down in 2 rows in height sequences, needed for getting to and from the color changerI chose to continue to test on a narrower repeat. An added consideration: in knitting fair isle, the first and last needle on each side is normally selected whether by using change knob on KC I in 910, or adjusting knit under carriage in punchcard machines. One can program black squares on either side of the full pattern repeat for the width of the fabric to insure that any number of edge stitches knit every row on each side. Working on a smaller repeat, now 47 X 24note: the odd # and even number needle positions for this new repeat are in reverse order from the one at the top of this post. Here the odd # is placed to the right of 0, not the left
If for any reason you choose to work in color reverse, the black border on each side will be lost.The amended repeat to keep that knit border (black squares/ pixels filled in; this was my working repeat It takes a few tries to sort out what may work. These were my first effort switching ribber settings around until I reached  creating pockets.The color choice needs to be made re solid color for backing and sealed areas of the fabric; for me it was the pink. This is where things get a little fiddly. The fabric settings once the first design row is preselected: KC is set to slip in both directions throughout (remember to change main bed to slip if preselection row have been with KC set to knit). I began with pink for my “sealing” stitches/ solid backing color.

After return to left, change color (white),  no stitches are knit on the ribber, only on main bed

here the floats become increasingly apparent the ribber  now dropped a notch on the right side 
stuffing pockets with cotton balls the ribber is returned to up position, knitting continues 

A: setting operator error creating solid color row. B: same, ribber not set to slip in both directions, resulting in white joining all selected needle. C: stuffed pockets, tending to make fabric wider and shorter   A, B: extra sealing rows (2 in white). C: stuffed pockets and a bit of peek through cotton. D: points to bleed through backing color of white floats on the inside of the pocketsA helpful tune: pink down, white up in reference to right ribber slip lever.

The question now follows: which color separation does Ayab perform automatically for DBJ?

 

Revisiting machine knit “quilting”

In 2013 I shared my first post on the topic, covering single bed quilting as a hand technique, with the aid of a punchcard to pre-select needles only, and with an intro to a simple ribber repeat in a single color. It was followed by a post explaining the color separation for 2 color quilted fabrics. It is also possible to use an altered knit carriage to knit rows on the main bed only while leaving the couple carriages on the left instead of changing ribber settings from slip to knit and back with color changes, see post on ribber-fabrics-produced-with-2-knit-carriages-selecting-needles/

one color experiments using monofilament 

In my swatches below, the red stars mark the spots where one fabric surface separates from the other. All use 2 color patterning, with a single color only appearing on the reverse side. In Brother machines to achieve this result, the ribber settings are changed manually every 2 rows. The ribber is set to knit when carrying the backing color, which is also creates the “stitching/ joining” sections, while it is set to slip when the color creating the pockets is worked. The settings on the illustration on the left create the foreground color pockets, and the ribber slips for 2 rows. The settings on the right will knit every row on the ribber. Two rows of each color are knitted alternately, the same as in DBJ. Since there are as many “blister” rows as there are rib rows, the blister/ pocket design will lie flat against the backing. If the goal is a lined Jacquard, the yarn tension must be evenly balanced to produce a fabric that lies flat. The texturing of the quilted surface is produced with uneven tension, knitting more loosely on the main bed.  The looser surface may be left as is, or wadding may be inserted between the beds as knitting progresses while dropping the ribber partway. Commercial versions of these fabrics are sometimes referred to with the terms eightlock or interlock, and double jersey. The punchcard instructions for the first swatch, from Brother Ribber Techniques Book,

Passap Technique 181

here the large areas are obviously “stuffed”

Pockets  may result as a part of  any larger, DBJ design, when monofilament or thinner threads may be used for the second color

Possible problem areas: stitches may be dropped along areas where fabric is joined (A), sealing side edges (C) will keep them from separating (B). The end needle on each bed must knit the opposite selection as its neighbors in order to close the selvages. The last needle at the side opposite the color changer may require pushing needles to E manually if not selected by the KM at regular intervals. 

Blister fabrics and pintucks are cousins.
Quilted fabrics are sometimes referred to as “single blister”. Both rely on one group of stitches knitting more rows than another and can occur both in a single color, or multiple colors. The ribber slips while the main bed knits X number of rows in pattern, and pleats/ pockets are created, eventually sealed by knit stitches on both beds. The number of rows for which this action may be taken in Brother machines is far more limited than in Passap, where the strippers help keep the fabric in place.
Single-color pintucks/ blisters began to be addressed in my post, which reviewed Brother ribber techniques suggestions. A multiple-row blister sample executed on Passap, in turn, programmed from an ancient DUO 80 magazine, eliminating hand selection on the back bed, and programming it in terms of black and white squares on the front bed.

its reverse side 
My E 6000 manual is annotated extensively, and my scribbles make a good argument for keeping better notes. I immersed myself in learning the machine when first purchased it.
Knitting techniques 250-255: when using even numbers the pin tucks are formed on the back bed on the needles which are opposite those with pushers selected down and according to black squares on the card. The corresponding odd number techniques select pushers down according to white squares on the card.  

The technique for solid color backing, tubular FI illustrated in the manual, is a workaround to create “quilting” “automatically”. A bit of translation and a different setup from my working notes are offered after the scanned image. The circular setting in Ayab software performs the same automatic color separation. With this arrangement, pouches will be formed on the white squares of the card. If you think in terms of the colors of the squares, then it is not important which color is determined as the background color by the console.
The setup may be different in your copy of the manual.
Knitting four consecutive rows with either color reverse the position of the colors in the pattern.
Every 4 passes of the locks complete one design row.
Reversing the BX <– pusher selection (manually, on the right, prior to color change), will reverse the areas quilted.
The first pushers on both left and right are aligned in the opposite position to rest.
Floats are created between the layers by the color not knitting on the back bed, and the altered pusher position will keep them from jumping off. Depending on the size of the pockets you may want 2 pushers in that position rather than one. Always swatch before you commit to a large piece of knitting.
The identical design methods as those offered for Japanese machines and the associated fabrics may be reproduced by entering the separations as a pattern and then in turn entering technique 129. The PDF suggests a method for using Japanese designs as drawn on the punchcard knitting machine in an E6000.
My scribbles from my Passap manual. The console and manual recommendations are only guidelines.
Any and all technique lock settings may be altered to suit planned fabric, and if the machine offers beeps and reminders for the factory program, simply disregard them.

It is recommended that pushers not in use for any pattern be kept in the rail.

Double bed work requires at least 80 stitches by 100 rows for gauge testing for finished garments. Any machine: for blankets or warm jackets, the pockets may be filled with padding every X # of rows, and the front bed may be dropped to make this easier. Monofilament and /or fine wire may produce structures that have objects dropped into pockets i.e. marbles, sequins, sponges that will expand into space when wet with fluid, etc.

While working on a later post on knitting this fabric using Ayab software in a hacked 910, I found using a simple single pixel height per row diamond shape outline, elongating it X 2, and working in the circular setting produced the single color quilted fabric with no other fuss ie. a color separation. Below is the working repeat for use with the first preselection row from right to left, knit with the right slip button on the main bed, and the left slip button on the ribber throughout. The same settings and approach should work in punchcard Brother machines.
