Modifying repeats in tuck stitch experiments

When color changes are planned for every pair of rows or multiples of two, i.e., 4, 6, 8, etc., color changers facilitate the process.
Preselection, if the color in the first pair of design rows matches, is made from right to left. The stitch-in-work count need not always match, just the color selection.
Often, thread lace published designs have tuck stitch segments separated by at least one or two rows of all knit stitches, making it easy to plan and track color changes.
This tuck stitch design is published on page 38.  The tuck stitch groups are knit off in the same color when using 2 colors, forming a clear vertical line on the knit side.
An obvious first rotation could be using this repeat, with changes every 4 rows, with the first preselection row toward the left,
24X24.     No published design that I know of includes the placement of needles out of work (NOOW) to produce ladders in a tuck lace version. This chart continues with color changes every 4 rows, and green columns represent the NOOW placements, with 4 rows of knit stitches, black cells, followed vertically by alternating 4 rows of tuck stitch, blank cells.  Electronic machines offer the ability to program what one wants to knit and where.
The first test, 46X24, includes knit stitch columns on each side, is mirrored on the 930, and knit on 45 stitches. The side edges form vertical knit borders, 2 stitches on one side, 3 on the other, with an opportunity ot evaluate whether the extra knit stitch beside the ladder is worth adding, perhaps even in larger numbers. The setup on the machine: With the first row shifted up to the top, 24X24, the first preselection row is still made from right to left.
A new chart, also planning to add NOOW indicated by light blue columns. The evolution of the repeat in black and white:
A: the original design
B: with the shifted row
C: the programmed repeat for use on the 930, with knit stitch borders on both sides.

In this method, each color tucks for 3 rows, and on the fourth pass, knits the tuck loops and the held stitch. There are no apparent errors in the swatch after the needle with the culprit latch was replaced.
Color changes are every 4 rows. The fact that each color tucks for 3 rows and knits off in the same shade creates small horizontal lines but the shapes are separated vertically, with no continuous lines of solid color as in the first all-blue swatch with the unaltered repeat.
The patterning errors, not noticed during knitting, needed some troubleshooting, and were narrowed down to a sticky needle latch. There are vertical all-knit borders in both samples, 2 stitches wide on one side, 3 on the other.
The change in landscape when a third color is added, with a planned 3-stitch knit border on either side, programmed on 48 stitches, knit on 47.

Tuck stitch fabrics with added needles out of work are often referred to as a tuck lace. Some previous posts on such design repeats:

More on brioche, geometric shapes knit with tuck setting

Most tuck patterning is based on designs with lots of black pixels serving as background for white pixels in bars that are generally a single cell in width, and on Japanese machines, no more than 4 rows in height, followed by black cells above them to knit tuck loops and the last knit stitch in the same location together.
One random sample, 24X48, to match a repeat suitable for a punch card. Several fabrics visually break that pattern and are knittable.
Such instances may be found in single-bed “floatless” FI, aka mosaics and mazes.
This is a large-scale sample, 40X40.To knit it using the tuck stitch setting, the original design is color separated by color-inverting every other row in the original image, starting with row 2, and then doubling the result in height to 40X80. To knit as a tuck or slip stitch pattern, the last PNG was again color-inverted,  programmed, and test-knit on 80 stitches, and for 120 rows.
The pattern section of the swatch, knit using the tuck setting, measures 11.5 X 9.75 inches and is reversible. When working in every needle rib, if the ribber is set to knit every row, the stitches on the ribber will help anchor tuck loops formed on the top bed, which makes tucking many side-by-side stitches there, again meeting limitations in terms of the number of rows in Japanese models, dependent on yarns and design choices.
As in the case of single bed mosaic/ maze work, when using more than one color, each design row repeat must be repeated twice, and is knit with color changes every two rows.
The swatches are knit with the end needle selection on to ensure end stitches are knit on both beds; the result is the beaded appearance in the side edges.
The first and last needles in work are on the ribber, with it set to half pitch.
These fabrics have good drape and are very stretchy, so cast-ons and bind-offs in the final pieces must be considered.
A recent FB question on brioche knitting to achieve horizontal lines of color rather than vertical, prompted a return to sampling with a new repeat, 18X24. The process is fully automatic, while the brioche with designs formed by shifting vertical lines of color to create shapes evoking the far more complex hand-knit versions requires hand transfers as often as every fourth row.
In horizontal patterning, each color is present on each needle with each carriage pass, whether as a knit stitch or a tuck loop, so loop and stitch colors will mix.
The work on the machine: after the first carriage pass is completed with either color moving from left to right, needles that are pre-selected forward will knit stitches, the ones in the B position will form tuck loops.   After the carriages move to the left, repeating the same selections and preselecting for the next carriage pass, the color is again present in every needle hook as a stitch or a tuck loop.The needles that are preselected forward to form knit stitches with the next carriage pass now hold the last stitch knit in the previously used second color, and 2 tuck loops from the recent, dictating limits on the yarn thickness used. The pattern was test-knit on 36 stitches.Introducing small diamond shapes in a brick arrangement, separated by solid color stripes, 16X80. The test was knit on 42 stitches.
Those dropped stitches, noticeable on the bottom right, were missed as can happen when knitting ribbed fabrics, where they may not be noticed until after several inches of work on the machine, or even after completion of the piece.  This left me wondering about other geometric designs and how to make the process easier in DIY design development.
This 16X18 design was used frequently in previous posts on color separations.In color separation for mazes/mosaics, alternate rows beginning with row 2 are color inverted, then the result is doubled in height to 16X36, twice the height of the original.   The repeat was tested on 32 stitches. To color-separate for DBJ, where each color in each design row knits twice, multiply the original X2 in height to 16X36, color invert every other row beginning with row 2, and multiply the result by 2, to 16X72, 4 times the height of the original. Seeking a visual break from the yellow, the blue was the third yarn tried to achieve a predictable stitch formation.
The same tension was used as in the red and yellow swatch, tested on the same number of stitches, 32, with a resulting pattern area 1.25 inches wider.
The design is more recognizable, and the separation method, automated by some download programs for 3 or more colors, may be worth a test run.

Returning to the skull shape slightly different from the one first explored in the 2022 post, planning to decrease the height of the overall repeat by color separating as for a mosaic or maze, the 58X82 starting PNGwith every other row beginning with row 2, color-inverted 58X82,  with rows of pixels added at the top and sides for more pattern surrounding the skull shape,70X90,  doubled in height to 70X180, sampled on 70 stitches produced a more rounded skull than the repeat sampled in DBJ. The DBJ separation would begin with the initial 58X82 file doubled in height to 58X164 before beginning the color inversions. Some of the related posts, in reverse chronological order

More fabrics with knit bed tuck patterning 2

Tuck lace knits require specific needle arrangements to form properly.
Tucking on needles intended to be empty will keep building up loops in fixed locations, potentially resulting in interesting carriage jams and yarn formations.
End needle selection is canceled.
The following are typical published illustrations as found in punch card volumes.
The same repeats intended for tuck lace may be used in double bed work.
Cast on every needle, transfer stitches in the OOW locations down to the ribber, and proceed in pattern.
The reverse process, using patterns already established for double-bed work, can be tried for a more open single-bed tuck-lace knit.
Depending on the electronic machine model and the download software used, the pixel repeat match to the published punch cards may need mirroring horizontally.
Air knitting can be useful in determining needles to be taken out of work; they will not be selected in the same positions continually. Cast on every other needle, i.e., by chaining on every needle and dropping the chains in OOW needle locations, cancel end needle selection.
If the goal is to evaluate what happens with frequent color changes, a start can be made with the first preselection row from right to left toward it.
An alternative way to plan the designs is to repeat/ mark the same selections once more aside them in all blank needles out of work columns, making their use independent of needle placements on the machine bed. The smallest, altered repeat, tested every other needle on 48 stitches, and produces a fairly dense, reversible knit. Any of the following arrangements can be planned for asymmetrical or random arrangements of all components as well, once the stitch structure is understood.
Returning to one of the repeats shared in the post on more fabrics with knit bed tuck patterning (1), which originated with the starting published design, 24X48,   then modified by adding blank cell vertical columns for an isolated 10X24 repeat, the related chart and PNG. A chart with the intended transfers down to the ribber represented by magenta cells, and the tested 63X48 PNG.  The yarn used is Merino wool. This is a modified needle count and arrangement with tuck columns 7 stitches wide to accommodate ladders represented by cyan cells in the chart; extra black cells were added for knit stitch side edges. The 62X48 test PNG, used in the top swatch below. The repeat, adjusted for 5 stitch tuck columns, and its 61X48 PNG, knit-tested in the bottom of the image.  A repeat knit test of both, showing the transition in the needle arrangements in a different colorway. This yarn is a 2/18 alpaca and silk blend.
The part of the swatch with stitches transferred to the ribber measures 2+ inches wider than the ladder sample following it, 9.5 inches, as opposed to 7.25.Previous blog posts with added single-bed-related techniques and repeats:

One repeat explored in many ways 2, single bed tuck stitch

The spreadsheet plan, 24X56 cells,  with colors edited to yield a brick repeat suitable for tuck stitch, 24X112test knit on 48 stitches using a 2/8 wool. Adjustments were made in the spreadsheet to increase the tuck texture while blunting the diamond shape, configured for a brick repeat, 24X120. Larger repeats require proportionately larger swatches to visualize the effects. This version of the design was test-knit on 72 stitches. My available yarns had to be plied in pairs to try to match the effect when using the 2/8 thickness wool. Adding stripes of all knit third color, for a 24X144 repeat, knit-tested on 68 stitches. The yarns were plied to mimic the results obtained in the 2/8 wool swatch, which led to some problems with singles jumping to the adjacent space in the color changer or mating with other yarns in the tension areas of the yarn mast. For long pieces, it may be worth twisting the yarns onto a new cone or ball, or using one of the accessories, purchased or assembled from containers found in the studio, that will allow for feeding the yarn from one cone through the center of and with the yarn from a second cone (or more). The yarns used in the bottom third of the swatch came to their end, so there is a slight difference in texture and size as a new pair was chosen with a goal of retaining the same degree of texture if possible. Pushing the limit, with double strands tucking for 3 rows rather than 2, the shape at the center of the tuck stitch areas now has straight vertical edges, 24X136,    knit tested on to 70 stitches with a slight pattern center shift. Double strands were used in this case, tucking for 3 rows, with some loops getting caught on gate pegs as seen in the image on the right.
Spots with loops not always perfectly knitting off are harder to see on the purl side during knitting.
Four threads in needle hooks is often the limit on 4.5 mm machines for tuck stitch, unless the yarns used are very thin.
Pins placed temporary folds on the knit side led to yet another repeat and test swatch. The last adaptation, 24X80, was knit on 70 stitches.  The light-colored yarn refused to knit tuck for 3 consecutive rows, with loops not knitting off properly, and getting frequently hung up on gate pegs.  Switching yarns and colors led to smoother knitting. 

One repeat explored in many ways

Questions as to how to design for specific knit structures or how to use randomly found repeats appropriately turn up regularly in forums.
A review of punch card repeats found in downloadable volumes, which provides clues as to the suitability of random finds for different techniques, can be found in  Punch cards to electronics: book symbols and samples.
This post began with a random published find from an electronic pattern book. The initial goal was simply to evaluate and play with the design, and then it evolved into a project growing in size as more ideas were sparked for added swatches. the match, 24X3648X72 is potentially usable for
1: knitting as FI, with a wide maximum float of 9 stitches, which would merit control
2: thread lace, both yarns knit white pixels, the thin yarn forms the stitch on the knit side, the thicker yarn floats behind it
3: knit weaving, deciding whether to manipulate the long floats that are formed intermittently
4: tuck stitch, must be color inverted, white pixels form tuck loops for 1, 2, and 3 rows in various spots in the design.DIY editing of the first repeat, seeking uniformity, eliminating rows, and shifting pixels for added possibilities.  24X24in full repeat X2, 48X48doubled in height, 48X96 color inverted, 48X96potentially knittable doubled in height once more, test with thin yarn, 48X192tested single bed for 60 rows, an obvious change in texture and aspect ratio. Single bed using the original, color-inverted file, 48X72. The yarn is a 2/20 wool; the resulting stitches are open enough to allow the dark bleeding through from the background to influence the appearance of its color. The swatch measures 7.25 inches in width.  Double bed
The knit carriage is set to tuck in both directions, the ribber to knit in both for what is often called pintuck or punch tuck rib. The knit lies flat and is “reversible”. Using the same number of stitches and knit tension as the above, this swatch measures 10.75 inches.  With the tuck stitch file easily color-reversed on the electronic, the knit carriage set to slip in both directions, and the ribber to knit in one, slip in the other, the density and width of the resulting knit change significantly.
Punchcard knitters would need to punch a second card.
Blisters are formed on the knit side while stitches on the ribber become elongated when slipped.
As the knit carriage returns to the left and skips needles, floats are formed to a max of 9 needle spaces, and eventually form pockets in the white pixel areas. As the ribber knits in one direction, it slips in the other, and stitches become elongated until they knit once more. The yarn needs to be able to tolerate being held for the necessary number of rows without breaking. The swatch measures just under 5 inches in width, although worked on the same number of needles as the tuck samples.
Some of the color difference is due to a change in natural light, but also to less bleed-through of the background as a result of the fabric density. As double bed knitters know, several inches of knitting happen before you can crawl under the machine or get creative with a mirror and/ or + lighting, to see whether you are actually knitting the intended pattern. This design, using the same yellow yarn with the added blue yarn of the same weight, and the same carriage tensions as for other double bed samples, made it hard to see whether anything but stripes was being produced while on the machine. The bottom of the swatch was knit with striper backing, the ribber set to N/N, and measures 6.5 inches in width. The top was knit with birdseye backing, using both lili buttons, the ribber set to slip in both directions, and measures 5.75 inches in width.
The color placement for background or design can simply be chosen by which color knits first, so either the color-reversed or the original repeat may be programmed. Original 48X72Single bed
This swatch was knit using the thread lace setting, and two slippery yarns, a rayon and a nylon thread of an unknown brand. Serger monofilament is an option, but my supply is multiple decades old and broke easily halfway up the first repeat. Testing large swatches and blocking them in the same manner as the finished piece would serve as guides in making choices.
End selection needle is canceled, but if end needles are brought out to D as part of the pattern design, they need to be pushed back to the B position manually before the next row is knit.
Width comparison does not apply, since the tension required was double that used in the other swatches.
There are less common applications when choosing designs. For example, the same repeat was tested to create a single-bed lace transfer design, with a single row knit after the transfers in each design row have been completed. It finally took using a 4th yarn to get the stitches to knit properly, unlikely something I would knit in a large piece, but it helps to understand what happens with reversals of directions in the mesh.  An explanation of the technique, with added swatch samples and designs, may be found in the post Unconventional uses for punchcards 2: thread lace cards for “filet” mesh 
The slip stitch double bed blister knit was shown previously, using the starting 48X72 repeat. Here is a double bed version, using the plaiting feeder and with the knit carriage set for thread lace. The results differ with placing the yarns in alternative positions, and both swatches measure 9.75 inches in width.

 

 

 

Pinterest inspirations vs implementation, tuck and lace combos 2

This post will be a growing companion to Pinterest inspirations vs implementation, tuck and lace combos 1, addressing designing repeats for automation of such designs on electronic machines.
Lace transfers made in the same direction will lead to the knit biasing in that direction.
Reversing the direction of the transfers at intervals will balance some of that bias.
In the post on A return to lace with automated patterning, adding color striping, the LC transfers were charted moving diagonally as well,   achieving this result.  In this inspiration source, the transfers are made in rectangular blocks.  Assigning symbols and BW fill to cells in turn,  expanding the repeat following arrow markings pointing to the LC selections and transfers in the correct directions.  The single repeat, 20X42.   In the bottom design rows 1-13, the LC makes 2 passes followed by 2 rows knit, in the top 14-41 rows, 4 LC passes are followed by 2 rows knit.
The test knit on 51 stitches.  The side knit borders are 2 and 3 stitches, respectively. Next to the 2-stitch one, the eyelets are slightly compressed, appearing smaller than those next to the 3-stitch border.
There are charts worked out for fully automated tuck and lace combinations using both the LC and the KC to tuck.
Many are published in the Brother punchcard volume #5, but
they are not usable as provided in electronic machines.
The punch card machines repeat selection when the patterning carriage is retrieved for use from the opposite side.
The final charts in the DIY electronic versions will appear quite different, and although they may still be in repeat widths suitable for punch card machines, they are not interchangeable.
Electronic models advance the design for a row with each pass of carriages set for pattern knitting.
An idea using similar, alternating loop and lace diagonal shapes. In terms of fabric qualities, tuck stitch is short and wide, and lace tends more to long and wide.
Casting on and binding off may need to be adjusted to be looser in final projects.
Jumping right to the use of black and white pixels, following the arrows to track movements of both carriages to achieve the 24X36 final repeat.
Two all-knit rows occur after completing tuck segments, avoiding LC attempts at transfers containing tuck loops far beyond LC tolerance, capable of producing interesting LC carriage jams:  The swatch was tested on 50 stitches.  My seemingly endless supply of white yarn has reached its end, hence the color change and restart. As usual, the tuck texture is more evident on the purl side.  These were published in a Japanese knitting magazine from the late 80s, with accompanying symbol charts. Counting up from the bottom, it looks as though they were intended for use in Brother models, with row 1 marked 7 rows up on the right of the proposed punch cards.    Tentative planning in a spreadsheet for each repeat with arrows indicating the respective carriage movements.
The first preselection row is from left to right, and both begin with tuck patterning.
Testing the first 24X28 designquickly identified a problem area where already formed tuck loops with added yarn from the lace transfers try to meet more tuck loops. Cyan T cells represent tuck loops, the magenta cells the loops formed when emptied needles are brought back into work as the next row is knit. 1: The first pair of tuck loops is complete,
2: and meet the pair of lace transfers stitches to the left and to the right.
3: When needles emptied by the lace transfers are advanced to knit, the center needle between them is meant to tuck once more, but refused to do so with the next all-knit pass.
Often, the limit for the number of stitches or loops on any one needle to knit off properly on 4.5 mm machines is 4, unless the yarn is thin. A solution is to add an all-knit row to the design repeat, marked with blue cells. The amended design, drawn in repeat, checking alignments, programmed on 48X28 for test knitting, and mirrored horizontally on the 930enabled sorting out likely places to watch for any added issues, i.e., location and reasons for any dropped stitches. The second repeat, tested on 48X52, with the pair of added all knit row as above, still posed issues;   all-knit rows between the lace transfers must be programmed for execution by the knit carriage traveling from right to left and back to its home on the right.  Programmed 48X52Test knitting required mirroring on the 930

Pinterest inspirations vs implementation, tuck and lace combos 1

A companion to this post: Pinterest inspirations vs implementation, tuck and lace combos 2. Both are subject to edits and additions over time.

This has become an interesting rabbit hole for me. I am sharing working notes so far while I explore and document additional textures and combinations that move me forward, making them available to anyone wishing to participate in the journey.
Several images of tuck stitch combined with lace eyelets and diagrams with instructions in a foreign language not clear enough to attempt a translation led to this first exploration of what appeared to be the most complex pattern.
The source image: Pubs are not always in agreement as to the significance of specific symbols. In the published chart, the black dots are assumed to indicate stitches in hold or tuck, building up loops on the machine on the associated needles, the black triangles pointing to the left and to the right, the doubled-up stitches after transfers, and the curved shapes, the place where eyelets are formed after needles are emptied.
Many of my lace posts use cyan cells to symbolize transfers to the left, magenta for transfers to the right.
Starting with a symbols chart, in DIY, one may assign symbols that make sense personally. Conversations with self:
A row of knitting must happen in the location of the emptied needles after each lace transfer.
Each held stitch/ tuck gather in the source image is textured enough to indicate 2 loops represented in tuck stitch by pixel units of 1 in width, 2 in height.
Transfers should occur in the same rows as the first tuck loop formation.
The next carriage pass forms the second tuck loop, with single yarn loops on the needles emptied by the transfers.
Concurrently, the double tuck loops are moved forward on needles to the knitting position, along with preselection for the next first tuck row, and for the next transfers.
Transfers are made after every pair of rows before the next carriage pass, and the process repeats, manipulating needles and their stitches as needed, while also maintaining proper needle selection.
Watch for needles accidentally taken out of work after transfers.
Bring each pair in the transfer groups out to D or E; they need to knit on the next pass.
Getting started: this is a chart that also includes a plan for beginning and ending a program on equal repeat segments, with added cells marked in green.
Charts can contain as much or as little information as to be useful. The tuck stitches and the transfers in the final draft are both programmed as white pixels, resulting in the corresponding preselected needles remaining in the B position. The swatch was planned with 2 all-knit vertical columns on each side edge.
In many tuck designs, both single and double beds, having a pair to a few stitches on the edges, can provide a serviceable rolled edge that follows the pattern movement.
Since the programmed tuck side edges here are not symmetrical in my test PNG pattern, it was mirrored horizontally using the built-in function in the 930.
Leaving the carriage set to knit for beginning selections helps to identify the anticipated placement of the eyelets.
After the pattern was established, the work on the machine appeared to provide enough clues as to stitch transfer directions to develop a rhythm in making them.  This far “simpler” design was planned from the outset in BW pixels. Simplifying the automated repeat, starting in only black and white: all transfers are made toward the center needle in each of the groups of 5 unselected needles.
The 10X8 repeat,  programmed on 40X16 to include knit side edges, mirrored for use on the 930. The emptied needle and the one with the transferred stitch are brought out to E position, making certain the center stitch, the location of the tuck loop, remains in the B position.
The result is subtle, more evident on the purl side than the knit. The swatch was knit in 2/8 wool, first at tension 7, then at tension 10, an experiment in gauge and texture.
While on one side there is a 2-stitch border, the other has 3, and the eyelets on the 2-stitch side pull in a bit more and appear smaller than those on the opposite side, something to consider in planning finished pieces. Using the same concept, a yet untested design chart: the 10X20 repeat and 37X20 to match the chart Returning to a more complex design using a spreadsheet and a different approach:reviewing the guessed symbols in the pub at the top left, with the colored cell significance for this exploration in the center column;   in the table, 20 rows in height, every other row beginning with 1 at the top was hidden; symbols used previously and colored cells were added, including vertical columns in grey for planned needles out of work to heighten the effect of the tuck stitches.
and then with rows unhidden, colors were added in the needed locations.     The placement of black and white pixels began to be considered. This 20X20 effort replaces the white pixels in the third column from left with black, the purple with white for tuck stitches. Eyelet locations are marked in black as well. There remain 2 issues. When drawn in repeat in height, there is an error at the center,  which is eliminated by extending the height to 60 rows and shifting some pixels, now 20X60tiles without errors. The 20X60 repeat, without all the added black cells, can be printed and coded to suit, with added clues, perhaps even as a guide in an all-hand-manipulated version.
Transfer directions and their respective rows are annotated in this chart.
In the column with cyan and black cells, the cyan indicates tuck loops or needles brought out to hold, and the black indicates the return of those needles to knitting. The last consideration is that the columns with lace transfers need to be color inverted, or all those white cells will tuck. Unselected single white cells will then point to transfers, and the ground in their respective columns is black, with all those stitches knitting.
The swatch was planned for knitting on 50 needles with 2 stitch knit borders added at each side. On the machine: ladder locations > NOOW on either side of where tuck loops will form.Depending on the location in the repeat, transfers are made to the right or to the left on the center non-selected needle between ladders and areas with expected tuck loops, which are easy to identify as the knitting progresses.  after transfers are made, both needle involved are brought out to E position.

Punchcard volumes offer many variations for this technique.
Both the knit and the lace carriages select needles in pattern.
It is necessary to keep in mind when planning to attempt using the published card repeats on electronic models that they advance the design with every carriage pass, while the punch card models repeat the same needle selection when the alternate carriage makes its first pass from the opposite side. To match results, the electronic repeat would need to be edited.

Combining automated tuck patterning with hand transfers to form eyelets in vertical columns on a tuck stitch ground
For working on the single bed, the spreadsheet plan includes markings for transfers, magenta cells to the right, cyan to the left.
The repeat is 16 stitches wide, knit on a multiple of 16 needles +5.
The grey columns represent needles that are emptied and pushed back to the A position; ladders will be formed in those spaces.
The first and last stitches in each group of 5, marked with blue cells, remain undisturbed throughout.
Though the repeat could be shorter, it was tested in a 40 row height, 16X40on 56 sts, mirrored horizontally for use on the 930, air knitting the preselection row: as hand transfers are made, emptied needles and the remainder of each group of 5 must be in or returned to the work D, or E position to form eyelets amid kit stitches on the next pass. Watch that empty needles are not accidentally brought back into work. Vertical lace columns and rib:
End needle selection is cancelled, as in any case where not every needle is used on the knit bed
The knit carriage may be set to select, but no cam buttons are pushed in, knitting every stitch
Needle preselection guides the transfers, as with tuck lace, proper needles need to be taken out of work, and while hand transfers are being made, watch for needles being accidentally pushed out of work, or out of work needles being accidentally pushed back into work.
A vertical column is added on each side for a knit row, aside eyelets formed by transfers, the full repeat width remains a multiple of 5. Programmed repeat, 38X12The swatch needle setup with added needles in work for more knit stitches, first and last needles on the top bed: All transfers were made toward the center stitch, beginning consistently with the stitch on the left. The yarn used initially was a 2/20 silk/wool blend, which lost surface texture and flattened permanently with steaming and light pressing. The same proved true with a slightly different design using the same needle setup but with transfers on alternating sides. Using 100% wool yarn produced designs with a more defined texture. These knits narrow considerably when off the machine, and wool has spring back that may be diminished but not eliminated with blocking.
The programmed repeat used was the same 38X12 as in the first sample in the series.

Nearing the end of another year, reviewing previous drafts, I find myself coming across posts that were never quite completed or published.
This content began to be brought together in 2022.

The term brioche in knitting is used loosely at times in any references to tuck stitches. Designs may be worked in single colors, or with more complicated planning, they may be executed in 2 colors.
Some patterns are fully automated, with the knit carriage set to tuck in both directions, the ribber set to knit in both, others are worked as a tubular tuck, and lastly, some require frequent changes in cam settings in either or both beds.
My explorations for the use of tuck stitch settings in double bed every needle rib fabrics began with attempting to create a solid color shape on a vertically striped ground in Geometric shapes on ribber fabrics with tuck stitches 1.
The arrow marks the spot where both colors used were picked up from the changer. C1 and 2 show indicate cam setting changes used in the last part of the swatch.
 Here, a simple shape was programmed, and varied carriage settings on either or both beds were explored Geometric shapes on ribber fabrics with tuck stitches 2; knitting with 4 carriages. Geometric shapes on ribber fabrics with tuck stitches 3  explores self-drawn repeats in multiple colors. Added samples and files in the subsequent post New double bed swatches based on published sources of inspiration 2
Lace transfers meet fisherman rib in 2 colors on Brother KM 1Lace transfers meet fisherman rib, 2 color ribbed brioche on Brother machines 2 These are advanced, complex fabrics. The repeats for 2 colors can grow exponentially in length.
Returning to designing suitable repeats, beginning in a spreadsheet: grey vertical lines represent stitches on the ribber, which will force apart stitches created on the top bed, creating the more familiar tuck rib surface.
Mac Numbers offers the opportunity to hide both columns and rows. In this instance, with the 10 grey columns hidden, one begins to get the sense of shapes and movements needed on the top bed   Working toward a repeat for knitting the shapes in a single color, imagining the location of eyelets resulting from stitch transfers, I used two repeats, adjusting the first repeat to vary the resulting shape slightly A 11X30 repeat mirrored horizontally for use on my 930, tiled twice horizontally before programming and downloading, used as a 23X30 single motif to obtain a matching border on each side, A 9X28 repeat, my second try, programmed as a 20X28 single motif, When 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.
A slight shift in patterning may change the outline of the desired shape, introducing or removing stray lines or secondary shapes.
The possible cam setting options: In two-color brioche combined with hand-transferred stitches, the main bed is set to tuck in both directions, white cells tuck, black cells knit.
Brother machines preselect needles for the next row with each pass of the carriage, so on even-numbered design rows, as the carriage moves to the opposite side, all needles will form tuck loops on the main bed. The next row will be preselected, with some needles now back in B rather than D position.
With an appropriate transfer tool, move the stitches on the non-selected needles to the adjacent selected needle to their right after pushing it back to the B position. After each transfer, push all worked needles and their stitches, as well as the now-empty needle, to the E position.
As the carriage returns to the opposite side, an all-knit row will be completed. Several tension adjustments may be needed to ensure loops do not get hung up on gate pegs as stitches move across the bed, while still being loose enough to knit off properly.

Planning a fully automated design, reducing the ground, and staggering the color of the shapes. In these knits, the colors in the background form clear vertical lines:
24X44
brick repeat 24X88tiled.

A half-drop tiling error was revealed,  and the file was reduced to 23X44. The half drop repeat 46X44 Using the 24 stitch repeat executable on a punchcard machine as well, planning to knit the test swatch on 72 stitches, anticipating what will happen with color of the alternating pairs of rows forming the shapes, noting that the total number of rows is an odd multiple of 4:adjusting the repeat to 48X40with the total rows an even multiple of 4, tiling check, 72X80the stitches composing the all the shapes will knit in the same color The pattern, tested in thin yarns reveals the stitch structure even more. That said, the dark color was 2 thin yarns threaded on the same side of the mast. At one point, one of the 2 began to loop around needles, causing a carriage jam and a bent needle hook, hence the short height of the sample.

Passap to Brother 7: more Duomatic inspiration

My early posts were often quite brief, and some of the explored techniques were never returned to despite my intentions.
A shawl tale was written in 2009.
The designs explored in this post can be found in the Passap Duomatic baby book. A closer look: My attempt at a hand technique at that time, and the declaration of a planned challenge, “creating a downloadable stitch pattern that will automatically select appropriate needles and duplicate this texture.” It only took 16 years!
The pattern chart: on the Japanese machines, the beds are reversed. The back bed = ribber in our case, is set to knit every row.
Locks is the Passapese for carriages.
Many patterns can be achieved by lock settings and arrow keys without added programming. In Brother machines, a small cousin of the function is found in the use of lili buttons.
When an arrow key is pressed, it tells the Passap machine to engage the pushers.  Depending on the direction of the movement of the locks, the pushers will be lifted or pushed down. Their initial position is set up manually.
The left arrow key changes pusher selection when the locks move to the left.
The right arrow key changes pusher selection when the locks move to the right. Use of both arrow keys simultaneously will change the pusher selection every row.
With the Zero key, no arrow selected, the pushers do not change their position on that pass, repeating the selection.
Pushers preselect for the next pass, as happens with needle preselection in Brother.
AX is the tuck setting for Passap, pushers selected up knit, selected down tuck.
When setting up these patterns, it is best to have a needle on the ribber on each side, not observing the usual “needle rule” for rib knits.
When working on both beds, the default illustrations have a space > dot between needles in work to permit the illustration of needles between them on the opposite bed, so the chart is not for an every other needle design. In this instance,  stitches > needles in work occur in pairs on the top bed.
Programming the repeat: the first pass will knit or tuck alternate pairs of stitches.
The needle selection then stays fixed for 3 rows and reverts to the first selection, a 4-row design. Stitches will be tucked side by side, breaking another common rule.
The ribber needles in this case are extra, not transferred down to the ribber from the knit bed as in some of the fabrics recently explored in other posts.
They are brought into work between pairs of knit stitches on the top bed, represented by the red lines in this chart.

Because of their location, the ribber should be set for half pitch.
With use the beds can shift, for tips on ribber alignment please see post:
A bit on ribbers: Japanese KMs, alignment, and symbols 1.
The stitches on the ribber are outlined with cyan, the triple tuck loops as those needles are brought forward on the knit bed for knitting with white. The proof of concept, programmed on 46X24: The darker color was thicker, knit well, but since this was a test, seeing stitch formation while checking for accuracy mattered. Testing the pattern on the knit bed first determines any problems with the design before the ribber is brought into work, limiting visibility as the knit progressed.
The same repeat, with stitches transferred down to the ribber, leaving empty needles on the top bed, knit on every other needle with 2/8 wool, produced an interesting texture, but quite a narrow knit, 3.5 inches wide. Racking on EON rib: some considerations.
A different design, with the repeat cut in half widthwise for a more traditional tuck stitch configuration, 
also with stitches from the ribber between stitches on the main beda knot in the yarn knit right through and was missed, easy to do when working double bed if the yarn travels with no hesitationThis design uses a simple racking pattern, easy to execute in thin yarns, but not as impactful. In Brother the ribber performs the racking movements.
Both beds are set for plain knit.
The needle set up is on half pitch.
Cast-on for the test swatch was with the racking position starting on 8, with the plan to rack to 10, knit 2 rows, rack back to 8, knit 2 rows, and repeat, performing all position changes with the carriages on the left.
The yarn used is a 2/18 wool/silk blend that resisted the technique regardless of tension and weight adjustments, and began breaking, but there is enough knit to visualize the result. Pattern 2053 is for reversible checkerboards that use tuck settings on both beds,The strippers in the Passap system help push down on loops and knit stitches, anchoring them in a way simply not possible in Brother models. Even if a choice were to be made to push down between the beds with a hacked tool, the Brother needle preselection renders that impractical.
The concept behind the Duomatic version is then switched to automated patterning with the tuck setting on the main bed, and the ribber set to knit every row.
The two rows with one arrow key result in the repeat shifting locations by repeating the same selection, as seen in this chartThe 8X40 design was knit on 48 stitches, these knits are quite wide, loose bind off are required when the pieces are completed.
Each sample knit measures 11.5 inches in width.
Where 4 side by side needles are tucking for four rows, the stitches on the ribber may have a tendency to jump off, resulting in loops not being anchored, so those areas require special attention. The proof of concept for the above repeat in one color and then with color changes every 2 rows
