Figurative designs in mosaic knitting

Designs may be developed to incorporate lines and grids by outlining motifs, filling in the results with grids or lines, and even color inverting the results.
From an early 2013 post:
Each number on the grids below represents 2 consecutive rows of knitting. The design may be elongated in the drawing of the final repeat itself prior to punching holes, marking mylar or pixels, or elongated using the built-in setting in the KM used, whether electronic or punchcard.
Color changes are required every 2 rows.
The grids: After a motif has been separated, usually color 1 is represented in row 1, and all odd-numbered rows
color 2 is represented by row 2 and all even-numbered rows
long horizontal lines in mazes usually occur on odd-numbered rows
even-numbered rows typically have no more than 2 black squares marked side by side
on odd-numbered rows, the white cells slip
on even-numbered rows, the black cells slip
odd-numbered rows are knitted in the primary color (black cells)
even rows are knitted in the contrasting color (white squares)
Forming shapes and or text on the vertically symmetrical grid:

These single-bed knits are ideal when float control is an issue, or when one wishes to reduce the bulk of fair isle techniques. There are, however,  geometric design restrictions and the resulting patterns may be too “busy” for some.
Separated designs interrupted by black or white lines rather than single-cell dots are knit using slip stitch on the single bed, or in every needle rib with the knit carriage set to slip or even tuck in both directions on the top bed, and the ribber set to knit in both directions, a very different fabric.
The basic procedures for drawing figurative repeats may be worked out using graph paper or image processing programs, depending on what tools are available.
Working in Gimp, generate a file in a basic grid, which in turn may be tiled to any dimensions needed. Using the bottom grid is problematic in creating figurative mosaics using the connect-the-dots technique. Attempted vertical lines do not connect cleanly.   Cautious planning is required in executing figurative designs.
Clean-up will often result in solid color surrounding shapes or the addition of some short solid lines.
Doodling with blocks on both grids in a spreadsheet.  Text becomes more complicated if one seeks to emulate favorite fonts or to work on a small scale.
A spreadsheet using multiple colors may make the drawing easier to start with. By necessity, repeats will once more need to be large.
With practice, one develops favorite ways of reaching the chosen goal. Large shapes may be superimposed on either dotted grid for final editing depending on what sort of border one wishes to add in designs for end-use in large pieces such as blankets.   Figurative drawing occurs on rows marked with black pixels on the grid where black dots line up vertically.
White rows remain blank except where the black dots in the shape’s outline need to connect vertically.
After the outline for the motif is created, the filling-in of the shape is executed connecting dots once again.
By necessity, these shapes need to be large.
My first design is 68 stitches wide by 40 high. Processing the image is done on the same design. When color-separating Mosaics the design is not elongated.
Using the steps described in previous posts on a copy of the initial file: color invert, It is interesting to observe that the knitted result matches this image.
The file may begin as black and white indexed, but prior to adding colors the mode needs to be changed to RGB.
Add a third color beginning on every other row beginning on row 1,    using layer, transparency, and color to alpha, the third is removed, leaving black and white.  The alpha file is copied and pasted on the original resulting in a knittable mosaic repeat that requires elongation X2.
Check that the file is in indexed BW mode prior to saving it for knitting, it will need to be elongated X2 if used as is.  The above doubled in height, now 68 stitches wide by 140 high, may be knit as is.  Those solid black areas are OK. On the corresponding design rows, needle selections on nearly every needle will take place, those needles will knit the color in use at the time.
The tuck setting is possible, the final appearance will be quite different. For my swatch, I used the slip setting.
Slip-stitch pieces tend to have vertically straight side edges, while tuck ones tend to have wavy ones.
The floats on the purl side are still only 2 stitches wide.
The all-knit areas are not reduced in height, so they ripple initially and became flattened with blocking in this case, but caused the top and bottom of the horizontally striped segment to curve.
Starting knitting using the light color as opposed to dark will color invert the design.
The blue yarn used here is wool and the yellow is acrylic.
The swatch was steamed and pressed.
The dark color is dominant.  Visualizing the color inverted image using the photograph of the swatch rather than actually knitting it:  A 48X46 heart to play with for DIY Beginning in a spreadsheet followed by transitioning to Gimp can use a similar dot-to-dot design concept. It offers the opportunity to make adjustments before fixing on placement for the final black pixels over other colors. Moving away from dot to dot to “visually pleasant” does not necessarily work.
The flower design chosen and committed to for the moment is 37X32, visualized on possible backgrounds, and placed on a final one drawn with straight diagonal lines in pattern, for the test knitting  Aside from whether accurate tiling is possible for that final repeat, it has far too many white rows uninterrupted by black squares. As in any slip-stitch fabric, a stitch is held in every white cell or unpunched area location until a black cell or punched hole follows it, the result is very elongated single stitches on the knit side: There is a limit as to how big a part of any final mosaic repeat can truly be freeform.
It helps to develop a library of personal grid variations, to be willing to observe some basic rules, and to have an affinity for the overall look of the results.
In terms of the basic grids, the horizontal stripes have already been shown in the fish to produce 2-row all-knit stripes in alternating colors where they are placed in the design.
The vertical stripes create this result when proofed, and it can be recognized in the png for the body of the fish  Developing a DIY background: I find it easier to work on such designs on a large table in Numbers, which allows for placing a variety of colors and in the same document more easily, and then converting the outcome to a BW indexed png in Gimp. The smallest isolated repeat, in this case, is a square, 20X20 Make certain it tiles correctly before proceeding:
The final file doubled in length shows no areas where extended slip stitch rows might be an issue. This step is not necessary as one begins to trust the process. Returning to that flower, on the white-to-alpha ground, a 37X32 saved file, open it in Gimp.
Open a second file, using the background-repeat, and tile it X2 in both height and width to a matching 40X40 size.
Copy and paste the flower onto it in what appears to be a visually pleasing location, clean up the surrounds, and save the png.  Proceed with the now familiar steps: The final repeat must be elongated X2, color inverting may provide a better sense of what cells knit or slip, and it may be used to knit the design.     The working 40X80 repeat: Once again, the completed swatch visually matches the original file, color inverted.
The latter provides a sense for guessing if the knit results are pleasing and it offers a way to explore different colorways or matching yarn colors.
Pursuing the dot-by-dot concept can lead to endless DIY designs. Playing with motif scale in Numbers: Isolating part of the design in Gimp: 42X44  A variation using multiples on an 80X80 canvas.  Loving that DIY background? To create a frame
1. choose a finished canvas size, ie 120X120, and fill it by tiling the DIY background
2. open a second file to, in this case, 80X80, in any color including white. I chose yellow as a way to place black border lines more easily
3. copy and paste the second file onto the first
4. add a solid color border at the inner and outer edges of the frame, outlining the shape at its center.  At this point, any image also 80X80 may be simply opened in Gimp, copied, and pasted over the yellow. Files to play with: the frame with a transparent center to be pasted in place on other graphic files,  Here with a dot-to-dot center to draw on, and the file with central flower motifs to use or edit further.  The final choice then needs to be made as to how to use the final image.
One option is to separate the motif for use as a single bed 2 color slip stitch, and the second is to simply use the built-in KRC color separation in electronic machines to knit it as DBJ.
Motif definition requires large-scale designs limited by patience and imagination.
Autofill, command key and other shortcuts can help execute them more easily and quickly in spreadsheets as a first step.
This start of a hummingbird, inspired by a small segment of a Pinterest find, is already 54X101 pixels, ending my exploration of these knits for the moment.  

When editing or developing large images a series of guides may be useful. To configure them, see pos:t Gimp update for Mac 2

More shapes on ribber fabrics with tuck patterning, fantasy fair isle

Fantasy fair isle is the term often used to refer to dbj fabrics created using tuck settings on either or both beds. Typically in the required color separation used each design row in the repeat is expanded into 4 rows, with the same selection occurring for each color pair of consecutive rows. A tuck/plain combination is used here, with the backing essentially being a striper one, where each color knits every stitch on the ribber on every row.
In this illustration, the blue symbols represent knit stitches on either bed, the red, the tucked stitches on the top bed. The chart represents a single design row expanded into 4, the results would, in turn, be rendered double length in knitting the final fabric.  The last post related to this topic: 2021/09/07/geometric-shapes-on-ribber-fabrics-with-tuck-stitches-3/
Recently a friend shared images of a punchcard skull pattern she was using in a hat and followed with a query as to the possibility of using the pattern on a mesh grid. The inspiration for the conversation began with this image, the work of Claudia Scarpa. The possibility of adding images on a true mesh transfer lace or mesh-like thread lace images may be found in 2021/12/14/to-mesh-or-not-to-mesh-9-more-on-mock-filet-design/
My DIY skull image in a potential thread lace pattern, in a 100X92 pixel png.  Concurrently the topic of illusion knits on the machine has also resurfaced in FB with some spectacular panels executed using the Garter carriage and changing colors every 2 rows. Some small geometric shapes begin to have a somewhat “similar” appearance using this technique, but as with beauty, the success in the imitation is in the eye of the beholder.
The techniques involved: my proof of concept was knit using img2track on a 930. Traditionally two-color designs may be opened and then downloaded, using the standard dbj built-in KRC function for the color separation, not suitable for this dbj version, while for designs in 3 or more colors the program will separate the repeat in a way that each color for each design row is knit twice, the separation required here.
At this point, the color separation is executed by filling in pixels and observing a variety of rules. DAK produces templates of jacquard separations of varied types that may be printed for use outside its universe. The same file may be screengrabbed, traced, and redrawn pixel by pixel for use in a Brother download using other download software.
Passap by default separates knits for 2 color DBJ with each color for each design row knitting twice mode. Tucking on either or both beds is made easier because of the way stitches are formed on the Passap beds, along with the use of strippers which push down on tuck loops with each pass, ensuring that they will knit off properly. The fabric widens considerably when off the machine, requiring loose cast-ons and bind-offs. The dbj variant, dubbed fantasy fair isle, is often used to create lap or quilt blankets.
The Passap built-in reader techniques that are often recommended for large knit pieces ie blankets using the same design are 186 for throw size, 187 for lap blankets, and 183 for crib quilts. All three share the fact that the front bed pushers are selected in pattern in the up/knitting position alternating with the down/slip/tuck position alternating every 2 rows, producing the jacquard discussed here.
Slip settings produce narrow, short results, tuck short and wide ones. For non-Passap knitters, N is Passapese for plain knit, KX is tuck with patterning on the front/ knit bed, and AX for tuck patterning on the back/ribber bed.
Back in 2018, I began another post I meant to return to on traveling between the two brands.
My Passap E6000 manual is filled with scribbled notes from decades ago, expanding on how each technique may be used for a variety of fabrics.  In Fantasy Fairisle knitting using 187 with alternating up and down pushers on the back bed and AX with 2 arrow keys would match Brother ribber knitting with lili buttons used on an even number of needles set to tuck.
Working with the large skull image the setting of knit every row on the ribber and tuck in both directions on the knit bed is used as in technique 186, with a critical difference. Passap knitters may download the original black and white image while for Brother knitting a color separation is required.
The original skull image is 100 pixels wide by 92 high.
Converting the white ground layer behind the skull to alpha produces an image on a clear ground that can be placed exactly where desired on a new file with a white ground using the grid and guides
The alpha double long skull, now 100 by 184 pixels For the 1-pixel grid in Gimp to be visible on an editable image, a magnification of at least 800 is required. The options offered by default
can be changed to suit by simply typing in a new number.
As described in other posts including in Gimp update for Mac2, I chose to mark every other row with a red pixel, making it easier to track color-inverting every other row.  This is achieved by selecting the rows with red dots using the rectangle tool one row at a time and choosing Invert from the colors menu. The red dot will also change color, making it easy to locate converted rows in more complex patterns. The dotted blue line is a guide for placement. in progress   the processed image the trimmed 98X182 png doubled in length once more to 98X364 Knitting process on a 930 using img2track:
the 930 has a tiny brain, so the image is broken down by the software into multiple tracks of 96, 134, and 134 respectively. One of the critical differences when using this type of DBJ color separation is that the first preselection row is made from right to left toward the color changer rather than from left to right as in KRC separated 2 colors DBJ.
The first and last needles are in work on the ribber to ensure the edge stitch on that bed will knit every row.
The knit carriage is set to KCII, canceling the end needle selection.
Once the first row has been preselected and the planned color is chosen, with COL, set the main bed to tuck in both directions, leave the ribber set to knit, and continue knitting changing color every 2 rows.
In my swatch, the dark contrast color was used for the initial black pixel all-knit rows.
The work on the machine: A reminder: in my experience, the Brother cast-on combs are usually chrome-colored, Studio grey, and Passap, and I believe Superba ones were traditionally green. The first 2 were designed for 4.5 mm machines, the latter for 5mm. The different mm spacing does not make the 5 mm combs suitable for casting on on Brother, but they can be poked through the knit in progress. I like to leave the first comb and weights on, insert the new comb closer to the beds, and then move the weight up, and then remove the lower position comb.
There are lots of side-by-side stitches tucking on the main bed, made possible by the fact that each is anchored in place by a knit stitch on the opposite bed.
The tension needs to be set so that the stitches will knit off properly while having tuck loops not so loose as to get hung up on gate pegs. It can take a bit of trial and error to find proper settings and they, in turn, may need to be adjusted again when moving from small swatches to knitting on a far larger number of needles.
The finished piece measures 25 inches in width by 24 in height.
The appearance on the bed set to N, in this case, the ribber: Those white lines on the right are spots where the color changer picked up both color threads, a problem that does not occur in Passap knitting, where each color is picked up in its own yarn holder. In the Brother model, sometimes the yarn is left in the wrong place below eye level rather than its own individual one corresponding to its button, and both yarns are picked up with the next color change. The more textured knit side of the piece,  a close-up of the texture at an angle  Claudia Scarpa developed a skull variation using only layers in Gimp and has been kind enough to create a Youtube video illustrating the process. The separation is easy and quick as opposed to my more prolonged hack, and I will return to attempt to use it for various fabrics in a follow-up post.
This skull is more compact and better defined than mine. With the double-long original image superimposed on alternating pairs of black and white rows, the resulting png can not be lengthened again as tucking would then occur for 4 rows, not likely possible in a Brother machine. The variant is a very interesting cousin to mine.

In DAK using Method C color separation each color row separates into 2 rows of knitting and when using the result rows do not have to be repeated in pairs but the double-length switch will need to be used in Japanese knitting machines if working within the program. For those intending to use the separation outside the DAK universe, the color separation may be printed, traced/redrawn to create a png or bmp, scaled double length, and used as in the skull swatch. The template for the double long triangle in the post and the associated 24 stitches by 32 rows png, followed by the associated drawn png The png doubled in length, 24 stitches by 64 rows. This is a small repeat, suitable for punch card machines. The test swatch is knit with the main bed tucking both ways and the ribber knitting every row. It is possible to work some repeats on some machines with the ribber also set to tuck both ways with EON needle selection.
In Brother that is achieved by using lili buttons with an even number of needles in work on the ribber. The first and the last needle would be in work on the top bed, the KCI setting is used for end needle selection to ensure that the first and last needles on each side of the piece will knit. I did not find this method workable and soon had to stop because of a loopy mess. When using the Dak stitch design module, the color separation is automated. Choose any design repeat. This happens to be a 20X20 one, chosen from the thumbnail assortment, so not suitable for punchcard models. “Printing” the template using choosing the option of using dots rather than squares to represent knit stitches makes the resulting print screengrab easier to trace. the 20X20 repeat as a BW png The template was overlayed with a grid in numbers, filling in cells over the dotted areas.
A portion of the work in progress using the generated dbj option C template and tracing it transitioning from template to Numbers, to Gimp:  The result is screengrabbed, opened in Gimp, converted to BW mode, and scaled to the 20X40 expanded design size. Unless the double-length function in the machine is also used, it will need scaling again to double length prior to download.
Illustrations for the generated dbj option C template, tracing it in Numbers, processed in Gimp, The final image double length, showing the difference between the separation using the template, and that using layers as in Claudia’s video, which appears different but is actually the same repeat, color reversed.  Using bucket fill for the ground in the second layer, as described in the video, the captured clipboard image can be very small or stripes any width may be captured, even up to that of the full repeat widthRemember to click on the screen outside the area chosen with the rectangle tool before using the bucket fill in pattern tool.
The result is the same using either brush.
Alternately, the initial design may be scaled X4 to 20 X 80 pixels and it is superimposed on a ground flood-filled with 2 black rows alternating with 2 white rows the steps resulting in a match to the previous elongated version the 20X80 png In the related swatch patterning is used on  40 stitches by 100 rows. The relaxed fabric when off the machine measures 7 inches by 7 inches and the knit side view reflects the elongation of the design one might observe when using the same color separation in standard striper-backed DBJ. On the bottom, the swatch is stretched and the stitches are set with some casual steaming and pressing to 10.5 to 6.75 inches, gaining the familiar texture appearance seen in so many Passap blankets.
The color differences are due to lighting, with the photos being taken at different times of day.  
For a loose cast-on row, I used a racked version at the same tension as the body of the knit.
For a loose bind-off to accommodate the stretch, I used this method, one of many taught in Passap seminars.
To perform the same on Brother machines: knit the piece, ending with the carriages on the right.
Transfer all the stitches up to the top bed, bring the ribber needles up into work between them set the ribber to a looser tension number, here it was increased from 4 to 7. Knit one row from right to left, picking up loops on the empty ribber needles drop the ribber slightly by using this bracket lever position to elongate the main bed stitches.  Using a latch tool, beginning with the first stitch on the right, insert the open latch tool into the first stitch on the right, then insert it into the second stitch moving down until the first stitch is behind the hook. Do not allow the second stitch to go behind the latch, keep it in the hook. Pull the latch hook up moving the second stitch through the one behind it, forming the first chain. Repeat across the row, going through the center of each stitch, continuing the chained bind-off. A yarn end is pulled through the last stitch and the now completed chained row is secured The beds are returned to the up position, and loops and stitches are dropped off all the needles.

Visualizing knit cables 3_ using Numbers and Gimp

As our knitting experience grows, there are likely to be some techniques that engage us and others we choose to avoid completely if possible. Cables are in the latter category for me. I have hand-knit complicated pieces using them but dislike knitting them on the machine immensely. That said, I am periodically drawn to revisiting the topic in my blog, the resulting swatches are as proof of concept.
Small crossings may be used in sequence to create more complex appearing cables,  charts illustrating them may be simplified, using little or even no added color. The repeat is 8X8 and illustrates in the purl view. Ladders and knit columns between vertical sets of cables make the process easier to track, one needs to be alert to accidentally bringing the ladder back into work resulting in knit stitches, seen in the bottom left of the knit side swatch.      A table may be created to help with tracking multiple series of cables across a knit and their direction. It can contain as little or as much information as one wishes. Included here: the RC for possible crossings, their direction on the purl side for machine knitting (reversed for hand knitting). Columns may be added for including how many needles are left in or out of work between cable knit spaces or other info. It is also possible to print a custom needle tape to place underneath the involved groups of needles instead of marking the needle tape or the knit beds.  On a standard km, the needles are 4.5mm apart. A conversion reference for needle spacing point values Four needles X 12.75 =51 points, the width of the table cells, which in this instance are all equal in size. Colors and any other info may be added within each cell. Print in landscape orientation, making certain the image is not set to fit the page, but at 100%.
A narrower series of twists are made after every 2 rows knit,  the chart shows crossings on the purl side on the left, as opposed as to how they would appear on the knit side on the right Which leads to the topic of creating shapes by combining the repeats A brief effort containing at least 5 errors leads me to wonder about programming needle selection to help track crossings more easily and avoid mistakes. The center ladder here was latched up during knitting.  Adding the ribber: the simplest knits using the ribber are made with transfers to the ribber of single or multiple stitches to create what is sometimes called trailing stitches, with cables occurring at determined distances and appearing as knit stitches on a purl ground. Some samples of elongated ribber stitches with crossings on a striped ground may be found in the post on Slip stitch patterns with hand transferred stitches, double bed, the technique may be executed in a single color, or as shown here with color changes every 2 rows.  If only the knit stitches or purl stitches are crossed on one the same bed when knitting ribs, they will appear so on one side only. One example If the start is on the top bed, stitches on the ribber may be created by picking up bars from the top bed the yarn above was a 2/8 wool, which refused to cable on the ribber, and having the crossing was preferred to not changing to a thinner wool-silk solved the problem.  Using a punchcard or electronic program to track movements and cabling on the knit bed, each stitch in each pair of punched holes or pixels is crossed over or under the other. This is a very time-consuming fabric, not friendly to distractions or interruptions. Any crossing mistakes in the swatch were due to “operator error”. In reviewing the post after linking to it here I realized the now marked punchcard error at its top. The amended longer chart reworked in Numbers is also added to the older post. It is shown here aside from its tiled chart, checking for alignment, a habit developed as my skill and comfort in using spreadsheets grew, A png of the repeat, 24 stitches wide by 72 rows Tiled for alignment in Gimp as well.
It is possible to use the repeat working 1 X 2 stitch crossings for a very different look.
A large swatch is worth doing before committing to a large piece.
Correcting crossing errors (purple arrows) after the fact will be harder than doing so in some other instances or in a bulkier knit.
Keeping the fabric visible as opposed to between the beds begins to show a pattern on the reverse, which can also guide the direction of movements.
There are spots in this repeat where the center larger cables are not possible because of cables in opposite directions already occurring on either side of the group of selected needles (red arrows).
Transfers occur by bringing single needles forward and crossing pairs of stitches behind them, moving away from the center of the triangular half of the diamond as it is formed. The sequence is retained until after the wider cabled segments occur (black arrow and line), where there is no other needle selection aside from stitches to be crossed.
The number of plain knit stitches between crossings is always even.
The cabled knit areas have a depth that makes them project out and appear almost beaded in texture. Assigning colors to crossings in a chart may be helpful or too much info depending on one’s perspective, the bottom of the repeat is on the right.

Periodically, the topic of reversible cables turns up in discussions for both hand and machine knitting. They are possible when working in ribbing on the knitting machine.
Keep in mind that ribs narrow when off the machine, cables do as well, so a looser tension is generally required, and the basic fact that knit stitches are purl stitches on the other side and vice versa.
Cable crossings are made over purl stitches that separate them or the reverse. Changing rib needle arrangements will result in fabrics that may not always “match”, appearing different on one side from the other.
Using the half-pitch position before any transfer rows brings needles closer together, G carriages may be a boon but may have a hard time knitting the row immediately following the cable crossings and even jam.
On the machines, a 3X3 crossing is likely to be the limit. A general starting guide when trying out repeats is to knit the same number of rows between crossings as there are stitches in the cross, so 6 rows knit before a 3X3 cable.
A published illustration of bringing the ribber into play. Creating extra slack if possible on the row before stitches are moved is helpful here as well as when working on the single bed.
Stitches may be crossed on either or both beds. If trying that out, crossing on one bed, knitting a row, then crossing on the other is another thing to try. As with any ribber fabric, the view of results is limited, dropped stitches may be easily missed.
A straightforward idea to test: in a wide vertical rib make cables on both beds, testing whether it is necessary to reverse the direction of the crosses or not, the number of rows to knit plain, etc. The chart shows a staggered arrangement. The number of rows between crossings can be changed to suit. In my first test crossings occur on both beds and on the same row. Even using the thinner blue yarn at maximum tension the transfers were hard to execute. I had more success when I added 2 empty needles between the vertical ribs and brought one on each side of each rib into work on the top bed prior to knitting the last row between transfers, creating a bit of extra yarn to ease the crossings.
After the row is knit the same needles are pushed back to A position, dropping the yarn, and crossings are made before continuing to knit.
Results vary depending on the yarn, tension, machine model, and operator patience. The arrows mark the location of what appears to be a damaged needle, the tuck stitches were not deliberately planned.  Here the repeats are staggered, the edge with the ladder close to the end stitch is shown again to be far less stable than the one with more knit stitches. Spacing is varied, exploring the tolerance for the yarn to be crossed. The setup while working: If transfers are made after every 5 rows knit, crossings on multiples of 10 could be assigned to one bed, while row counts containing the number 5 could be made in the other. Sporadically pairs of transfers on the same bed may provide more surface interest.
The set up after transfers to top bed prior to binding off Trying out a simple repeat in smaller rib configurations will provide some idea as to whether the technique falls into the love of or not something to do simply because one can.
Charting can happen using the same method as in illustrating crossings in color, with some alterations, sometimes less information is more or enough.
The first repeats were knit with most stitches on the main bed, and a 2 stitch ladder on either side of the ribs involved in cabling to help visually with keeping the stitch location constant. The grey, purl cell blocks are as viewed from the back, the white cells represent stitches on the ribber.  A: the set up single bed, with needles out of work on each side of the planned cable space, tension is tested and 3X3 crossings every 6 rows are made first only on the single bed
B. the ribber needle configuration is set up
C. the cables are made after transferring ribber stitches up to the top bed, and then the same stitches are returned back down to the ribber before continuing to knit
D. the ribber stitches are transferred up to the top bed, and the swatch was bound off. Note the difference in width in areas where no crossings are made.
The step-by-step instructions apply to both instances: the chart shows 4 rows knit between crossings, instead, here 6 rows are knit in both tests.

The appearance of each side of the fabric differs
A: the knit was begun on the single bed

C: cable crossings were made as shown above
D: stitches were transferred to the top bed and bound off  An attempt at a larger swatch using 1X1 ribs:
the intended concept a custom needle tape rib set up for the yellow yarn the cable crossings using it were impossible, starting over with a thinner yarn at the same tension the ribber may be dropped after transfers up to the main bed, keeping stitches and crossings visible, making it possible to make corrections in any cables if they are needed before re-engaging the ribber and transferring stitches back down The concept is an interesting one and many arrangements based on the idea are possible. In the above swatches, when any transfers were made to the top bed, after crossings, a row was knit before returning stitches to the ribber. The extra row may or may not be noticeable, depending on the yarn and colors used.
More variants, analyzing columns in color using a crossing over single center stitch first and eliminating the extra knit row, and transferring stitches back down to the ribber immediately after making the cables. The rib will have a tendency to spring back when relaxed and off the machine, so the texture may be hard to see. Using a fiber that allows for some spreading out with some blocking helps to make the work more visible. A reference chart can be developed ahead of time for repeat variations. The number of rows between crossings can vary. When the crossing row is reached:
A: stitches are moved up from the ribber to the main bed
B: cable crossings are made
C: stitches that had been moved up are returned back to the ribber, keeping the original ribber needle configurationAssigning colors to columns reveals that stitches are not moved onto the same stitch type when moved over a single, undisturbed, fixed center stitch. Shifting the needle arrangements when cabling, moving across a center column of two stitches that remain fixed on the main bed, the cable direction as it would appear on the purl side on the left, the knit side on the right is straightforward here: I found the above impossible to knit, even with ladders for extra slack, and the swatch stopped when the yarn broke Returning to 1X1 rib, looking at the column alignment in color  There appears to be enough slack produced in the formation of stitches between beds to make the planned crossings possible.
A: the needles transferred to the top bed
B: crossings are made over the 2 center stitches
C: the stitches that had been moved up to the main bed are now returned to the ribber. Bringing cable stitches out and or up to the hold position helps ensure that they will knit properly on the next carriage passes.
The similarity between both sides of the fabric is increased
From a Brother pub, small crossings for a smocked effect The same approach may be used to create fabrics in tubular tuck patterns, easy to execute in one color. Once yarn, possible crossings, and their minimum frequency have been determined, the start of far more complex shapes can be explored using colors to represent the necessary direction of movements before any decisions are made has to how frequently to cross the cables and to get some idea of negative spaces created between traveling stitches. In hand knitting, a purl ground is easier to plan and maintain. Adding and removing rows in the tables or even changing colors is easy and quick in a spreadsheet, tiling in repeat with scaled screengrabs provides a quick reference for possible improvements/corrections before any actual knitting takes place

Visualizing knit cables in color 2_ using Numbers and Gimp

Though this post presents cable movements in colors using multiple stitches, the resulting repeats may be knit by hand or at times on the machines in single color textures and the number of stitches in any column may be reduced or expanded, keeping the direction of the cable crossings the same.
Though DIY charting may not be your goal, perhaps the charts themselves will inspire similar stitch movements. Segments of any of the charts may be clipped, saved, and manipulated for easy versions of other options.
My first published experiment with cables created in vertical columns of alternating colors was in 2012A quick way to imagine variations of the same pattern is to choose segments of the swatch photo and alter their direction and/or placement Using the spreadsheet, shifting crossings are imagined, adding a half-drop variation, creating secondary shapes. A variation doubling the width of the cable crossing in a half-drop repeat In machine knitting, one is looking at the purl side, and the ability to move stitches is often limited by the fact that their placement on a metal bed is fixed distances apart. Simpler repeats can be executed as isolated vertical bands on solid color or striped or even FI grounds, adding the ribber for even more complexity in execution.
Hand knitting makes moving crossing multiple stitches possible more easily, and because the crossings are usually made with the knit side facing, it remains easier to keep track of directions in which to move the stitches.
There are other choices in charting for either, cable crossings happen as a row progresses in hand-knit, in machine knitting, knitting stops and crossings are made before continuing with the next row. If color changes are planned every two rows then cables need to have multiples of 4 rows between each set of crossings. Hand-knit possibility on the left, with expanded charting for machine knitting I continue to be fond of visualizing results in color in a spreadsheet prior to knitting swatches. As usual, as the sample charts multiply, the techniques often evolve as well for creating them.
Without access to Excel, I am presently using Numbers 11.2 in macOS Monterey 12.0.1, a version with several changes from the previous. Working with shapes does not remain my preferred method, but shapes are useful and worth considering in drafts of charts for many stitch patterns outside this topic.
Notes on my process: to start with,  a table is created with enough cells to accommodate more than one repeat of the planned cable crossings in both height and width. I prefer working on a cell size of 20X20 pixels and using magnification if needed to make work details more visible, decreasing it prior to screengrabs for illustrations here.
The choices for cell border styles may be made both in terms of colors and line quality or eliminated altogether  To add a shape, in the toolbar, search for shapes and select a category on the left, then click on the shape or drag one onto the sheet to add it.
To browse all shapes move the pointer over the shapes pane and scroll down.
It is possible to create and save custom shapes.
To make a shape editable
1: click on a shape to select it
2: choose Format, Shapes and Lines, Make Editable from the format menu at the top of your screen, handles will appear. In this case, a red square in each corner, a small circle on the left side  3: double click a white handle to change the line from curved to straight, handles represent different types of lines
Squares with a red outline: lines that connect to this point are straight
Circles with a red outline: lines that connect to this point are curved
4: click outside the edge of the shape when done editing it
Saving custom shapes
1: Click a custom shape to select it, then choose Format, Shapes and Lines, Save to My Shapes (from the Format menu at the top of your screen). The shape is saved in the My Shapes category of the shapes library, which appears only when you have custom shapes. Shapes appear in the library in the order you create them, this order cannot be changed.
2. Type a name for the shape in the field that appears below it, or click the name to change it.
To delete a custom shape, Control-click it in the shapes library, then choose Delete Shape.
Color choices are the same as for any work with colored cells, for the default palette, left-click on marked area, choose from current fill selections Choosing custom colors: left click on fill, then on the colored globe, new selections appear, click on any one of the pencils to select the new color, it will move up from other selections, the change will be reflected, can be undone and repeated several times Creating the first cable crossing shape: choose the square from the basic shapes, if the first plan is to work across 3 cells, change its size to the width of 60 pixels, 20X3, and single height of 20 pixels, also changing colors if desired. To do so, left-click on it, uncheck constrain proportions, and change values to desired ones Change its color It is a good idea to copy and paste a few shapes outside the table in case they are needed
A: place the shape on the cell grid
B: make shape editable
C: click on the left upper corner of the shape on the small white square, it will turn red, drag, and place it where desired, release it
D: repeat with the small white square in the lower right corner, release
E: check image size, adjust to 60 pixels wide, 20 high, make editable again if tweaking is needed,
F: the first crossing shape is completed Right-click on the final shape, copy it,  and paste it several times on the sheet away from the table.
Copying and pasting shapes on a single cell will fit any image within its borders, to remove it choose the cell, color fill, no fill, from the format menu To use the shape, left-click on it, drag it into the desired position.
Cable crossings are usually in pairs, so a companion shape will be needed, 60 pixels wide by 20 high, in a contrasting color, the results of making the larger image editable

The combined images may be created in a paint program such as Gimp and the resulting file, in turn, may be used in a spreadsheet. Pngs can be custom filled with any color of your choice in Gimp or its equivalent To draw a straight line in Gimp when applicable, select your preferred brush tool, click the point that begins your line, hold the Shift and Command keys in a Mac, drag the cursor to where you want the line to end. Click the endpoint, this creates a straight line between the two points with your selected brush. After the line is drawn, release the Shift and Command keys.
When charts are for personal use only, individual preference guides visualization methods, considerations for publishing may be different.
Yarn colors may be used in the charts, moving wider columns of stitches may be difficult if not impossible on a machine, but hand knitting opens a different world of opportunities for pattern use.
Working in a spreadsheet is easier for me than only using Gimp.
Seeking out a method for better definition of cable stitches to facilitate following crossings visually, cable crossing rows here are now double-height for added clarity; other choices include showing grid or not, and using BW for stitches crossed to the front in any direction.
Disregarding the grid, each column of color could be any number of stitches wide, while having the grid allows for easy counting of rows. Any chart may be used in knitting using a single color as well. Fair isle repeats: when working cables in FI, in addition to tracking cable directions, the needles must be placed in the proper needle positions B and D for correct patterning to continue.

The red border surrounds the full repeat.  These illustrations are as they would appear for hand knitting, with crossings made as knitting progresses along the corresponding chart rows on the knit side of the fabric Fair isle on mixed striped ground  Fair isle with repeat changes, expanded further by mirroring An expanded MK illustration A FI sample shared in 2015From Slip stitch patterns with hand transferred stitches, single bed   2/21
When using fair isle patterning as a guide to forming cables on the machine, crossing directions matter more since one is no longer simply placing color on like color: this chart transitions from the original idea to the placement of the crossings, a full repeat with their direction reversed based on which color is wanted to travel to the knit side is drawn, and on the far right, the look of the final FI repeat  Adding a third color, possible intarsia knit as all over pattern or isolated as a panel. Even in hand-knit, the latter may be in a contrasting gauge and joined to pieces of the garment after their completion. These repeats may be worked as vertical panels between rows of plain knit or rib Symmetry is not always needed, MK, adding the ribber: one of the things that may lead to confusion is the use of the term every other needle knitting. If one is working on every needle on both beds, the needles on either bed are centered between those on the opposite one, thus patterning occurring on either bed that becomes EON. Colors are used to track the movement of stitches, not colorwork, which happen on the same needles, either bed, the plaiting feeder may be used to produce the illusion of additional colors. Part of an experimental swatch using the ribber and tuck settings In attempting brioche on the machine the color changes happen every 2 rows, so a minimum of 4 rows or a multiple of 4 rows are planned between moving any stitches. Although the same color will be used in the crossings each time, using 2 colors for cable segments may make the chart easier to follow Using the ribber, one of the crossings on striped grounds: Slip stitch patterns with hand transferred stitches, double bed.  2/21A range of experiments with associated samples:

DAK DBJ color separations, templates, other software

Over the years I have written on an assortment of methods for color separation in knits including DBJ, a summary post with links to previous shares: 2017/10/26/dbj-and-color-separations-some-previous-posts-links/
and in the-start-of-a-blog-index/

A variety of textures and patterns may be used to achieve fabrics that are very different in appearance, using a very simple pattern along with cam button or lock setting changes. The first chart was generated at that time using Intwined Pattern Studio, a program that for a time appeared to be very promising and then moved on to lack of updates for Mac making it useless in 2013, followed by none for Windows as well, with no successful use of it reported in forums in years, but apparently one may still purchase it The manual color separation method for punchcard machines.
The elongated X2 repeat version of the triangle drawn in Gimp As for more than 2 colors per row, performing the color separations may be achieved manually, various software is now available for performing the work in instants. Ayab offers an elegant color separation solution, heart-of-Pluto, that will knit single passes for each color per row on the front of the knit, resulting in 3 color patterns with limited design stretch, and no worries about the placement of one color over any stitches preceding it in the same color on the previous pass. The difference in the same design being knit with the standard, elongated version, allowing for two passes with the same color prior to each color change and the Pluto version.   knit using img2track, the vertical stretch is manually set to X2, A “hack” 2021/01/24/img2track_multiple-colors-per-row-dbj-each-color-knitting-only-once/

There is a Russian punchcard site that will allow entering personal repeats or selecting one from their extensive library, where it is possible to obtain related 2 color dbj separations as well. The punchcard color separation may be created manually, a slow process, while the punchcard templates in Dak are achieved with a few, quick clicks of a mouse. The repeat may be created as a graphic file, in my case a png created with Gimp, the elongation in Arah because Gimp fails to scale small repeats cleanly. The image may then be opened as a graphic file, stitch and row counts should match, and save the stp 

if experimenting with changing selections and this window appears it is OK to click on No The separation methods in DAK:
Method C separates each color row into separate rows of knitting, rows do not have to be repeated in pairs, the double-length switch will need to be used in Japanese knitting machines The elongated triangles repeat template is different from what would be produced with the above set at double length, may be used as is to produce a variety of fabrics including quiltingYarn choice and design make a big difference. Here the yarn is really far too thin, and the repeat too narrow in width, but the possible result is illustrated. The main bed is set to slip in both directions throughout. The ribber setting needs to be set to slip in both directions for every other pair of rows. When the ribber slips, the main bed will knit the color that will create the pockets, where there are many single stitches selected here, the KC was set to KC1. When the color is changed and the ribber is set to knit again, stitches in that color will knit on both beds, sealing the fabric in those areas and forming a solid color background on the reverse side. Here the white forms the pockets, the floats after a pair of passes are seen in this photo. Because the yarn is so thin there is a considerable grin through on both sides, the areas marked with arrows indicate where the white pockets were lightly stuffed with yarn ends     For a review of quilting on machines including Passap see 2018/02/15/revisiting-machine-knit-quilting/, and using a second knit carriage with a modified sinker plate for knitting stitches on main bed only, making ribber settings fixed throughout, and allowing for tension adjustments for each color yarn.

Method A works on pairs of rows. If the pattern does not consist of identical pairs of rows there are likely to be yarn error messages. The original triangle elongated to 8X16 If pngs are created outside the program, they may be doubled in length unless the repeat is designed that way. The associated menu options in Dak when the plan is to work in double jacquard How the different jacquard setups process the specific repeats:
Method B creates the same separation as the default built-in KRC one in Japanese electronics. If knitting DBJ it may be used with dak if the pattern is downloaded as fair isle but the machine will then needs to be set for dbj. If additional colors are used, pairs of rows will follow a single pass for color1. The print preview templates, if generated within the stitch count restriction for use on punchcards, may be used as guides for punching the required holes, this would be the card for that 8X8 triangle repeat, a tad shy of the recommended 36 rows, Passap card reader techniques saved from long ago experiments.  Method C see top of post
Method D 
separates each color into a separate reader card and is used to download to the PEI or Passap, appears to use superimposing of layers, and to match method 4 in my post.
Method E is suitable for machines with a color changer on each side, like the Brother CK 35
Method F is a Half Milano separation. Each pattern row is separated into a pair of passes for each color, but the second row for each color has no patterning, so the rubber stitches only knit as the carriage returns to the left side, a possible way of creating repeats for drop stitch lace on Brother machines. The elongated triangle template was split into 2 pages for viewing, they are combined in this image This may be the associate Passap Reader technique, I have no way to test it Processing the template using numbers: a table is created twice the length of the 8X16 triangle repeat, followed by hiding the 32 odd-numbered rows, positioned in front of the scaled punchcard template, stitch markings are traced the rows are then unhidden, the repeat is checked, matched here to the F jacquard separation in DakThe numbers table is processed in Gimp to obtain the png for knitting the now 24X64 pattern  Proof of concept swatches: the long stitch in 2 colors,  and the pattern executed as a tubular FI knit: I had yarn issues, hence the dropped stitches. Both swatches were knit to approximately the same point in the pattern repeats, there are obvious quality differences in width and length. In tubular knits, there are differences in the width and height of the knit on each side. The front is actually a slip stitch with floats, drawing the fabric in, while the ribber knits every stitch every other row. With a good choice of yarn and pattern, loosening the tension on the top bed may ease this problem. As often happens, casting on and binding off need special considerations ie to allow for any fabric stretch when off the machine or in order to leave a tubular knit open at either or both ends if that is the goal.

The method for color separation used for mosaics

The sources of inspiration from hand knitting or industrial knitting machine designs are endless. There are many features that simply cannot be duplicated, sometimes compromises can be reached that can achieve only imitations of the original. To my mind when knitting garments or long pieces the greater the degree of automation, the less likely one is to have patterning errors occur, in ribber fabrics, they are also more complicated to correct than single bed knitting.
I recently came across a pin of a Ravelry hand knit pattern which led to my return to this topic once more, including perhaps the addition of more colors. The plan is to create a repeat which may be knit using color changes every 2 rows. Each design row knits each color twice, so the standard built-in KRC separation is not a consideration, though the same cam settings may be used in those fabrics as well.
The required color separation has been discussed in several posts on the various forms of DBJ, a review:
The initial test repeat is 18 stitches by 44 rows, designed using 2 X 2 blocks, to begin with. How it might appear knit in fair isle:  Transitions in charting visualizations:
A: FI repeat with pattern progression in two-row increments
B: every even-numbered row beginning with row 2 is color reversed
C: B repeat is doubled in length to 18X88 for initial samples
D: repeat adjustment for a first try at introducing 2 additional colors End needle selection is canceled, the first and last needles are in work on each side on the ribber knitting every row, the first preselection row is from right to left, cam buttons are set after the left side is reached. Knitting in these samples began with the blue yarn in the number 2 position in the color changer. The ribber remains set for knitting in both directions throughout, the images on the right do not reflect the amount of surface 3D textures.
with the main bed set to tuck in both directionsLock settings are easier to achieve on the Passap than switching out cam buttons in Brother machines. This was knit using 4 carriages. Color one knits with the main bed set to tuck both ways, color two knits with the main bed set to slip both ways. The slip stitch reduces the width of the fabric considerably Here each color alternately tucks and slips. The choice of cam buttons matters, tucking first from left to right, slipping from right to left, with cam buttons set COL after the first preselection row This last cam setting appears to my eye to produce a texture “close enough” to the inspiration fabric. Attempting to add more colors: the repeat, D, is still 18 X 88 but is now shifted slightly.  Somehow the slip cam button was not set, so the knit carriage tucked in one direction while knitting in the other. I am vaguely reminded of illusion knits. Considering altering both the color choices and placements again. A way to imagine exact color change placements beginning with solid colors repeats once more, which can be followed by new color separations. The existing repeat may be reduced further to 18 X 64, eliminating some of those extra rows in the center of the chevron shape  The new BW image, tiled: Whether or not the design is intended to retain chevron shapes in alternating textures, actions may be plotted pre knitting in any way that visually makes sense to the person designing the pattern and tools available to them. Reversing the png so that the more textured stitches will begin with the color in yarn position 1Using either repeat, color changes now occur after every 32 rows knit. Another color change location clue is in the needle selection change above and immediately following the red border in the chart on the left.  Adding colors can be planned cautiously or allowed to happen randomly depending on the preferences of the designer and end-use. Ribber fabric designs are not visible until several inches have been knit, too late to catch color sequence errors. Some machines allow for memo placements or sounds to help track color changes, but only within the initially programmed repeats. A quick spreadsheet can provide customizable checkboxes or added information. For an attempt to retain chevron shapes in different textures: When using 3 colors, rather than 4, the texture of the zigzags on any specific color, will vary in placement. It is easy to change colors in any chart to approximate those that will actually be used in the knitting.  Proof of concept: each of my yarns is slightly different in both thickness or fiber content from the others, which can be a drawback in resulting textures. As in any 2 color dbj, if 4 consequent rows are knit in one of two colors the positive and negative portions of the image reverse, as seen at the top of the swatch. The green was not intended to be used originally, the white yarn simply ran out. Such accidents at times may provide pleasant improvements. There is bleed-through of each color behind the other in the tighter knit areas as well which contributes to visual color blending, noticeable even in the areas with fewer tucked stitches.

An editable Excel spreadsheet created as an export from numbers zig zag
For Mac owners a Numbers doc. zig zag
A simpler repeat suitable punchcard owners as well using only 2 colors The test swatch and observations: patterning was begun with color 2, yellow.
The yellow yarn is 12/16, the maroon is 2/15 in thickness.
The triangle, because slip and tuck stitch settings are used, is compressed in height, while there is enough tuck happening to still make the knit wider.
The pattern is 24 stitches wide, the swatch was knit on 40 needles. Smaller swatches are fine for testing tension and colors. If committing to larger pieces, tests on at least 100 stitches by 100 rows are needed for gauge calculations in any double bed work or very textured patterns on the single bed.  On some occasions when a far larger number of needles are in use, problems may turn up that require going back to the drawing board in terms of items ie tension settings, weight used, etc.
A: patterning was begun with thicker yarn, the yellow, in color changer position 2, both yarns are 100% wool
B: KCI, end needle selection on, a 2 color “beaded” edge is created
C: KCII, end needle selection canceled, patterning occurs on end needles
D: transferring to the top bed and using the standard latch tool bind off for these fabrics is far too tight  The tiled repeat, 24X48, does keep the stitch quality constant for both colors, Assumptions based on optics of tiling are not always accurate clues to potential patterning errors, here those darker lines are part of the actual design Continuing on a 24 stitch repeat, the original design may be rendered at double height and separated once more, doubling the separation height to 96 rows There are days when either or both machine and knitter need a break. At the start of the first swatch, the cam buttons were not set, resulting in plain knit stripes. At its top, the purple did not get picked up properly from the color changer, and the knitting of course fell off the machine. On a second try, the same issue happened again with the purple yarn. Multiple incidences of such events were fondly nicknamed “dropitis” by my students. The test is on 24 stitches, the width of a single repeat, the triangles are much more balanced in size, this knitter is putting this pattern to rest.  Another try at the diamond shapes that began this topic. The first .png when tiled appeared to not have enough space between the shapes, was amended to this the differences when tiled the color separation can happen completely within Gimp using color invert the white yarn is an acrylic, slightly thicker than the purple toned one. Sometimes simply exchanging yarn positions can change the qualities of the overall fabric. The repeat begins with 2 blank rows. To achieve the tighter white shape as opposed to the honeycomb purple one, at the start of the repeat that color needs to be in use on rows where knit stitches happen as the KC, set on slip to the right, knits needles brought forward to D position. Red in this chart segment marks pertinent rowsBoth with hand knits and commercial knits because of the hand actions possible on both sides in the first, and as many as 4 beds selecting and knitting on the other may be in use at the same time with more complex needles as well, there are fabrics that are difficult or even impossible to duplicate. There often are obvious differences in the results, but the journey may still yield results that are pleasing and worth pursuing. Another even more complex inspiration from a sweater attributed to Falke, Spring 20 collection, using similar stitch structures, but in addition, also transferring stitches between beds exposing a purl striped ground.

Numbers and GIMP: online punchcard patterns to electronics 2

In the progress of being reviewed and edited, with added information 12/2022
The most recent Gimp Update

There is a Russian online site offering a huge range of punch card designs. The question of how to convert the site files for use in electronic machines surfaces periodically and did so again recently in FB groups.
My posts with information related to this topic:

A Russian language tutorial on converting punchcard images using DAK
A recent video offering on navigating the site in English, begin viewing on minute 5
The site link
Small previews link for FI
The translated site link  offers larger previews
The options in English for working with published cards The help menu is available after the card is chosen Designs are presented on pages that list them from longest to shortest row counts for the complete repeats. Punchcard users can reproduce holes as given. There is also an option for entering a new design and it appears, in turn, one may be able to generate a separation for its use in DBJ.
Beginning with a smaller design intended for machines with 12-stitch repeat restrictions simplifies the view and processing of it for newbies. The published patterns are offered Silver Reed ready. The option for converting the cards for use on Brother 260 renumbers it with the appropriate location for the number 1 row marks required by the operation of the different brand’s card reader. Toyota versions are also available. Making the holes larger is a boon to reproducing the drawing correctly regardless of end-use. Splitting the card into segments is helpful when using factory blanks with a 60-row maximum repeat, and often also when processing the image for use on electronic machines, which is affected by screen size views available to the software user. For some reason, I found the commands erratic when working on the translated version of the site, and fared much better in the original language publication.
In the 2022 adaptation, the small previews were chosen for conversion to pngs rather than the full card templates used below.
The chosen card image may be dragged onto one’s desktop. I use Numbers to create my tables. The 2 all-punched rows, marked with blue arrows, and any standard vertical rows of holes on each side of the provided designs need to be isolated and eliminated. This is a 12-stitch repeat required for use on some machine models or useful when using a thicker yarn on every other needle to achieve the same design, every other vertical row is blank.
A: the table with cells 20X20 sized to match the number of rows and stitches in the original. The card image is arranged in the back of the table with the constrain properties option unchecked in its image-arrange menu.
B: cells corresponding to marked holes are filled in with black since the final goal is to create an indexed BMP or PNG.
Using and holding down the command key during cell selection helps perform the coloring cells in action on groups, clicking on any cell again while still holding the key down will deselect the fill. Release the key, choose the fill-in color, repeat, and continue until the holes in the full design are filled in.
C: click and hold the command key, select every other blank vertical column marked with letters at the top of the table, the blank vertical rows are selected, release the command key, right-click on any of the same letter selections again, and choose to delete selected columns from the pull-down menu or after marking the rows directly from the table menu at the top of the screen. Eliminate all cell borders. The result shows how the pattern will appear when used to program fair isle.  Screengrab the final image surrounded by extra white cells, and open it in GIMP.
Change the mode to indexed BW, crop the file to content thus excluding any extra white cells, and scale to the original design’s 24 by 74 dimensions. Punched holes are now pixels; export the knit-ready BMP or PNG.
Using the filter, map, and tile options allows one to check on horizontal and vertical repeat alignments for any errors and begin to imagine how the repeat might appear on a finished piece. Color exchange may be used on the BW files converted to RGB mode to visualize the knit using specific colors. On the far left below the final BMP is shown magnified X 800 with a superimposed grid, then filter-map-tiled to 48X148 size. It is followed by a BW color-reversed version of the same, as well as color-exchanged ones. Getting a preview of how a finished garment might appear, here the tiled version is 192 pixels in width and one may glean some idea as to whether that repeat should ever really be used in a sweater or even a blanket. Further image scaling or cropping can happen based on the knit gauge. A very quick rendering imagining pattern and color placements using a simple sweater outline Collections of every other needle repeats for processing with a similar approach may be found in these volumes, available for free download

In machine knitting, the word lace is used in categorizing a large variety of knit fabrics. The terms include:
simple lace, executed with carriages that transfer and knit in a single pass
multiple transfer/ fashion/ fancy/ lace: executed with carriages that transfer only
lace and fine lace combinations
fine lace
tuck stitch combined with transfer lace
tuck/ pull up lace
transfer lace combined with weaving
punch/thread lace
ladder lace
punch tuck rib
drive/drop stitch lace
If one explores the second selection for 24 stitch cards looking for openwork patterns for 24 stitch cards, the resulting  20 pages of repeats do not differentiate between the lace categories, so the onus is on the visitor to determine proper repeat use.
In addition, the option for switching machine brands does not readjust for changes required for the pattern to read correctly in the alternate machine brand card reader. As an example, transfer lace cards are shown with blank starting rows, ending with punched holes, a Studio brand feature, and in some cases with a punched row ending with blank rows, a Brother feature.
If changes are made in machine brand selection, the only adjustments in the new image appear to be made to the numbering sequence, but not to the punched or unpunched starting and ending rows.

For punchcard users or enlarged views: printing the PDF breaks the repeat into segments required if one is using individual 60-row maximum length factory cards and not a punchcard roll. On the far right, the difference in relative size between a factory punchcard and the PDF image printed without any adjustments.  Filling in the dots with a black marker renders the to-be-punched holes more visible through the card, making marking prior to punching easier and faster.  For a better, printed match size, after capturing the image from the PDF for a single page outside image edges, opening it in Gimp, and cropping it to content, it is then possible to scale the results to measurements of a factory punchcard equal in width and adjusted for the number of rows in the image. My card required print measurements were 14.1cm by 26.1. Scaling executed with an aspect ratio that is too long.  breaking the chain-link, removing size constraints The result with printing to match the card stock measurements was extremely close to the desired size, useful, but hard to photograph  Entering patterns: the translation Working with the Russian menu:

2022: This process appears complicated, but with some familiarity with both Numbers and Gimp, can be fairly quick. Revisiting the site, I made the accidental discovery that working with images as shown below, by superimposing a Numbers grid to these point measurements, developing the designs became quicker and easier to manage  Two instances: from any black and white chart and a seasonal 24X120 repeat from this website.  Beginning with a published and gridded punchcard model: I am used to converting patterns for testing and using them on electronic machines. If the goal is only to have a printable template for marking holes to be punched, see the very bottom of this post for the quickest method.
The technique steps reviewed as applied to pattern # 403 as seen in this scan  Open the image in Gimp, and crop to the outer edges of the selected punchcard. Eliminate unnecessary information by using the select tool and bucket filling each area including non-repeat information with white. Adding a visible pixel line along one of the edges of this image will help locate handles for adjusting its size on the white spreadsheet ground. Save the result.  In Numbers, at 100% magnification, create a new table, 24 cells in width by 48 rows in height. Using a thicker cell border in a contrasting color is useful, here the border style is set to 3 points. Drag the image onto the spreadsheet, place the mouse pointer on and hold it in place on any one of its handles, appearing as white squares along its edges to a larger size than the table, then use Image Arrange and uncheck constrain proportions. Select the whole table, and drag and position it in front of the image.  Using the image handles adjust its size and place it for easy tracing.
Size and position in the Arrange menu will help with fine-tuning. Fill in the cells above the white squares visible beneath with any color that will facilitate keeping track of the marks.  Move the table away from the image at the end of the process. Visually check for any obvious errors in the overall repeat.
Scaling while retaining the odd number value resulted in patterning errors.
The problem was solved by resizing the table cells to even numbers, 14X14 points.  Remove all cell borders, and set the zoom at 50%. Screengrab the result with a white border around it.
Open the grab in Gimp.
Use the Image and Crop to content option.  Set Fuzzy select to select by color click on the contrast color, and pixels will be surrounded by broken lines select bucket fill to black, click on rectangle select, and then anywhere in the window to fix the result, the dotted lines will disappear  Follow with these steps
Image Mode menu, convert from RGB to BW Indexed Colors Menu, and choose Invert. Image Scale to 24X48 Magnify X800, Show Grid, and check for any errors.
Save the file.
Filter, Map Tile for the repeat alignment check.  The resulting, proofed repeat, 24X48 The top row of images summarizes the steps using Numbers, and the bottom row the results using Gimp  See punchcard templates for more information on associated settings, including downloadable spreadsheets.

Using the setting for centimeter ruler units, a partial segment of the above table’s repeat was printed. The result is shown ready for tracing over an improvised light box The squares on the card with black cells beneath them may be marked with any tool. For the result to be knit in the tuck stitch setting, users would need to punch all unmarked squares. If only the marked squares are punched, the pattern card could instead be used for thread lace in machine models with that capability.
A slightly different approach for pattern 8095 from the Russian site. Prior to committing to the process, check the row numbers in the PDF, and make certain the repeat is correct. This one happens to have a missing, blank row Using the small preview from  http://perfo.12rus.ru/index.php, download it Open it in Gimp
Crop the image to eliminate the border
Fuzzy select by color the background which only appears white.  Bucket-fill the ground with white from the Gimp palette, and only the repeat will remain Do not convert it to indexed
Create a Numbers table containing 24 cells in width, and 58 in height using the centimeters ruler setting, with cell size set at 0.5cm wide by 4.5cm high. The full table size will measure 10.8cm by 29cm.
Drag and drop the design image onto the sheet, resize it to table measurements, position it underneath the table, and begin filling in cells.
A: in some instances, it is possible to work all in black. As I progressed up the repeat I had to readjust the image placement slightly
B: the image size was tweaked to measurements of 11.2X29.1, and a separate color cell border is used
C: the full repeat is separated into sections to fit on standard letter sheets when printed. The result: The electronic repeat: Before committing to a knit, using Gimp, Filter, Map, Tile, check alignments. In addition, the result helps visualize whether or not the result is what was expected If the only thing needed is a traceable template for punching holes using the 11.2X29.1 measurements in resizing the cropped preview in Numbers, open it in its own sheet, watching its placement and you are good to go! Working in Gimp alone, the alternatives to working in pixels: Using a screengrab of a DAK DBJ color separation: the repeat itself is cropped to its edges with the rectangle select tool. The size is calculated using the formula for the width and height of cells in the unit measurement of your choice, ie cm or mm. Even though scaling is done with the chain link broken, the program will round off the values to very slightly different numbers. The printed repeat underneath a blank punchcard is ready for marking.  When using Numbers, the program will separate the repeat into segments for you if needed. My charts and results have been produced using default document borders.
If using only a paint program ie in the above case Gimp, the user is in charge of dividing the template into segments that will fit on the printed pages. Using legal-size paper can in many cases avoid printing on multiple sheets.
Some math is inevitable, the considerations involved:
in terms of mm and cm, 1 mm= .1 cm, ie. 216 mm+ 21.6 cm, a shift to the left with the addition of a decimal point
Working in cm: using punchcard 8095 once more
Each square on a blank punchcard is 4.5 cm wide and 0.5cm high
Full punchcard: 24 stitches, the fixed width for punchcards = 10.8cm
58 rows, the variable, in this instance = 29cm.
In printing, using default borders:
US Letter: 45 X 0.5 = 22.5 cm = maximum # design rows
Full repeat = 58 rows X.5= 29cm.
First sheet: 45 rows X.5=22.5cm
Second sheet: 13rows X.5= 6.5 cm 22.5+6.5=29cm
On Legal61 X 0.5 = 30.5cm = maximum # design rows

It is possible to download a PDF of each card from the website. When downloaded and printed as given, my result can be seen as obviously off-scale

 

Visualizing maze or mosaic potential from tuck or slip stitch repeats

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

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

Brother shadow lace, rib transfer carriage

I have probably owned this accessory since the early 90s. After making a faint-hearted attempt at using it at the time and failing, it has been stored in the original box in the interim and just came out of retirement. The multiple languages operating manual for its use may be downloaded from http://machineknittingetc.com/brother-ka7100-ka8300-transfer-carriage-user-guide.html. There are several video tutorials available on Youtube. As a group, they generally illustrate simple transfers across an entire row in structures such as ribs used for bands and cuffs. This one is offered by Knitology 1×1, Elena Berenghean, a young knitter publishing very good machine knitting video instruction on a huge range of techniques.
The tool is designed for the standard gauge and transfers only from the ribber up to the main bed. It is best to use yarn that has some stretch. The recommendation in the manual and in youtube videos is to perform the transfers with the pitch set to H. My own ribber is balanced, I found I had problems with transfers in that position, several carriage jams, and to get things to work properly in half-pitch I had to use the racking handle to move the ribber needles slightly more to the left for the transfers. The needles containing stitches to be moved, need to be slightly to the right of the needles with which they will share yarn, that spot may turn out to also be just wide enough to allow for the pattern to be worked without changing the ribber pitch.  The yarn used is a 2/18 Merino, knit at tensions 3/5. In terms of positioning the carriage, a wire that is akin to that found on Passap strippers is on its underneath. In positioning the carriage on the beds, check visually that it is indeed lying between the gate pegs of both beds prior to attempting to travel with it to the opposite side If any carriage jam occurs, it takes cautious wriggling to release the wire and carriage. Upon completion of the transfers, simply lift up to remove it from the beds.
Generally, the ribber tension used needs to be set on 4 at the minimum. The last row just prior to transfers will likely need to be knit at a looser tension than the remaining rib. If the stitches are too small they will not be picked up for the transfer. Folks familiar with lace knitting are aware that just the right amount of weight can make a difference in forming proper transfers. With these fabrics, too little weight may result in loops forming on gate pegs, too much weight, and stitches may remain over closed latches on the ribber needles and not share their yarn for transfers.  Again, the transfer carriage operates only from right to left.
Studio instructions for their version of the accessory actually offer some different and more specific recommendations. When knitting full needle rib all the needles or pattern segments the machine generally will be in Half Pitch. Though there are needles in work on both beds, the ribber should be set to full pitch, aka P position, “point to point” prior to transfers, bringing them in close alignment in order to facilitate the process. Passap machines accomplish the same by changing the angle of the racking handle to other than the full, up placement in order to achieve the necessary alignment.
The Brother accessory and its parts, have clear imprinted illustrations for use

The change lever has only 2 positions, up and down respectively Its position is determined by the number of needles on the ribber one wishes to transfer.
The carriage manual recommends its use after knitting a last ribbed row to the left, but it is possible to use it with both knitting carriages on either side, as long as there is generous space to clear all stitches when the accessory is placed on the bed, moved to the opposite side, and removed. An extension rail may be needed to achieve that amount of clearance.
Operating slowly, one can watch the process of transfers while moving from right to left. Though skeptical, I found the transfers happened easily, with occasional skips. I worked with hand-selection of needles on the ribber to create a pattern, first with hand-selection, then with racking the ribber position to change the relationship of needles on one bed to the other, initially transferred after every 2 rows knit. The knit carriage was set to knit both ways, the ribber to knit in one direction, creating loops on the selected needles, and securing them in the other, allowing for the loops on the ribber needles to be transferred up to the main bed, before working 2 more rows. The “errors” in patterning were operator errors in needle selection as stitches were dropped, and not all the required needles were then returned to work position. Not a technique I would use for all-over fabric, but good practice. When the transfer occurs properly, the ribber needles will have yarn placed over closed latches, ready to be dropped, the yarn is shared and looped over stitches on the main bed, akin to tuck loops, outlined in the photo with the black oval. The first image is from the manual for the accessory, while in the photo, one improperly transferred stitch is outlined in red. To prevent dropped stitches from happening, any such locations will require a hand transfer to the opposite bed before dropping the remaining ribber bed shared stitches For my test I used EON needles on the ribber, planned alternating selection for each new transfer. This could be done by selecting dashes and blank spots on needle tape ie. dash in the above photo, blank spaces below  It was faster to achieve the effect by changing the ribber relationship to the main bed using racking by one position ie 10, 9, 10, 9, etc. prior to picking up the subsequent set of loops. The errors in the test swatch were from failing to bring all the needles back up to work after dropping their stitches. Using a tool ie. a ribber comb placed over the out-of-work needles prior to dropping stitches made the racking process far less error-prone,  will keep the appropriate needles from being accidentally taken out of work. My first attempt at creating shapes includes a band at the bottom where the EON transfers as above were made, but every row. Simply bringing needles into work on the opposite bed creates an eyelet. They can be eliminated by sharing stitch “bumps” on the opposite bed, but for the moment they are a design feature. The texture created appears in the areas involved on both sides of the knit It is possible to transfer single needles at sides of shapes ie or whole rows, but the change lever needs to be set to position accordingly.

Many knitters have one of these tools in their stash,  they are sometimes referred to as “jaws”,  intended to facilitate transferring between both beds, and patterning was intended for Studio punchcard machines. The enclosed punchcards: Shadow lace tools are marked side 1 and side 2. Some are blue on one side, cream or white on the other, the blue side is side 1. The process always begins with side 1, or blue. When the stitches have been removed, the jaws are closed, allowing the stitches to slide over to side 2. The jaws are once again opened, and the stitches are transferred to the opposite bed. Studio machines select and knit in single pass rows. Brother preselects for the next row of knitting while knitting any one row in pattern as well, so transferring in pattern from the top bed down with such a tool would be problematic to maintain proper pattern needle selection.
To transfer from the ribber up on any machine, place the teeth of the jaws on the needles on the ribber, holding it with both hands. Pull needles up until all stitches are behind the latches, then push down with another tool or one of your hands until all stitches are on the jaws.
Release the tool from the ribber needles, and rotate it away from you, toward the main bed. Close its teeth so the stitches are transferred onto side 2.
Open teeth, place eyelets over the main bed needles, and stitches are transferred onto the main bed by rotating the tool away from you just a little and tugging down a bit.
On Brother, the possibility of having patterning on the top bed to help track patterning on the ribber in some way comes to mind. This was my start, with the first draft of electronic repeats. I stopped when I began to have some tension issues, loops on gate pegs, and a distracted brain.
Transfers of stitch groups, whether by hand or using the accessories are made on rows where no needle preselection occurs on the main bed This series is a proof of concept for my approach to developing electronic cuesThe original repeats were modified to include 2 blank rows between segments that allow for transfers between beds not hampered by needle preselection on the top bed. The motifs are color reversed, but not the blank rows between themThe knit carriage is set to select needles KC I or II, end needle selection does not matter. All needles on the top bed knit every stitch, every row, whether or not those design rows contain black pixels. No cam buttons are pushed in. Blank areas between black ones indicate the number of needles that actually need to pick up loops on the ribber to create shapes, filling in spaces between selected needles until an all-blank row is reached for making transfers. The chart on the far right illustrates a shape where the easiest method becomes one where stitches on the ribber are manually transferred to the top bed in order to reverse the shape and maintain every row preselection. The selected needle corresponding to the black square marked with the top of the red arrows is pushed back, the ribber stitch below is transferred onto it, the needle with the couples stitches is brought to E position, moving across the bed in proper locations prior to knitting the next row.  In this repeat, the side vertical panels of ribbed stitches are added. The knit stitches on each side of them roll nicely to the purl side, creating what in some fabrics can actually be planned as an edging. My takeaway is to test the accessory with some patience, sort out the sweet spot for the ribber needles in relation to main bed ones in terms of handling transfers and yarn thickness, use colors that allow for easy recognition of proper stitch formation, keep good notes, and “go for it”.

One way to add color to the mix is to use the plating feeder.

In the first sample, equal thickness yarns were used, the colored yarn was a rayon slub with no stretch and slippery nature. The bottom of this test used a wool yarn of equal weight to the light color, which proved hard to knit. The red is a 2/48 cash-wooll A very narrow test for a possible pleated pattern  

It is possible to construct the same type of fabric on a striped background. It can be achieved low tech with graph paper and pencils if needed, using a simple paint program, Gimp alone, this is my process using Numbers and Gimp:
1. determine the desired shape, width, and height, checking that it also tiles properly
2. create a table with square cells the same width as the number of stitches in your design, twice its height; use an even cell size ie 20X20 pt
3. hide all odd-numbered rows from the top of the table down, the table will shrink from 20 rows to 10
4. draw your repeat
5. unhide all rows
6. copy and paste the table; double the cell pt height only to 40, making the repeat twice as long
7. mark corners or part of the edges with another color to make it easier for Gimp to identify them, select all and remove borders, grab the image with an added surrounding colorless border
8. open the screengrab in Gimp, use crop to content, fill colored squares with white, change the mode to indexed BW, scale the result to the appropriate size, in this case, 18X40, export png Cast on for EN or EON rib. Transfer all the main bed stitches down to the ribber. Extra stitches can be cast on and transferred in addition to the planned width of the repeats to create a border on either side of the designs. During patterning there will be stitches in work on both beds at intervals, so the pitch needs to be set to H while knitting. When the top of the piece is reached, transfer all ribber stitches to the main bed and bind off.
The first preselection row is knit from right to left in the contrast ground color.
With COR bring all the needles to be worked in the pattern color to B position on the top bed.
The knit carriage is set to slip in both directions. End needle selection is canceled. The ribber remains set to N/N for the duration. Knit to the left and begin changing colors every 2 rows.
The shape increases are created automatically, with eyelets at the edges where each stitch is picked up for the first time on the top bed. COL when the first needle is preselected in this case for the start of the next shape, transfer all previously formed design stitches on the main bed down to the ribber, continue knitting If any stitches are pushed all the way back or in mixed alignment during transfers,  be sure to return them all to B position, not disturbing the needles already preselected for the next pattern row,  repeat as needed. Because one color knits with every carriage pass while the other slips behind it not knitting for those 2 rows, the striped background fabric will become distorted depending on yarn and stitch size used, most likely particularly noticeable at the top and bottom edges of the piece.

Mosaics and mazes charting meet Numbers, GIMP 3

If working in Numbers, the solution to doubling the height of the final repeat for mazes or mosaics may be achieved by simply doubling the height of each cell prior to screen grabbing the table and processing the resulting image in Gimp. Here the cells for a single repeat in the table on the left are copied, pasted, and altered from 20X20 pixels to 20X40Working in 1800 magnification, using rectangle select, every other pair of rows is chosen and then color inverted. B: the process continues for the height of the repeat. Until each new pair of rows is selected fully, the last color inverted pair is bordered in a dotted outline C, useful in tracking the last worked location. As the subsequent pair of rows is selected fully, the dotted border will disappear. The processed repeat  Its tiled visual check  Proof of concept: the bottom half is knit using the slip stitch setting, the top half in the tuck setting. The added texture on the tuck stitch purl side makes the fabric a more interesting, reversible one, and wider than its companion.  For a different way of working with two-color initial images using only Gimp, see tips in Gimp update for Mac2.The process used on the beginning repeat, redrawn in 2 colors and then, in turn, elongated X2 or drawn double long to start with, tiled to check alignment. There are 2 options for altering colors in 2-row segments to achieve the separation, the first is color invert, the second is value invert, found in the colors menu. Both require color filling in of cells so as to obtain the final BW image, the value invert option, in this case, would require only filling in the green to white, but in managing larger images I believe having the additional colors make the process easier to track accurately. The color invert option will substitute a third color and white on every other pair of rows. Flood fill the original color 2 on rows containing black pixels with white, then fill color 3 pixels with black on rows containing white pixels: The mazes that are often seen in game-playing, puzzles, historical sources ie in Chinese design references, may not work out for knitting with this method, the result can be quite muddied.  I recently found a new to me online maze generator http://www.ludiculus.com/maker/mazes.html.  Changing the pixel width by default also doubles the image in height, making smaller designs for knitting problematic  This was a quickly drawn maze using it, shown with its cropped repeat on the right, then tiled. Numbers processing to ready the repeat for final gimp editing: The repeat when tiled predicts muddied results which are noticeable in the knit swatch. Because of the side-by-side areas with multiple white cells, the slip setting is used, not tuck. The single slipped lengthened stitches do not produce an easily recognized secondary design on the knit side Getting back to clearer pattern results: when using electronics, it is possible to create far wider and taller repeats for download. The technique to achieve them uses the same process. A new working repeat: its tiled appearance  My starting table in numbers with hidden rows, beginning to isolate a smaller repeat the isolated repeat, double-length the color separation in progress
When knit, that white cell pair of rows break up the overall shapes and shifts the pattern in the top and bottom half When I tiled my next draft, I decided I preferred a cleaner join at the center The final adjusted repeat knit using the tuck stitch setting in both directions, KCI, first row left to right, leading with the dark color and here with the lighter color In progress, on the km  the relaxed, 3D-ish view on the reverse why projects can take longer than planned The finished, relaxed scarf with pressed edges only, retaining the conical striped formsThe repeat knit double length, changing colors every 2 rows, becomes something quite different, with a sharp curl to the purl side
