Seasonal knits inspired by published repeats 2_hearts

Charts are included for repeats suitable for punchcards, where the designs must repeat in height to a minimum of 36 rows.
Some reminders: the BW pngs here are intended for import into a paint program or image processor where they can be magnified to suit, with a grid view for counting cells to consider the width of floats if used in single bed fair isle, adjust the design in DIY variations, or import into download programs as provided.
The tiled repeats help to visualize how the final appearance on the knit side.
While the pngs are shared in BW indexed mode, when dragged to desktops or otherwise copied and are opened in image processors, they may change to RGB mode by default and will need to be converted back to BW indexed mode prior to use for import and download to knitting machines.
Some machine models will automatically mirror the image horizontally, depending on brand and model year as does Ayab software.
When direction matters, ie in representational designs or transfer lace, the mirroring may be performed on the image provided before using it, or by using the appropriate button or command after downloading to electronic machines.
Punchcard users can mirror after the fact by simply turning the card over before inserting it, after marking and numbering at least the starting row on its reverse.
To retain symmetry in developing half-drop or brick repeats, it is useful to have an even number of stitches and rows in the original design. Some designs are broken up in ways that are subject to use based on personal visual preferences.
If used for blankets, the repeats can be tiled to dimensions leaving room for coordinated borders.

Among the mylars saved even though the machine was sold many years ago, I found this repeat, 24X47 cells, the last offered in this series. Studio mylar sheets were marked in 6X5 blocks as opposed to Brother’s 5X5. The punchcard repeat chart here is outlined in 6X6 blocks of cells, the convention in Brother punchcards. the png

Small to large repeat figurative designs inspired by filet crochet charts

Reducing figurative designs to repeats for knitting on a low needle counts results in loss of definition.
Filet crochet charts can serve as a starting point for repeats, but usually are planned on  more than equivalent 24 stitch counts, so results of adapting them are often usable on electronic machine models only.
The knitting technique used to execute the design determines whether the lengthwise aspect ratio is affected or not.

5: the color reversed image to visualize the possible appearance of doing so in the knit
6: a small border frame is added, bringing the figure color to the edges of the knit piece, and the figure is mirrored, helping to make a choice about its orientation on the the knit side  Depending on the model machine used, the motif may appear as drawn on the purl or on the knit side, mirroring it when direction matters may be done using machine settings or mirroring before download.
On my 930 mirroring was not necessary, the swatch was knit on 40 stitches, with the added frame.

43X53 squirrel  This image is not from a filet crochet chart but from one of my Studio 560 mylar sheets dating back decades. It is used to illustrate the possibility of mirroring in different directions to produce far larger designs ie wall hanging or blankets.
Alone it could serve as a scarf, with the image rotated and perhaps even mirrored at the opposite end of the scarf to match directions when draped around the neck The 60X50 cell repeat It takes a few clicks of a mouse and a couple of program windows nowadays to make the addition of single cells at the top, bottom, or sides of such large designs that avoid tiling intersections with double cells if that is the goal.
It is also easy to manipulate the chosen designs to visualize the appearance of a final piece. Printing the pixelated results in a larger format can aid informed choices before any actual knitting.
Adding a single cell blank column on the right, and one with a few pixels on the bottom a blank row on the top, 61X52 in a 122X104 repeat that with coordinated borders could approach the use of most of the needle bed with the initial shape mirrored horizontally and then drawn in repeat a column with double pixels appears again at the center of the design staying with that, but making shapes go around

Seasonal knits inspired by published repeats 1

In previous posts, ie Numbers and GIMP: online punchcard patterns to electronics 2, I shared some ways of converting online images from varied published sources.
This series was edited using primarily ArahPaint and some Gimp, both are available for free.
DAK users have the ability to achieve similar results in that universe, producing stp proprietary files. There is no export (or import) available to other formats ie png or bmp possible.
Fair isle is not in my preferred wheelhouse, especially in season specific designs, but that said, I have been sharing these repeats in the FB machine knitting forum  and thought I might make them available to others here as well.
The pngs are editable for further DIY modifications.

the original, 24X185 with the elimination of some rows, first at the very top and then just above the snowman’s hat the final 24X182 png The question as to how to adjust repeats for use on 12 stitch knitting machines often comes up in forums.
Continuing in the seasonal vein, the easiest method is to begin with a 12-stitch repeat that occupies only half of the card vertically and twice in width. Here the original “half” is 12 stitches wide, 46 rows tall.
One method for the conversion is to work on a spreadsheet:
Begin with a table 24 cells wide, adding enough rows to the expected planned height to repeat the snowflake border, 46 cells in total
configure the cell borders for easy viewing, ie with a 3 pt red lines
hide 12 columns beginning with the second from the left
fill in black cells matching the original design or the DIY version
unhide all 12 columns for the final repeat  When converting the screen grab from a spreadsheet to png in Gimp, before scaling to final size, a first scaling may be required to make certain the result is divisible by the expected number of stitches and rows using the broken chain link, and then scaled again with closed chain link, the first png Working in Gimp or any paint program
draw the “original” and save it, mine now has 2 added rows, one above and one below the deer, making it 12X48 pixels scale it to twice the original width configure the grid properties for contrast/easy viewing
fill in every other column with white using a straight line white pencil. To do so, select a pixel with the mouse, hold the shift and command keys down to draw the lines, and release the mouse to stop. The first white pixel may be placed within an easy-to-follow section of black ones and then the mouse may be held and moved up and down to complete each column. Save the result.
Proof that it is always a good idea to draw the initial image in repeat before committing to color separations or any downloads and actual knitting:  Two possible alternatives in adjusting the design to one’s preference are marked in 6X6 grids in ArahPaint to match markings on blank Brother factory blank cards:
the first removes a snowflake border and is reduced to 12X39 pixels, the second adds 4 rows at the top of the second snowflake border, 12X52 the number of rows between motif segments can be varied for planning the introduction of stripes in added colors If only Gimp is available, I have not found a way to vary colors in grid borders in blocks other than to use guides, appearing as dotted blue lines.  A break from reindeer, teddy bears, and hearts follows, perhaps for a baby gift or to save for Valentine’s Day. When there are clear horizontal borders added to motifs the half-drop repeats will produce mixed results.  the pngs:

This might appear in casual observation to be a “snowflake”.
The full 25X25 pixel version can be isolated, with matching fragments around the whole. Magenta lines indicate cropping points depending on end use if double stitches not immediately obvious or planned are to be eliminated. A: the full design as a potential knit border
B: trimmed a one-pixel width column on the right to 24X25 while retaining matching top and bottom rows C: trimmed the single top row  as well to 24X24 for an all-over execution, drawn in repeat for an opportunity to evaluate whether the design as it now appears produces the initial imagined shapes and effect  Then there is the optical effect change that happens with color invert, for which an easy test may be made during knitting by simply switching yarn color positions in the knit carriage sinker plate

Swatches based on adapting random online published repeats

I still surf Pinterest daily and often encounter published punchcard repeats that catch my eye.
Many need some interpretation and editing for use in specific machine models.
The first inspiration: is knit using 4 colors, alternating 2 rows of a base color, then rotating color changes for 4 rows for each of 3 contrasting ones.
Counting up from the bottom of the illustration after the marks for the typical two all-punched rows, it would appear this is a Studio punchcard, but starting row 1 as visible outside the card reader can simply be changed for any other brand knitting machine.
The every other stitch configuration is for an every other needle repeat used in early machines such as the Juki.
A full reference volume   An illustration of the card use  If using thicker yarns on a standard machine that grinds at the loosest tension, this configuration can retain the full design while knitting every other needle/EON.
The adaptation began using Mac Numbers, the repeat was isolated and traced, and the 12 blank columns were then hidden producing a result scaled in indexed B/W mode to 12X36 pixels. The tiled design, checking alignments.  The proof of concept Periodically tuck stitch designs that appear to break the usual rules for the stitch are discussed.
This design is intended for a push-button machine capable of 24 stitch repeats, uses symbols in the associated chart interpreted to mean tuck loops form for 2 rows and knit along with all other stitches every third row.  The working repeat is made up of 8 pixels in width, and 36 pixels in height.    This next design is likely published for use with the Studio color changer, which is marked with letters for each color,   rather than with numbers as in Brother models.
It is intended as a slip-stitch. The bottom swatch relies on color changes every 3 rows, which would need to be performed manually.
In the elongated version, colors are changed using the color changer, every 6 rows.  The design was first tested in thin yarns using the electronic 24X84 elongated PNG  tested for alignment   and displays interesting 3D variations, the purl side is remindful of shadow pleating  Changing colors every odd number of rows is a tad fiddly.
The use of the color changer is not an option.
With the three yarns fed through the yarn masts, it became hard to keep them from twisting around each other. Ultimately, that problem was solved by hand-feeding one of the three colors with the cone on the floor, in front of the machine, as one would place yarns for weaving.
Brother knitters are familiar with yarn placements in the sinker plate.
Position A is for knitting when using only one color or for the ground color in fair isle patterning.  There is a “gate”, which is closed, and the B color/contrast motif color is placed in that front position, knitting the yarn in needles preselected to needle position D on the next carriage pass.
It is tempting to leave the gate open when switching colors by hand frequently, and that may work for a while, providing tension is placed on the yarn manually to keep the yarn back. If at any point the yarn shifts forward (green arrow), with no needles in position D, stitches will be dropped.
Textured stitches can make for more complicated correction of errors or dropped stitches.
Taking the extra seconds to close the gate (red markings) after each color change avoids what became fondly known as “dropitis” in my classes.   The proof of concept: two of the yarns used were acrylic, so steaming to reduce the curling of the swatch flattened the texture.  At one point Studio published a newsletter  with cover art composed of simple drawings, such as this, for #143, which spiked my curiosity, and led to these explorations:
the pattern and symbols refer to tuck stitch, but technically the design is executed using short rows and transfer techniques.
The programmed repeat selects needles, making tracking actions easier.
End needle selection is canceled.
No cam buttons are in use.
The knit carriage is set to hold.
Stitches on the single needles selected on rows, 2, 12, 22, etc, are transferred onto the needle on their left. The empty needle is then pushed back to A position, out of work, creating a ladder.
The groups of 3 preselected needles are pushed out to hold, the D position, before continuing.
After every 2 rows knit, a stitch on the left is pushed back into work, until lastly, the empty needle is returned to the B position.
All needles will then knit for one row filling in the empty needle with a loop and a full knit stitch on the next pass where transfers begin again. A brief summary of stitch manipulations  Images of the work in progress, a small claw weight single claw hung on edge stitch helps keep side edges equal in length:
preselected needles initially manually brought to hold position after the first carriage pass to the right
after the second carriage pass to the left, with the first needle on the left in each group pushed back into work  the second needle on the left in each group is returned to work
one needle in each group remaining in hold pushed back into work  at this point the empty needles have been brought to the B position, single preselected needles have been transferred to the left,  and a pass is made forming loops on the empty needles/ eyelets  The original 18X30 repeat, some machine models and download software may require that it be mirrored horizontally,   repeated to 44X30 with a planned distribution of plain stitches at sides, knit in 2/18 wool blends: Converting random transfer lace designs poses different challenges, and since the time at which the reference post was published, there have been several Gimp updates.
Lace designs contain few black and white pixels and, at times are brand-specific. Multiple transfer lace in Studio models begins with 2 blank rows, while Brother begins with a design row, and ends with 2 blank rows. As given, the inspiration repeat is designed for Studio/Silver Reed.
When using any program, ie Gimp, ArahPaint, or even Dak, the original scanned or screengrabbed design needs to be aligned horizontally and vertically to window borders for accurate conversions.
Gimp:
Before any scaling of images, establish stitch and row counts. In this case, they are published as being 16 stitches X 96 rows.
The process for converting the same lace design using Gimp 2.10.34 on the Mac, beginning work in RGB mode:
1. drawing a straight line to the side of the cropped image reveals a slight lean to the right
2. using Image, Transform, and Arbitrary Rotation -0.30 improves the alignment  3. using the rectangle tool, crop to the borders of the published image.
In this instance, the cropped image measuring 199X938 pixels is at first scaled to multiples of 10 for both width and height, note the broken chain link
4. 160X960 pixels. 5. Image mode is changed to B/W indexed, and the image is scaled once more to 16X96, the size of the expected repeat, note the intact chain link  6. the final repeat, when studied, matches that from the results in the previous post  1: the result using ArahPaints tools, including its guess weave from grid, compared to
2: the Gimp final image and
3. borrowed from the previous post illustrating other considerations before actual knitting,  
which include:
if using the repeat on Brother machines, the first 2 blank rows of the design are shifted to the top.
The 16-stitch design width makes it suitable only for electronic models.
The final PNG is actually downloaded as a fair isle pattern while maintaining the required needle selection for lace, and the knit carriage remains set to knit throughout while the lace carriage selects and transfers.
The machine, depending on the model, may by default mirror the result vertically, so the final PNG can be mirrored and saved as here, prior to knitting on the 930, or the mirror function in the machine may be used after programming.
I prefer to save my files in the orientation required for the actual knitting as a means to avoid confusion or errors.
Working in Arahpaint, rotating an image turns it on its center point. To rotate a layer, selection, or image, from the Image menu, choose Rotate.  Selections can be made at offered angles, or specified degrees can be entered in the degree field, or select an area, move the pointer outside the bounding border, and then drag on any one of the small boxes at each corner while pressing the left mouse button.  To align the image,
1. load the lace inspiration
2. choose Image, select Rotate Image, and draw a line that follows the orientation of the image. The color will be based automatically on the palette being used, and altering the pencil pixel size or color has no effect.
The program then rotates the image and will inform you of the rotation angle, and the drawn line becomes straight.
To confirm alignment, click the OK or Close button in the Rotate Image window.
3. use the rectangle tool to select the content for the full design repeat, and crop the aligned image to the selection. 4.-9. continue with the steps using the tool Guess Weave from Grid, producing the same final PNG. In summary, they are:
4. crop the selected image to size
5. change the color palette to 8-bit, adjust background and foreground colors
6. reduce the number of colors to B/W, adjust the threshold, and set the number of colors to 2
7. the resulting image
8
. use the guess weave from the grid tool, crop the bounded image to the selection, magnify the results to visually check the repeat, and save the PNG if satisfied
9. the final 16X96 pattern design repeat, matching the Gimp result. The associated swatch  This Pinterest find is credited to Tatiana Demina, and is intended for use on Studio punchcard machine models.  Studio machines are capable of transferring and knitting in single carriage passes. Studying the image of the card, it can be seen that there are no blank rows anywhere, and punched holes on alternate rows indicate transfers alternating first to the left, and then to the right.
The swatch was knit using the same technique described  recently in the post Unconventional uses for punchcards 2: thread lace cards for “filet” mesh
The original 24X56 design was lengthened X2 to, shown here also doubled in width to 48X112   to match the direction of the transfers, the hint offered in the inspiration source can be followed down to indicate the first row of transfers need to be made to the right,    hence the knitting begins with the knit carriage on the left, the lace carriage on the right. As the LC moves to the left it preselects needles, and as it returns to the right it transfers them to the right.
The LC is removed from the knit bed.
The KC knits a single pass to the right and remains there.
The LC is returned to the knit bed on the left, preselects needles on its pass to the right, and transfers them to the left as it returns to that side, and is removed from the bed.
The KC knits one row to the left and stays there.
The LC is returned to the bed on the right and the process is repeated.
Preselection of needles is made by the LC toward the knit carriage, transfers are made away from it.
Whether the repeat needs to be mirrored again may depend on the machine model or the software used to download the file to it.
The direction of the first row of transfers provides the necessary clue, they need to be to the right. If to the left, mirror the pattern horizontally and begin again.
The swatch was knit in a wool-rayon blend, the results point to the difference in appearance and gauge with a change in color and type of yarn used when compared to the inspiration image The context for this can be found in To mesh or not to mesh 8: more Numbers meet Gimp

Blistered dbj 3

Names referring to the same knit fabric can vary between machine manuals for specific models and brands or references in books, magazines, and articles depending on the dates they were published.
My earlier share on the topic:
Blistered stitches dbj 1
Blistered DBJ 2 and technique variations on a single repeat, introduced some of the concepts involved.
Beginning with any random published repeat can offer the start of exploring a range of fabrics. This was a Pinterest punchcard share, markings indicate it was intended for Brother machines  Methods for obtaining color separations for specific knits have been discussed in other posts.
Brother models can use the cam buttons to perform a function in one direction only, ie by using only one tuck or slip button, the machine will knit when the carriage reverses movement to the opposite side.
Developing specific color separations makes the files usable on other machine brands and models, makes it easier to return to specific rows in error corrections, and is my personal preference in test swatching and complete pieces.
Drawing the initial design in repeat provides a visualization of the resulting secondary shapes and the number of needles required for tiled variations in finished pieces based on gauge.
The first design is intended for use in every needle rib, with the knit carriage knitting in one direction, and using slip or even tuck in the opposite direction.
The 24X32 design extracted from the inspiration punchcard  A: the rendering scaling the design twice in length
B: making the choice to color invert it in planning slipped stitches on the larger number of white pixels
C: superimposing black lines on every other row beginning with row 2 A quick review of the steps involved in working with Gimp:
begin with magnification for easy viewing, ie. 800X, view grid if preferred
the starting brush can be as small as this 2-pixel   select it and save it to the clipboard by choosing copy visible, making it available to bucket fill images, or export the same design as a .pat file and save it in the appropriate settings folder for future use.  A: the original design repeat rendered in black and white
B: layer, transparency, color white to alpha
C: file, new, white ground, matching size, filled with a pattern of pairs of horizontal all-white pixel rows beginning with white on row one, followed by all-black pixel rows on row 2
D: copy B and paste it on C, and export the file as png The chosen repeat may not be color reversed after programming it using the machine’s built-in electronic functions.
White pixels slip, stitches on the main bed in non-selected areas would not knit off for extended periods ie where red marks occur, and noticeable problems would develop quickly Beginning proofs of concept for this version, 24X64  knit on 60 stitches using it drawn in repeat X3, 72X64, and programmed as a single motif  The result is a very subtle contrast lacey knit The yarn thickness and color were changed. The pattern begins using the slip setting and transitions to tuck, also in only one direction. Because the ribber is knitting every stitch between stitches on the top bed holding side-by-side loops down, tucking on multiple side-by-side needles can be performed,  producing a wider, stretchy knit that also lies flat.  True blisters/pintucks generally knit rows on the top bed alone forming pockets that are eventually sealed by all knit rows.
Slip stitch settings are used.
The design is at first lengthened X5, then every 5th row is filled with black pixels or punched holes.
A begins in smaller groups of gathers, testing for any errors or problems, while B allows for deeper folds. A: the mark shows the stitches on the top bed begin to slip far too many rows
due to using the color reverse option in the 930 before continuing to knit.  With a switch to the blue yarn, all-knit spaces between the pockets now begin to appear gathered. Slip stitch results in narrower knits, noticeable in the ruffled effects on every needle rib above the cast ons B: the extra row of slipped stitches result in a far more textured knit   Developing other layouts for the same design, brick 24X128   half drop 48X64 Eliminating unwanted extra stitches from the original, modified to 24X28 pixels drawn in repeat to 144X168 brick version 24X56 half drop 48X28  adding those all knit rows  Viewing repeat alignments  The 24X112 brick repeat suitable for punchcards, not tested,   and the half drop, 48X56  tested using a 10/2 cotton and lightly steamed and pressed.

A collection of geometric design blocks built with squares, rectangles, and lines

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

ArahPaint in knit design 4

Reviewing ToolsGuess weave from Grid
ArahPaint continues to be user-friendly for multiple applications including knit design.
The developer shares how-to videos that are frequently updated
https://www.arahne.si/public/news/
https://www.youtube.com/@arahpaint4/videos
The same holds for their downloadable manual, and any questions are answered in a timely and informative manner.
I am often driven by knit technique curiosity first, then find myself circling back periodically to program explorations to shorten the process for drafting blog charts and repeats, sharing new information as I notice it in manuals or online.
A recently reviewed https://www.arahne.si/tutorials/how-to-import-old-pattern-drafts/ led to my first experiment.
When using the weave guessing function, it is good to know that the program looks at the center of the grid, and tries to ignore the grid itself. If the center is not a single color and is homogeneous, use averaging to smooth it out before color reduction. If it is not filled properly, use contour operations (thickening) to make it stronger.
When guessing the grid, make sure you use the “preview” function, so you see what the program sees.
The steps, relatively “winging it”:
as in resizing/scaling any design, accurate cell/ anticipated stitch and row counts are needed. They may not be given in the source, where grid properties, cell shapes, and colors may all vary.
For example, the grid in the original may be 6X6 for punchcard designs, 10X10, or even 5X5 for electronic models. Recognizing the blocks used aids in examining and adding up counts when they are not provided.
Load the selected picture, in this case, a random RGB one from a previous post, known to measure 24 stitches by 60 rows: Go to colors, and select convert to 8-bit palette,  resulting in these changes in the palette window on bottom right corner  Before reducing the number of colors to 2, adjust your background and foreground colors. Without disturbing the 0 value,   use the shift key and with the mouse select a light color from the 8-bit values, it will replace the #1 value.  Return to colors, set the number of colors to 2,
Magnify the image as needed, and use the rectangle select tool to eliminate the dark frame. There will be a dotted color dashed outline that can be adjusted,  use Image/ Crop to the selection to eliminate the unwanted border.
Select Tools/Guess weave from grid, and a new window will open.
The program automatically defines the size of the original pattern. If the value is not the expected one, enter the desired pixel counts, and click OK.  The “weave” will appear on top of the original pattern, surrounded by a bounding dashed line,     choose Image, and Crop to the selection, and save the picture as PNG. The result matched that in the previous post, with the Gimp chart on the left, and the Arah on the right. Check that the final PNG is in indexed B/W before any electronic download.  Select OK, Close, and save.  The Threshold adjustment slider is found in the reduce the number of colors window and may be used to alter B/W images at any point in image processing.
In addition to using Image/draw in repeat to check alignments, the View Repeat option will tile the design an arbitrary number of times automatically, providing a large-scale view, illustrated only in part on the right in the image below. The process is repeated with pattern #42, 46X56, from a Brother electronic pattern book:
the original is on the left, the ArahPaint guess grid result is on the right, colored differently to make it easier to check for matches and any pixel placement differences,  its B/W png.   The steps again with #3604, 24X240, once again comparing Gimp results to those obtained with ArahPaint  One of the challenges which can appear to varied degrees when converting files is the amount of pixel cleanup required on the resulting images.
One contributing factor that may be encountered is that the original to be processed may be askew, as only slightly in this image, #26 from the Brother 270 collection.  Using the unskew tool is one manner to fix the geometry of a layer distorted by perspective. Rotation may also be used.
Make a rectangular selection around the object which you wish to unskew.
Click on the Unskew tool  Drag the corners of the selection to the distorted part of the image, they are marked by hollow squares at each corner Click OK in the Unskew dialog box The selection becomes a normal rectangular layer. If uncomfortable working with layers, click on this tool to fix the image and remove the bounding box  Repeat the process already described, reducing the number of colors to 2 after cropping to the selection, the dark squares are not a true black. If the png is to be used for download to an electronic machine, change the grey to true black before saving.
The original, followed by the ArahPaint result and a tiled view of it The same approach may be used on large nonrepetitive images.
Hand-count the number of cells in width and height if they are not provided.
A scan from the Dover publication on Celtic charted designs, converting this 73X54 image proved easy.  The scan of a 130X95 stitch/row count chart from Charted Peasant Designs from Saxon Transylvania posed some issues.
The problem, in this case, was not the use of the basic technique, but that multiple areas of the chart were not marked with the black contained within grid cell borders.
Cropping problem areas, processing them separately, and pasting them in place on the previous result where needed appear to greatly reduce final pixel cleanup.  While weaving and many needlework drafts are often represented on square grids, some knit designs are published to reflect the fact that actual knit stitches with the exception of garter stitch are typically rectangular.
In the early days of electronics, knitting machine models began to have libraries of stitch designs stored in memory, cassettes, or floppies. Often manuals or booklets were printed as companions, visual guides to stored contents. Colors and counts did not matter, since the intent was not to provide reproducible designs.
This chart is from Studio, published as a tuck pattern.
My best results were obtained after cropping the original to 74X60 unit counts and scaling the scan’s A: 1733X992 to B:1320X960, a multiple X16 of both values.
C: the result of reducing colors to 2, followed by guess weave-from-grid for a successful match to the original, a final 60X48. The png would need to be color inverted for use with the tuck stitch setting. The png, after removal of a few wayward pixels, and color inverted for use with the tuck setting   Returning to that griffin, after resizing/scaling the original to multiples of 11, 1430X1045 pixels, the left portion of the design produced a clean match to the original, while the right segment with the off-grid dark cells still did not. The previously separately reduced segment was added on the far right yielding a far closer match.  Weaving and cross-stitch libraries offer a huge range of potential design repeats.
Some resources:
Weaving library: fressinet offers images in black and white
Patternbase: from Dictionary of Weaves
Archive.org: filet crochet

Beginning with a design selected from p.83 in the Dictionary of Weaves Color convert to 24 ->8, an expanded palette will appear. Press the Shift button and click inside the picture to manually select the colors, adding 63 in this case
Filters menu: choose Averaging, and follow with the second choice Repeat the last operation X10
Colors: set the number of colors directly to 2
Guess weave from grid to 18X18
Crop to selection, magnify and check results
Convert to black and white if needed
Check repeat alignment   Other ways to handle the same task: another ArahPaint tutorial offers additional tips.
From the Cross stitch book, a 40X40 chart using a straightforward setting of the number of colors to 2.  One way to convert the picture on the far right to black and white prior to saving it other than adjusting the palette colors is to use Threshold to reduce the number of colors.
1: select Black white, and Preview in the associated window
2: if an adjustment is required, the slider may be moved to the left or right, Undo if needed, and when satisfied stop
3: click OK and close the window, save the picture as bmp. An earlier design intervention for the final B/W png: after setting the palette to 2 colors, reduce the number of colors with the same 3 steps using Threshold for another successful result. Reducing the number of colors window instead of setting the number of colors to 2:
Color convert to ->8, an expanded palette will appear
Choose Averaging, and follow with the second choice, Repeat the last operation X10
Open the Reduced number of colors window  Press the Shift button and click inside the picture to manually select the colors for foreground and background, this did not work for me on my Mac with the latest OS. Selecting colors manually from the expanded palette by clicking on them is an alternative. The higher contrast between the two the cleaner the results.
Select Preview, if satisfied Click on OK, and Close
Select the whole picture
Guess weave from grid
Crop to content
Magnify, evaluate the results, adjust the palette to BW if needed, and save  Filet crochet pattern books also provide gridded sources that may be used in knit design. This 43X43 pixel file is adapted from Priscilla filet crochet book #1
The same process may be used on color separation templates produced in DAK

From a random Pinterest find with an original 330X474 RGB chart:
A: guess weave from grid, crop to selection
B: tools, find repeat, crop to selection
C: the final 47X46 png drawn in repeat  Adding colors to black and white pngs following the tip by the developer in the post comments:
Choose a black-and-white repeat, in this case, a 36X9 pixel repeat  Double-click on one of the two colors to protect/lock it Double-click on it again, and the lock disappears, the color is no longer protected.
In the palette, use + to add a new color, this may be repeated more than once to add more colors or go to colors, set the number of colors to a number, ie. 6, for a random palette group that may, in turn, be edited to other values.   Double-click on the rectangle tool to draw filled rectangles  In rectangle options, above the palette icon, there are toggle buttons for Horizontal and Vertical, remember to protect a color  Once your selection is made, draw the filled rectangle across a selected width and height while keeping the protected color intact. Draw the result in repeat to check for alignment the protected color may be toggled to white  If the designs are to be programmed for multiple color slip stitch or DBJ there are rules to be observed, and there may be restrictions on whether each palette color will be recognized as a third or fourth color by the download program ie. when using Ayab, where no two colors may occur in the same range of 8-bit values. For 4 colors, the ranges would be 0-63, 64-127, 128-195, and 196-255.
The img2track partial window with the associated color assignments for the first vertical variation.  The horizontal choice allows one to play with selections possibly matching yarn colors in fair isle knitting,          only 2 colors per row may be used, here the A feeder yarn remains fixed Remember to unlock the previous color choice if protecting new segment selections.
Visualizing possible FI striping results in progress Working with diagonal patterning in machine knitting introduced some approaches.
Following guidelines in Easily generate random weaves it is possible to quickly generate DIY designs for use in multiple techniques.

To begin with, load a new picture 12 pixels wide and one pixel high
Set the number of colors to 2, black and white if the goal is downloadable pngs.
Fill in a repeat, and multiply it by Y multiple times to achieve the final number, or fill in vertical bands using the pencil tool on the final planned starting canvas.
A single row repeat first multiplied Y X6, then X2 Select the measurement tool: The tilt tool shifts every next line of pixels, the width of the line in the X field for the horizontal tilt, or in the Y field for the vertical tilt Default values are set to 0 The selections for this design:  The resulting file, also shown drawn in repeat: Two more, with a starting picture total height of 24 pixels One repeat, multiple height selections  This repeat may be used for tuck or slip stitch, providing the final png is color reversed. The 12X24 initial result was multiplied X2 in height/Y to produce the 12X48 one. The image on the far right checks alignments Working in multiple colors using the same approach: These charts continue to use the selections with reverting back to the original after each variation, though steps may be made sequentially and reversed in a matter of seconds Any results may be modified by adding other program functions to produce drafts of expanded repeats ie. through using drawing in repeat/ random. The results may be suitable for large pieces ie blankets and likely best knit as DBJ.  The ease of designing needs to be paired with good notes on charting cause and effect and an understanding of the relationship between pixels/ punched holes and stitch formation using varied cam button settings.

 

Blistered DBJ 2 and technique variations on a single repeat

Blistered stitches DBJ began to explore some variations for the production of easy knits which resulted in pockets separated by areas of joined stitches, and depending on the design and whether one bed knits more stitches and rows than the other, can make the surface appear 3D to varying degrees.
There are several things to consider in DIY designs.
In my recent browsing and being inspired by “The curse of truchet tiles”, this png was one of the resulting repeats, developed using ArahPaint.  It is larger than any previously tested with this technique.
Beginning with a 36X36 file drawn in test alignment to 108X108,    expanding the design through a diagonal choice into a 72X36 repeat  Large repeats require large swatches if gauge matters, but smaller tests serve well to evaluate tension and cam settings. It is a good idea to be consistent in yarn choice.
Thinking things through:
the white pixel areas will produce the pockets, separating from the ground, and the black pixel areas will compose the joined portions of knit.
To increase the effect, the height of those black pixel areas is reduced by changing their configuration in order to use the slip stitch setting to shorten them.
The first pattern fill requires doubling the height of the whole repeat in order to use the file in a tubular setting.  Rather than doubling the file in height, this brush is used to fill the same black pixel areas. After a few pixel cleanups, this is the final repeat, The png was tiled to the number of stitches planned, with the addition of a knit stitch border along each vertical side and knit on 88 stitches for proof of concept.
End needle selection is on.
The carriages are set to slip in opposite directions, in either arrangement A or B. In one-color knitting starting preselection side does not matter.
The tension used, since so many stitches will be knitting on alternate beds, needs to approach that used for the same yarn when knitting stocking stitches.
The red yarn stitches mark the knit side of the fabric.
The cotton ball illustrates the formation of pockets.
The color change happened when the first cone of yarn ran out.
The yarns are 2/28 Italian imports of nonspecified fiber content.
The piece measures 10.5 inches in width.
When the settings are changed from tubular to every needle rib, the fabric is considerably wider and ruffles as seen at the top and bottom of the swatch, which could become a planned design feature. A segment was cropped from the 72X36 drawn once more in repeat to 84X72, repeating the same steps for processing the file alignment check If the plan is to evaluate the effect of tuck stitch on the design, to begin with, the file needs to be color reversed, whether in the drawn png or using machine settings Exploring results with the ribber set to knit in on every row, the swatch below the red line was produced with the knit carriage set to knit in one direction, tuck in the other, while in the remainder the knit carriage set to tuck in both directions. The areas that in slip stitch would form pockets knit in every needle rib, while tuck stitch segments produce a lacy effect.  The same design, using the png created prior to color reverse, set for tubular slip stitch the transition between the changes in knit carriage cam settings results in changes in textures and added width The full tuck section (bottom) measures 16 inches in width, and the slip-stitch one (top) measures 11.5 inches.
Trying for a half-cardigan repeat with the same yarn produced an extremely wide knit with no discernible design.
Tired of double-bed knitting and swatches in a single color and large enough to cover pillows? the starting image reduced in size X4 to 21X18 pixels opens a new series of opportunities for knitting including on the single bed.  The design, knit here as DBJ, uses the built-in KRC color separation. At the bottom, the knit carriage is set to slip in both directions. The ribber uses the birdseye setting in both directions with the addition of lili buttons.
At the top, the knit carriage setting remains unchanged, and the ribber is set to knit in both directions, for a striper backing. The tension remained unchanged. The image illustrates the difference in the aspect ratio of the design and the height and width produced by the respective settings. The same design knit as single bed fair isle produces problematic floats on the reverse which would need to be anchored down in a wearable. When knitting fair isle end needle selection is used to keep the yarn in the B feeder anchored so as to prevent any separations along the vertical edges of the design.
Here the light color is 2/8 wool. The yarn in the B feeder is switched to a 2/24 random contrasting color, and the knit carriage is set for thread lace. The white pixels knit both yarns together. Programming a blank row and knitting 2 yarns in this manner is considered by some an alternative to using the plaiting feeder.
End needle selection is canceled. If needles are brought forward, push at least one back to B so the combined yarns knit. In a long piece, a repeat in the width of the planned number of stitches could be planned with one or two blank pixel borders on vertical sides.
Due to the contrast in yarn thickness, the thin yarn creates large stitches that bulge in areas where it knits with the thicker yarn floating behind it, and the areas with combined yarns recede.
The areas in double thickness secure the yarn that produces floats, so that the latter may be trimmed on the purl side, leaving cut ends in any length. When cutting floats, consider sliding something under them and the thin knit so as to avoid cutting it as well, the fabric will release and flatten. Using elastic, the background yarn used needs to be thinner, here a 2/20. The repeat program is left unchanged, but the position of the yarns is swapped so the elastic/ “thin” is placed in feeder A and the white/ “thick” in feeder B. There is a considerable change in size, observable at the top of the previous images.   Aiming for float control, the repeat is edited.  A test of the 18X9 repeat using the fair isle setting measures 6.5 inches in width,   while the same stitch repeat knit using elastic and the thread lace setting adjustments once more, measures just under 2.5 inches in width 

Developing tiled repeats suitable for multiple stitch types, including tuck

Punchcard machine users have limitations in terms of repeat width, depending on the brand and age of the machine. Those numbers might vary from 8 to 12, 18, 30, and 40, with a 24-stitch width eventually becoming the most frequent.
When electronic machines were first released decades ago, multiple built-in functions allowed one to manipulate programmed repeats. The latter were drawn with electronic pencils (Studio) or far more often with permanent jet-black ink on mylar sheets or “cards”. Passap at one point developed the initial Wincrea version with a very short dongle for downloading designs to the console away from the knitting bed.
Brother was the first manufacturer to allow programming multiple repeats on a single mylar sheet. It took Studio some time to play catch up to eliminate all the potentially wasted space on them.
Both brands used mylars with 60 rectangular cells in width by 150 in height.
Variation buttons for the Brother 910, for those not familiar with its options.  Building up a simple angular repeat can easily be done freehand filling in pixels, or with the use of the straight line tool in ArahPaint.  The 12-stitch design may be mirrored and rotated in a variety of directions. For use in a punchcard, this may be done once in width, and three times in height to meet the minimum length requirement.
It is not necessary when drawing to use only black and white to start with, though if the goal is ultimately to produce a programmable bmp or png, the final images need to be in those 2 colors.
It is easier to produce a design filling in fewer squares in lesser density and then to color reverse the results if that is required for the specific stitch type.
A: using horizontal and vertical mirroring yields the start of a diamond shape. Punchcard users may find it easier to mark the dark squares and punch everything else if the goal is to use the tuck stitch setting or to have a card “safe for everything”
B: checking alignment by tiling the file
C: if the intended goal is tuck stitch, and the minimum information is drawn in the design, then the repeat must be color reversed, whether in the program used to create the file or by selecting the built-in function in an electronic after download.
D: the color reverse image tiled, may be suitable for some interesting fair isle striping or exchanges of positive/negative spaces at the intersection of any of those rows where the double-height or double-width markings occur.
Red cells indicate two side-by-side unpunched holes or unmarked pixels. In theory, this breaks the tuck rule requiring a knit stitch/ unpunched hole or black pixel on either side of an unpunched area/white pixel, but it likely will be fine, producing something that looks more like a slipped stitch than a tuck.
The double-height areas marked in green would be a problem if one were to test the repeat by doubling its length, with a compounded issue in those areas where tuck stitches would then happen on side-by-side needles for 4 consecutive rows.
Usable with some care for knit weaving, slip stitch, and other stitch types. Results are not discovered unless actually tested.
Keep good notes. Breaking the design into segments to knit as a striped fair isle ie in these 4 places Variations are easier to imagine if one begins with colored repeat segments that can, in addition, be varied using color exchanges to resemble approximate yarn colors. Instructions on color banding using ArahPaint follow at post bottom. In the last post, the same image was mirrored using ArahPaint  The result is a 23X23 pixel design.
Any incrementally larger repeats would require the same operations, using the mirror X-1 and Y-1 options to avoid any side-by-side equal cells, but the process is easier with some understanding of isolating repeats. When the 23-stitch file has been formed, manually trim one pixel along the bottom or top row, and one along either the left or right side, down to 22X22 pixels tested in B/W repeat and here color inverted it is executable in double length thus offering the opportunity for color changing every 2 rows, testing the possibility of its morphing into a mosaic/maze design, remembering first to color reverse the repeat as given here,  which in turn yields a file that may be knit with color changes every 2 rows, a technique that can produce maze/mosaic designs with an appearance very different from the same pattern knit as fair isle.
In this swatch, 2/20 wool yarns were used. This results in a knit that can be steamed to stay flat.
The variations in the amount of tucked stitches and their placement expand in some areas more than others yielding wavy vertical side edges.
The striping occurred to enhance the visibility of stitch formations on the machine, but can be a deliberate way to add even more colors to such pieces. The same design, knit in 2/8 wool, begins to show that a pattern may produce very different effects with a simple change in materials or color choice Working outside straight lines and exploring random starts: the post Working with diagonal patterning in machine knitting introduced several larger initial repeats also suitable for tuck patterning when reversed, including this 12X24 pixel design,    and the companion larger file, 144X144 pixels The larger file can serve as the start for exploring knit pattern variations through the use of filters.
Beginning with zig-zag, the description from the ArahPaint manual:
the Zigzag filter creates a zigzag from the image. The number of zigzags depends on the setting of the filter option (X, Y, and Value) and the direction (Horizontal, Vertical, or a combination of both).
X: determines the number of zigzags up and down, the number should be an even number ie. 144 divided by 12 would create 12 peaks
Y: creates the vertical direction of peaks
Value: set to 0 the whole image height is taken as amplitude
The variations can be endless, and exploring changes in settings will help develop a sense of what happens. The larger scale results may at times be reduced to a significantly smaller working repeat. Tools/Find Repeat often but not always will do that seamlessly.
The manual offers instructions for manipulating vertical bands of color. Such variants could be knit as intarsia or multiple colors per row, with limitations and considerations.
This 4X4, vertical repeat, tiled to 12X12 color reversed for tuck knitting drawn in repeat and filtered is knittable, but not interesting to me. The result, shown tiled for clarity Moving away from straight lines, these initial experiments employed limited variations. The red X mark marks the repeat suitable only for fair isle knitting Choosing individual results to knit in tuck stitch, in review: the smallest repeats may be isolated and pixels cleaned up if preferred, remembering to color reverse when needed. This 24X24 repeat is suitable for punchcard models with the black pixels areas punched. Testing is far easier and quicker using electronic machines, do not use double length The design is asymmetric, subject to personal preference, and as usual, with results dependent on yarn and color choice.
The yarn used at the top of the photo is a wool-rayon, knit single bed. It was hard to identify stitch formations, hence the swatch was short in height for a visual texture check. Because of the rayon content, all edges steam and press fairly flat.
The other yarn is all wool, knit in every needle rib with the knit carriage set to tuck in both directions, and the ribber carriage set to knit in both.
This type of knit is often referred to as pick rib. Depending on the tuck stitch distribution, the stitches are forced apart vertically and can produce an eyelet effect in a fabric that lies quite flat. A closer look at approximately the same part of the ribbed fabric.   A 58X16 file after some cleanup and cropping of one of the other variations is to be color-reversed for use with the tuck setting. Depending on the thickness of the yarn, double length may be used safely for added texture.  The swatch illustrates the difference between fair isle knitting and tuck stitch, even when the tension used in the knit carriage remains fixed. Fair isle is in the slip stitch family, so it is short and narrow, while tuck stitch tends to be short and wide. It is usually recommended that fair isle floats be no wider than 5 pixels. Many here break that rule and would need to be managed if the design were to be used in a finished garment.  This segmented and cropped to 17X144 pixelsMirrored X-1, 33X144 pixels I like to plan repeats for any intended piece when possible in a width matching the number of needles in use, which allows programming as single-motif in the 930 with img2track and eliminates the need to turn on other built-in functions or assign needle positions. Doing so also offers the opportunity to add borders if desired.
A 99X144 version was programmed, and the central 71 stitch width was tested, likely suitable for an accessory ie a scarf  Those side-by-side white pixels are “OK” since they are in turn sided by black pixels and do not repeat for more than 2 rows.
At some point, one needs to commit to actual knitting. The first proof of concept swatch was knit in a softly spun, shiny rayon that had a slight tendency to split during knitting and steams and sets nearly completely flat.  This swatch is knit using a 2/8 wool, retains its texture after steaming and pressing, and exhibits the usual roll to the knit side at the top and bottom of the piece, and to the purl side along the vertical side edges. The variations in the 3D surface that can happen with some tuck patterns appear here and are retained.   Restricted use images may also be built from scratch.
Large published illusion-style designs even if beginning as black and white when scaled down in size can lose definition as a result rendering them speckled, needing a lot of pixel cleanup, or completely unusable.
This first attempted DIY version begins with a 31X31 repeat. The odd number allows for a corner-to-corner start. The lines are drawn using the straight line tool, with pencil size alternating between one and 2 pixels Using mirror X-1, Y -1 to 61X61 trimming by a single pixel and width and height for routine tiling avoids lots of doubled pixels. The final repeat, with small single pixels placement edits, is now 60X60  repeated in height only it could be used for perhaps a scarf, with or without solid borders at the bottom, top, and sides.   Drawn in repeat X3 in both X and Y directions it produces a 180X180 file large enough for a blanket, with a bit of wiggle room to add a narrow solid color frame if desired.      The design may be knit as fair isle for a quick initial test or for a final piece since the floats are all very short or knit as DBJ to produce a no-roll final fabric without floats.
In this test, softly spun rayon and heathery wool were used, resulting in a surprising color mix when compared to their original colors. There were a few spots where the rayon fiber split and knit with the contrast. The end needle selection was off, so there are tiny eyelets in some places where the contrast was not knit on the side edge, and the fabric separates a bit.  A variation for a different vertical repeat can easily be isolated from tiled drawings. This additional sample was also knit as a fair isle, with end needle selection on. Suitable for punchcard knitting: a 12-stitch simple geometric repeat visualized X12 modified using drawing X12 in random repeat for electronic machines.  An 18-stitch repeat visualized X 9 modified using random   A 24-stitch repeat accomplishes an optical illusion of sorts. If only it would work for creating origami-style pleats!

44X54Adding colors to black and white pngs following the tip by the developer in the post comments:
Choose a black-and-white repeat, in this case, a 36X9 pixel repeat  Double-click on one of the two colors to protect/lock it Double-click on it again, and the lock disappears, the color is no longer protected.
In the palette, use + to add a new color, this may be repeated more than once to add more colors or go to colors, set the number of colors to a number, ie. 6, for a random palette group that may, in turn, be edited to other values.   Double-click on the rectangle tool to draw filled rectangles  In rectangle options, above the palette icon, there are toggle buttons for Horizontal and Vertical, remember to protect a color  Once your selection is made, draw the filled rectangle across a selected width and height while keeping the protected color intact. Draw the result in repeat to check for alignment the protected color may be toggled to white  If the designs are to be programmed for multiple color slip stitch or DBJ there are rules to be observed, and there may be restrictions on whether each palette color will be recognized as a third or fourth color by the download program ie. when using Ayab, where no two colors may occur in the same range of 8-bit values. For 4 colors, the ranges would be 0-63, 64-127, 128-195, and 196-255.
The img2track partial window with the associated color assignments for the first vertical variation.  The horizontal choice allows one to play with selections possibly matching yarn colors in fair isle knitting,          only 2 colors per row may be used, here the A feeder yarn remains fixed Remember to unlock the previous color choice if protecting new segment selections.

More Truchet inspired tiles, a brief look at gradient filter use


The latest ArahPaint user manual download,  updated on February 9, 2023, includes added directions for drawing in repeat including a truchet/Smith tile variant.
This post will not provide specific how-tos, the pngs can be downloaded and used to perhaps test Arah’s features or to aid in finding a personal, preferred method for manipulating DIY designs.

There are additional Arahpaint options for altering designs in width and height which may be used progressively on the same image. Some in the group of edits and rotations are evocative of the Passap console’s Alter programming loop.   Lower in the same menu, diagonal mirroring opens yet another series of possibilities. These samples were produced in a Passap workshop, using the console Alter, add commands. Note that mirrored areas have identical pairs of side-by-side pixels at their meeting points,  while ArahPaint offers an opportunity to change that, a thing to keep in mind when returning to simpler motifs such as those used for tuck stitch. Performing the rotations, however, will render the result with an odd number of pixels in width, often making them less likely to be usable in punchcard models  My area of interest has been primarily and still is in creating textures beginning with small repeats that may grow in complexity and size to make the structures programmable and thus easier to track and execute.
Presently I rarely engage in multiple color motif work ie fair isle or other large-scale textile pattern applications but my curiosity in applied techniques has led me down this potential giant rabbit hole.
The speed and ease of drawing variations for repeats using ArahPaint make the process addictive.
The source of inspiration for this design series is “The curse of truchet tiles”.
When recognizable circles are a goal, these tiled motifs often begin with starting sizes as wide as the 24-stitch standard punchcard repeat limitation, and the manipulated larger motifs are suitable only for electronic machine models capable of accepting software downloads. Adding lines and extra dots of circles
Isolating fractions and individually rotating segments to draw again rendering larger repeats More info on knitting DBJ using more than 2 colors per row:

Adding one more color to the last repeat whole planning a knitting a test at a max of 3 colors per row knittable in a single track 
The img2track window Positions of the respective yarns in the color changer as suggested by the program result in accuracy prompts by the machine on which of the respective colors should be in use at any one time.  Planning gauge-dependent pieces using large repeats requires large test swatches, generally a minimum of 100 stitches by 100 rows.
Adding and varying the colors in the design draft to match the yarns to be used in the repeat helps to visualize the possible result, and allows for using the sequence suggested by the download program to help track the proper color changes.
The test here is 60 stitches wide, knit one full repeat in height, measuring 7.5 inches in width by 11.75 inches in height after resting. On rows where the colors for the dots and squiggles may knit in small parts or not at all, there will be a preselection of large groups of needles such as seen here.  Birdseye setting is used to decrease motif lengthening. The img2track user manual describes the steps necessary for downloading to different model knitting machines and possibly using more than single tracks. A series inspired by another of the tiles in the linked publication   
Similar to one of the source repeats, increasing the balance between light and dark Open areas or specific rotations in the visual space may be created by eliminating or rotating individual segments.
To change the mirroring type, place a mouse pointer over the arrow that you want to change, and press the left mouse button. The arrow will jump to the next mirror type. With only 5 mirror types, you will get what you want in a maximum of 4 clicks. If you press the right mouse button, it will put the arrow to the default orientation. The result of course is dependent on the original file choice. Combining duplicating repeat variations with drawing in repeat helps one develop a DIY library of favored tilings. Begin with a possible background Tools/ Find Repeat  Aiming for knot variations, a cross-over to add to segments of the ground, manipulating individual tiles, adding copy and paste More play with manual duplication of tiles as opposed to drawing in repeat Combining different scale repeat segments, starting with 54X36 pixels  And it’s not all about just circles, a 36X36 pixel design to play with A reminder, if the plan is to add color in continuous lines, it is best to place the colors after the full design repeat has been developed rather than on the individual starting tile segments, For some, this would be considered a design feature.  A very different look may be achieved using any of the available filters. A square image of any size may be filled with a color gradient while keeping in mind the fact that knitting is very low resolution and the maximum number of available needles for patterning is 200 or under.
Beginning with a 20-stitch file. Below the software tool options on the right, click on the tool in the area marked with the red shape to produce a design that may then in turn be drawn in repeat No edges were cleaned up in this view. The design meets the maximum 200 pixels/needles size Going larger, an 80-pixel start to end with a 160-pixel blanket or tapestry suitable image with some wiggle room for adding a frame/border. The concept may be used in various densities for use in an accessory such as a scarf, spaced and colored to your liking, or even sweater bodies and sleeves planned specifically based on stitch and row counts for each of the pieces involved. Filters may also be applied in developing other stitch structures in addition to working with color motif designs. That topic merits its own post.
