Color separations for larger scale mosaics and mazes

There are generators online for many generators to aid with knitting design. In 2015 I published a post on working with generated mazes: Gimp charting 1
The mosaic and maze graphics prior to their color separations are not suitable for fantasy fair isle double bed knitting as a shortcut. There are simply too many vertical white pixel rows begging for carriage jams no matter the machine used. The same long lines of black or white cells make them unsuitable for traditional fair isle knitting as well.
Visual clues are helpful as steps get navigated. In small-scale repeats, a different option from the method that follows is to begin with a file previously used and separated, magnified to 1800X.
1. using the rectangle select tool, begin on row 1, extending handle outside the image, I work from left to right
2. hold down the shift key, and continue selecting every other row. As each row is selected, it is outlined with dots. The handles to the right and left of that row serve as guides as to the last row worked, moving up as separation progresses. Clicking on the rectangle select tool at any point fixes the layer, and the dotted lines will disappear. The process could be performed in steps, with guides placed prior to color inverting the previous steps in the sequence and moving onto the next. The guides remain until they are removed by clicking on the check mark beside show guides, or with the Image / Guides/ Remove all Guides command.
In large designs, I would guess this may be more easily error-prone than when using layers.
3. after each pertinent row has been selected, choose the color invert option, and save the resulting file. The first step is completed in the separation.
The file then needs in turn to be color-inverted and lengthened X2 prior to knitting. The result matches the separation in the previous post.   Holding down the shift key when using the pencil tool on any image produces very different results.  My samples continue to be knit on the 930 using img2track, a download program I find reliable and easy to use. The only errors in programming I have encountered were due to operator errors, not software ones.

Since 2015 working with larger images has become far less daunting as my methods for color separations of mazes and mosaics have evolved.
Laura Kroegler’s online Mosaic Pattern Generator is still available. Returning to it, and using these parameters the pngs were downloaded both in red and then again in black and white. A 38X38 stitch repeat was isolated, and using Layer/Transparency/Color to Alpha a knittable mosaic design was obtained which, when knit, would require elongation X2 for color changing every 2 rows The last file, doubled in length to 76 rows in height, requires no further processing The separations are achieved now in just minutes.
The proof of concept swatch: when using repeats that are so much wider, one must commit to far larger swatches to test them. In addition, the placement in the final piece may matter with shifting the pattern to highlight a preferred center, here the machine was allowed to place the design as a simple overall one on 78 stitches by 116 rows. There are droves of inspiring large-scale mosaic crochet images published nowadays, which led me to wonder about DIY similar large graphic mosaics in machine knitting.
I performed the first color separation with shortcuts, used mirroring the cleaned-up repeat, did not verify each step with tiling, and committed to knitting a test swatch. A 68X136 repeat X2 in width and at least with 40 more rows in height, produced a 16X24 inch test swatch, wherein a couple of missing pixels became noticeable.
The swatch was also knit using slip in both directions on the main bed, which produces a narrow, short fabric as opposed to wide and also short when using the tuck setting. Back to the drawing board.
The initial approach is similar to that used in creating mock filet crochet shapes on the machine.
With present tools the results process is easy and quick: to begin with, choose any symmetrical design where the shaping of the motif occurs in single rows, this one measures 23X23  scale the file X3 in both directions to 69X69 save this brush to use later for bucket-fill in the design.     Choose fuzzy select by color/black, each shape will be surrounded by a dotted line bucket fill the selections with the saved pattern click on rectangle select to fix the layer, work on and clean up the repeat, and check a magnified version for any missing or misplaced pixels.  Save the png. for reference before continuing to work. Make one of 2 choices. If the goal is to place a motif, and to add borders or horizontal additional design stripes, create a new canvas, larger in size than the above, fill it with the same pattern, and then Colors/Invert.  Click on the rectangle tool to fix the layer.    Change the white color to alpha in the previously processed snowflake, click on the rectangle tool again copy and paste the file onto the color-reversed grid, and click on the rectangle tool.  Check the pasted image visually, and continue adding any other designs.  If the goal is to produce an all-over design, crop the shape on the dotted ground, and save it as a 69X69 repeat. Pasting the original on an equal size color reversed dotted ground does not work.  Tiling the result of the cropped repeat will show the need for cropping it by one row at the top and one column to the right.   The resulting repeat, 68X68 tiled X3 in each direction for a visual check.  Using the process previously described
1. open the 68-stitch file in Gimp, and magnify it to at least 800X for a visible grid
2. open file/new, equal size and magnification
3. copy and paste 1 on 2, click on the rectangle select tool
Colors/invert, click again on the rectangle tool or anywhere in the work window 4: magnify further if needed. Using the pencil tool fill in every other row beginning with row 2 in a contrasting palette color, and click on the rectangle tool 5. Layer, transparency, color to alpha, as described in the last post, click on rectangle tool 6. Copy and paste this result onto the 68-stitch file in the first window, there will be lots of dotted lines onscreen  Click on the rectangle select tool to paste the image in place. Since those large areas of white will be knitted in a tuck or slip fabric, the above result needs to be color inverted. If used as is, set the machine’s built-in double-length function.  Doubling the length of the file prior to the download to km Part of the view on the img2track screen for the 68X136 file ready for download. Committing to proving the concept:  Using the same approach of tripling the original, here the repeat was used in an attempt to render a larger-scale mosaic. The process becomes fiddly because using the fuzzy select tool and then the bucket-fill-in pattern does not work cleanly on areas that are only 3 pixels wide.
That said, it is possible obstinately, in stages, to get from this, 36X54 To a 36 by 56 mosaic
A last edit Perhaps falling in the category of “don’t have to simply because I can”.

Images at this stage of the process may be knit double-bed as a “fantasy fair isle” with no further separation.
On an electronic machine, download the repeat, program it for the number of needles in use on the top bed, and select the KRC separation button.
The first preselection row will need to be from left to right.
The main bed is set to tuck in both directions, the ribber to N in both directions.
There will be lots of non-selected needles tucking on rows with large numbers of side-by-side white cells. Because the fabric is being knit using every needle on both beds, each main bed tuck loop will have a knit stitch on the opposite bed anchoring it down. Those rows will appear more compressed, producing narrower horizontal lines The yarns used were very thin single strands of  2/28 at tension 4/3. The result is a very lightweight and loose knit with lots of drape. The 72 stitches by 140 rows swatch measured 16 inches in width by 10 rows in height. Perhaps a good method for summer shawls, worth exploring in thicker yarns for blankets. A closer look at the structure:  A larger BW design was processed using no modification of the original 75X71 motif. When using Gimp/File/Save, the result is a .xcf document similar to PSD files in Photoshop. It will store layers, transparency settings, and more information associated with and parts of the same project. Note to self: before deleting the .xcf make certain that at least the final png has been saved.

If one is familiar with image processing and fond of the maze appearance in designs, there is a font to try: Mazeletter
The downloadable associated documentation and source for inspiration: http://mazeletter.xyz/Mazeletter.pdf.
A very quick random type sample rendered with no advance planning: 

Another, mosaic4way, is potentially usable for single bed fair isle or dbj.  The drawback has been that my sample pngs for both were created in RGB mode, and conversion to BW or scaling loses details.
It is possible to begin on an all-white canvas, set the mode to indexed to start with, type text, merge layer down, crop to content, and have workable indexed black and white knittable results, but the degree of success appears to depend on the font size used.
Another thing to investigate 😉

Gimp Update for Mac 3_more on color separations

The latest version Gimp Download site
I am self-taught. As I learn new tools, my workarounds may be convoluted and more complicated than they need to be and evolve with time. I do not delete older posts or their content, but do occasionally add links to later posts or dated notes.
I began designing and charting in the days of having to draw on graph paper and cutting up results to see if the repeats would tile properly when knit, or to place them for alignment variations such as half drop or brick.
Scanning amounted to tracing with a marker onto blank sheets of acetate or tracing paper.
The availability of commercial acetates for purchase at seminars, printed in pairs of matching horizontally striped sheets in lines separated in a variety of widths, offered an advance in scaling designs to a knit aspect ratio. Copy machines became useful friends.
DBJ designs in the punchcard studio, when I began teaching, were accomplished at first with the use of cards themselves as templates and overlays, involving a series of time-consuming methods for each type of separation ie.  So many such processes are now nearly instantaneous by comparison.
Earlier this year the post Using Layers in Gimp for color separations explored several fabrics beginning with B/W motifs.
Sometimes lightbulbs go off leading to other ideas for achieving results in quicker or easier ways.
This color separation method for mosaics continues to use Layers but in a different approach.
A spreadsheet may still be used if preferred to draw the initial draft of the design, working in black and white only would be fine, and the import could then be processed in Gimp.
Mosaics and Mazes are generally knit with color changes every 2 rows using either the slip stitch or tuck carriage setting in both directions. Beginning with any DIY or published design, to knit the motif using the tuck setting, there are basic rules to remember.
This illustrates possibilities using a random 6-stitch repeat, A.
If the plan is to set the knit carriage to tuck in both directions, the design would need to be color-reversed to B. The white cells in B represent loops held on corresponding knitting machine needles, the limit in Japanese standard machines is often 4. Black cells represent knit stitches, generally seen in groups or on either side of tuck stitches/ white cells, to anchor the loops down for proper stitch formation. There are some infrequent exceptions to that rule.
When uncertain as to results in developing DIY designs, begin with a published repeat to build up confidence. This is a hand-knitting resource for endless inspiration, no separations are provided in the book text.  There are always many ways to achieve the same task depending on the specific program used, one’s level of skill, and individual thought process.
This method uses multiple windows in progression.
When starting out, save the result in each step for added practice or in case any step is accidentally deleted.
This is by Kathleen Kinder, published in Floatless Fair Isle, p. 87 Though the final designs are saved as black and white pngs or bmps, to work using colors in separations, the mode needs to be set to RGB. For very small repeats, use view, show grid,
magnify 1800X, type in a number for a preferred value,  or use the command key in Mac and the scroll wheel of your mouse to do so. Using the pencil tool draw the repeat in black and white Selecting file, new, open a canvas in the same size and magnification, with each step a new icon appears at the top left of the Gimp window to select any file, simply click on the corresponding icon, use Edit Copy or command C, and then edit, paste or command V to place files onto new selections.
Copy and paste the first image onto the blank canvas and colors-invert the result  To draw straight lines on a Mac, use the pencil tool to place the starting pixel. Hold and drag the mouse to the desired endpoint. As this is done, a guiding line will appear. When the endpoint is reached and the mouse is released, that line disappears and the selected area will fill with the chosen color.
When using the 2-pixel brush, the mouse must be placed slightly into the second row of cells before dragging it for the line to remain straight and in the proper rows. If an error is made, choose Edit, Undo, to eliminate any step.  Continue to work on the color inverted file, and beginning with row 1 fill in every other row with a distinctly different color. To fix any layer before continuing, click on the rectangle select tool, and then again anywhere in the work window.
Getting rid of the red: this will be the immediate appearance of the image in the window, disregard it.
Right-click on Color/white, choose the foreground or background color or left-click on the Color bar, and click again to choose the color from the palette window. Choose rectangle-select cool, click on the result to fix the image, and the color window will disappear. The result: Copy and paste the file onto the initial image, there will be dotted lines upon the placement,  Click on the rectangle tool again, and then in the work window for the final png repeat. Change the image Mode to Indexed BW if its end use is a download to an electronic machine  Why is it different than the Kinder repeat? It is easier in drawing to color in white squares as opposed to black, so the repeat in the pub is the above, color reversed.  Punchcard machine users may mark the black squares and then punch all others.
The last step: if colors are to be changed every 2 rows, remember to use double length or to program/punch the last png double length.  An illustration for the full double-length punchcard repeat. The above, 12X36 repeat was color reversed and tiled twice to meet the 24-stitch width requirement. The 36-row height also meets the minimum height requirement for punchcards to roll in continuous patterning.
Mark the black cells in the image below on the card, and punch all the white ones. These fabrics are often more interesting using the tuck setting than the slip stitch one.
I have a lifetime supply of copper yarns from my jewelry-making days. This repeat is more a maze than a mosaic. Using a fishing line or wire can sometimes also produce interesting effects.
The blue yarn is composed of 3 strands of 2/48 cashmere/ wool.
The wire is a 32 gauge coated copper magnet wire which tends to flatten the final knit. On the machine, it is hard to recognize repeats due to the very short floats, and the unusual fiber rows can appear to be see-through Using a light color wool rayon as the second color. Using a separated 16X16 repeat from the 2020 post to knit a swatch for Instagram, I noticed a solid 3X3 block in the center of one of the shapes. Because the wire is see-through to some extent, the white stitch floats behind the blocks are noticeable. The copper wire used was 40 gauge, 3 plied. The higher the gauge number the thinner the wire strands, nearly invisible when threaded and while being used. Because the knit tension was as tight as possible, the stitch definition is lost in a few spots.
The original design motif, on the left, was missing a white cell in the location of the red cell. It was quickly converted using only Gimp.  Comparing the old repeat to the new, that problem pixel may easily be located. The corrected file before lengthening X2,  double length  Proofing a pattern is best done using comparable weight, familiar yarns. Here thin poly and 4-pound fishing line are used as the second color It takes a bit of squinting to see the match.  Testing the same repeat in more “friendly” and equal-thickness yarns This 24X28 repeat from the earlier post is reworked in this method repeating the process described here, it took longer to render the repeat than to perform the color separation.  The tiled alignment check
The steps are in sequence and produce a result matching that achieved in the previous post. A reminder: step #6 result would need to be doubled in height, whether by altering the file prior to download or by using the built-in functions in the machine after the download. The theoretical color separation to knit the mosaic as DBJ where each color knits twice, the repeat single length, 24X56 double length, 24X112

Double jacquard using punchcard machines shared manual methods for including one avoiding the elongation by matching the electronic built-in KRC color separation. Using Layers in Gimp for color separations introduced an approach using only Gimp.
There are times that the 2-color separation for DBJ which knits each color in each design row twice is necessary for the intended knit technique.
When testing new methods, one may begin with files that have already been proofed. This file is created so no elongation is required, beginning with the shape elongated X4.
From the layers post, the double-length separation where each color in each design row knits twice Duplicating the result using layer/ transparency  Longer repeats can become more complicated to separate. Testing the results by necessity requires larger swatches.
Using Stitchworld #548, a 24X40 repeat, as with mosaics1: draw the desired repeat in Gimp
2: when the drawing is completed, tile the repeat to check alignment, save the image if desired, or discard it
3: in the original window, scale the image to double its original height, now 24X80
4: using file, new, open an image on a white ground in the same size and magnification, a minimum of 800X, with grid view, as the first window
color invert
continuing on the same image, changing magnification as needed for ease of visibility ie 1800 X, choose a palette color, and using the pencil tool fill in every other row beginning with design row 1 using it
5. using color to alpha will remove the blue color in this case, and the image will change in appearance, the blue is now transparent. Copy the result.
6: use the second image, and paste it directly onto the one in the first work window.
For the repeat to knit successfully as DBJ, the resulting  24X80 file will need to be lengthened X2 to 160 rows in height for accurate patterning to occur. The design lengthened X4, using a 2-pixel pencil beginning on rows 3 and 4,
produces a 24X160 file that requires no elongation.  In this DBJ version, the first preselection row is made toward the color changer, followed by color changes every 2 rows.
My proof of concept is knit with the knit carriage set to slip/slip and the ribber setting left to N/N, creating long stitches.
The height of the design, any bleed-through, elongation, drape, and stretch, are variables influenced by carriage setting changes on either or both knit and ribber carriages.
By default, DBJ knitting requires many more carriage passes than 2 color patterns knit single bed as fair isle.
My swatch does not begin at design row 1 because I forgot to set the knit carriage to slip after the first preselection row and color changing on the left.  Scaling the knit for a sense of the degree of elongation The above separation is the default one in Passap knitting machines.
Japanese electronic knitting machines perform the separation where each color in each design row knits only once automatically by engaging the KRC function.
Punchcard users can achieve the same results for repeats that meet the width constraints using a maximum of 24 stitches or factors of 24 in width.
The separation where each color only knits once from the layers post began with the result where each color in each design row knits twice: My first effort using layer transparency to separate for each design row color knitting only once begins with the double length separation opened in Gimp, not necessary as seen in notes that follow.
Using the pencil tools, marking begins on the second and then even numbered design rows.
When # 5 is color reversed, it matches the separation using layers in the above far right  Using the same concept, the first test began with the separation already completed for the repeat that would knit each color in each row twice.
Toggling magnification helps to make the height of the repeat manageable. Errors are easy to spot and correct if noticed early, a few rows of pencil marks can simply be undone. Save the final png, also 24X160. The separated design is suitable for punchcard machines, my swatch is knit on a 930. Since these separated designs are programmed as fair isle designs, there will not be any color change prompts provided by some machine models.
The first preselection row, as when using the KRC function, is made from left to right. The knit carriage is set to slip both ways. The ribber carriage is also set to slip both ways on an even number of needles, and lili buttons are in use. The visual difference in scale between the two different techniques and color separations.  The simplified method begins with the original design scaled X2 to 24X80. The 2-pixel pencil tool is used to mark the resulting design beginning on rows 2 and 3, skipping the next 2 rows, and repeating the process
Committing to a larger test swatch: The repeat though successful in this case is different from half the first one obtained the long way, the concept merits testing with other motifs.   Years ago I shared the way punchcard knitters may create a DBJ card using a series of templates. The starting 8X8 design was often used in my 2 color DBJ posts. On the right, it is repeated across 24 cells, as it would be in a punch card.  Using layer/Transparency/Alpha the same results can as when using the card templates may be attained in just minutes. Here each color in each row would be knit only once:  In this case, the final result would need to be elongated X2 in order to knit each color in each design row twice. This separation requires no elongation. If the plan is to print a template to aid in marking a card prior to punching, one way to determine the required template size is to measure a punchcard with a ruler in mm.
The width of the card is fixed to a print width of 108 mm since the card will always be 24 cells wide. No calculation is required.
In height, the 60 rows on the factory blank card measure 300mm, 5mm for each cell.
I cropped the chosen image to the top 39 rows and scaled it to 108X195 mm.
(39X5).
When printing on US letter size, with no adjustments other than to the image, the limit appears to be no more than 45 rows per page. I was not able to print directly from Gimp.
The file, exported, opened in Preview, and then printed, is shown with a card superimposed on the printout over a makeshift light box, ready for easy punchcard marking even though the printed cells were not all of the same ink density.   

 

 

 

Another racking tale: Passap/Brother 5

I taught in a design school in a lab with Brother Punchcard models, four 910s, and 2 bulky machines. My previous experience had been using Passap and Studio electronics, and a crash course in Brother models followed my being hired.
My E 6000 was purchased from a sewing machine center at a time when the owner decided knitting was not for her.
The 560 Studio model was later upgraded with a change in their box in exchange for my publishing some patterns for the Studio Design Magazine but was sold years ago.
There were years the Passap was my production machine for garments and accessories knit double-bed. Single-bed knits for the same end use were easier to knit on Brother, with a clear view of stitch formations vs the issues with seeing the fabric or correcting errors when working with the ribber in place.
The immediacy of easy testing with img2track on the 930 results in nearly all of my recent blog swatches.
There are still days I admit I do love the E6. The console commands along with the lock setting and pusher options on the back bed make a range of fabrics possible that are far harder to achieve in Japanese model KMs.
Looking back, these are some of my previous shares including Passap mentions

FB shares have led me down rabbit holes I may not otherwise have entered.
In the machine knitting group, someone recently shared a series of scarves knit using the E6, providing the Duo80 diagram and the E6 technique number.  The setup is for a 2/2 rib, reverses the pusher positions, but produces the same knitDuo 80 symbols AX = Tuck, setting is the same in both the Duo and the Passap back locks
AX  serves the same function in the Duo, and is replaced by KX on the E6 front lock
The arrow keys on the back lock work the same on both machines.
Passap preselects and works on pushers initially placed in work or rest on both beds, whether manually or by console selections in the E6.
Brother preselects needles in the planned pattern on the knit bed subject to punched holes or programmed pixels, but not on the ribber, other when using lili buttons, and that comes with rules and the sole automatic repeat ie the that the number of needles in use on the ribber must be even. On the Passaps there are no such rules on the back bed.
With no arrow keys selected the same action is repeated until the lock setting is changed, so in the above, the change is made by manually setting the back lock to N for 2 rows, then back to AX for tuck on both Passap models.
The front bed in the Duo also has a fixed pattern selection, requiring the lock change to N there as well. The E6 built-in pattern selects the all-knit rows, so its lock remains in the KX setting.
The initial pusher setup is manual on both models but not location-dependent in this particular design.
The E 6 console will select the proper pattern based on the pushers in the work position. A look at pusher positions from the E6 manual. Each machine brand has its own specific vocabulary for parts and techniques. Things get a little more complicated on Brother, it is helpful to have an understanding of stitch formation on both beds before tackling more complex knits.
In Brother the needle placement on the main bed matters as it does in tuck lace, so it needs to be verified before any knitting. “Air knitting” is one easy way to do that. Rows 5 or 6 would provide the necessary preselection.
In any punchcard model or Japanese electronic machine, the knitter is usually in charge of keeping track of racking. The E6 provides console prompts for racking positions in this design, facilitating the process.
An attempt to visualize what actions need to happen on the Brother models: the needle setup will match the Duo or the rotated E6 version Considering the required patterning for each bed, empty columns in my charts represent needles that need to be pushed back to A and left out of work on both beds. Textured ladder spaces will not be formed on either bed as is seen when using similar repeats on the single bed. Adding the ribber position and configuration  The top bed can be programmed, this 24-stitch version is suitable for use in punchcard machines. The main bed will knit all needles programmed with punched holes or black pixels and will tuck unpunched squares or white pixels.
The ribber requires setting changes after the initial four and after the last 2 rows of each 6-row repeat.
In addition, there are racking changes after each repeating segment.
In this setup, there will be a knit stitch beside each tuck one up to the all knit rows, helping to anchor the tuck loops. Ribber carriage settings are noted.  Anytime there are needles out of work, cancel the end needle selection. Depending on the machine model being used the repeat may need to be mirrored horizontally to match my in-process photos, true in my 930.
Using design row 5 or 6, air knit a row to find needles that need to be in work on the knit bed. Push non-selected needles out of work, and back to the A position. After doing so, reset the pattern to design row one.
The setting for the racking indicator does not specifically matter. It is often best to consider this before casting on. Here racking is only by one position, avoid 1 or 10. Starting at 5 centers stitches in relationship to each other stitches. As knitting progresses, where the ribber needle positions become obvious and less reliant on checking numbers. Cast on bringing appropriate needles into work on the ribber.
The original needle setup.  Use any favorite cast-on method.
Starting side does not matter unless one is planning on using a color changer, in which case the first preselection row needs to happen from right to left.
Since needles will be manually pushed up to the hold position, make certain that the ribber carriage is not set to hold. In a test swatch, knit several all-knit rows before beginning the pattern. If planning a piece, start with waste yarn and ravel cord prior to casting on with “garment” yarn.
A tool that aids in selecting every third needle is extremely helpful The initial carriage setups used for rows 1-4 The placement of the first needle on the ribber with respect to that of the first on the main bed The first needle in each pair of rows on the ribber needs to be brought up to the E position in every row for the first 4 rows of the 6-row repeat, I began with the first ribber needle on the left. The needles brought up to E will knit, and help anchor down the knit bed tuck stitch on their left, and the needles on their right will tuck. In turn, the main bed selected needles will anchor loops formed on the ribber, the nonselected will tuck.
The appearance after the tuck loops have all been formed and the needles holding them up to that point are preselected forward just prior to the 2 all knit rows. The knit carriage is left on tuck in both directions, while the ribber is set to knit for 2 rows. It is not necessary to change the P lever to R, with the other buttons set to N, knit is king.  Time to rack so that the first needle on the ribber will now be to the left of the first on the main bed. Push down lightly on the first 2 ribber needles on the left before racking in case those first stitches are a bit snug, to avoid starting needles crashing into each other as you move needle positions.  Knit 2 rows.
Rack again to the initial position,  change ribber settings again, and repeat the process as described. The proof of concept: the error shows what happens when one misses changing the ribber settings back to tuck.  If that is not challenging enough, add a color change, knitting the first 4 rows using color one, and the 2 all-knit rows with color 2.  I used to tell my students to develop a sort of tune that could be sung (mentally) as a reminder of the steps in complex fabrics ie bring up 1, 2, 3, 4, rack, change color, change settings, knit 2, rack, change color, change settings, bring up, etc. but my advice if you really want to knit this fabric in a full piece is to borrow and E6 or pay someone else to knit it for you 😉

Ribber trims 4

Ribber trims 2  presented a series of ideas for edgings I meant to return to. Rather than adding more to that post presently, I am expanding on the topic here.
Scalloped trims are popular in single-bed knits. Preventing any needles from knitting for any number of rows will form a wave. If automatic needle selection is used, they may be formed using both the tuck and slip stitch settings.
This version from the Brother Ribber Techniques, with knitting directions included in Ribber trims and edgings 1 If there is a problem in double bed versions using loops formed by holding stitches or tuck patterning, try completing a tubular cast-on before starting either sequence.
Using tuck stitch rows created manually way can work as a cast-on method:
Begin with a familiar yarn and tensions to form the usual zig-zag row from right to left
Set the ribber to slip in both directions
Bring every 6th needle on the top bed out to hold, and set the knit carriage to knit. At that point the yarn will be knitting solely on the top bed, so tension needs to be adjusted closer to what may be normally used in knitting it in stocking stitch.
Set the ribber to slip in both directions. 
Make at least 4 passes on the main bed, 6 will yield more of an effect but may be hard to manage on Japanese machines while in Passap, the strippers facilitate the process.
My first swatches were knit using 2/8 wool, which pushes the limits for smooth knitting in every needle rib on the 4.5mm machine. After knitting 5 rows the top bed stitches began riding up.  The next row needs to be knit across both beds, sealing the scallop.
Bringing the top bed needles all the way forward can help with that, but to ensure gathered loops will knit off properly, a bit of fiddling may be required, any tool can be used to push down lightly on alternating sides of the loops to keep the stitches to their side from unraveling. Release the hold lever on the top bed, set the ribber to knit in both directions, and continue in every needle rib to the desired length
The top images show the result of forgetting to set the ribber to knit, so there are 2 extra all-knit rows on the top bed, the bottom images were knit with the proper setting transition Since the top bed only knits for several rows, the ribber stitches can be seen elongated on this side of the knit Switching to a 2/20 wool, the same needle spacing, and holding stitches for 6 rows: One last fiber switch, a different 2/20 wool shade.
Here the detail is used at the bottom of the stocking stitch swatch rather than a ribbed one.
Watch for loops hung up on gatepegs, seen below in the top swatch.
The scallop shape wanted to turn toward the knit side but did set with some steaming.
Upon completing the holding sequence, transfer all ribber stitches to the top bed.
The tension in the swatch remained the same throughout, but in the bottom views, a loose joining row (perhaps too loose) was knit after transferring all ribber stitches to the top bed, as is often done for smoother transitions in single-bed hems. After the single loosely knit row, the tension is adjusted set to a number appropriate for the specific yarn in single-bed work.  This information and pngs expand on the knit charts in the 2019 post. If the pngs are copied, check that mode has not been altered to RGB automatically, and index back to BW mode prior to downloading them to machines for knitting.
Though, in general, starting side does not often matter, when testing techniques consistently beginning on the same side and leaving a yarn end will help identify which surface is knit facing or purl facing and whether that is of implications in the specific design.
Designing the repeat tiled for the width of the bed when working on electronic machines allows one the opportunity to add all knit borders in specific widths and to program the result as single motifs without concerns about needle placements on the knit bed or how to influence edges.
Punchcard knitters are faced with fixed 24-stitch locations on the needle bed, all knit borders would require manually bringing the needles involved out to E before each carriage pass.
As always, white pixels/unpunched areas tuck, and black pixels/ punched holes knit.
These repeats can make for interesting all-over fabrics as well as serve for edgings that flair and form bottoms that are wavy to different degrees.
12X18Knit using a superfine 2/18 merino: the tension on either or both beds may need to be adjusted repeatedly for stitches to form and knit off properly, reflected in stitch size variations here.  What happens when one is so engrossed with watching stitch formation that the fact that the cone has just run out of yarn is completely missed 12X24 Switching yarn to 2/18 silk wool at the same tension produces knit with a very different density and drape. Light bounces off this yarn interestingly, making it harder to photograph in sharper focus.  Here the same brand and weight yarn, steamed and pressed lightly, resulting in some flattening of the tuck texture’s 3D effect. Different colors or even different dye-lots of the same color in any yarn can behave differently with all else being equal.  The relaxed and stretched view and an attempt at showing its ruffling effect.  A very interesting surprise: a few years ago during one of my temporary obsessions I developed racked scale-like 3D patterns, this series reflects some of my first attempts One of several illustrated repeats designed for assistance from needle patterning preselections  I wondered whether the triangular repeat for the trim above modified to a diamond shape might produce similar results.

Pintucks 2, ripples in knits using the ribber

This content, on a topic I intended to expand on further, had been “tucked” away as a draft last March.
Ripples in knits are created by knitting an unbalanced fabric, with one of the beds knitting more rows than the opposite bed.
Depending on the design, the fabrics may share similarities with blistered stitches DBJ.
Pintucks vs shadow pleats introduces fair isle patterning possibilities on the top bed.
Pintucks are created by knitting on one bed and slipping on the other for often as many as 6-10 rows followed by plain knitting on both beds to seal the fabric together.
Nopps are made in a similar fashion, but using the tuck setting and for fewer rows. Before moving on to exploring added textures, this shares a few of the many options.
Both fabrics may be knit with or without added automatic patterning.
Pintucks tend to be firmer and with less stretch than fabrics using tuck settings.
Some published sources for single-color versions, though intersections could be isolated and horizontal colored stripes continuing on both beds may be introduced:
fromStudio punchcard volumes included samples, calling the fabric punch pin tuck

Brother introduced the idea in their Ribber Techniques Book: My experience in knitting these fabrics has been using Brother and Passap. In my blog posts, I discuss fabrics and settings I am able to test and reproduce, so specific ones for other machine brands are not usually included for specific techniques.
In creating DIY textures, an extra needle is generally used on the bed used to knit the sealing rows.
Nonautomated patterning may be created by leaving needles out of work on either bed. Adding racking changes the fabric even further.
If automatic patterning is used along with tuck or slip settings, the end needle selection on the patterning bed is canceled or the needles on either side of the ones out of work will knit the stitches rather than tucking or slipping them.
Many decisions are made in the process, beginning with a simple variation, A, followed by B with a small number of needles out of work on the top bed,
which will create ladders between knit spaces as would happen in any single-bed knitting.
Switching to needles out of work on the ribber renders the main bed knitting with blocks of pattern and no floats, C.
The remaining pintucks are created with 6 rows of knitting on the top bed. C: racking sequence is by one position in either direction, followed by another pintuck with no racking before every sealing row
D: racking is by one position in each direction, before every sealing row
E: racking by one position X4 before each sealing row, then reversing the sequence in the opposite direction. The effect on the knit side is subtle. Additional swatch photos in each post
Ribber fabrics produced with 2 knit carriages selecting needles 
racking   Adding lots of texture:  Combining knit carriage needle selection with racking and needles out of work. The surface here is more dramatic, it is best to use yarns with memory such as wool, and to have a memo provided by the machine if possible or some other way to help track the racking sequence without errors in long projects.   Racking by more positions as well as more knit rows on the top bed. Racking: Passap/Brother 3 Combining  knit carriage needle selection with rackingAdding complexity with transfers from one bed to the other to racking A Passap special begins with deciding on which bed to produce patterning, at first with manual selection on the back bed, then with a programmed repeat on the front bed, no racking At the top of the swatch, to secure stitches, a strip of woven interfacing was ironed on, and a zig-zag stitch was added with a sewing machine before further trimming.

More on standard and modified 1X1 and 2X2 ribs

Ribber manuals usually give instructions and diagrams for ribs, and in some early manuals, the way in which the needles should be set up so that side edges will match the when garment bands are seamed is not included.
In later model manuals, instructions began to call “perfect selvages”.
The position of the beds in relation to each other is dependent on the pitch lever. When both beds are being used, both the pitch and racking levers may be moved so that the ribber can travel one or half turns in either direction. A half turn is sometimes used to set up the position for some accessories, or may simply be what works best in the specific knit fabric and yarn.
If traveling between Japanese brand instructions, some of the names for parts differ.
Brother Studio or Silver Reed:
A: half pitch lever, B: swing handle, C: swing indicator Not leaving out the Passap: the racking handle and racking indicator The Passap racking handle moves in a circular direction, clockwise or counterclockwise.
On the Bulky machines, after the zig-zag row, consider ladderback arrangements for less thick and stiff double bed work.
If the bulky rib was to be applied to single-bed work, I was never happy with direct transitions on the machine. Hand-knitters have some advantages when owning a range of needle sizes and types. One option then is to start on waste yarn, end with a row of ravel-cord, and begin the piece on open stitches. Upon its completion, pick up the open stitches on an appropriate size knitting needle, and knit and bind off the rib by hand.
If only the look of the cast-on row is not pleasing, another option can be to start ribbing after waste yarn configured to the necessary needle arrangement, ending with a row of ravel-cord and beginning the rib on open stitches while leaving a length of yarn for binding it off later.
After completing the piece, pick up the open stitches with a small gauge double-point knitting needle for added ease, but use an appropriate size hand knitting needle for binding off in rib configuration.
When choosing to leave a length of yarn for binding off a previously knit piece of fabric, wrap around all needles in work a minimum of four times, wrap it in a small bundle and secure it with yarn or another small tie, or wrap it around a bobbin like those used in embroidery or intarsia.
The third circular row is not needed after the zig-zag row and placement and addition of weights in ribber cast-ons. It actually will form a small float on one side of the fabric that will show if that side becomes the knit face of the finished piece.
That third row is recommended here, as in most pubs, in Brother Ribber Techniques.
The first setup given does not include any transfers between beds The rib with transfers recommendation results in a commercial-type rib which is used when the garment is to be knit entirely on double beds or when using fine yarns so that stitches are brought closer together, resulting in less distortion. Its use can make ribbed bands appear narrower than the remaining part of the garment, with no buckling or distortions after the technique change, while allowing the needed stretch.
There are other arrangements that will form ribs that lie flat and make better joins when used ie as bands in cardigan fronts.
Test swatches should include transfers to the final fabric bed arrangement, whether single or double followed by treating the swatch as one would the final piece before calculating the gauge and committing to a garment or even an accessory.
Begin with a zig-zag row and tension suitable for the yarn being used, and knit 2 circular rows.
At this point, stitches are transferred. If the fabric is to be used with the purl side facing transfer stitches on the ribber, for the knit side facing make the transfer on the main bed.
In this post, it is assumed that the knit side will be worn on the outside in each case. Seaming edge stitch allowances are taken into account.
The tension used after any final transfers to the opposite bed will need adjustment based on the yarn thickness, twist, and machine being used. It is wise to begin any experiments with familiar yarns.
The racking lever position is recommended to be set to 5 prior to any cast-on. Other positions may be used as long as the ribber can still be moved by one to one-and-a-half positions to either the right or left if there is any reason to do so. Passap markings are different. When racking I found it easier to mark its bed with my own numbers since I usually work out most of my patterns on Japanese machines. They do not apply if any reader technique racking numbers are in use, since any console prompts are based on the manufacturer’s sequencing. A practical reminder from Silver Reed: do not turn the swing/racking handle on any Japanese machine with all needles up to D on both beds on a serious collision course.   It can sometimes appear easier when making transfers to have needles point to point. If that or another bed adjustment is made to any personal preference, keep the desired final setup in mind, and before continuing to knit, check that the machine is set for half pitch.
Prior to casting on bring the main bed needles into work. Bring the same number of needles into work on the ribber, plus an extra needle on the right.
On Half pitch, H, for knit side facing, transfer stitches from the main bed to the ribber for a 1X1 effect. The number of needles in work on the main bed should be a multiple of 2+1. After the transfer, adjust the tension settings. The pitch remains on H For a 2X2 effect, the cast-on method is the same, with every 3rd stitch transferred down to the ribber.  The number of needles on the main bed should be a multiple of 3+2 When the band is complete, all stitches may be transferred up to the top bed and the piece continues in single-bed knitting.
Straightforward two-by-two bands knit and applied as a long vertical strip will want to curl when joined to a knit. Modified commercial rib variations will produce far better results.
If a sideways application is chosen, after all the stitches are transferred to the top bed, knit a row before applying the band by the chosen method. This row may appear as a stitching line on the finished piece.
Other variations: here the number of needles in work on the top bed must be a multiple of 4 +1
with half pitch on H bring needles into work on both beds A single needle on each bed seen here on the left, remains in place until the cast on is complete the ribber is racked to the left, half pitch now set to P, those 2 end needles on the left of the above chart are moved to make the edges of the work identical With a multiple of 3+1 needles in work on the main bed, begin with every needle, on half pitch the ribber is moved 1 whole position with the racking lever to the left, the end stitches on the above left are moved so as to produce identical ends.  The post Seaming, joining, picking up stitches 3, ribbed knits offers suggestions on seaming techniques.
Vertically worked bands require their own small gauge swatch. The weighing of a  small strip is bound to differ from that distributed across a wider band ie that at the waistline, and the results need to be calculated accordingly. The same consideration is a factor in shaped sleeves vs. sweater bodies.
End the bands with waste yarn, then if too many rows have been knit they can be unraveled, or if more are required the stitches may be rehung on the machine for continued knitting.
Apply bands to garment pieces that have been allowed to rest.
Some binding-off methods have been discussed in the post on binding off on the double bed.
Binding off ribbing sparks discussions on which way is best, especially if both the cast-on and bound-off edges are both visible and the hunt is on to get them both to match.
To review, bind-offs may be done in a multitude of ways on the machine by transferring stitches between beds or leaving them where they are, as well as working them after removing the knit from the machine on waste yarn.
Instructions abound in hand-knitting pubs and machine-knitting demonstrators talk about smiles-and-frowns visualizations including in some youtube videos when discussing tapestry needle-sewn bind-offs.
There are techniques that can accomplish similar effects with the knitting still on the machine as long as there is room to jump up several tension numbers before knitting the last row with both carriages from right to left.
The drawback I find using a tapestry needle with the work when it is off the machine is managing the length of yarn necessary in pieces wider than demonstration swatches.
The process may be easier for some if the work is taken off the machine and onto a hand-knitting needle, preferably a double-pointed one with needle stoppers available. Any hand-knitting illustrations or videos then become easier to follow.
With a tapestry needle, one inserts the needle as if to purl into the first (knit, cyan) stitch and as if to knit on the second (purl, yellow), both stitches are left on the needle.
The first stitch is then “knit off” and the needle is inserted into the next stitch (knit) as if to purl. Both stitches are left on the needle. Repeat steps 1 and 2. I used to suggest my students think up ditties for repeated actions, here it might be “purl into a knit and knit into a purl”.  The steps after the work is scrapped off on waste yarn bring up discussions on how best to scrap off.
The missing how-to preparation for binding off:  When the rib is completed, transfer the stitches on the ribber up to the main bed, pulling needles out to E as you move across the bed
Cut the yarn, leaving an end long enough for binding off.
Remove the ribber arm, exchange it for the standard sinker plate, place a contrasting color yarn in feeder A and secure it.
My test piece ended COR. Push in the cam button for slip stitch corresponding to the direction in which the carriage will move on its next pass, in this case, the left one. Another option is to simply push in both.
As the carriage moves to the opposite side, what is now identified as knit stitches will knit, and the B position needles will be skipped, creating a float. Knit at least 10 rows in the contrast yarn. No ravel cord is needed as knitting ravels down easily to be removed. When the piece is scrapped off, the all knit rows will roll nicely to the back of the swatch, and the rib can be stretched easily, with the top of the knit and purl stitches easily identified for sewing. Two by 2 ribs with stitches transferred to a hand-knitting needle: Using the same waste yarn scrap off keeping as for the one-by-one rib, but keeping the two-by-two needle arrangements when setting the knit carriage cam buttons to slip:

If the stitches are small, it is possible to weave under bars 2 at a time, always test on swatches before committing any technique to a garment.
In A there is a fully formed knit stitch on each edge while in B, some shaping may be seen. The gauge for the ribbed fabric vs stocking or other techniques may be quite different, so in joining, it may be necessary to adjust sequences of pick-ups on either side in order to ease any differences in fabric lengths and maintain a smooth, flat join.

Working with diagonal patterning in machine knitting

After a slow down in my blog posts for a variety of reasons I find myself playing catch up with the eternal list of knit fabrics that I wish to explore out of my own curiosity and the attempt to answer questions from knitters who contacted me directly via the blog or have asked them in the online forums in which I am a member.
Stephen West is a prolific designer of colorful hand knits in a variety of techniques and complexity. This honey-striped scarf is an example.   Slip-stitch patterning is a likely way of knitting a similar effect combined with
the use of the concept familiar to many when making bias cast-on rags.
A fixed number of stitches is cast on and positioned as far to one side of the machine as possible. They are then decreased on a fixed side and increased on the opposite one.
The strip moves across the needle bed, when far enough on the side opposite to the starting one, it is returned to the original needle bed position and the process is repeated until the desired length is reached.
If the moves to and from are performed on solid color rows matching needle selections may not be an issue. If the repeats in other cam settings are to match, then proper needle placement can be assisted by marking the metal bed, the factory-supplied needle tape, or a custom-printed one, and hand-selection for the first design row may be required and planned.
This chart attempts to visualize the proposed movement using colored stripes. Stitches are bound off on one side and cast-on on the other to maintain a fixed width with shaped edges.  If the goal is to maintain straight bias edges, the design repeat would need to be rendered wider in order to compensate for the shifts on the needle bed in turn modifying increases and decreases at a different rate The black cells represent the adjusted stitch counts needed for each pattern band.  When an item such as a scarf is worn, both options will appear as diagonals. If any picture knitting is included and the direction of it matters when the piece is worn, appreciated particularly in representational fair isle, such accessories are best knit as 2 pieces knit from the bottom up, and grafted together at their center after the fact.
Increases and decreases are calculated based on the knit gauge carefully for garments. The approach to accessories may be more casual.
Stripes heights are varied to accommodate any specific design motifs or cam settings and in turn, are added to the base visualization charts.
Here an attempt at 45-degree striping is made by beginning on a 3-stitch tab.  Increasing on the carriage side creates loops, while those opposite the carriage form knots.
Increases and decreases are indicated by arrows.
Increases are made on alternating sides, opposite the carriage, to produce matching edges.
The red cells in the chart represent the carriage side prior to each pass.
Table cells have been rendered rectangular in a 4 to 3 ratio, estimating the difference in gauge between stitches and rows.
Striping for an even number of rows matters if color changes are made on a fixed side ie if a color changer is in use. Yarn ends at color changes may be cut or the yarn can be carried up the side depending on preference and the number of rows involved. If carried up for long stretches, the alternate color yarn not in use may be secured by e wrapping it on the end needle periodically. Care needs to be taken that the float up the side is not so short as to have an effect on the swatch length and having an effort to remedy that will leave yarn ends too short to be secured.
The result is not going to produce a proper square, garter stitch is the only knit stitch that results in approximately true square shapes.
If the center of the machine is always used for swatches, keep an eye on the stitch formation. If loops are formed repeatedly on specific needles akin to tuck stitches or problem areas such as those in the center of this swatch are encountered, they can be caused by damaged needles or sticky latches that may result from frequent use. Diagonal lines in knits that maintain straight sides are also achieved using short row/holding intarsia techniques. Segments are planned in specific orders which can be varied to form added shapes.  Chevrons would be more easily created by knitting separate strips and seaming as you knit or after the fact. The addition of small-repeat fair isle patterns is also possible. Keep in mind when bringing needles back into work to reverse shaping, needle preselection for accurate patterning in Brother machines needs to be maintained by hand selection.  Some of the published punchcard patterns can serve as a source for diagonal lines that may be tiled and programmed for the full design in addition to being used for their original intent. Numbers 52, 384, and 328 (published with error), are suitable for tuck, slip, and FI with moderately wide floats, while 335 would fail as a tuck stitch.
Tiling as in any patterning will reveal errors, such as here for 328.  The latter was edited to a 22-stitch wide repeat, becoming suitable for only electronic machine models.
The charts with the red grid on the top row were rendered as tables in Numbers. Since their end use is different, they are the color-reversed version of the cards, whose screengrabs were in turn processed in Gimp to create knittable pngs.
The smallest repeats suitable for electronics are given in the center row of images, the amended 328 cannot be reduced in size. The last row illustrates tiling for all files as BW images that may be opened and amended to suit the size of the pieces planned.
Files in png formats for the group: if pngs generated by me in BW indexed mode are downloaded and opened in editors such as Gimp, they will open in RGB mode. To make them suitable for download programs, convert them to indexed BW mode again and save the result. There should be no loss of data.

The repeat is 24X48 The previews may be used to replace color selections with those matching yarn colors used in the project to develop some idea as to how color shifts might affect the final piece.
EON diagonal patterning surrounding blocks containing other shapes may be maintained with slight variations in the size of the shapes used to fill those blocks  References published for weaving can be a source of charts usable for this type of design.
The repeats are given in terms of width (shafts) and height (picks). For proper alignments, the provided charts need to be reproduced in full, or in DIY adaptations careful editing with erasures or additions can still maintain the proper tiling.

Chevrons can be developed from partial repeats. This is from Toyota 950#12, 24X20 drawn in repeat to 144X140  Whether in use for a punchcard model or an electronic one, the convention if the end goal is a tuck stitch fabric, is to color reverse the design  Taking diagonal patterning to the double bed for creating pintuck effects using the slip-stitch setting, this 24X48 repeat explores some of the potential spacings and the resulting ridges.  The next 2 repeats tested, both 24 stitches X 48 rows:  The red line is a reminder that the slipped stitches are being held for as many as 8 rows. It is best to use thin yarn that does not break easily and to watch for the knit stitches riding up.
Slipping in one direction produces a very subtle texture,  while the color-reversed design produces even-sized identifiable folds Adding lettering or small shapes and maintaining the diagonal can result in distortion of the motifs.
One option to add such motifs is to form the knit by beginning on 3 stitches as in this shared swatch and planning the stripes to heights and widths that accommodate adding designs or fonts. Short-row intarsia will also produce diagonal striping, from simple to complex as seen in this chart, with knitting sequence numbered for each segment.  complex_number_01A limited number of rows may be knit in stocking stitch in areas following shapes not simply to travel to the opposite side and reverse shaping,  but also to add small rolls or hems.
Another use might be to add small vertical motif details or patterning in their usual orientation.
The limit appears to be a maximum of 8 rows of alternative patterns, in order to keep the short-rowed areas from developing into distorted edges, which may be variable depending on the yarn and pattern used.
This first swatch was knit using progressively thinner yarns, wool, wool rayon, and a 2/24 acrylic in the FI segment. FI is a slip stitch that narrows the knit. The dark acrylic color stitch definition here gets lost. The band is seen pulling in the short-row segments on both sides. The shaping in both the top and bottom segments is by 2 stitches at a time.  The result in different yarns of equal thickness, with the FI band knit at a tension one full number looser than the stocking stitch areas, with the top and bottom solid color segments now shaped 3 stitches at a time. There is a trick when making A-line skirts to change the triangles that would poke out normally at the bottom if shaping were to begin immediately used as a design feature in many runway knits recently. If between an inch or 2 are actually knit up straight before shaping starts, the problem is eliminated. Depending on the design this may be a solution or it may read as a patterning error.
There are some conventions and “rules” for short-row techniques, but they do not always apply.
Keeping good notes helps to make successful experiments reproducible.
Two more tries began to experiment with working on the first and last groups in the holding techniques on a different number of stitches than the remaining shapes, noting differences. In the first an all-knit row is made across the short-row eyelets, reducing the planned FI band from 6 rows to 5. A rough spot in maintaining even stitches on one side is noticeable.  Progress: holding happened at the start of the bottom wedge, the FI was knit at 2 tension numbers looser than the stocking stitch, for 6 rows.  The goal in the short row shaping for the triangles is to maintain vertical edges that appear as straight as possible to the eye. One need not work on large swatches, small ones can provide clues as to differences resulting from variations in the starting side of the short-row shapings.  Studying the results can lead to many variations. There are student theses and careers based on exploring limited techniques to the max.
Building a theoretical true square or other predictable shapes is subject to the yarn and tension used. Beginning with a small sample, this shows the order of knitting 2 triangular shapes with the carriage beginning to knit each shape from alternate sides. In this case, 2 stitches are to be brought in and out of holding at a time. Because each color knits for 2 rows, small slits happen in the fabric resulting in eyelets. They may be used as design features, or attempts can be made to reduce their size. One way to do so is to have plain knit rows between holding selections to keep the small slits from intersecting and becoming double height. On the left swatch, one yellow row was knit to the left before reverse shaping in the same color. In the swatch on the right, in addition, 2 rows were knit in the blue prior to reverse shaping.  Reviewing the concept and developing a chart for larger swatches: the cyan color cells represent stitches in the hold position and the white cells stitches that will be knit.
At the top of the first wedge, most needles will be in the hold position, return them all to the B position manually before knitting the next row.
With the carriage on either side, set it for KCI with the cam buttons to slip for a free pass to the opposite side, the first FI pattern row will pre-select. Holding need not be canceled, since no needles are brought far enough out for the technique.
Cancel the slip setting, change the cam setting for FI knitting, place the pairs of colors in their corresponding feeders, and knit 6-8 rows of pattern.
Bring all needles out to hold except for the first desired group, if the holding lever has been canceled, reset it and commence reverse shaping.  Merrily knitting along and you forget to loosen the tension for the fair isle stripe: And what if the FI were to actually follow diagonal colored stripes? The approach is the same. I am right-handed, my default is often to begin on the right. Left-handed knitters can mirror charts as needed to make them easier to follow.
The first triangle is shaped from right toward left, subsequent ones begin on the left, then to wrap or not wrap becomes the question. Review of wrapping, which does not disturb the stitch on or the position of the wrapped needle:   bothI obstinately use random yarns at hand, sometimes too thin for the task at hand, true here. Any type of intarsia, of which holding is one, will be accompanied by lots of yarn ends that will require weaving in. Some of the stitches were wrapped here, some not, and maybe the eyelets could be considered a pleasing design feature. The 8 rows of FI, knit at 2 full tension numbers higher than that used for stocking stitch, minimizes the size of the eyelets all on their own on both sides of its stripe. Errors in bringing an added group or not into work may not always be immediately visible, frogging this type of knitting can be painful.
I would not use the last 6 stitch modification in any future swatches. Elizabeth Zimmermann published many patterns for hand knitting utilizing garter stitch and striped diagonal wedges for garment shaping.
Multiple colors per row patterning may be maintained by beginning planning with diagonal straight lines, seen here in a 32X32 repeat.  Opened in img2track The design will be elongated, and 256 passes are required to finish a single repeat Each color may be edited to suit. Quick visualizations of a few of the possible repeat arrangements using the file as is Avoiding lots of extra knit rows by eliminating one of the colors.  The larger designs may need to be knit in sections depending on the available memory in the knitting machine model being used.

Machine-knit stitches do not form as close to square ones found in garter stitches. Rendering the full-scale garment on a knit leader would make knitting to gauge while avoiding tons of math calculations possible.
DIY is a bit like assembling paper cut-outs that are required to fit together, first attempts at planning do not always succeed. One may begin at different parts of the piece and seam two halves together if necessary in order to keep matching stitch formations in both directions. Stripes may be added to form secondary intersecting shapes. On the left is a simple one-piece vest concept with no miters in the back panel, which may be knit from the bottom up or as two pieces with a center seam.
The bolero style is repeated in 2 separate pieces with mirror shaping in the second and would be joined at the center back.
The knit gauge is easier to maintain in short or small wearables.   Many garments may be made following the concepts for creating “pies”.
Decades ago batwing sweaters based on a sideways circular knit concept were standard presentations at knit seminars. Short-row diagonal graduated wedges were followed by varying amounts of all knit rows.
This idea for a short sleeve garment is from a Japanese magazine. In creating such illustrations because of the scale of the publication, the aspect ratio is distorted. In the final garment, the bottom circumference can in fact be far narrower than it might appear to the eye in the sketch and may be gathered or left released depending on design goals. The neckline diameter at the end of the project, after joining one shoulder, is gathered with evenly distributed decreases to the desired measurement prior to knitting the collar.  A way to form a long sleeve item, using binding off and casting on stitches in addition to shaped wedges followed by all knit rows. Knitting a garment on the bias at 45 degrees will produce a knit fabric that drapes differently.
Horizontal patterning can turn into diagonals and chevrons, and fancy decreases may be used in the center shaping of the garment.
Pre-computer programs and knitleaders, an easy way to sort out shaping for garments, was to begin by drawing on large sheets of graph paper. An all-square grid is fine.
Calculate a 10 cm/4 inch knitting gauge to the second decimal point before any rounding off. For example, if the gauge works out to be 5.728, and the measurement needed is 19.5 inches, the multiplied value result is 111.696, which can be rounded off to a 112-row line on the graph paper.
Working in cm can actually lead to easier calculations and is required when using a charting device.
Each cell in the graph paper grid equals one stitch and one row.
For knitting on the straight grain, based on gauge, draw series dots placing them on the beginning and the ending pots for each measurement, and connect them with straight lines.
Curves such as those necessary for necklines may be composed of short straight-line segments.
When knitting from the bottom up, continue with a colored pencil, filling in squares as they jog in or out, maintaining the new outline as close to the first as possible.
For the bias knit, whether on graph paper, the computer, or a charting device, begin by drawing a 45-degree line.
Rotate and trace the unmodified original straight-line image in place, follow the lines, and mark in and out jogs once more in color for contrast.
This is a very small chart so outline jogs in far larger pieces cannot be reflected. They would produce edges not as straight as in standard knitting, which will need to be considered when joining finished pieces.
As the piece is rotated, a wider grid base is required. Consider that the motif images as they are worked on the purl side will be mirrored horizontally on the knit side, a particular consideration if any text is introduced. Comparing theoretical purl as opposed to knit views on the left, two purl views on the right.   Fonts in various stitch and row counts are useful when planning knit text.
The point at which the text or pattern is introduced needs to have enough stitches in work on the machine to contain the intended words, ie for the above, a minimum ground, independent of shaping, would need to contain more than 9 rows if solid color stripes are to be added above and below it, and 26 stitches in width in this case.
A proof of concept swatch with arbitrary shaping on every other row illustrates the need for shaping based on a calculated gauge if a square is indeed the aim.
I knit on a 930 where mirroring is automated for programmed designs, so the text was programmed as drawn.
Sometimes less information is more. It became evident very soon that the placement of the text on the left was wrong if the aim was to have it centered in the final shape, and that more rows were needed at the top of the design.
On the right, the purl side as it faces the knitter is shown, with black pixels used to represent increases and decreases. The center red line separates the needle placements on either side of 0, and the text is shown in the default mirroring. The respective swatches after their rotation preview one of the potential results A true diagonal repeat may be planned for motif patterning knit from the bottom up. The drawback is that for executing a fair isle using more than 2 colors or with multiple color changes, partially illustrated on the far right, the 32X32 repeat would need to be rotated and knit as above.  

From the Brother machine knitting techniques book, a suggestion for dividing a sweater front into diagonal halves created by using the holding technique  

The idea of chaining the eyelet areas to reduce the size of the slits is an interesting one that up to now I have not tested.

Diagonal pleats

Long vertical button holes/ slits in knit fabric 1: intarsia

There has been a long thread in the machine knitting FB page lately that arose from a share of these 2 images.  There are three hand-manipulated methods available on most machines. True intarsia knits all parts of a design simultaneously and is best suited for complicated designs. Short-rowing is best suited to diagonal shapes, while the slip method is to vertical shapes. Both knit designs one section at a time and have no floats between shapes on the purl side.
True intarsia is also called bobbin or tapestry knitting.
Members contributed their concepts along with some of their swatches illustrating the idea that effects similar to the cables on the left could be executed in intarsia.
One member shared an Instagram link with a body of work by cari + carl using the technique.
I have been knitting for decades. Intarsia on the knitting machine along with cables or most hand-technique-only finished garments is something I have avoided at times, simply because they were too time-consuming when knitting items for sale in shows or even galleries, at others because some evoke my personal flight response.
I used to hand knit as well, preferred lace, intarsia, and most definitely complex cables knit on 2 needles.
Prior to attending a design school as a student, I worked in a shop that happened to sell knitting machines but whose main income came from selling yarn and lessons to hand knitters. As part of my responsibility, I had the job of hand knitting bulky intarsia sweater samples which at the time featured large images, often of birds or other animals, that were sometimes wrapped over the shoulder and onto the back or sleeves.
As I began to work on Brother machines, I acquired all the related accessories. My intarsia carriages other than in demos were stored unused for years. I gave away my yarn-brake years ago,  and very recently shipped my Brother 260 bulky intarsia carriage to a Parsons student, so by default any of my experiments at present will be knit on a standard km.
I was stuck on the idea at first of large stitch count cable crossings being made by using holding techniques and initially could not imagine how the same could be done using an intarsia carriage. It took a while for me to sort out in my brain that slits may be created in intarsia by simply not wrapping stitches as the knitting continues and maintaining color changes across the row of knitting, resuming yarn crossings in the areas that require joining.
Some considerations: using the intarsia carriage, the stitches are formed in stocking stitch, so the resulting knit strips will tend to curl to the purl side, far more noticeable in narrow strips, perhaps less so in yarns that will result in stitches that are permanently set by blocking. Using bulky yarns on appropriate gauge machines may also lessen the curling.
Experimenting with familiar yarns helps determine whether the familiar knit carriage tension when using them on the single-bed matches that achieved when the intarsia carriage is in use.
My Brother Machine Intarsia Standard carriage is the KA-8210 model:   It was intended for use on early Brother punchcard models listed in the manual. Trippers were required to advance the row counter in later models.

The B tripper doesn’t engage in my carriage, the A tripper does, and triggers the row counter in my 930.
The yarn placement for intarsia knitting is the same as that used in knit weaving.
“Sinkers” are provided with the accessory, and frequently turn up in the “identify this please” questions in forums. I have a tendency developed early on to use clothes pins as small weights when needed, used them in the swatch that follows, and if bobbins filled with yarns are used instead of the yarn balls or cones, their weight will be enough to keep yarn lengths manageable.
Each area of color has its own yarn supply, usually wound on bobbins.
Yarn bobbins are available in a variety of materials and sizes from cardboard to plastic or even wood. The overall shape may vary, but the concept of wrapping yarn around the center of a narrowing shape and slipping an end through a slot to secure it is shared by all types related to the image on the left. It is possible to make your own in similar configurations out of any material that will hold its shape.
The clamshell version became my preferred version of the tool. The small ones come in handy for holding ravel cords or even wire.   When knitting more than a swatch it is likely far easier to work without a ribber in place. I like to do all my knitting with the main bed anchored and angled with ribber clamps rather than flat. If the threader is missing from the supply of sinkers, floss threaders can help, and are also handy when beading on the machine. The used yarn here is 2/18 To knit: begin with a familiar yarn. This carriage may actually produce a different stitch size and resulting gauge than the result when using the same tension number on the knit carriage, a factor if the plan is to combine intarsia segments with the main carriage for any stocking stitch across all needles in use.
Brother knitters are familiar with the preselection of needles when patterning. When using the intarsia carriage all the needles in work, B, are aligned in the D position. They are seen below just behind the latches.
Knitting may begin on either side. Start on waste yarn and ravel cord if working on a large piece, cast on, and knit one row unless casting on in different colors matters.
Remove the knit carriage and continue using the intarsia carriage, beginning with it opposite the side on which the knit carriage had been removed, leaving a yarn end.  If any latches are closed, the stitches will drop on the next intarsia carriage pass. They will drop as well if the yarn skips being laid over any of the needles in the D position. There will be an eyelet at the very start of the process which is eliminated when the yarn ends are woven in. A reminder for Studio knitters: Brother needle positions are A, B, D, and E, C was present in very early models but was then eliminated permanently, while Studio kept the alphabet in proper order.
Laying on the yarn  An illustration of the crossings to eliminate holes.  I had initially begun on an uneven number of stitches, then decided it was more practical to be able to use 7 prong tools for my planned cable crossing, so I decreased on each side accordingly.
Eliminating the crossings will deliberately cause separations between the colors.
If the intent is to cross the resulting strips, then the side of each where transfers stop matters.  Using the appropriate tools remove the stitches onto them.    The yarn ends need to be kept free for the next intarsia carriage pass, the needles are aligned in the B position after the cable crossing is created. Remove the carriage by sliding it off the bed or using the release knob Return it to the opposite side to make a free pass and return to the side of the needle bed where the necessary yarn ends will be available to proceed.  Resume wrapping to join the strips once more Knit to the desired length, and bind off in one or more colors.
When off the machine the stocking stitch strips will curl. Here the knit is exposed to steam and some light pressing This gigantic swatch, for me, is the end of my intarsia knitting, though it is best to never say never.

If cable crossings are the goal for this and following slit techniques, planning the crossings in color can help track the process. This is one of my earliest illustrations for doing so, from my Excel days, followed by a series of later blog posts on the topic. screenshot_33

More “buttonholes” and slits

In the past few years, in many runway collections, knit pieces have featured slits that happen either/both horizontally or vertically, with some effects achieved by turning the fabric sideways.
My first post on horizontal slits was written in 2016.
This post will share published references describing additional various methods for creating them.
A review of grafting aka Kitchener stitch is illustrated here for hand knitting and used in some of the buttonholes/slits that follow. Some single-bed buttonholes were illustrated in the post. One of the many resources Horizontal single-bed: using a ravel cord and tapestry needle  A vertical option  Single stitch eyelet in knit one purl one rib, suitable only for small buttons Another version: leave the needle in B position out of work for a few rows, slide latch tool under a couple of the resulting floats, pick up the next in the hook, and latch-up as shown.      Using waste yarn/ ravel cord followed by sewn bind-off, possible on unfolded fabric bands   An interesting translation in the publication of horizontal 😉 

The published reference to waste yarn here implies the use of a contrasting color yarn in a fiber content that allows for it to easily be slipped out when the process indicates. Any smooth yarn that will not break easily and can be knit at the same tension as the knit piece for a comparable gauge may be used, ie crochet cotton or nylon. Although yarns that shed may function for this purpose, they may leave contrasting bits of fiber and color behind in the finished knit that will not be removable.
Double-layer buttonholes may be used in stocking stitch bands applied to the side edge of a garment ie cardigans upon completion of the piece or may be planned in hems if the piece is to be turned sideways.  Here they are folded horizontally on a band that will be applied to the finished edge ie of a cardigan’s front
1: push the required needles to hold, knit them back with waste yarn
2: continue to the position for the next slit, and repeat
3: with a transfer-tool pick up the sinker loops of the first slit that were
created with waste yarn
4: place the sinker loops onto the needles in the holding position
5: push the needles back into the working position
6: knit loops through pre-existing stitches
7: to complete the lower edge of the buttonhole transfer the second
stitch to the first stitch of the buttonhole
8: transfer both stitches onto the empty needle
9-11: repeat the process
12: pick up the loop below the waste yarn
13: place the loops on their respective empty needles
14: continue to knit, and pull out waste yarn after a few rows to check for proper formation of the buttonholes It is possible to work across a whole band, here the joining method uses a tapestry needle and is akin to grafting.   Buttonholes folded vertically are actually worked on live stitches. Pressing the fabric helps to set them. Another view: This method uses holding on the ribber to create vertical openings tappet tool. The latter is the ancient term used for what has come to be known as a latch tool
