Unconventional uses for punchcards 3: lace in rib

The question periodically comes up with regards to the possibility of using the lace carriage when knitting every needle rib fabric. The lace carriage does not operate with the ribber bed in use in the standard up position, there is not enough clearance between the beds for it to travel from one side to the other across the needle bed. It is possible to drop the ribber down one click, opening up the space between the beds, supposedly to allow for the use of thicker yarns.

My machine is old enough for the ribber to be bowed in the center, increasing the space between the beds there. Trying to use that position for every needle rib in my desired yarn I got yarn breakage in the center of the bed, some skipped stitches, and the sides of the needle bed were still up too high for the LC to have a clear passage. The problem appeared to be due to its brushes hitting the gate pegs. With the brushes removed, but with some grinding against those same gate pegs the LC was able to move along the top bed. At least on my machine, I am giving up on the idea of using it, even if only to preselect needles, let alone make transfers.
This page is from the Ribber techniques book. The fact that transfers are broken up with blocks where there are no transfers, including some with stitches transferred to the opposite bed, makes it easier to track transfers than if using all over designs. Standard pronged tools are sufficient to move the single stitches or groups of three. 

It is possible to transfer larger groups of needles on the main bed to create lace patterns, done of necessity in two-color brioche, but here I am seeking to modify lace punchcards so that the fabric based on them may be created successfully with as few errors and dropped stitches as possible.
My first attempt was made using a second knit carriage set to slip in both directions to preselect needles for transfers,  using a small lace repeat to test the idea. The advantage of this method is that the original lace repeat does not need to be altered in any way. The disadvantage, aside from requiring a second carriage to use, is that the width of the piece on the machine is limited.  The ribber carriage is in use and needs to remain at least in part on the machine bed on the far right, limiting the number of needles for possible use on the right side of 0 to about 20. The same work could be done using only one knit carriage as well, but that would require changing the cam buttons from slip in both directions to knit and back to slip at the appropriate points, one of the methods that make it possible to knit lace on the 260 bulky machines

The repeat used is for this swatch is from StitchWorld, and is knit using the second knit carriage for needle preselection.  Because each block contains lace transfers in only one direction, the fabric, even though it is a rib, reflects that in the biasing first in one direction, then in the opposite.

It helps to be clear as to whether one is producing lace repeat for use in a punchcard or an electronic model which in turn will require mirroring, such as when using Ayab or when using slip stitch selection with the knit carriage in combination with lace carriage selections to create shaped lace edgings. Testing on a small swatch will help determine whether mirroring is required for any specific design. Electronic machines usually produce the design as seen on the knit side, punchcard machines as they would be seen on the purl, thus making mirroring a requirement depending on the source for the design.
I usually begin by modifying my chosen repeat in a spreadsheet. On the left, the pairs of blank rows in the original repeat are temporarily colored in grey. It helps to be consistent. One repeat begins with a full motif, the other with half, which can be confusing when first starting out. The plan is to begin by producing a trim or edging, an all-over pattern for significant lengths appears daunting. Dropped stitches in single bed lace are no fun, in rib they may not even be noticed until the knitting is off the machine. The difference between the two repeats: the 2 grey rows on the left are replaced by black pixels or punched holes, with a blank row placed above and below each of the black row pairs. The design is now expanded from a 40-row height to a 50-row one suitable for use in a punchcard machine This explains some of the desired knitting actions Using the method described in other posts, this was the screengrab imported into Gimp. The grey line is a reference point. Cropping the image to content will allow the last blank row to be preserved by having the grey one there. After the crop, it can be bucket filled with white, or when the image is, in turn, bitmapped to B/W, you may find it disappears. Image scale is then used to reduce the repeat for knitting. This is the repeat used to knit the swatch in my 930. If working from it, punchcard knitters need to mirror designs from an electronic source such as this and will find it easier to do so by turning the card over, marking the holes that require punching on that side, doing so, and then inserting the card in the reader in its usual orientation.  The 930 .png: Prior to knitting the pattern using the ribber, it pays to test the repeat single bed to get a sense of where the knit rows occur and to make certain the transfers are happening in the correct direction and in what place on the needle bed. There should be no side by side empty needles, and in this design, the first pairs of transfers result in 3 stitches on one needle in the center of each shape, not side by side holes as seen here in the false start prior to mirroring the image Making things work: both carriages will be operating to and from the left-hand side. The process is facilitated by the use of an extension rail and a color changer. The knit carriage alone will operate to preselect the needles that will need to be hand transferred to create the lace pattern. With the following modification of the repeat, all transfers are made moving away from the knit carriage. So if the KC is on the right, transfer to the left, if it is on the left, transfer to the right. The paired carriages will create the two all-knit rows between lace segments. The blank rows above and below the two all punched or black pixel rows are there to return the carriages to the proper, left side to begin preselection for the next row of transfers. If any end needles are preselected on the knit bed, push them back to B.
It is best to knit 2 rows of full needle rib before beginning transfer, that will ensure that stitches on both beds are formed properly. I did not, had a spot on the cast-on where the loops were not properly placed on the comb, and that is reflected in the area that looks like a stitch was dropped. Begin with a zig-zag row from left to right, knit 2 circular rows, carriages will be on the right. Knit a sealing row to the left, followed by 2 all knit rows, ending with carriages once more on the left side.
COL: remove the yarn from the Knit carriage, hold it in color changer by pushing the adjacent feeder number
separate the 2 carriages
cancel end needle selection
KC is set to slip in both directions, it will remain there for the duration of knitting the pattern, make certain all main bed needles are in the B position
KC operates alone to the right and preselects the first row of transfers
COR transfer preselected needles to the left, away from the carriage. Make certain all needles are in the B position before the next carriage pass. KC will preselect for transfers to the right as it returns to the left side.  Repeat the process until all needles are preselected for an all knit row as you knit back to the left
COL pick up the yarn, engage the ribber carriage knit 2 rows on all needles
Repeat: *COL: remove the yarn from the Knit carriage, separate the 2 carriages, operate KC alone making transfers away from the carriage until all needles are preselected as you knit to the left. 
COL pick up the yarn, engage the ribber carriage knit 2 rows on all needles** until ready to continue in every needle rib.

This method is slow, I found it oddly meditative. It offers an opportunity to review stitch formation, thus avoiding dropped stitches. Hand transferring lace preselection on the single bed as well can sometimes make a fabric achievable that is otherwise cursed by dropped stitches and fiber issues.

Mosaic and maze inspiration from additional sources

Reviewing properties of both: maze patterns have long vertical and horizontal lines broken by regular gaps and the pattern lines change course from the vertical to horizontal, and vice versa. Maze cards can be identified by completely punched row segments, some alternating with every other square marked for two rows, usually geometrically shaped. Areas of stocking stitch produce horizontal colored stripes, and alternating pattern stitches that slip or tuck cause the vertical stripes, which are sometimes pulled nearly diagonal by the influence of tuck or slip. The fabric will be unbalanced because the number of needles slipping or tucking will not be the same on every row. Odd rows usually form 2 color horizontal stripes, even rows vertical stripes, with color changes occurring every 2 rows.
Mosaics have a brick arrangement (tessellae), with clear perimeters and cores, and stepped diagonals (frets) that are partially formed bricks, their positive and negative spaces are created by the use of contrasting colors. The stripe sequence is not as obvious. The punchcard does not resemble the original design.
In single bed work, the reverse of the fabric will show the original design in the texture of its slip or tuck stitches. There usually will be no floats longer than one or two stitches.
The knit side may look like a fair isle but the back lacks any long floats, hence the name “float-less fair isle”
The row gauge is compressed. Tuck fabrics are short and wide, slip ones tend to be short and thin. Some patterns elongate in washing. The tension used is usually one number higher or more than that used for stocking stitch for slip patterns to reduce their narrowing. Tuck knitting may need adjustments to lower tensions. Smooth yarns in contrasting colors are the easiest to establish an easily recognized test pattern, the choices that follow may then be far more personal.

After a while repeat units begin to become familiar. Pondering possibilities: Here the design knit as a fair-isle pattern would produce long floats, going through the steps of converting it for “floatless fair isle” proves of no benefit.

I previously wrote about the use of weaving
drafts as inspiration for other textile techniques, ie. knitting.
Endless published drafts may be found online or in books that might be interpreted for use with mosaic/maze single bed knitting. Having electronic machines available lifts restrictions in pattern width, while repeats too large for narrow items such as scarves may become useful for shawls or blankets. One such repeat,  with .pngs shown for both single and double-height:

This repeat is 36X36 before being lenthened X2 

A different sort of challenge was posed by this 18X18 image with a row shift in areas with a large number of both filled-in or blank squares. As one moves up its magnified version in Gimp it becomes apparent that a row will have a very long float in one of the two colors. One option is to skip that row, resulting in the green gridded repeats for the converted motif both shown both for single and double length. The result in the knitting test swatch produces an unplanned color shift which could be declared to be a design feature, or one can continue with editing the inspiration source. Repeating the separation process with a new graph produces a workable cousin to the original Generally when creating these patterns on Brother machines, patterning selection varies for each pairs of rows. I got distracted while making the above swatch by a phone call, got to the point where there is a very obvious solid black all knit row in the repeat, but “forgot” its presence. I assumed I was having a selection or a carriage issue and scrapped the knitting off. Note to self: “remember to always check the programmed design before you do that again in the future”.

Mosaics, mazes, and DBJ charting meet Numbers, GIMP 2

I shared some working methods to achieve these color separations in 2019/06/29/mosaics-and-maze…numbers-and-gimp/. Mosaics and Mazes came on my radar once more recently, Numbers and Gimp have both been updated, and a few more ideas have occurred to me for managing the necessary color separations. The process as described here assumes that there already is some understanding of Gimp’s and a spreadsheet’s basic functions. These are 2 more samples from Barbara Walker’s book on mosaics, offering the repeats in both a 16 stitch wide and a 24 stitch versions. It is always a good idea after isolating the repeat to tile it in order to get a sense of how multiples line upI was lazy about doing that with the first version of the colored repeat in Numbers and got the result in this swatch  due to a missing black cellThe second try
Beginning with the long method to create the design repeat in the color separation suitable for elongated dbj: the built-in color separation in most Japanese machines for DBJ (179 and color reverse in Passap) will knit each color in each design row only once, as happens on the single bed in knitting fair isle, which in turn is far quicker to knit in that setting than by using slip stitch with color changes every 2 rows. The first preselection row is from the left to the right, the first color knits once before colors are changed every 2 rows.
The dbj color separation that knits in each color for each design row twice begins with preselection from the right and continues with color-changing every 2 rows. The produced image will be twice as long as the original design, not desirable for keeping the aspect ratio as close to the original as possible, but a necessity in creating some alternative types of fabrics.
To start, create a table, making certain that cells are square, equal in size in height, and width. I prefer 20 X20 or more when working with small repeats. The zoom factor can be adjusted, increased for more visibility, and reduced prior to screen grabs that are planned to be further processed in Gimp. At less than 75% while creating charts, adding numbers or text, and sometimes changing the qualities of individual cells is harder to achieve. Large-size images may be scrolled through during the formatting process The working design repeat is 16X16. Create a new table that is 16 cells wide, twice its height, 32.  While holding down the command key, select all the odd-numbered rows planned for the final chart repeat, any errors can be corrected by clicking again on the same spot, still holding the key down. The process may be done in steps, releasing the key in between selecting groups  Choose the hide rows option, hiding 16 rows, Fill in cells the chosen 2 colors Add a column to the table. It will be colored, select the column and choose the no color fill option for it, then resize far wider by clicking and dragging the symbol 
at the upper table right to allow for copying and pasting the full repeat more than once.
Select the chosen repeat in 2 colors, copy and paste it to its right. The rows are re-numbered in the new “chart” thus providing a new set of even/odd-numbered rows. On the new odd-numbered rows, select by holding the command key, choose black squares on each now odd-numbered row, and used no color cell fill option to render them white. Release the key at any point to work on gradually selected groups of cells.  If there is an error, while still holding the command key click on the individual cell or cell group again to erase the action, continue the process. Again, holding the command key selectively, on even-numbered rows add colored cells immediately above any empty cells in the row below.  It could be done all in black, but for me, that becomes difficult to keep accurate when separating large repeats. With some familiarity with spreadsheet creation, this can be fairly quick work. Copy and paste the table content once more. In the new table holding down the command key, on even-numbered rows change colored squares to black resulting in the repeat on the far right. The latter in turn will need to be doubled in height once more prior to knitting the final fabric, whether in the software or by the machine in the downloaded design To produce the .bmp file: copy and paste only the BW portion of the above table once more. Using the cell format option, remove all interior borders,  and if you prefer an outside guide, add an exterior border try zoom at 75% zoom, screengrab the table content, with an added blank border surrounding it, import the result into Gimp. Choose crop to content, that will eliminate the extra white space around the image The final image needs to be double-height, so using the scale option choose image scale to 16 by 64 using the broken chain link prior to entering your numbers. These were my steps in scaling, I always check one more time for image size prior to saving. That is reflected in the last pair of numbers, with the now intact chain link symbol

When I first used Gimp I devised and explained this method for mosaic color separations in prior posts.  The expectation in working with such repeats is that on any rows there will be no more than 2 white squares marked side by side. On odd-numbered rows in the separation, the contrasting color squares slip, while on even-numbered rows the black squares slip. On odd-numbered rows, the main color (black squares) knits, on even-numbered rows the contrast color knits.
I think of row one/ odd rows as needing to knit black squares, row 2, and even rows having to knit white squares rather than marking in the traditional manner for slipped stitches on each row. I now have found a far quicker alternative to color separate for mosaic knitting using only GimpWorking on the black and white indexed repeat, use a magnification of at least 1800X. Using the rectangle select tool choose every other row beginning with the second one in the chart. That row will be highlighted by a white dotted line. Choosing will swap black and white cells in that row. Continue the process on every other row. It is not necessary to select the tool each time, as you advance and select the next row, the one just left remains briefly outlined in white dashes, making it easier to advance correctly in the design.
Import the black and white table, process as described, scaling for my final image to 16X32: This repeat posed by a quandary. The file may be used as-is and doubled in length after download.
Because of my personal preference for not using elongation when knitting pieces in these techniques, I tested doubling height in Gimp with no success at all. However, I was successful in doing so using 2 paint programs, both available for free download for Mac. The first has an amazing range of features, including the illustrated resizing options https://www.arahne.si/products/arahpaint/

and https://paintbrush.sourceforge.io/downloads/, which allows for scaling by percentages or pixels Comparing the results for the elongated repeat, errors in the first are obvious, there should be no white squares anywhere repeating for more than 2 rows Proof of concept A review of a design from 2012/10/15/mosaics-and-mazes-from-design-to-pattern/, separated this new way the repeat charted in Numbers tiled for repeat alignment check The repeat was color separated working in indexed black and white and shown compared with the punchcardwill result in missing colored squares in the final fabric, which may not be noticed until after eyeballs have had a rest. Here the final .bmp  repeat is also compared with the color image in the previous post It will need to be doubled in length for use with the color changer, the first preselection row is from right to left. End needle selection will ensure that each color knits the first and last needle on each side of the piece.

Binary alphabet knitting patterns

There are moments while surfing the net that trigger memories of long ago popular knitting patterns. One such is the piano scarf, usually knit double bed. For a while, knit QR codes, or even bar codes were “the thing”. Decades ago, long before online converters and easily available information, there were a few articles on converting alphabets to binary codes for knitting. Far more recent versions with different interpretations: using ones and zeros for pattern,  hand-knit  https://knitty.com/ISSUEwinter06/PATTbinary.html  A collection of machine-knit versions https://knithacker.com/2017/03/sam-meechs-  knitted-binary-scarves/I prefer the more abstract to the literal interpretation using numbers, happen to have a 12 letter first name, and thought I would go for converting it. Because of the number of letters involved, the repeat would of necessity have to be a vertical one. I used 2 converters to double-check the result, noticing that when one of the letters repeats, the code for each of the 2 letters is slightly different. Of the many choices, I used these converters https://www.prepostseo.com/tool/text-to-binary-converter,  and https://www.convertbinary.com/text-to-binary/
Each letter is converted to 8 digits, making results easily adaptable for punchcard use. 01000001 01101100 01100101 01110011 01110011 01100001 01101110 01100100 01110010 01101001 01101110 01100001. My spreadsheet in Numbers refused to allow me to enter the 0s at the start of each sequence, so the 0 has its own column, and in the larger chart, it is illustrated as a blank vertical row The problem if such repeats are used for fair isle knitting is that the results are likely to separate along those long vertical lines and to curl to the purl side even if blocked flat to start with. Converting the pattern for use on the double bed with any DBJ technique and backing is the better solution. My results, with letters from the bottom up Programming the width of the number of needles to be used for the “scarf”, allows for the addition of a border stitch (or more) on either side. Start the base with and use the dark color for your first knit row from right to left in most of the automatic 2 color separations.  Here is a tentative 72+1 stitch version If numbers are your preference, with a bit of playing around digits may be adjusted in width and height going a bit bolder, the 8 individual letters as numbers could repeat horizontally across each design row. A repeat for the letter AX2 planned for the first segment of an 82 stitch wide scarf, with the number of knit rows between each letter group started at 5. An attempt to visualize the final look using only the letter A.
G carriages may be used to knit the same patterns in knit and purl stitch combinations. 

Automated shapes across rows of knitting using slip stitch only

WORK IN PROGRESS

Full automation of “held” shapes using slip stitch alone is possible, involves careful planning of the design repeat, an understanding of necessary sequences in “holding” techniques, and results in large, long repeats for recurring shapes.
The starting side for preselection rows varies depending on the design.
Pattern knitting is worked with both cam buttons set to slip, end needle selection must be canceled.
All stitches on the knitting bed must be cleared with each pass of the carriage from side to side.
As shapes grow, test periodically for any yarn loops accidentally caught on the gate pegs.
The overall downloaded program needs to include repeats planned for the number of stitches in work on the needle bed. This is the standard requirement for Ayab, on my 930 the default img2track programming is for a single motif.
If working on an odd number of needles, whether the needle selection is pushed to the right or left of center varies depending on the brand of machine used and changes if horizontal mirroring of the design is added.
It is helpful  to begin with small, narrow repeats for practice. Assorted samples from previous posts:
a ruffle also using the garter bar a couple of zig-zags only one of many pleat variations that may be enlarged and planned for the width of the bed in knitting items such as sideways skirts repeats planned for texture bumps and slits shell shapes Testing the idea on a limited width with small intended shapes helps one iron out errors in logic or knitting sequences,  I prefer to start with a colored chart, making it easier to follow movements of the yarn, carriages, and color changes The chart was then loaded in Gimp, the Mode changed to bitmapped B/W, and the image then scaled to the final width of 74 X 96. For this exercise, I chose to keep the shapes equal distances apart (marked in green), mirrored the image on my 930 to produce the shapes in the same direction. In this instance, as is often encountered in lace knitting, an odd number of rows between repeat segments will allow for the carriage to start from the opposite side in order to reverse the direction of the shaps. The first preselection row may start from either side depending on whether the downloaded image is mirrored or not, whether by intention or automatically by the machine model’s auto settings. The default isolation in img2track is fine, ayab knitters are required to program the repeat in width to match the number of needles in use, so this would work for both I did run into an operator problem: had managed to save the repeat so rather than being all B/W there was a single row of color at its base, which caused mispatterning only when that #1 design row was knit.
With that amended, the selection problem was eliminated The same shapes always starting on the same edge A will distort that edge. Extra rows of the alternate color can vary shapes of the striping between them. Single shape rows could be floated much farther apart on solid ground, or one to which other colors or techniques are added, and finally, the reversing shapes produce a more balanced height at both sides.

Single bed tuck/ mostly slip stitch fabrics 3

As with the tuck stitch, the knit carriage ignores the needles that are not selected in the pattern. All holes in a punchcard, black squares, or black pixels in electronic programming knit. A great deal of dimensionality may be achieved since the tuck restriction of the maximum amount of yarn being held in the hooks of the nonselected needles does not apply. The effects on the width and length of the fabric vary depending on the number of needles ignored in the pattern. If slipping in long vertical areas, the yarn that is held in the non selected stitch(es) needs to be held for that long without breaking. Multiple colors per row patterns may in some cases require specific color separations, but as usual, a good place to start is with published patterns.

Stitch formation: the needle that is not worked holds a stitch that gets longer until that spot on the needle bed is selected again, resulting in a knit stitch being formed in that location with the next carriage pass. Floats are formed between knit stitches as the held stitches are skipped. The height and width of the bars created by unpunched squares or white squares or pixels need not be fixed and may be extended in both height and width, breaking tuck rules. Many patterns are impactful both with the use of single-color yarns or with color changes. With color changes, the elongated stitch carries its color up in that location on the knit side until it gets knit off (not always or necessarily in the same color).
Here stitches are held for 4 rows,  a planned color change on the next row would require needles that had been skipped, marked in red, being pre-selected forward for knitting back toward the color changer and returning to the previous or next planned color selection In textured knitting, fiber choice can be significant. It is best to use a yarn with some memory, such as wool. If yarns such as acrylics or rayons are used and in turn are pressed the fabric may become permanently flattened, which is not desirable unless it is a purposeful design choice.
Depending on the KM brand, the space between slipped repeats may be altered. In some cases, no matter what the programming method, and especially when using multiple colors, the length of the required repeats may grow exponentially no matter what machine is being used.

It is possible to use slip stitch in only one direction to create knitted cords, often referred to as i-cords. The technique is sometimes the introduction to using the stitch type. Used for all over patterning the possibilities for textures and 3D effects and shaping are endless.
Slip stitch patterns tighten the work widthwise, as well as shorten it in length. To achieve more drape in the resulting knit use a tension dial number 2 higher than that used in stocking stitch for the same yarn.
To retain a flatter fabric shape off the machine it may be best to slip no more than 2 side by side stitches. The number of rows for which stitches are slipped contributes to density. Some of the single bed patterns may be used double-bed as well, but the discussion here is for single bed patterning.
Some repeat ideas for working with diagonals from a punchcard reference, and one from the factory basic pack supplied with machines: Remember that punchcards knit the image as viewed on the purl side of the fabric, so to match swatch photos given in published pattern books, the same repeat, unless it is perfectly symmetrical,  will usually need to be mirrored horizontally for use in electronic machines.
Similar shapes to the above, arranged differently: in A,  arrows point to punched holes that create a vertical line containing 2 slipped rows followed by 2 knit ones, B is problematic because the long vertical white lines would mean the stitches corresponding to those locations on the needle bed would slip for the height of the punchcard, C is B color reversed to solve the problem, and suitable for slip-stitch knitting. An alternative for using B as is would be to have needles not selected in those all blank locations out of work on the main bed creating ladders (or transferred down to and in use on the ribber). As in any pattern knitting, if needles on the top bed are out of work, end needle selection must be canceled. If it is not, the needles adjacent to out of work needles will knit on every row, altering the planned pattern.
The same shapes can be edited for use after rotating the original The 24 stitch repeat for the bottom option is shown, punchcard knitters would have to punch the height x4. The minimum electronic repeat highlighted with a red border tiling to check the alignment of the 8X10 repeatMore repeats using similar lines, varying in density and consequently in their height:  all knit rows (no white squares) make for easy to recognize color change possibilities and transitions other possibilities using checks rather than solid lines When evaluating published repeats, keep in mind the basics; these are suitable for electronic KMs that will allow for color reverse punchcard knitters would have to punch white squares, resulting in this arrangement The knit side is not necessarily always interesting. With knit stripes in a different color breaking up the textured segments a secondary pattern will begin to emerge. A closer look at the samples below reveals one repeat is actually the other, drawn double length. This is an easy option, even in punchcard machines. When knitting long pieces especially, however, I prefer not to use double length built-in features, finding it easier to sort out where I am in terms of design rowss if errors occur

Returning to a couple of the tuck stitch illustrations, adjusting the repeats for use with the slip stitch setting. Some of the color change sequences are suggested on the right side of the charts The tuck stitch version,
modifying it for use in slip stitch B, adding all knit rows between repeats A, and visualizing color placements on the knit side of the fabric.   Depending on your machine ie Passap Duo requires 40 stitches punched repeats or modifying for electronics, vertical black columns or additional white squares may be added to the original design repeat units. The corresponding cells are filled with the color gray Testing the waters: a swatch using 4 colors,  beginning with color changes every 6 rows, ending at the top with every 2, more variations are possible.I have begun including .pngs with some of my posts. Check that your import method does not automatically change the mode to RGB. It is a common problem with such grabs from FB. If that happens, index the image to B/W and save again before using it in download to KM software.
Making those shapes move: color striping variations for using 3 or 2 colors are seen on the right of the chart. The final surface may also work very well in a single color The resulting swatch is shown sideways for the sake of space. I usually begin tests with some striped knitting so I can be certain the color changer is threaded properly, that each color gets picked up without crossing or other issues and that tension for any one color is not in conflict with that used with remaining colors. I am not a fan of the Brother single bed color changer, but it is a great convenience in fabrics such as these. A reminder when using it: add a lace extension rail on the left side. The carriage needs to clear the color changer far enough on its left for all colors to be picked up and changed properly From long design studio inspiration swatches: the secondary shapes are created by varying the number of rows in the color change rotation and placement, the bottom swatch shows the purl side of part of the completed length. Float counts can help duplicate the repeat or color placements if notes are skipped during knitting. Working with multiple slip stitch “bars”: this shows my punchcard, marked with color changes once the final rotation was decided, remembering to begin markings 7 rows up from the bottom for Brother (5 for Studio).  This design produces a fabric that is fairly flat on both sides: the .png is in the same orientation as the punchcard repeat, which you can see is produced with shapes reversed on the knit side in the swatches below it. Instructions on how the repeat was converted to .bmp for download using Gimp in post The working chart, along with an effort to visualize the location of possible color changes in order to create secondary patterns. Color changing on  “wrong rows” or starting preselection from the left rather than the right will result in random, not necessarily successful designs  This swatch segment illustrates the possibility of removing the slipped stitches from the needle bed and bringing them to the purl side, rehanging them on the same needles, bringing all needles out to hold before executing the next all knit row. The “floats” at the bottom of the swatch are from threads that were missed and not brought to the back of the slipped stitches

Attempting to visualize color changes using a larger, staggered repeat which makes more sense when the image is tiled Reducing the number of slipped rows reducing columns to produce a trim, being certain as to placement on the needle bed 

This repeat produces a ruched fabric when no all knit rows are included, and a sort of “honeycomb” effect when additional color changes on all knit rows are added. The first long swatch The working repeat does not need to be symmetrical, using space-dyed yarn may result in a surface with an unrecognizable texture 

Shifting slip stitch units to form shapes If the slip stitch units begin and end with the same color knitting just before them and immediately after, the color carried on the knit side will be consistent throughout. A sure way to get the shapes to match your design is to assign a number matching the number sequence in the color changer for your machine to each of the yarn colors. Imagining the results in a spreadsheet or even graph paper Expanding each section to 8 rows, the repeat now becomes 64 rows high and allows for 3 colors to show behind the slipped stitches in the chart on the left.  On the right, the color-changing order shifts to 6 rows at a time in the sequence 1,2,3,2,1,2,3. Design row 1 would begin the piece using the color red, the last row in the repeat is blue, shifting the color then carried up the front of the piece to blue

Once the basics are understood, changes in scale and amount of ruched textures along with fiber content are easier to execute The chart for the sample below is 30 stitches wide by 84 rows high, is shown turned counterclockwise This fabric has a more compressed shape, the blocks of slipped stitches are in a vertical arrangement directly above each other. A possible building unit for similar structures:  An all knit border on either edge will automatically create a ruffle on each side.

Here the repeats on the left need to be color reversed prior to knitting, punchcard users will need to punch all white squares, leave the black ones unpunched, and repeat all once more in height. On the right, some rows are omitted, reversing the color placement for the “solid” shapes with the next knit row. 

Blocks of slipped stitches (black squares in the chart, prior to color reverse) may be used to create 2 color fabrics that have no long floats in the ground color, electronics allow for more complicated shapes

If the goal is to produce specific shapes, then the way to achieve them is to use a color separation suitable for multiple color DBJ, knitting the fabric either on the single bed. The machine does not know whether the ribber is actually in use or not. Using DBJ software build in options or even the Ayab middle color one twice merit their own future post.

Single bed tuck and slip stitch fabrics 2: adding color

Any tuck repeat may be used in the slip stitch setting. The results for “safe” repeats executed in slip stitch may not be very textural or dramatic.
Though at times presented in color, the same patterns can be very effective in single colors as well.
Prior to testing multicolor patterns, I like to start the work with waste yarn, testing color changes there first, making certain colors are threaded properly, not crossed, and that the color changer is set up properly.
The Brother single bed color changer is unique, in that the yarn remains in the changer, not leaving it with each color change; its manual 
In the absence of a single bed changer, some fabrics may be knit with the ribber up, using the double bed model. This is the only option available for the bulky machine. There is a limit as to the amount of tucking that can be achieved successfully since the ribber arm does not have the system of wheels and brushes that help keep loops and stitches in place single bed.  Manuals

Instructions from the Brother single bed color changer manual 

For Studio/ Silver Reed

Punchcard volume collections are a great place to start to search for published repeats and subsequent DIY inspiration.
One such is Brother volume 5  Since the knit carriage needs to move to and from the left-hand side of the machine with each color change, an even number of rows in each repeating segment is recommended, but not necessarily required. The first preselection row is generally moving from right to left. End needle selection on helps the edge stitches knit. At times end needles will need to be pushed forward to knitting position by hand. Depending on how the repeat is placed on the needle bed, with some experience with a tuck or slip stitch, one can decide whether keeping the end stitches in the pattern creates a better effect at vertical edges. Analyzing 2 random repeats The respective .bmpsAs with all punchcards, the first and last 2 pairs or rows are not part of the design, they are necessary for the punchcard to roll continuously in the drum. Keep in mind that the card is reading design row one while your eye sees the row marked #1 by the factory on the card outside of the machine. Following the suggested color changes to match the specific swatch takes the guesswork out of the equation. In DIY or in trying a different color sequence, such guides may have to be shifted and marked accordingly. Specific color suggestions are given in the samples above in the left-hand columns. In #327 the order is in a variable sequence, which requires a bit more attention than #328. Follow the line below the #1 mark to the left, each card begins with color 1. Color notations in 328 are also next to those 2 all punched rows at the top. That is because those 2 rows overlap the first 2 design rows as the ends of the card are clipped together, front over back, for smooth, continuous, advancing movement. In 327 the sequence at the bottom would need to be hand-marked.
Before tackling patterns with moving components, these charts begin to analyze color changes in a ready punched or self-designed card which produces a honeycomb-like effect. The chart colors used are random picks from the palette, for illustration purposes only, illustrating areas where color changes may occur. The tuck/slip stitch held in the hook of non selected needles gets elongated and comes forward on the knit side, creating vertical lines in the color that is not knitting. The blue highlights the row where a single stitch, single row tuck or slipped stitch is created and the corresponding positions of the yarn on the knit side of the fabric Four tucked rows is probably the limit on Brother machines unless one is working in fine yarns. In the first interpretation, the ground knits for 2 rows on all preselected needles. In the second, the surrounds of the interior striping knit for single rows only at the top and bottom of the repeat. Electronic repeats A and B on the right may be as small as a single 4X12 unit.

The same card may be used, altering the color-changing sequence so the ground that will surround the tuck or slipped stitches changes as well. Using the same card would require a pattern start on card marking row 2, and an initial preselection row from the left to the right Keeping the 4 tuck row maximum the blocks of knit stitches between tucks can be varied, as can the movement of the vertical bars. The card repeat on the left would preselect from the right, while the repeat on the right would preselect from the left. So the card on the right is already punched, and instead of changing the colors outlining the shapes, one wants them constant and with a start from the right? The workaround is to advance the card to the last row in the full repeat, #36, lock the card, and preselect toward the color changer continuing to change colors in 2 then 4-row rotations after releasing the card. Tiling the repeats multiple times as with any pattern helps isolate areas where color changes might work as well as give us a sense of pattern movement across the fabric. With so many tucked rows so close to each other, it is best to use thin yarn. For slightly thicker yarn, one possible “fix” might be to simply eliminate one of the 3 tuck bars across the repeat, again check tiling for any errors, or places for color changes. Here the shift is not completed, some tuck bars were not eliminated the “corrected” repeat without additional rows, some possible color changes can follow the colored chart suggestions Moving on to electronics, playing with symmetry the repeat now becomes 30 stitches wide, the tiled image check for the unaltered version on the left.  The repeated adjusted two different ways in height to accommodate color changes in a few different spots Working with repeats with tuck or slip bars that are only 2 rows high make for easier use of a range of yarn thicknesses. There are some surprises to be found when color changes are made as often as every 2 rows, sometimes using up to 4 colors. The extra all knit rows may be eliminated altogether.
Beginning with a pattern that has large areas of black squares can help one understand what happens to the design as that knit ground takes on color striping in the same frequency as the color changes. The yarn used here is a 3/8 wool, making the fabric a bit stiff. The repeat is a larger cousin of card #327. Before the days of software tiling methods, on way to check repeats was to knit them up as Fair Isle. The large floats in this made it not its best use, the floats were sometimes caught with the companion color or looped. Had the long floats been consistently free, they could have been cut for a fringed look on the purl side and would have held in place well. Tuck knit in a solid color Slip stitch in all variations has purl side edges which curl to a greater degree, the short skipped areas were probably due to too tight tension of too quick a carriage pass to the opposite side tuck alternating two colors every 2 rows slip stitch  2 color variation slip stitch with the addition of a third color in the rotation Some patterns using color rotations every two rows are referred to as mosaics, mazes, or floatless fair isle. They can be deliberately designed, but there are treasure troves of working repeats in punchcard pattern books that produce visual cousins and may also knit up as lovely fabric in single colors, and wonderful surprises at times when one designed for single color is striped. A few to try that are pictured with corresponding swatches shown on the knit side:  from volume 5, the grey cells indicate the page numbers that correspond to the thumbnails in the downloadable version from Stitchworld, I have included repeat sizes, grey highlighted ones are suitable for use in punchcard as given Brother yarn changers are numbered, from right to left, and their published card designs color suggestions reflect that. The lace extension rail must be used as the knit carriage needs to clear the color changer on that side in order for the colors to change properly.  The Studio color changer color positions are marked with letters of the alphabet from left to right Some of the Studio punchcard pattern books showed both sides of the expected fabric assi\ociated with each card, here is a repeat that breaks the tuck rule of no more than one blank square side by side in any row.
This swatch pattern from a Japanese magazine illustrates the difference in the formation of the tucked loops when two blank squares exist side by side. The repeat is 10X22, colors are assigned letters rather than numbers here as well Another rule breaker: odd numbers of tucked rows with no added all knit rows. Experimenting with such repeats results in less organized all-over patterns, here colors are changed every 2 rows, every 4 rows A single knit row may be added, for an added variation with color changes every 4 rows These repeats take shapes in another direction which becomes more textural and interesting when blank stitch areas are expanded for use in slip stitch setting This pattern, with color changes every 2 rows and two-row tuck sequences has an assumed interesting pattern shift.  The tiled X2 horizontal repeats lined up side by side show that extra knit stitches have been added, shifting tuck stitch rows by one stitch in alternating directions, but just because it is published, it does not necessarily make the repeat correct. Those striped areas can only occur if there are solid all punched areas.  Keeping the constraints of a 24 stitch repeat, reducing the width of segments to 12 stitches rather than 24, the original repeat as amended The tiled results for each24X56 repeat proof of concept swatch in a far thinner yarn than the book photo An approach to designing such patterns can begin with a template for color changing every 2 rows and taking colored squares away to indicate stitches that will be slipped or tucked. Repeats can be adjusted from wider electronic ones to the 24 stitch width constraint for punchcard machines, as well as shifted to change the resulting shapes and their colors on the knit side. The two-dimensional charts are not capable of reflecting the amount of gathering of the fabrics or distortions of the stripes on the completed knit Japanese magazine publications often recommended many color changes, each for varied numbers of rows. Sometimes more is less. The number of colors may be reduced, and changing the numbers of rows used for each color as well can expand the number of fabrics produced from a single repeat. Good note keeping is a necessity if the intent is to easily reproduce the fabric at a later time.
Mixing things up for vertical designs:  Adapting punchcard designs for use in electronics becomes easier once one is familiar with the stitch structure. This is a cousin of 328, 13 stitches X 52 rows. Tiling as in all designs helps sort out errors or missing pixels. The “corrected” pattern, with the accompanying test swatches, the first knit in tuck stitch changing colors every 4 rows and slip stitch changing colors alternately every 2 rows, then every 4: My blog posts on working with and designing mosaics (suitable for tuck and slip) and mazes (slip stitch only, multiple side by side unpunched holes or white squares in any row), in reverse historical order

Single bed tuck and slip stitch fabrics 1

The main difference between the 2 stitch types is that in tuck stitch the strand of yarn on the non selected needle is held in the hook of the needle forming a loop, while in slip stitch the strand of yarn bypasses the non selected needles as the row is knit, forming floats between stitches Symbols commonly used for bothIn both instances the stitch on non selected needles when the pattern begins (blue row in photo) is held in that needle hook, growing in length until that same needle is selected, and with the next row of knitting (red) one returns to the standard knit stitch formation.
Both distort the fabric, the tuck stitch widens and shortens it, while the slip stitch narrows and also shortens it. Both are capable of producing textured, interesting fabrics on only one or on both sides of the knit depending on the pattern’s design repeats. Which side is chosen as the public side is simply a matter of preference. In accessories and clothing, the interplay and “reversible” effects can provide added interest.
Because in tuck knitting the stitches are being held and gathered, more rows will be required to produce the desired length in pieces. Because the knit gets stretched sideways fewer stitches will be required to achieve the wanted width, making it suitable where larger garment pieces are planned. Looking at the stitch in a 2D diagram: A– loops are created for 2 rows, the original stitch is shown elongated. Each patterning needle hook now holds 3 yarn ends. B– the needle coming forward prior to the next pass whether by card reader selection or by hand, will knit on the next carriage pass to the opposite side. C– the originally held stitch as it might appear on the knit side

The group of loops as they knit together then forms small lumps/ bumps, or what I think of as “butterflies”.

The capacity of the needle hooks in terms of the number of loops they can hold and the quality and thickness of the yarn used place quick limitations of the number of rows one may use for tuck patterning. The Passap system tolerates many more such rows than the Japanese model machines, where the limit is often 4 rows. Slip-stitch is far more flexible in terms of applied “rules”.
Brother controls for patterning in any model are by the selection of cam buttons that offer directional arrows on the carriage Some of the options:    and not often used, but worth exploring, the use of opposing tuck and slip buttons at the same time. As with any knitting, for needle selection to occur the knit carriage (also known as KC) needs to engage the belt using the change knob set to KC. End needle selection or not depends on the goal fabric. If KC is in use but no cam buttons are pushed in, there will be needle selection, but the fabric produced will remain stocking stitch.
Any tuck cards may be used in the slip setting, but the reverse is not true.
Functions are in the directions of the arrows. For example, if a left button is pushed in, the next carriage pass will form loops or skipped stitches while traveling from right to left on the non preselected needles, and knit stitches on all needles on the return pass to the right, aside from any preselection being present. If both buttons are pushed in, the knit will form loops or skipped stitches with each carriage pass on non selected needles until those needle positions are pre-selected again, and then the stitches held in the hooks of the needles will knit with the next carriage pass.
It is possible to create the stitch structure on any machine, including manually by pulling selective needles out to hold for X number of rows. Motifs may be short or long, all over or isolated, can be arranged vertically, horizontally, diagonally, in diamond, basketweave, and plaid effects, may be combined with the use of stitches on the opposite bed, and with needles out of work (OOW) on either or both beds.
Punchcards are restricted to a maximum of 24 stitches or factors of 24 in the width of the repeats and require a minimum of 36 rows if they are to be used in continuous patterning. In electronics, the basic rules should be followed, but a single small repeat is enough to program, the size of large non-repetitive ones is limited only by machine memory and mode of download.
Both fabrics like to be weighted evenly, and several rows of waste yarn should be used at the start of the piece prior to testing patterns. Because it will be wide or narrow and short, that is a consideration if the plan is to combine several types of stitches in the same garment. Gauge swatches should be larger than usual.

Boiling things down to black and white: in both tuck and slip automatic patterning, selected needles produce knit stitches. Punchcard knitters are required to punch a hole for every knit stitch, leaving only areas that will be forming the tuck loops or skip stitch floats blank on the card. In a published chart for the stitch is used, black squares may be used to represent knit stitches and rows, white ones the tuck or slip stitch locations. It is up to the user to determine whether if using a published source, color reversing the repeat in electronics, or punching out the all-white areas as opposed to black is required. In single bed stitch formation, if one knits with two or more empty needles in work side by side, it will quickly become evident stitches will not form properly on those needles without additional steps being taken. This remains true in tuck knitting, but not in slip stitches. Though there are some exceptions, the usual rule is to have no more than one unit in any row without a punched hole or black square/pixel on either side of it. Punchcard pattern books are a great source of “safe” repeats. Electronic users need to isolate and draw a minimum of one repeat, which may be quite small. If duplicating a whole card with fewer unpunched holes than punched ones, only the white squares need to be drawn as black, and later the repeat is color reversed. Punchcard patterns usually have two rows of all punched holes at the top and bottom of the card that will rest on the first and last 2 rows of the design repeat respectively, allowing for the card to roll continuously in its reader. Cards also need a recommended minimum of 36 rows. Brother #1 mark on the right is 7 rows up from the bottom, while the card reader is reading design row one inside the machine, out of view. Cards from other KM manufacturers may be used, but the starting row may differ, as was also true back in mylar days. Punchcard machines produce the pattern as drawn on the purl side. Some electronic models or download programs vary, may require the pattern to be flipped horizontally.

An easy way to start becoming familiar with the knit structure of stitches is to begin by working with “safe” design repeats, using a familiar yarn in a light color. Depending on the punchcard machine model year, the card on the left (1) was a standard Brother issue, the one on the right (2) not always. Both may be used to test all cam buttons and stitch types, card one tolerates elongation well, card 2 may meet some resistance with tuck stitch if the yarn is thicker than the needle hooks will contain easily. Converting the cards to black and white pixels: the small single repeats for each card are highlighted with a red border. Depending on the method for programming the electronic machine, however, the single repeat may have to be repeated horizontally to match the number of stitches to be used in the piece. The third repeat is a hybrid of the previous 2, the start of making what is published more personal Studying published sources makes it easier to design more personal repeats. Cards that are “safe to use” can get one started in examining the texture and developing an understanding of how stitches are formed. They are often composed of variations of either card 1 or card 2 with added black areas. Using punchcards supplied in the packs with respective machine models appropriately can easily be done Additional published cards are also easily found increasing the number of tucked rows and observing the rule of knit stitches on both sides of the single unpunched squares resulting in no preselection.  Below, some of the single repeats are outlined in red. With additional rows now tucking, the added insurance of having them knit off properly at regular intervals is achieved by all punched (or black squares) single rows, highlighted with orange squares on their left. The black border isolates the actual patterning rows in the designs. Again, the top and bottom pairs of all punched rows are not part of the overall design but are necessary for the punchcard machines to line up patterning for knitting a continuous design The blank vertical areas may be arranged moving across the repeat’s canvas in a variety of ways. In this chart the tuck symbol is evident, some of the knit stitches around each tuck series are highlighted at the bottom of the chart in green, the single electronic possible repeat is 4 sts by 12 rows What may be confusing when symbols and charts such as the above are encountered is that the very first row of the symbol actually rests on the spot where the knit stitch that is being held for the next 3 rows rests, so design row 1, 5, 6, 13, etc are actually all knit. The punchcard minus the all punched rows at its top and bottom:  The factory-supplied blank cards may have arrows on the left, familiar in lace card designs. In the above case, the implied use is that the card start in the locked position on row 1 with the carriage on the right, preselecting to the left. If only a single color is to be used starting side does not matter. If regular color changes are recommended, more often than arrows dots, or color numbers are used in that column to indicate color change locations.  In Brother machines, the first preselection row may be made from either left to right or right to left, depending on the fabric being created. With the exception of dbj using the KRC button or patterns that expressly specify the starting side, most patterns using the color changer will need a start from the right. Here if that is done, color changes could occur every 4, 8, or 12 rows using 2 or even 3 color sequences.
There is another issue to note. Counting up design rows from the bottom the card is marked row 1 five rows up. This is a Studio punchcard. If using it on a Brother machine, the starting row would actually occur with the card locked on row 3, color change row markings if given, would have to be altered accordingly.
Distribution of tuck stitches can occur in groups, or more sparsely. The card on the right begins to break the rules with 2 needles tucking side by side for 3 rows. Those areas create floats akin to those created by slip stitches as the side by side loops drop off the needles in those areas rather than knitting off together. As areas of white become less balanced, punchcard knitters may find it easier to mark the tuck bars and punch all else, electronic knitters draw the white as black, and color reverse.

Few tuck stitches amidst lots of plain knitting are likely to not distort the fabric very much or produce a noticeable texture. The fabric will lie fairly flat, and approach a width proportionately closer to that of stocking stitch using the same yarn. The outlines can serve as markers for the introduction of additional hand techniques ie tying objects or beads in the center of the shapes after knitting and prior to felting in order to obtain surface bubbles of non felted stitches, or marking areas for duplicate-stitch or other embellishments.

In some instances, thread lace repeats can provide DIY inspiration. With the color reversed, the structure for possible tuck can be observed and determined if suitable. In the bottom right image, those white solid lines are the easiest edit, shown in progress With the basic structure recognized, weaving punchcards may be suitable, not all need be color reversed. Electronic repeats may also be used directly or adapted for use on punchcard machines, providing the repeat unit is a factor of or up to a maximum of 24 stitches in width, which translates to 2,4,6,8,12, and 24, and repeated to the recommended minimum of 36 rows in height. For tuck stitch, those narrow vertical bars surrounded by black squares are the common factor. The StitchWorld pattern book charts require only matching a usable width for use in punchcard models since the knit stitches are shown as black squares. Here is a random selection 253 translates easily to this, it would need to be punched twice 251 is a bit more problematic. Half the repeat is wider than 24 stitches. Here it is readjusted to 24 stitches, the height is 32 rows which may just barely squeak by punched only once the repeat tiled to check proper alignments This repeat is from a Studio mylar sheet. It also may be used in punchcard machines after removing 2 columns, since only half the repeat is necessary, and it is 26 stitches in width. Color reverse is necessary. In electronic machines it is easily accomplished with a command or the flip of a switch/ push of a button. The white squares as given would produce loops on all the corresponding needles, with no stitch formation in those areas.  I chose to eliminate 2 columns from the blocks on the left. Tiling shows the amended repeat’s appearance, with the color reversed image for actual knitting to its the right. Repeats with a balanced number of black and white squares provide all over textures in fairly balanced fabrics. As the number of black squares on a field of speckled tuck stitches grows, the knit shapes may actually poke out from the surface of the knit, since those areas are not gathered in the same way as their surrounds. Yarn properties and tension also have an effect.
Design with very few black vertical single stitch “bars” are commonly found in patterns published for electronics, often also too large for for use on punchcard models. As with lace, where there are few black pixels on large fields of white, caution in trimming the image is necessary. Tiling once again helps one locate possible errors. An example of such an image tagged as being 42X62: tiled 42X62adjusting to avoid those 4 rows tucking consecutively, now 42X60Designing your own can begin with the choice of a template, such as this one, 24 stitches by 36 rows.  To begin with, I added a rectangle to the full template repeat on the left. To its right, the size of the rectangle then begins to be altered along with the addition of some all knit rows.  The center illustrates making certain the 4 stitch repeat aligns properly at the top and bottom of the new repeat. The test final repeat image is on the right. Working with a different shape, using copy and paste to place it,  adding a brick variation on the right, for punchcard full repeats of 24X40The matching electronic repeats for both, unless your download requires programming for the total number of needles in use:
