Translating Passap model book pattern/use on Brother 1

A facebook member recently shared this photo, followed by a “wish I could make it” comment, it is from the Passap #60 pattern book.I began a spreadsheet on my blog intending to update it over time that may be useful when traveling between Brother and Passap 
The style in the photo is that of a generously sized dropped shoulder sweater. I will not share pattern instructions but will try to interpret some of the possibilities for knitting it as written or for achieving similar textures on the Brother machines To start with, you will note the recommended test swatch size is 100 stitches by 100 rows. When gauge matters as in dbj or heavily textured knits, this is a necessity. In turn, math calculations also become easier in metric. If using the knitleader I have sometimes reduced the swatch size to 80 stitches by 80 rows. Even for scarves where calculations may matter less, when transitioning from smaller gauge swatches to larger stitch counts there can be surprises. What knits on 60 stitches may refuse to do so on larger stitch counts, requiring tension and gauge adjustments. Although Passap promoted that it knits easily with no weights, I always cast on with ribber cast on comb, and then, if needed, the addition of weights may be easily made.
Strippers, which push down on the knit from the lock as it moves from side to side, have no equivalent in Brother, where weight is an absolute necessity when working ribbed fabrics. Stripper handles come in varied colors: orange is for double bed work, black is for single bed work, blue is for very heavy fabrics. A suggested rule of thumb is that if you are knitting on both back and front bed in a stitch pattern where several needles in work are opposite needles out of work use black strippers ( 3×3 rib or cables and Aran work would be examples). Sometimes spacing between the 2 beds will make black strippers harder to use, other times 2 different types may be used concurrently for best results.
As the size of the piece changes ie. in shaped sleeves, any weight must be adjusted proportionately to keep the gauge constant in order to avoid sizing surprises.
The Passap is a true double bed. The image on the left is of the Passap locks and on the right, of a stripper. The position of the beds is reversed to the Japanese, the knit bed is in front, the “ribber” in back. The locks (carriages) pr select pushers, they, in turn, select needles akin to Brother pre-selection. That is the reason why the Passap needle set up diagrams include more information bits than those for Japanese machines. Additional details for any of the above are only provided in publications if they are necessary to create the particular stitch type. That said, one is free to add a knitting bed or alter lock settings simply based on the goal for the piece and an understanding of what black and white squares “do” in a pattern download. Looking at the Passap back lock, one can see the larger variety of the equivalent of cam button settings in Brother. The Passap buttons also referred to as arrow keys at its very rear make altering and automating patterns on the back bed easier and possible in a far wider assortment on any number of needles. The Brother lili setting, the equivalent of the #1 punchcard, must have an even number of needles in use on the ribber.
The arrow keys on the back lock reverse the Passap position of the pushers. Pushers that are down are brought up, pushers that are up are brought down. Arrows reverse when knitting in the direction of the arrow (think Brother preselection row), but cause needles to perform that function that same row. The O button releases any arrows, therefore pushers remain in the same position. N will knit disregarding arrow selection on the back bed. One arrow key reverses the pattern every 2 rows, 2 arrow keys do so every row.
Slip setting with pushers on Passap E6000 back lock is also BX, on the front lock it is LX. That differs from diagrams in the model and pattern books and magazines, which generally refer to Duomatic (Passap punchcard) settings. The assumption in the directions for the E6 is that the built-in techniques will provide you with LED prompts for any of the lock settings matching them to the right of schematics for the DUO, rather than that you would attempt to knit the pattern in some other way or on a different KM brand.
Scrolling down the pattern: Pintuck Pattern A: Deco card 77, E 6000 # 1130, technique 251No pushers are illustrated. Back bed (N) knits every row. The front bed is set to slip in both directions (BX on Duo, LX on E6), pushers will be selected in the pattern by the console. When using Tech 251 two rows are knitting on the front bed forming pintucks where there are black squares in the stitch pattern. Brother probably would reach its limit with the original 1130, might be able to handle a thin yarn in a repeat slightly wider and taller. The Passap repeat becomes twice the length but is unaltered in its width. My swatch has an extra repeat before switching to normal knit, the red line highlights where the trim would have ended. The blistered pockets will appear as knit textured shapes on the purl side. The knit side will show a pattern of elongated stitches created when those needles are slipped. The red line in the photo shows the approximate ending for the repeat used in the trim in the magazine, I was on a roll and kept on knitting.
Pintuck pattern B: Deco repeat is 20 stitches wide (Duo cards are 40 stitches wide)The directions at the time the model books were written for knitting with the console were designed to have the knitter work with built-in patterns and then to use the alter possibilities to manipulate them to achieve the same result as the punched holes might in the final repeat in the Duo. The Passap console had a card reader that operated with sheets that were in turn inserted into a sleeve and were drawn on with “special” pens. C6, proprietary early software that operated with a dongle, came a bit later.  There was a large factory built-in pattern library, and the manufacturer, Madag, supplied free files for the Duo pattern books in formats that could be used with the program for “easy” download. The 910 had variation buttons and instructions for combining multiple patterns using the factory-supplied mylar sheets. The intent was to allow the knitter to maximize the use of both. I honestly have avoided altering patterns that way intentionally most of my knitting career, finding I simply prefer programming black and white squares for the function intended, which for me is easier to visualize and reduces errors. The trend explains the E6000 instructions in the magazine, but in fact, the 20 stitch repeat as drawn can be downloaded and entered as-is, bypassing the alter loop manipulations. Technique 253: a pintuck is formed where there are white squares. For each row of squares, one row is knitted on the front bed. Pushers will knit for one row, rest for 1 row. 1124 is the console built-in pattern used in my test swatch and below it, its mirrored image tiled repeat to get a sense of the movement of the triangles:note: the direction of the chart pattern repeat for 1124 is reversed in the blisters. It appears as drawn on the knit side of the fabric, where stitches are slipped and elongated to create the pintuck texture on the purl side 

In the Duo HX setting the front bed normally knits or slips according to the design for one row, and slips the next row. Again, the chart illustration is for the Duomatic and the lock there takes over the function performed automatically by the E6 technique. The back bed in this instance knits every row. In the E 6000 the front lock is set to LX (slip <– –>). The fabric created may be referred to as blister or pintuck (nothing to do with tuck stitch/brioche). The bubbly texture appears on the purl side. Stitches that slip on the bed with needle or pusher selection elongate, pulling extra rows together eventually, helping to form pockets that are sealed periodically by all knit rows. With pushers down, no needles selected, the front (knit) bed skips/ slips associated needles. With the back bed (ribber) set to N, its stitches will knit every row.

Pusher selection is down when front bed slips (akin to no needle  preselection on Brother)This selection happens between each pattern row, as the design is advanced This shows the pattern as knit on the Passap, reduced to black and white squares Taking a closer look at the pintucks on the sweater body Going for the safe repeat on Brother machine: color makes a significant difference in how visible the pattern will be. Both yarns are supposedly the same weight, the white was hard to knit, and there was a needle that dropped stitches regularly. The blue yarn knit with no problem here the repeat is rendered twice as long, and the texture becomes more visible a sideways view:The last swatch in the series: I am now able to use Ayab once more, img2track is having issues for me with its use on the 930. My repeat, therefore, is planned for the maximum width I may wish to test knit on the 910 machine, emulating tech 253. Every other row there is no needle selection on the main bed except for first and last needle if KCI is used. On those rows the ribber only knits, there are more rows in the blister “pockets”. I knit the sample quickly, not checking every row, and in this instance had two dropped stitches on the main bed, and no breaks. Yarns with memory ie wool are the best for texture retention, acrylics such as my blue yarn would flatten permanently if pressed, resulting in a very different fabric. It takes experimentation to sort out whether the extra step is worth the effort or is problematic during lengthier knitting

In summary: Passap E6000 knitting techniques 250-255 are used to produce pintucks.  When using 250, 252, 254, the pintucks are formed on the back bed on the needles that are opposite those with the pushers selected down in accordance with programmed black squares.  The corresponding odd numbers 251, 253, 255, select pushers down according to programmed white squares (253 in the manual should say white, not black squares). Since the pintuck is formed on the back bed, setting it on FX (Tuck) may also be used, the pintucks then become blurred, producing a fabric which is wider. Width of the resulting knit may be significant when producing garment panels. One option in cross-brand might be to use every other needle selection on ribber, with its carriage to tuck in one direction, knit in the other, resulting in a spotted pintuck. My Passap manual is filled with scribbles, often including notes on alternate fabrics produced with same technique numbers.

Returning to the specific sweater pattern: below the back bed is set to GX in the first 2 instances, which is akin to setting the Brother ribber to slip in both directions, no stitches are knit. There are no pushers or needles illustrated on the back bed, so the implication but not necessarily the fact is that these are single bed fabrics. How to transition between them and the double bed would need to be considered (see notes at end of the post). The pattern is an elongated one, using slip stitch and color changes every 2 rows, carrying one color at a time. Again, on the E6 front lock Duo BX is LX, arrow key function on the front bed is replaced by the technique console instructions. The E6 front lock has no buttons or arrows.
Tech 176: knits one color selection for 2 rows, then the alternate color selection for 2 rows; Pattern 1100the Brother equivalent in the next sample the same repeat 1100 is programmed via the console and enlarged  <–> X2, which means in the number of stitches onlythis is what will be knit, translatable to Brother, also with color change every 2 rows

Tech 183: long stitch backing, back bed knits every stitch, every row. Brother would require the separation to be made for the elongated triangle to match the Passap knit where each design row color knits twice in succession. Ribber or back bed settings could be altered to suit if preferred.
The shawl is what some may call a scarfThe above is the first illustration showing pushers on the back bed in alternate positions of rest (down) and work (up, toward the front of the machine) in groups. The pushers here at the end on either bed create the colored border on each side. The selection is opposite to the one on the end needles on the front bed. When the latter pushers are up, the back bed are down (slipping/not knitting), when they are down (not knitting the color in the yarn feeder), the back bed are up. This is an instance where to achieve the same, hand selection would need to happen on the Brother ribber on every row, or 2 sets of paired carriages, each carrying a color, could be used. Tech 181: is used for double bed fair isle with background color only on the backside. To seal the edges usually the first and last pusher on the back bed is brought into work, here 2 are used, creating a 2 stitch contrasting color border. Color is changed every 2 rows. To me this is an instance of because it is published, you may still not want to knit it. This is the first-row initial needle and pusher position on the front bed It is altered every other row (same is true on the back bed with the arrow key in use). My blue yarn is the body color, the white the border one. I only knit a very few rows, but that is enough to observe what is happening:  the blue knits everywhere but on the stitches intended for the contrasting border when the border stitches knit only on each side, floats are formed the width of the needle bed between border stitches for two rows they are then enclosed by the next row of blue every needle riband there is considerable bleed-through of the white on both the knit and the purl side of the fabric

Tech 183: is double bed fair isle with striper backing. It essentially knits the elongated pattern 1130.

One then comes to actual knitting and putting the pieces together. Instructions are not always clear. There are several transitions in this piece. The trim at the bottom of the front, sleeves, and back is a double bed every needle rib that transitions easily from one textured pattern into the next. Its purl sides face the outside. The same is true for the back and sleeves, both are both knit from the trim on up. The front top portions are knit sideways as are the button bands, and they are in turn joined to the mixed stitch type “front border”. The “front border” is puzzling.  Since the geometric pattern shows on the “knit” side, the trim by default then would have the slip stitch front bed pattern showing on the outside in order for it to transition directly to DBJ, not the pintuck. Looking closely at the photo there is a clue that that is indeed the plan in that the edge closest to the cast one has the triangles at the start facing in the opposite direction of that in the test swatch purl vs knit side.
I also see extra colored hems in addition to patterned “FI” ones. The back bed can be set to slip (GX), the patterned section knit on the front bed, then the back bed returned to knit to seal the hem. This is not indicated in the schematics or the written directions. The same can be done with added solid color changes (purple and blue in the photo), knitting several rows on the front bed, then sealing it with a return to N on the back bed. That same row can also be planned as a selection row for DBJ. I am still knitting my swatches in 2/24 acrylic, which is also not always the best to use. If I were to knit the piece, the cast on would get some work on it, as well as the tension adjustments for each fabric segment.

Pattern 1130 is also used in the same issue # 60 in the body of a man’s sweater. In using Tech 250 pintucks are formed where there are black squares in the stitch pattern, for each row of squares 2 rows are knit on the front bed, elongating the pattern X 2

The Passap magazines generally also included a strip of heavier stock paper with samples of the yarn recommended for the particular pattern ie this one from another issue, which facilitated substitutions and provided a better sense of color than the garment photosBrother ribber and DBJ settings reviewed  including for solid color backing.

Because of the Passap capacity for heavily textured stitches, many of their early pubs included several patterns for use with tuck or slip stitch settings. This issue is dated 1990, may be found with accompanying pattern instructions in French online, the sweater on the right uses a pintuck pattern with appliqued pockets in a  different knit structure the repeat is 20 by 20 stitches wide, E6 Tech 253 is suggested, white squares form the pintucks, the same technique used in my sample knit using console design 1124Working with simple shapes such as triangles can be an easy way to help one begin to understand how various techniques build up stitch or row counts, altering the original. Several of my DBJ posts are written using a cousin of pattern 1130 and include images of corresponding swatches executed on the Brother machine. In Brother, with rare exceptions (such as when needles are left out of work while in pattern) black squares (punched holes) knit, white squares (unpunched areas) slip. Slipped stitches are held until a black square or punched hole is reached, getting longer while the stitches on the opposite bed knit every stitch every row with that bed set to N/N. It is helpful to be using a yarn that does not break easily. Pockets are created of varying depths. As with any knitting, the color reverse option may produce an interesting variation or a “disaster” depending on the original motif. In the above chart, if knit as is, white squares would be slipped for 1-9 rows. Blisters of knit stitches will appear on the purl side. Tiling helps visualize the movement of the design in repeat.

In the color reversed image the number of consecutive white squares is now increased along the center lines from 9 to 11 its tiled viewthe expanded view of the original repeat emulating tech 253 now increases the height of the pattern to 40 rows from 20and its color reversed equivalent

In both expanded repeat variations of the “pinwheel” black squares create knit stitches. In double bed knitting, this seals the layers created by each bed together. The original design would create large pockets/ blisters, while in its color reverse version white areas would slip for one row, keeping the pinwheel effect, but the fabric will be predominantly sealed together. Thin yarn use is best, I used a 2/13 wool.
The original 20X20 design is shown on the knit side Left, its color reversed result on the knit side, Right. The elongated slipped stitches are noticeable on both purl sidesUsing the expanded 20X40 repat I did not have a slipped stitch issue such as yarn breaking, but because the pockets were so deep and so many stitches on the ribber were knitting for so many consecutive rows, the ribber stitches began to refuse to stay on their bed. I got this far: large knit area can be seen, as well as slip stitch loops Can the same expanded repeat be used in another way? The color reversed version results in a subtle large scale pattern that might be quite interesting in a shiny rayon or other fiber To review: Passap E6000 knitting techniques for pintucks are numbered 250-255. When using 250, 252, 254, the pint tucks are formed on the back bed on the needles that are opposite those with the pushers selected down in accordance with programmed black squares.  The corresponding odd numbers 251, 253, 255, select pushers down according to programmed white squares (253 in the manual should say white, not black squares).

On any machine, the size of the pleat creating the ripple/ pintuck depends on the number of rows that can be knit on the all knit bed before the fabric begins to ride up and becomes difficult to retain on the needles in work. Tolerance depends on knitting machine brands as well as the type of yarn used. Bold patterns read better than smaller ones. Weights are usually helpful. The Brother Ribber techniques book (now available for free online) addresses the topic on pp. 20-22.I have added a few patterns from published sources in a flickr album , most take into account any single stitch not being slipped for more than 4 rows. Doubling the length if using electronics is not recommended. These fabrics may be created in combination with needles out of work.

 

A return to short row shapings: bumps and slits

One is limited to imagination, skill, and patience when working short rowed fabrics. The techniques may be used in borders, on isolated areas, symmetrically or not, and the yarn, in turn, may be able to be pressed, stiffened, felted (which minimizes any slits), or otherwise processed to achieve desired effects. The scale of the shapes affects both the final look and purpose. Development for large sculptural pieces is very different from that used if one is aiming toward a comfortable, perhaps even flattering variable in a garment, but both can blend for interesting one-offs or even collections.

The usual conventions apply: stitches are brought to hold opposite carriage side, or floats will be created, indicated by yellow curved linesThat is a rule that may be broken when planned angles require decreases every row and a decision is made that such floats and their respective width are acceptable.

There are many more variations of the patterns I have previously referred to as “wisteria”. This is one, using different (2) width repeats in a systemic manner across a piece. I find myself going to a spreadsheet prior to any actual knitting nowadays. Low tech can achieve the same, and be as basic as colored pencils on graph paper. Representing actual rows knit would make for a very long chart. This is a compressed version with red representing rows knit on that portion of the needles in work, the other colors for each of the 7 and 9 stitch repeats respectively some sense of how repeats would line up, again not to proper scale To knit: cast on and knit at least 4 rows on the desired width for the planned piece. I prefer to end COR, but directions could easily be reversed for a start from the opposite side.
The row counter may be set to 0 and used for each segment, or the tripper for it can be turned off as preferred. With labor-intensive fabrics, I sometimes calculate based on a minimum number of repeats rather than row counts. The gauge can be even more difficult to calculate even if rows are tracked somehow. In addition, the choice of yarn, its weight, whether each segment is weighted down or not, the tension in masts and carriages all can make the result uneven or harder to predict. Use of claw weights is a personal preference. I prefer to avoid them whenever possible. They can help control the length of the slits at their side(s), but sometimes distort the length of the knit stitch on either side of them. COR: set the carriage to hold, bring all the needles to the left of the first group of 9 needles to hold, knit 12 rows (even number), returning to the right.
COR: push back to knit groups B (7stitches ) and C (9 stitches) to the left of A into work
Knit one row to left
COL: bring A (9 stitches) and B (7 stitches)  to the right of C out to hold, knit 11 (odd #) of rows on C, ending with COR once more (one row had already been knit on those stitches, so the total remains constant).
Repeat in groups of 3 as described in the last 2 steps across the row ending COL
Knit a few rows, ending COR
Bring the first group of 9 stitches on left out to hold, knit one row to left
Bring all stitches to the right of the first group of 7 stitches out to hold, knit 12 rows, ending COL
Bring the next two groups of 9 and 7 needles out to work, knit one row to the right
Bring the remaining stitches to the left of the new group of 7 out to hold, knit 11 rows (odd #), ending COL. Continue across row. At the end knit a few rows, ending once more on the right.
I found at least 3-4 rows were needed between sections of segments to achieve shapes that did not meet to create extended slits with threads across them and to achieve a look I preferred. The interim all knit rows could serve as the opportunity to add other stitch types or techniques including purl ridges on the knit side, which could be achieved easily enough with a G carriage, but may prove perilous with a garter bar.
The needle bed or the needle tape may be marked with a water-soluble pen between needle groups to help make tracking easier.

Proof of concept purl side knit sideslightly scrunched upwith a touch of steam and light pressing

Planning your own pattern in scaled-down numbers of stitches and rows is good practice, may also lead to pleasant surprises. As with any tests, keeping notes while in progress is well worth it. What may be obvious while knitting may escape recall after the fact.  Then there are “little things” that factor in as well. For decades I knit on a 910 or a punchcard machine. On the 910 settings stay as preferred unless changed manually. In my electronic default, the repeat direction was set to be as seen on the knit side, on the punchcard, it is fixed as seen on the purl. At one point I received an orphaned, frozen 930 that I was able to get moving following online video advice. I have often forgotten to set the number one variation button or to change the default isolation to an all-over one in knits where that mattered critically. If programming a repeat, the starting side for a preselection row matters and it will change based on which side of the finished fabric reflects your planned motif.
The start of an idea with points to be considered,  some observations and questionsWorking it out on a spreadsheet: arrows indicate the direction in which the carriage needs to be moving, I prefer to start COR, the image can be flipped horizontally for starting with COL. The repeat is outlined with a thick border, is too wide for automating for punchcard, but as hand technique variations can be endless. To produce longer slits and raised shapes, add even number of rows to the red colored blocks, for more distance between raised motifs, add even number of rows to the side to side all green areas, maintaining the directional arrows. This is the isolated repeat for converting the pattern to a file suitable for downloadand its mirrored version for knitting from the opposite sideMy test swatch was knit on the 930, using img2track. Because not every needle on the bed is in work throughout the knit, end needle selection must be canceled (KC II). The knit carriage after the preselection row is set to slip in both directions. Because only a few rows are knit on the red blocks in the chart, the result is subtle. The white yarn used in many of my tests happens to be a 2/24 acrylic, so on the too thin side, and likely to be well flattened if pressed.
Often, the edge stitches on the carriage side will tend to be a bit tighter than those formed away from it. The same repeat may be used to create very different fabrics. Eliminating the all knit columns on either side of center produces a piece with “ruffles” on either side of center as the outer edge of each shape is no longer anchored down. The principle was used in knitting “potato chip” scarves popular in both hand and machine knitting for a while. Having a repeat on one side of an all knit vertical strip creates a ruffled edging. Note the effect of the added all knit rows on the “wave” of the piece on the right.

Many patterns are published for hand knit variants as well, Lion Brand Yarns offers the opportunity for learning both knit and crochet stitches. Some patterns are free with login (website info access is also free). Here are 2 such designs with slits and bumps to the maxThe shapes for the “bumps” may be changed, moving away from rectangular formats. Small repeats are used for the purposes of illustration here, but they, in turn, may be scaled up, rendered asymmetrical, vary in placement, and more. My design steps began with this idea

Following the goal to achieve bilateral placement along a central vertical knit strip, with vertical knit strip borders at either side, here shapes point in the same direction
Aiming for shapes pointing in opposite directions, following those arrows for “pretend knitting”,  a repeat is highlighted with a dark border on the left, while to its right placement for extra rows of knitting is suggested (must be even numbers). The repeat is then isolated and “grabbed” for use in GIMP

 

 

 

 

 

 

 

 

 

In gimp the bucket fill was used to fill all colors to black, the image was converted to bitmap BW, scaled and then knit. This is the final repeat usedI ran into an interesting problem for the first time. I had entered the row and stitch counts on my chart, used those counts to scale the image used for my repeat down to size for knitting, kept getting floats where there should not have been any, could not understand what the error in the repeat might be. What was happening is that because of the wrong row number used in scaling, there was an extra pixel row in the first test swatches resulting in knitting errors. The final repeat is 29 stitches wide, 38 rows high. This is the resulting swatchOnce more, the repeat could be reduced down to eliminate side knit strips, or limit shapes to one side only for a one-sided ruffle. What about repeating the same slit horizontally across a row? Repeats become very long, arrows are once again guides in knitting direction.  An even number of rows (green) at the end of the outlined repeat will return the carriage to begin knitting it from the right side once more. An odd number of rows added at its top will prepare for knitting the motifs beginning on the left.Again, motifs may be brought closer together, laid out directly above each other, brick fashion, mirrored, or as otherwise desired. Adding rows at the center of the shape will make the “smaller” eyelets at the corner larger as well as the ones created by its outer edge. Possibilities are endless. If automated slip stitch is used, it is the selected needles that knit. This is my final test repeat, flipped because I insist on forgetting to turn on the #1 variation button on my 930, and I like to begin sequences from the right.BringingBPushing unwanted needle groups back to D position will make them knit rather than being held, is another way to vary the texture distribution across any single rowIt is possible to add color changes between or within pattern repeats as well as needles out of work. A free pass may be made to the opposite side by bringing all needles out to hold, and once there, returning the next group of stitches to be knit into work. If electronics are in use for automated patterning, the carriage may be removed from the needle bed and brought to the other side before continuing.  If a punchcard is in use, an odd number of rows will need to be programmed for one of the colors in order to maintain proper needle selection. Repeats in charts below are for illustration purposes, not fully worked out repeats. Adding color stripes, with or without ladders Needles out of work with lateral transfers alternated with needles returned to work will add eyelets to the piece and allow for every needle stripes of colors (or plain knit). If a lot of eyelets created from needle transfers are in play, it may be necessary to change the direction of those transfers.It is also possible to combine patterning and holding. As needle groups are brought in to and out of hold, the needle selection must be maintained in order to keep correct patterning. There also seems to be a sweet spot in most machines for how far back a needle needs to be pushed for it not to “bounce” to an undesired position, thus picking up and knitting in the wrong color or dropping stitches off. Some variations also found in as to how far the active knitting needs to be cleared with each carriage pass on each side. One row in my test swatch has obvious extra stitches in white, my feeder B color. I am not certain as to cause. Introduction of patterning adds yet another layer of complexity to track. Once again I am using 2/24 yarns.

Mosaics and mazes charting meet Numbers, GIMP, and DBJ

A category search for machine knitting/mosaics and mazes design will lead to my previous blog posts on topic.
Previous posts on working with Mc Numbers include: knit charting using Numbers 2  which covers basics, keyboard shortcuts, and more,
Numbers to GIMP for creating images for electronic download  , charting knits color separations 2, charting knits, color separations 1, lace mesh motif charting, charting knit repeats using numbers 1, visualizing knit cables, knit graph paper 

To knit these fabrics use one light color and one dark for major contrast is recommended. Matching the dark yarn to dark squares and reversing their positions may produce interesting optical variations. The resulting knit has reduced floats and is not as bulky as traditional Fair Isle. Many patterns published in punchcard machine pattern books will produce such patterns when knitting single bed, changing color every 2 rows. White squares need to be 2 rows high, no more than one square wide. A page from one such reference:What appear as a maze designs in the swatch photos below would actually be unsuitable for use in the mosaic separation discussed in this post. The cards are designed for tuck (or slip) with color changes every 2 rows. The approach for planning and charting out such fabrics would be a very different one

There are a few rules in designing your own: in mosaics, the odd grid rows should contain single or dark-colored squares plus any cells used to create horizontal lines. The even grid rows usually have single or adjacent light squares but only single dark squares. As with any other fabric access to electronics allows for use of small repeats that can be color reversed or lengthened X2, whereas punchcard knitters need to meet the usual constraints in motif size in width and height. Tile features in software can often give clues to errors such as skipped cells or edges at top and sides of repeat that do not line up, avoiding having to actually test the repeat in knitting to evaluate the same.

Pre-drawn motifs that require color separation are available in a variety of sources. Kathleen Kinder published 2 books with repeats one for 24, the other for 20 and 40 stitch punchcards, inclusing isolated electronic repeats as well.

The original “swatch” inspiration for this post and its repeat were pictured in Mosaic Knitting page 110the numbering system reflects every other row worked alternating sides of the workit is shown here with a superimposed table grid with its  cells outlined in a thick border and positioned in front of a scaled screen grab of the original motif (arrange/ aspect ratio turned off)use command key to select a series of cells to be filled in with color, I chose to use black the cell borders can be edited as wished. Here borders were removed by selecting none, then, in turn, the outer border was highlighted in an easy to identify thicker red line

Below are more variation on borders and numbering for the start of the machine knitting repeat. Adding digits to the Numbers original repeat serves as a guide to appropriate size scaling in GIMP. One way to obtain the repeat size is to type digits in at least 2 cells at the desired location in any row or column. Select both cells, click on the yellow dot, and drag it to the last cell in the series here I went into autopilot: the repeat is isolated. The lengthen X 2 requirement can be achieved later in GIMP or as here via the table/ arrange/ size option in Numbers (wrong step for mosaic/ mazes)
I change the outer border to one point dotted to have a guide for a screengrab The captured image may then be imported into GIMP, image mode is changed to color indexed, B/W bitmap, and it is scaled to the appropriate size. The view grid, snap to grid options are in use.
I worked in 1800 magnification, created a new canvas 2 pixels wider than the original on the left, copied and pasted that image onto the new canvas. In the center illustration, RGB mode is once again in use. The added green pixels serve as guides for using rectangle select to capture each of the rows containing them in turn and then using invert value from the colors menu to reverse background and foreground within each of those rows.  The completed color separation is shown on the far right, with those 2 extra rows on its left side the last image needs to be once again converted to BW mode. The 2 extra rows of pixels on left are cropped off, the image is scaled to twice as long for use with the color changer, and the original 12X14 repeat is now 12X56
the actual BMP

this is the charted and tiled original repeat. There are classic differences from what is typically thought of as “floatless fair isle” in it. The very last row ie is in one color only.  When those 2 passes are made with the “no knit” color with the change knob set to KC I, the first and last needle will be selected. Push them back to B position prior to knitting the next row to avoid side to side floats.  Because of the maze component floats of as many as 7 stitches are created on the purl side in one of the 2 colors. A quick proof of concept swatch: this is a slip stitch fabric, note the difference in width between the patterned area vs the plain knit. If one has a ribber and the appeal lies simply in the lines created by both mazes and mosaics, those features can be retained with DBJ, and the fabric will lie flat. There will be limitations as to the thickness of the yarn used. a “pretend” longer repeat
The question has come up in forums as to whether the DBJ separation can be used for mosaics and mazes. The “Japanese” one, which prevents elongation by knitting each color for each row only once does not since these shapes rely on knitting the same needle selection twice in each color. The default separation in the Passap or the designer self-drawn one that will knit each identical spot in the motif separation twice. The design is elongated. Susanna wrote a technique for use on the E6000 for having the console perform the color conversion for true mosaic knitting. The repeat shown earlier in this post separated for DBJis compared here with the earlier wrong separation for “mosaic knitting” and found to appear identical. The process was a quicker way than that of dealing with different colors for ground and design
different pairs of colors, same results Back to the drawing board: row height is as in the original repeat being extra careful, not necessary, the process can be inverted once more to check the repeat color separation the actual knitting repeat, double-length before downloading to machine the corresponding proof of concept swatch,  with shorter floats than when the DBJ separation is used single bedtiling of the original repeat and its color reversed image illustrate the optical difference between switching dark and light color starts This repeat is from Kathleen Kinder’s (24 stitch) Floatless Fair-Isle book, p.86the repeat of the design separation on the right is intended for use in electronics with color reverse and double length chart separated using GIMP for mosaic knitting matches her repeat Recently on Facebook mazes turned up as a topic in machine knitting once more. Most maze generators online that I have found are designed for printing out game solving images ie here is one from http://hereandabove.com/maze/mazeorig.form.htmlfor knitting purposes unikatissima and Laura Kogler offer alternatives. Years have gone by since I first wrote on mazes and mosaics. The repeat worked with below was used in my post 

here I am revisiting the same image. To begin with, a repeat is isolated and processed in numbers (top row), and then in turn in Gimp. Always tile repeat to check for any errors and to see if the final image represents what is desired
the repeat (8X16) is then doubled in length for knitting after that single all-white row was edited out (middle images). The repeat is now 8 rows wide by 32 rows in height
One of the yarns is chenille, the other a wool. The chenille is slightly thicker and fuzzy, so some of the yellow rows are almost hidden but the pattern is definitely there. Here the design is knit using both slip (bottom) and tuck (top) settings. Again, there is a noticeable difference in width produced by each stitch type.Observations: make certain that after the image is isolated in Numbers cell size is converted to square/ equal measurements in width and height before importing and scaling its screen grab in GIMP if not already so. It will likely load in RGB mode, convert to Indexed before scaling. Added colored squares are only possible if you return to RGB mode. After rows with colored squares are cut, return the image to indexed before saving as BMP for knitting. If any pairs of rows do not have 2 consecutive rows of cells in either color check your pattern. In DBJ the final repeat should be 4 times in numbers of rows in height to the original one, and thus divisible by four.  The separation first doubles height for each row for 2 colors. Then height is doubled once more to allow for color changes every 2 rows. In Mosaics and Mazes, the color reversal happens on every other row in the original design. When that is completed, the height will be doubled for actual knitting to allow for color changes every 2 rows, with the final row count double that of the original motif. Rules for tuck knitting apply here as in any other technique. If white squares in the final chart have black ones on either side of them, the appearance is that tuck would be possible. Examining needle preselection is an easy way to assess that possibility.  Reversing the colors used in actual knitting may yield interesting changes in the appearance of the fabric.

Reversible DBJ, Brother knitting machines

I am including notes on my working through the process and some of my stumbles at the start of this post. More specific how tos are found toward the bottom of it.

Such fabrics may be created with both the KRC built in function, or with the color separations that knit each color for each design row for 2 consecutive, identical rows. Punchcard knitters are not excluded. The starting side is on the left for the KRC setting (B in this illustration), on the right side for the alternate color separation (C, double length or drawn with each row repeating X 2). I am still testing my 930, for my samples I began by using the built in pattern #16 in the Stitchworld Pattern Book I.In the absence of a jac40 the fabrics are knit by manually selecting stitches to upper working position (E on Brother) on the ribber bed every row. Preselection for the next row to be knit on the main bed makes the process far easier.

In my first sample, the colors are the same on each face. Since the same number of needles are selected for both design and ground, both sides of the fabric will be exactly alike. There will be floats, enclosed by knit stitches of the opposite color. Beds are set at half pitch. Consistency makes any process easier and more predictable. My ribber set up was also with an extra needle on the ribber at either end of those in work on the main bed. I found I had less issue with the long floats in my design when I made certain the needle selection began with needles to the left of those in work on the opposite bed rather than to the right, allowing for the color in use to knit first on the ribber, then in turn on the main bed. It may not matter with patterns with shorter spans worked between the 2 colors. The dropped stitch issues below were resolved by using different yarns, no other changes. 
The needle set up in colored squares and on my needle beds showing matching selections on both beds (different design rows). Some of the floats may be seen created by the blue yarn in the bottom photo. If first and last needle on each side were not selected on the main bed, the needles at each end on the ribber were added to hand selections for next row (blue squares)


better results with the different yarn choice

For DBJ that reverses ground and pattern colors, opposite needles are selected on each bed. Color 1 knits the design on one bed and the background on the other at the same time, while color 2 knits the reverse. There are no floats. I knit this fabric as well at half pitch. The ground color created pockets (white squares), with the pattern color (black squares) locking the layers of fabric together. Here again, first and last needles on the ribber were worked on each row. I began pushing needles up on the ribber beginning to the right of each needle in work on the main bed. Needle selection on ribber matches unselected needles on main bed (pink). All needle positions each bed are mirrored.

needles actually selected on both beds (pink), different design rowOne design row, 2 different angles

Since ribber fabrics are not visible for a large number of rows, I frequently scrap off after short distances to proof technique before committing to longer pieces as well as to asses whether the effort is worth it in order to produce the fabric in that particular technique or yarn.

Moving on to a self drawn pattern, the technique proved to be sound. On inspection however, I saw I was actually missing a pixel in the .bmp I downloaded, and on the reverse the green arrow is most likely operator error in needle selection. The orange dots highlight the missing pixel/contrast color stitch, and on the color changer side I had a really sloppy edge that needs sorting out (red dots). A possible added factor: I knit the motif using KCI, and later recalled end needle selection does not always work with the carriage I am using.Here I filled in the missing pixel, and drew a single pixel black line along each side, testing a “border”. The first and last needles on each side were now cast on and in work on the main bed.

That single stitch solid color line does not add to the design in my opinion, so back to the drawing board: side “border” pixels are eliminated. The first and last stitch are now in work on the ribber. This fabric is the best by far, at the very start I forgot to cancel end needle selection (KCI), then switched to canceling it, KCII on electronic.The how to in summary: first and last needle are on the ribber. On the electronic choose KRC for the built in color separation for the fabric to be worked in DBJ. KCII (no end needle selection). With free pass to right, both carriages set to slip <– –>, select for first row of knitting to be worked in color represented by white squares in the design chart. Both carriages remain set to slip in both directions throughout. On the ribber bed, bring up to E/hold position first needle on the right of any needle selected on the top bed, then continue to push needles up into work to match the number of not selected needles on the knit bed. As needles are arranged, there will be a space between the last hand selected needle on the ribber, and the next needle in work on the main bed Now that there is that extra needle in work on the ribber on the color changer side, to match selection as seen above, needles are hand selected to E beginning on the far left, still keeping that space just before the next needle selected by the pattern reader. Remaining selections began to right of needles on main bed as described above.when selection begins on the main bed on the leftGetting back to working the same pattern on both sides of the knit: first needle on the left is on the ribber, the one on the far right on the main bed. On the electronic select KRC for the fabric to be worked in DBJ. KCII. With free pass to right, both carriages set to slip <– –>, select for first row of knitting to be worked in color represented by white squares in the design chart. Both carriages remain set to slip in both directions throughout. On the ribber bed, bring up to E/hold position first needle on the left of any needle selected on the top bed, then continue to push needles up into work to match the number of selected needles on the knit bed. Small selection errors are seen on left image, ie on the second row on its right, may be easily repaired by duplicate stitching. The stitching yarn may be fed easily through layers of double knit for short distances before and after the “mistake”. With all settings and yarn being equal, there is a difference in size between this fabric (larger of the 2) and the one with color reverse on its other side 

A similar set up, working in full pitch. Here needles line up directly below each other. If wrong needle is selected it will be point to point with the needle immediately above it, and is an added clue the wrong needle is being pushed up into hold/ E position. My first swatch had distinctly different side / vertical edges. Cast on was for every needle, half pitch (top image), first needle on left on main bed, last needle on right on ribber. When completed, it was followed by change to full pitch prior to pattern knitting, lining up needles point to point, directly below each other (bottom image). I prefer the edge obtained on the half pitch throughout, seen in previous  sample 

Still pondering those edges, and what about repeats with large areas of solid color? The image on the left is 25X26 rows in height, the one on the right adjusted for an even number of solid color rows, and a total row repeat divisible by 4, 25X28. The single black line at the top is a marker for returning the carriage to all knit when the top of the repeat is reached. When using full pitch, solid areas remained open at both edges with carriage set to KCII. A wooden tool handle is actually inserted through from one side to the other in the bottom of the swatch. Because the needles are point to point, no extra needles could be brought to work on both ends as a work around. KCI will select end needles on main bed. I tried that as the first work around to seal the edges. I paid no attention to whether needles were selected at each end every row, and got another creative pair of edges.

Returning to half pitch I brought up to work the first needle on the left every row (too many rows at seen at R top edge compared to other side) and pushed the last needle on right up to work if it was not part of the group to be brought up to E.Analyzing the fabric structure in those areas of solid colors on alternating beds: at first full pitch makes sense if one has knit tubular stripes or solids which have closed edges, with the yarn making a single pass on each bed, traveling back to the color changer, with the option to stripe every X, even number of rows. Such stripes occur evenly spaced and identical on both fabric sides. Here the goal is to knit the fabric with large blocks of solid, alternate colors on each side. The main bed knits color 1 on selected needles on the top bed only, the alternate color is knit with the ribber needles being hand selected up to E while the main bed is slipping, with none of its needles selected. Other than that first set up row with preselection from the left, 2 rows are knit in color A, followed by 2 rows in color B. There are no stitches traveling between the beds to seal the fabric together in those areas, creating open sides, so if the goal is to have the edges seal. other steps need to be taken. A single pixel solid line along either edge of the repeat did not create a good edge. Full pitch is easier than half pitch to manage. One possible solution to both issues is to alter the side edges of the design repeat so there will be alternating needle selection along those side edges, thus sealing the fabric.

I decided to cast on with white, and to continue with white as the first color used in pattern (white squares in chart). This swatch was knit in full pitch. Edges are sealed throughout. The only hitch was when the top was reached and that all black squares row was reached. I was on the right at that point, with my dark color in the feeder. The row toward the left would have knit in the dark color instead of the white on the top bed. I cut the dark yarn, made a free pass to the left, continued in plain knit in white to right, and then transferred stitches and bound off. Top and bottom edges /borders in terms of number of rows, whether to add pattern there as well, are all subject to personal preferences and taste.

A complex published transfer lace to electronic repeat for download/ GIMP editing


Lace on the machine can render beautiful fabrics that closely resemble hand knitting, but programming very long repeats is a challenge both in placing every hole in the correct square in a punchcard and in programming individual pixels on a mylar or as pixels for download correctly. I found the “leaf lace” repeat below shared frequently on Pinterest and thought I would test the approach discussed in the post on using numbers and gimp to create images for electronic downloads. Because it is 16 stitches wide, it is not suitable for punchcard knitting, which requires a factor of (4, 6, 8, 12) and up to a 24 stitch maximum width.

The published pattern on the left is shown as shared on Pinterest. In turn, in was captured, opened in Gimp, and magnified. After a threshold adjustment, it was converted to a BW indexed, scaled to its 16X96 original stitch and row count, and then saved in 100% magnification result for the possible electronic download.

On far left below is the first BW processed single repeat isolated from its source. To its right it has been adjusted so the first row is a preselection row for the lace pattern, and the full repeat ends with blank rows (Brother KM characteristic). The latter in turn was saved as an image for download. Since the leaves change direction in the way they lean, the spacing between each pattern swing in the repeat is actually 3 all blank rows, not the “standard” 2, including at the top. The bottom half begins with the first row resulting in transfers to the left, while after the first 3 knit rows the transfers will begin to the right.  The plan was for me to use Ayab for knitting a proof of concept swatch.  In order to achieve that, the full repeat is first flipped horizontally (ayab will auto mirror it,  so starting with it this way it will be in the correct orientation when knitting). The mirrored repeat may be used in unaltered machines as is with LC operating from the right, KC operating from the left (not possible in ayab without adjustments). The full repeat consists of 16+14+18+16+14+18= 96 passes of the lace carriage, for every 12 rows knit. My sample was programmed horizontally for 3 full repeats, the width of my planned swatch. I added one additional needle in work on each side, with the LC end needle selection canceled, allowing for the full pattern as programmed with a single stitch all knit border on either side A tightly twisted cotton yarn did best in terms of handling the multiple transfers and not resulting in split stitches or breaking. I had occasional selection errors, seen in the center panel at the top of each repeat (my common experience with the interface), but the repeat itself appears to be sound.Lace repeats that have even numbers of rows for both and LC transfer and knit ones are easy to follow. Punchcards are also easily annotated and if knitting is interrupted needle selection is easy to return to or restore if necessary. In electronics, there may not be any memo to indicate row #  location for each carriage pass in pattern, or when to switch carriages. Because in this instance there are so many transfers (some of multiple stitches) between knit rows and dropped stitches are best corrected as noticed during knitting if possible, I created a “cheat sheet” of sorts to help keep track of actions. Each block outlined in red here represents one full repeat, read from their bottom-up, with blue borders at the center and red at the end of each half sequence. A visual check at the end of each segment’s # of rows in the series is well worth it to prevent unnoticed runaway dropped stitches and large holes. A check-in box next to # could indicate the completion of transfers. and a number added manually in that same row for that sequence, record the row on which knitting was interrupted ie. stopping on row 8 out of 16 to fix dropped stitches would be a reminder 8 more LC passes are required before the next visual check. 

9/23/18 In now have been experimenting on a 930, where each pass of the LC is actually tracked, akin to following numbers on a punchcard.  Built-in patterns also offer a memo window, which will alert the knitter as to when knit rows are due In testing the pattern with img2track I found the LC passes are still counted, but the memo window is absent upon download. I generated a chart in Mac Numbers, reads from the top-down, expanding on the one above. It illustrates the number of LC passes (left column) required to produce any significant length of fabric.  Patterns such as these are not for the faint of heart and require a friendly yarn. 2168 passes of the LC (33 full repeats, outlined in green; red line separates half repeats) are accompanied by 396 rows of “actual” knitting. In actual knitting, the pattern advances from row 1 to 96, and back to 1 again. A check-off list can be much simpler if one is desired. The numbers on left appear in the LC window in a 930, when reached 2 rows are knit with the KC. The numbers at the top reflect completed repeats. Boxes can be checked moving to the right as those rows are completed Another option is to download the pattern in img2track, and then enter memo information prior to knitting it. Two youtube videos that show how to enter memos in machine models that allow it, 930 included  https://www.youtube.com/watch?v=S0tXNT76v10    and  https://www.youtube.com/watch?v=nR8MheT5Bao. The number 2 may be entered after numbers on left appear in the LC passes count window, and provide an easy guideline to follow. And this is what testing lace patterns can look like. In this instance, a tighter stitch tension, a bit of change in weight, and visually checking after each row of transfers brought me some success. This is not a stitch pattern that lends itself to easy “repairs”. 

 

Pretend/ mock cables 3

A facebook group query brought up the possibility of creating cables in an “easier, quicker” way than by crossing stitches by hand. Over the years different authors have suggested a “sewn” method for pulling stocking stitch columns together in order to achieve the cabled effect. The illustrations are usually of the work done on a ribbed fabric, but it also may be achieved in simple stocking stitch, with ladders marking the edges of the mock cable, and providing a visual line to follow and count spaces when smocking the fabric up. The width of each column, the yarn fiber content, and personal preferences will determine the success” of the results.

I was reminded of “magic cables”, a technique made popular years ago in a copyrighted pattern series by Ricky Mundstock, ie this one from 1969 (illustrated online). The concept originated in a Japanese publication years before, relies on hooking up tuck loops to create the cable like effects.

I tend not to knit from published patterns, set out to understand what makes the fabric work in theory, and then sort out whether I have other preferences of my own for creating it. I began to experiment with a totally random tuck card. Tuck is chosen for the background because it is short and fat, giving the taller all knit rows for the “cables” the possibility of an additional gather, adding to their depth. I chose a purely random repeat, which is a good way to start for DIY if hesitant on the process. White squares will not be selected, will tuck for 2 rows, have a knit stitch (black dot in card) on each side of them. Max on Brother, unless using very thing yarn would be white bars single square in width, 4 rows in height (yes, there can be exceptions on rare occasions)

The card is cropped to the 24 X 44 stitch in width and height for the repeat to be worked in electronics. The area colored blue on the far right indicates possible all knit rows for hooking up “cables” during knitting, mustard color indicates ladders created by an out of work needle on each side of the central, all knit column. The ladders make it easier to identify each all knit column. The tape over holes idea does not work for masking a punchcard since that blue area would need to be all punched holes. The tape over would result in “unpunched” ones.

This takes the revised card single repeat and indicates some quick possibilities for altering itI added 2 more stitches to establish a slightly different pattern. The grab form my work in Numbers was then opened in gimp and scaled to 26X44 for the possible knitting pattern. If working with black and white squares, the image will need to be colored reverse for knitting. I abandoned this repeat for my final swatches in favor of keeping markers for hooking stitches up along the all knit column inside the ladders as opposed to the knit body of the remaining shapes.Here the non-selected needles are placed along the knit column itself, on alternating sides. The final repeat after correcting a pixel error I discovered while knitting:Ayab does not repeat across the horizontal row, each stitch in the width you are planning to knit needs to be programmed. For a test swatch, I decided to work with programmed 72 stitches (knit on fewer). This would be the downloadable file

magnified and gridded to visually check again prior to knitting itThis is what is seen by the knitter when the image is loaded,but any image loaded is automatically flipped/ mirrored horizontally by the software. Direction may not matter in the overall pattern, but here we have needles out of work, which if selected on the basis of what is seen as opposed to what is knit, would be in the wrong location. First preselection row is also only possible from left to right. The easiest way to empty the proper needles is to do transfers after that row, to either side, restoring needle selection prior to continuing to knit. Also, since there are needles out of work, end needle selection is canceled (KCII).

In my first swatch, I tried the idea of hooking up stitches in opposite directions, but was not pleased with the result, wanted to reduce the amount of hand manipulation involved. In the later swatch, I hooked up every other selection onto the same side. Arrows here indicate direction, not proper needle position.

Alternating side hooking up with some yarn and needle change issues.Hooking up to one side only was quicker to execute and appeared more pleasing to me. Both swatches had blips from an errant pixel.Steps in knitting the above fabric. The actual knitting will happen with what is shown as the repeat with white pixels on the dark ground, seen looking at the center vertical all knit column of the repeat when knitting the fabric. Allow the non-selected needle on the left side of the column to tuck, providing a marking row for picking up stitches, knit until the needle on the right side of the column is not selected. Prior to knitting across that row pick up the tucked loop and stitch on the left side
Lift both loops up onto the non selected needle on the right side of the column, bring that needle all the way out to hold (three yarn loops in hook)

Continue knitting until the next non-selected needle in the column appears once again on the right, pickup fromm below left marking spot and repeat. For DIY insert all knit columns on your chosen repeat, and proceed as above.
Visualizing possibilities: chart for side by side columns actions on purl side is shown. The black columns with arrows coupled with photos show the direction of the hook ups in the back, purl side of the fabric, and potential “cables” as seen on the knit side using the column repeat illustrated above.This is a garter stitch version found on Pinterest

Charting knits using Mac Numbers: color separations 2

This is not intended as a full tutorial, it presumes there is some familiarity with concepts for charting knits or proportioned graph paper using spreadsheets. I am sharing some of my recent explorations using the latest version of Numbers version 5.01 in Mac High Sierra 10.13+ OS. To my knowledge there are no other specific directions for using the program for this purpose. As I progressed through the separations below, I “found” new ways to deal with cell selections and table properties. At some point I will work on a expanding the original post on drawing motifs (Numbers 3.2.2).

The command key has become my new friend. In my past experience using excel I found limited ways to work with designing motifs and working with color in cell groups. When working on the design for 3 colors per row slip stitch for a segment of this post, I found holding down the command key while drawing makes clicking on cells and selecting them sequentially, to be akin to using a pencil/ paint bucket option in paint programs. The process is significantly faster than other steps I have tried. This image is the intended, final one Working on the table: the areas selected holding down the command key and in turn clicking on chosen cells sequentially are outlined. They were color filled with blue for my chart. The one extra square “error” in the center of the motif was dealt with individually, and changed in the subsequent color selection. For a screen grab with table markings, a cell must still be highlighted. If it is not, only the selected cell contents are captured. 

In a post I wrote in 2012 I referenced a splitting cells features which disappeared in later version of the software. These options for working with rows and columns are available. The highlighted row will be duplicated, one row at a time, a slower process than simply splitting cells. A positive feature is that an individual table may be changed while still within view of other tables on a single sheet, without globally affecting the document.It is possible to create blank rows between design ones. Though the results from such charting are not capable of being downloaded directly into knitting software, they are a good way to sort out repeats and begin understand and create any necessary color separations. By holding the command key, rows on the table can be be highlighted and hidden as a group. I chose all even numbered rows. The repeat then is drawn. When it is complete, rows originally targeted for hiding are “unhidden”, leaving the design motif with a blank row between each design row, at twice its length. Hiding could take place at irregular intervals as well.

Putting theories into practiceDOUBLE BED 

QUILTING: in terms of applying the technique, the first charts are based on a quilting post that created this example using other software

I had a 14 row motif in mind, so I created a table 28 rows in height, twice that of the motif. While holding down the command key I clicked on all odd numbered rows, and hid the 14 highlighted rows. I then drew the motif on the collapsed chart in the reduced number of rows. When it was completely filled in 2 colors, I used the option to unhide rows, having the expanded graph now 28 rows in height

On the left is the 2 color “basic” chart. You will notice it is missing a blank row at its top. Check to be sure that the expanded image has that space, it is needed for that last row of color 2 (blue) to move up. In the center, by clicking on each blue square and then clicking on it again and “dragging”, I moved each square immediately above its spot, on the matching location in the blank row. I like to work with black and white squares before drawing bitmaps or other formats for download, so the image on the far right has all colored squares reduced to black and white ones. I filled them in in Gimp using the paint bucket on a screen grab of the color separation, but it may also be done in Numbers (see below)

DOUBLE JACQUARD COLOR SEPARATION: this table was part of the review of color separation methods reviewed in a previous postFor the first method: testing using a simple shape, 8 stitches by 8 rows, create table 16 rows in height by 8 columns (stitches) in width. Hold command key, click on odd number rows, choose hide 8 rows from table menu, resulting in reduced 8 row height. After the motif is drawn on the reduced table size, the odd numbered rows are then unhidden. Next, fill in any squares in the restored rows that are empty in the row below, where markings already exist. This may be done all in one color, but I used green for the purpose of illustration. The image on the far right may then be entered into an imaging program ie GIMP for download, drawn as is. The choice follows as to whether to double it the file in height prior to programming the machine, or choosing software options for double height after loading it if that is a function of your knitting softwareThis image is from a previous post on DBJ separations for punchcard machines using the same size repeat and mirrored (punchcards reverse the image), offered as proof of conceptThe second method is for the color separation that knits each color for each row only once: the motif can be drawn in black and white. The sequence is different than for above. Rows are hidden in pairs above row 1 (16 in table left), then the repeat is drawn in black squares only. Adding a column with numbers for each row in the original provides added cues, and follow with the changes in tables. The rows are “unhidden”, resulting in the completed separation for color 1. Color 2 (in different colors in center chart for purposes of illustration): on first blank row, (odd row numbers for color 2) fill in squares empty in the row below, on the second blank row, fill in all squares empty in row above (even numbered rows for color 2). On the right is the repeat ready to be drawn for download. 

Drop stitch lace, one color, partial repeat inspired from post , 10 rows in height vs 9:  beginning with table 20 rows in height, repeat is drawn with hidden rows (markings on left), in addition design row numbers are added in a column on right expanded design revealing hidden rows, black squares ready to be programmed 

ONE REPEAT, 2 FABRICS once again, beginning with a repeat from a previous post DBJ with each design row knitting twice, no elongation: each design row needs to be expanded into 4 rows of knitting. The first table is drawn with table rows and design rows matching 

Starting at the top, using the option key and the down arrow, the chart is expanded by using the down arrow three times before moving onto the next row and repeating the command. Any errors in single rows are easily edited. I have added the green cells on the right to represent the alternate 2 rows of color 1, making it easier to keep an eye on rows as chart is edited further

holding down the command key, it is possible to perform the same action in multiple rows 

I began by eliminating the red on rows marked with green cells, leaving only the black in those rows. Copying and pasting the chart with each step provides a continuing visual check and may avoid restarts. In the center chart black has been eliminated from rows (with no color cells on far right) containing red. Lastly, red cells are changed to black for the final pattern repeat.

DROP STITCH LACE IN 2 COLORS: my original separation

Today’s much quicker method, using the all black chart from the DBJ separation for the repeat on the far right and the command key again, I selected odd numbered rows from the bottom up, and removed the fill. The results match the ones from the previous method 

Three color per row slip stitch: the method is the same as for 3 colors per row DBJ. The separation from my previous post

the repeat and its companion table:

6 rows are required to complete a single row of the design. These charts get very long. I chose to work first with each design row repeated twice, and then followed the same process as for the 2 color per row separation, including reducing the cells to all black. As one advances up the table, color markings on the far right indicate the single color that is to remain in that row. Hold down the command key, and select for removing fill in as many areas as comfortable. The magnified images with tables lining up side by side provide a visual check. For screen grabs such as these, the individual tables may be moved to front or back of others by using the arrange feature in the format menus. The black and white squares would be converted to punched holes in a card (as is) or pixels. On either machine, they require elongation X2 for use with the color changer. Again, the increase in length may be achieved prior to download in your paint program, or automatically in software or KM that has the feature built in. To elongate the image on the right use option and down arrow if starting from the top. I added design row numbers on the right of the table to help track the process. Clicking on those numbers performs the same action as doing so on row numbers generated by the software when creating the tables. At left is the repeat in process, on the right the final one. Note: the numbers 6 and 7 are sequential on the left, an error, with no empty cell vertically between them. It is easy to see which row is not elongated, and to make the correction seen in the image to the right. 

SINGLE BED

It helps to have some understanding of rules for creating fabrics such as mazes and mosaics prior to designing your own. The color separation can be a tedious one. I have previously worked out the repeats in paint programs. This method is far quicker, but there are still lots of pixels that need to be entered in software for download or squares that need to be punched. There are very interesting results that can happen by using pre punched factory supplied punchcards. Any of the same designs may be worked both single and double bed, but the topic here is for a diy approach to the separation for suitable designs

MOSAICS 2 WAYS: I previously posted on drawing motifs, and moving from design to pattern. Here again, I am starting with an 8 stitch repeat. The first method results in a repeat suitable for use with electronics. The repeat then in turn needs to have its colors inverted, and is programmed to knit double length. Color changes will occur every 2 rows. The original motif is on the left, shown with hidden rows on the right. The expanded table is 16 rows in height, double the row height of the original repeat (8). Hide odd numbered rows, and fill in your motif. (Note table row markings as opposed to design repeat row markings)
On the expanded graph, with unhidden rows, on odd numbered design repeat marked rows, fill in empty squares with another color. Follow that by in turn removing any black squares in that same row. Hide rows to collapse the shape, resulting in the top image on the far right. The bottom right chart repeat illustrates pixels that would need to be programmed. The setting is slip stitch on the main bed <– –>. With color reverse, the now white squares will knit, the now black squares will slip.

Punchcard knitters need to punch the majority of squares. That are manually  accomplishing the task automated by color reversing the repeat in electronics. This fabric is knit at double length, with color changes every 2 rows. The alternate color now fills in empty squares on even numbered design repeat marked rows in the expanded table. Black squares are removed from those same rows. Hide blank rows. Bottom right chart shows stitches that will be knitting, white squares will be slipping. 

EXPERIMENTING WITH LARGER DESIGNS I began with an image used in one of my earlier posts on topic, worked through the whole process and realized at the end of it that my repeat was technically 23, not 24 stitches wide, so it was back to the drawing board for the separation once again with the now counted and marked 24 stitch repeat. Tiling is a quick and easy process using gimp, and these repeats should be checked as those for any other type of fabric.

The newly corrected repeat (center) was then drawn onto a table twice its original height, as described above. The added rows that will be hidden and in turn unhidden are partially  shown in incomplete width and highlighted on the right. A second color may be added to the repeat at this stage, but I find the results too much to deal with visually for further editing The rows are hidden prior to drawing the repeat, and unhidden to create the expanded graphs. Command is held down while clicking on selected rows along the design height for both actions. I find the expanded rows easier to follow for editing, with the blank rows between giving my eyes a rest. If black is one of the colors, the borders may be drawn in any shade other than black to make counts in black areas easier. Some of the early programs actually assigned black as the value for the €œtransparent€ grid, automatically changing palette colors to other values, or resulting in error messages if black was part of the design palette.  Since eventually the repeat will need to be reduced to pixels or holes in cards, one can attempt to skip a step by using a darker color for color 2 in the separation and count squares and draw pixels from there. I personally find it easier if I am dealing with only black squares when plotting out pixels for download. Adding color to numbered table cells on the right is another clue to follow. Within the spreadsheet the whole document allows for easy travel between magnifications for easier editing or prepping for any screen grabs. 

Here the repeat is drawn, rows are unhidden, on even numbered design rows (highlighted on the right in green), the empty squares in that row are filled in with a different color (red). The black squares in those same rows are then in turn emptied of color (no fill). Again, holding down the command key while selecting across a row allows the same change to be applied to all those cells, making the process faster

a partial repeat for the squares altered in colors for respective color changesthe completed results for each stepIf rows are hidden at a this stage, the center image will result, and all red squares may be changed to black if preferred

As mentioned, I prefer to work on expanded graphs. When ready to hide rows, select empty squares (no numbers) on right, again holding down command key while doing so to make a global change as opposed to row by row 

The BW image tiled. Most electronics (ayab is an exception) require a single repeat in width and height. If color reverse is an option, one may program white squares and use the machine or software to color reverse. Punchcard knitters use the 24 stitch width repeat in width, twice in lenght, punching all black squares. Slip stitch <€” €”> is the default setting.

After all that, let us not forget that for color changes every 2 rows the new repeat needs to be programmed to knit at twice the height. Again, most electronics (ayab is an exception) have a double length option. I began at the top of the repeat, working my way down. The pull down table menu may be used, or the shortcut: option key, down arrow for an exercise in “add row below”. One can verify that no rows have been skipped by checking on design row numbers on right. Punchcard knitters punch black squares. Electronic knitters have the option of drawing and programming the white squares as well, but followed by color reverse option prior to knitting the fabric. 

In a later post, on using numbers and gimp to produce files downloadable for knitting on electronic machines, the method is explained for taking the numbers generated image above, opening it in gimp,  where stitch and row markings are cropped. The mode is then altered to a BW indexed one,

which scaled to 24X28 is ready for download (shown magnified here) 
and the repeat shown in a tiled configuration test 

Lace edgings on Brother machines

The initial goal here is to produce a knit fabric using lace transfers in the familiar way, but the knit carriage will now be set to slip <–>, selecting needles with each pass. In routine lace patterning the KC is set for plain knit, does not preselect needles, advance the mylar, punchcard, or other electronic patterning.

If this image, where all blue squares represent knit stitches and white squares unworked ones, was provided with the intent of its being produced as a piece of knit on the machine, the initial approach might be to use a single prong tool to move the edge of the blue in one stitch to the right for a decrease, and out one needle to the left for an increase. When the decrease is made on the bottom curve, the needle from which the stitch was taken is put back out of work. When an increase is made, a stitch is moved to work on left, and the last stitch on that side is transferred onto it. As knitting continues, that now empty needle location will create an eyelet.

I decided to wing it for the first swatches. This illustrates the same knit shape. Blue rows represent all knit rows and stitches, the empty pairs of rows leave areas to insert lace eyelets in pattern.

Arrows indicate the movement of the lace carriage on left, knit carriage on right. Red squares now represent transfers to right, green ones transfers to left

A second transfer to the right is included in the pattern close to the left edge of the trim to create eyelets next to the decreases, matching those eyelets created by stitches moving out in the increase segment of the chart

A theoretical series of right and left transfers is then inserted, creating a shape in the center of the trim’s width

Now reducing it all to black and white squares or pixels for first preselection from right hand side using an electronic. This repeat is not suitable for use in a punchcard machine even though it is 24 stitches wide. Electronics advance a design row with each pass of the carriage when cam buttons are pushed in and with both carriages set to needle select. Punchcard machines in those circumstances do not advance when the alternate carriage is brought into work from the opposite side. This charted repeat is usable as is on an unaltered 910, with the first preselection row from right to left. LC operates from the left, KC from the right.

For use with Ayab software two other things need consideration. Ayab mirrors lace repeats, so either mirror the repeat of the original design, or choose action mirror in the software prior to knitting. This is a screen grab of the repeat used for my initial swatch test. I later changed the section where the diamonds cross in at the center of the eyelet repeats In addition: those first 2 rows need to be all knit, so the top row of the design was moved down to row 1 position.
KC preselects left to right, knits black squares to left, preselects same needle selection again to knit those same stitches traveling back to its home on the right, creating the two knit rows that in “normal lace” would be worked with the KC simply set to knit.  As the KC now knits the second row, it preselects needles for the first row of transfers, rests on the right
LC transfers to right as it travels to left, preselects the next row of transfers. As it moves back to left it transfers to left, preselects for first of 2 all knit rows, rests on left
The sequence is repeated  until the piece reaches the required length.
End needle selection is off on both carriages. As LC travels to left, because of no end needle selection, the first needle on the right is not selected. An option is to manually pull that needle out to insure it knits. I decided I actually preferred the chain created by those single stitches knitting only every other row, but was not happy with the elongated stitches on alternate rows edge stitches on the increase side. These would be the carriage actions To review: end needle selection is off on both carriages. As LC travels to left, because of no end needle selection, the first needle on the right is not selected. An option is to manually pull that needle out to insure it knits. I decided I actually preferred the chain created by those single stitches knitting only every other row. I had a serious yarn tangle on the right about halfway up the swatch, with some of the evidence visible in the approximate center of the swatch photo 

changing that crossing of the diamond outlines, still winging it

My fiber is now a crisp cotton, unmarked weight, tension 8, and it is much easier to observe areas that may still be a problem to me as the designer. Ideally I would prefer the lines created by the transfers marked in cyan to match the quality of those immediately below or to the ascending part of the diamond on their opposite side, that would require changes in the transfers sequences and space between knit rows. The LC non selected stitches on the straight creating an every other row slipped stitch are still something I like.  The difference on the edge stitches in the ascending angle are happening because with each transfer out, there is a single thickness of yarn on the new edge stitch and moving the stitch over a needles space elongates it. Longer loops btw are also created when single increases are made by bringing needles into work on the carriage side prior to knitting a row across all needles. In the trim’s decrease edges, the transfers in each new edge stitch have double the yarn thickness contributing to a different appearance, highlighted with magenta arrows. There are 2 rows that have no edge transfers programmed intentionally in the center before reversing direction, so that area has no resulting edge eyelet.  The last shot at adjusting the repeat, with improvement in those cyan marked areas. Plain knit rows may be added between each repeat, the edge of the knit will be different than in the remaining trim on each side

Going back to the wheel that has already been invented, how can pre drawn published mk lace repeats be used instead of “winging it” endlessly or not having the confidence to perform the necessary assigning symbols and proceeding with the required separation? Still trying to work with a pattern that knits for 2 rows, transfers for 2, a chart from Stitch World:marking the 2 all knit rows that will be plain knit by programming black squares The pattern is actually for an all over lace. All the transfers in the central diamond actually are happening in the same direction. If the repeat was programmed in the usual manner, beginning with LC on the left, those transfers on the first design row and in the whole of the center diamond shape would all be to the left. I can live with them all being to the right, and would be interested in more eyelets at the edge of the trim. Here is a new repeat, with the increased eyelets at the curved edge Remember if using ayab to mirror the above repeat (seen on right) prior to preparing to knit it There is a disruption for 2 rows in the very center of the diamond, where no increases or decreases occur on the shaped edge prior to reversing the shaping. It was there in the earlier sample marked with arrows as well, but not as noticeable where the edge was created with the addition of single eyelets on increase and decrease rows.

Not finding any other candidates to alter for this purpose in stitch world at the moment I am left with the option of going back to the Brother punchcard book collections, and reviewing what needs to be changed for those same patterns that work so well with the KC set to plain knit but are now to be knit with the KC set to slip <—–>……

3/7/18

a lace punchcard repeat with transfers in opposite directions Assigning colors to transfers: red to left, blue to right. In theory the same repeat could be used flipped horizontally for operating the lace carriage from the right. Yellow lines highlight the 2 blank rows in card that will be replaced by black squares/ pixels (remember rules are different for slip and lace in punchcard knitting)Since the goal is a trim, things are rearranged for knitting to begin on the full 24 stitches There are 2 ways to get the above repeat to work, one is by adding extra blank rows. I chose to reverse positions for transfers, moving left transfers upon row, and red down one row. With lace carriage operating from the left this is my new repeat, with edge shaping added for trim edgeKC is set to slip after the first preselection row, first set of transfers is selected on its second pass to the right. The first transfers with the LC are made to the right, the second set to the left. If knitting the repeat using Ayab remember the above is mirrored by the software, so choose action mirror prior to configuring

I knit a swatch using the thinner yarn again. The difference in increasing angle can be seen here as well, the pattern is short, so the outer curve of the trim reflects that 

This would be my test repeat for knitting the same trim in ayab with the LC operating from the right. The software would mirror it, no action needed. The last row is shifted to the bottom to allow for the knit carriage finding a home on the left. First row knit would preselect 2 needles only, with KC then set to slip in both directions, the next two rows should knit, preselecting the first row of transfers to be made by the LC operating from the right.

I am unable to test the repeat. I have had intermittent problems with patterning in the sofware from the time I installed the kit. In multiple efforts and restarts I am now getting no selection at all or wrong selection with LC operating from right, while rows advance in the software and beeps continue. I have knit lace with the LC on the right before, but not with the KC selecting needles as well. Possible solutions and causes to be determined. 3/8/18 I have been told upon testing by others the same issues have been encountered that I did when using the KC to select from left and the LC from right, and the problem appears to be the result of a bug in the software to be addressed in future updates.

3/10/18: an adaptation of Susanna’s automatically shaped trim for Brother KM, p. 223 of “A Machine Knitter’s Guide to Creating Fabrics”. This chart shows the first rows of the published punchcard. Please note: using my own lace carriage, when I tested canceling end needle selection, the problem was not solved. Brother setting recommendations made for a similar transfer pattern in an edging published by them, are given and repeat is pictured at end of my post.


Row 1: LC moves to right, no needles selected
Row 2: LC moves to left, preselects next row of transfers
Row 3: LC moves to right, transfers preselected needles to right (red dots), selects needles (if any) for next pass to left
Row 4: LC travels to and transfers to left (green dots), preselects for first row to be knit by KC In this particular pattern the direction of the arrows match the direction of the transfers with movements of LC operating from left
Row 5: KC from right, set to slip <€”  €”> knits all needles in D position, repeats the same selection as it travels to left (yellow marks)
Row 6: KC travels back to right, in the second shaped knit row, preselects for the next transfers to be made by the LC
Row 7: LC travels to and transfers to right, preselects for next row of transfers
Row 8: LC travels to left, transferring to left if any needles have been preselected on the previous pass, and the process continues

The numbers on the punchcard chart do not reflect actual row numbers in knitting because when row 4, 10, etc is reached, on the next pass (a blank row in the card), the card does not advance and the previous selection is repeated. For each carriage to make an even number of passes to travel to and from its original position, the total length of the repeat must be an even number of rows.

Here are the 24 stitch repeats adjusted for knitting on the electronic. A for an unaltered 910, B indicating direction of transfers (red to right, green to left). Arrows mark the problem row, and my solution to it C on the far right, along with the repeat adjusted for use with Ayab.the ayab screen image for working the edging  Both KC and LC are set not to select first and last needles in my directions. When the decreases start to happen on the left of the chart, because the end needle selection for transfer to right again does not happen in areas marked with magenta arrows,  there is an extra stitch that remains on the left that does not get transferred (orange dot) so it is not knit off and simply get held as subsequent rows of knitting take place. Restoring needle selection in the LC is not a solution for the problem, so the final repeat has been amended by me to get that edge transfer. The pattern starts on  cast on 20, not the full 24 stitches. Ayab knitters: use the LC to begin selection from left. The first pass will select for a knit row, push those needles back to B, and the LC will select for transfers to right on the next row as it moves to the left. When knitting is to take place there is a clear distinction in the number of selected needles (black squares). The KC will be set to slip <–  –>. Make certain to remember to return the remaining 4 of the 24 total stitches back to B so the full repeat is in work on the needle bed before continuing in pattern, otherwise there will be needles there to accept stitches moved over for increases to left.

The two extra passes of the LC in this method result in a 2 stitch border on the increasing and decreasing angles of the piece, creating a much nicer edge than that in the samples at the top of the post. The eyelet so close to the right edge stitch which also winds up being slipped every other row made for very messy loose stitches in the thicker cotton that I could not control. The sample did better when I pulled the non selected needles on knit rows out to hold prior to moving across them with KC. 

When working on electronics the 24 stitch limit in width for the repeat is no longer there, extra knit stitches may be easily added to the right of the pairs of eyelets along the non shaped edge. Having those extra stitches knit on the right side of the repeat made it possible for me to use my cotton again, giving me a controllable edge on that side without having to pull stitches out to make them knit. To my eye, I find the extra passes with the LC and those extra knit stitches on the right are well worth the effort and planning in the finished piece

the ayab repeat  

Something to try: I found instructions ascribed to Brother
for another version of an edging using a pattern that has the same eyelet sequences along the shaped edgings. Their recommendation for a 950i is to remove the non selection mechanism on the lace carriage, and mention was made of the “rubber wheels on the carriage” being uppermost, allowing the end needles to be selected. My lace carriage has fixed, old fashioned brushes, not rubber wheels, and my eliminating end needle selection did not solve the problem with that single stitch in the center of the repeat. And if there is not enough to keep track of, this also combines fine lace and traditional transfer lace, would work fine as just lace.

3/15/18 after more testing I have come to the conclusion that end needle selection cancellation on my 910 LC is working properly, but is not operative when I am working with the my Ayab interface.

Double jacquard using punchcard machines

Each row of double jacquard consists of at least 2 rows of slip stitch patterning, one with ground yarn, the other with contrast. The rows knit per each design row varies with the number of colors used in the design. Punchcard knitters are not excluded from producing such fabrics, but the color separation is done by hand or using software, and then the cards are punched. Size of repeat is less important in creating interesting knits than choice of yarns, colors, and technique choices. In early art to wear days, pre electronic home knitting machines, large, non repetitive images were created by breaking down the large images into several vertical panels the width of the punchcard repeat plus seaming allowance. Upon completion, they were joined side by side to create the final image. Ribber settings for DBJ apply across models in principle, may need adjustment depending on the age and brand of the machine. If working on a bulky machine, consider using ladder back method.

The common method suggested in instruction manuals for Japanese knitting machines can be viewed in this punch card, laid over a colored template. The limit in repeat width is the fixed 24 stitch. To fit the design on a single 60 row factory punchcard, the maximum is 30 rows in motif height, because one row of pattern requires 2 rows of punching in the card. The step by step separation follows.

Helpful tools: on one blank card color each section of the card, representing color row sequences. This may be used later to check color separation. Box the edge numbers in pairs, beginning with numbers 56, 57, skip two rows to numbers 60, 1, and so on. This separation splits the first and second row of color 1 between the first and last row on the punchcard.

On a second blank card, prepare a master. First row is left blank, then 2 rows are punched out, followed by 2 rows left blank, repeat, ending with a blank row. Again working upward, number each row you have punched out on the left hand side starting with number 54, then 55-56, 57-58 etc, ending with a single row, 23. This will result in number markings matching both sides at the bottom of the card, below the #1 factory mark. My own master began on the left with the # 53. I also added corresponding design row numbers for each row on the far left. (1 and 2, 3 and 4, and so on). Written notes on right: an even number of rows need to be knit in each color, so in this method  pattern must be an even number of rows in height, boxed numbers represent rows knit in ground color.

Take a blank card and put the master card on top, fastening the 2 cards together with snaps.You can now mark holes to be punched. Copy the first 2 rows of color 2 on rows marked 54 and 55 (or 53 and 54 in my case), repeat in pairs for the required height. I like to mark the card to be punched with colored pencils that differ sharply for each color. They have the benefit of being erasable, and can help with keeping each row distinct when punching.

When the completed repeat is marked, unfasten the snaps and move the card down by one row. You will now see that the marks you have made through the top row of each set on the master card. Mark through each lower row any blank squares in the row above.

Again, after completing the repeat unfasten the snaps and slide the master up by 2 rows.The card will now be back to its original position, and up by one row. Now you will see the marks you have made on the blank card showing through the bottom of each row of the master card. Mark through each upper row on any square opposite the ones marked in the row below. 

After the repeat is completed, make certain to punch across 2 final rows for the card to create the overlaps for a continuous pattern, as with any other stitch type. Punch out all marks, and you are ready to knit. To check your design visually lay the finished card over the colored master, correct any errors if noted. Your card is now ready to knit DBJ.

First preselection row is right to left with color 1, it will knit from right to left, moving toward the color changer where colors are then changed every 2 rows. This color separation will not work for fabrics that require the same needles knitting for 2 rows.

A second master that may be used with the same approach, for a different type of color separation: 

This separation works with any number of rows repeats. The design will be elongated because each design row knits twice in each color, with 4 rows completing it. Fabric will be thicker as well, so use thinner yarns when working it. Draw shapes in colors that are chosen for clear contrast, not because they are to be used in the finished piece. Here I am back to those triangles used in earlier posts. The choice of which color you begin with, whether in the separation or in the knit is ultimately up to you.

With the masked card, the first row is marked on the very bottom of your new design, I began with the red, which would produce the equivalent of this

Remove the mask. Beginning with the second row from the bottom, mark in contrast any square not colored in the row below Punch all colored squares and you are ready to knit. I prefer to not rely on built in elongation if I am making a garment or a long piece of knit. If errors are made or correction of dropped stitches, loops, wrong color selection, etc. is required, unraveling rows is complicated enough without having to also sort out exactly where you need to be in relationship to where the card did or did not advance. Black squares represent punched holes, a segment one separated by the red line in repeat width could be used on a mylar or for electronic download

Another master for the elongated design, advancing every row, numbers represent rows being filled in, beginning with odd in this orientation, and even with the card rotated for marking even # rows in color 2

This is the same repeat, color separated and elongated X 2; proceed as with the directions above, but in this instance each row in each color is marked twice. The expanded repeat:

I have used these images to illustrate color separations in far older posts.

The reason the resulting separation here looks so different from the one above is simply that in this latest series of charts the color selections have essentially been inverted. The inversion creates a mirror mirrored back to the original orientation with the inverted colors in place, and the color reverse is now recognizable

As a matter of course it is helpful to be consistent in choice of starting color when separating motifs. Any single repeats isolated from above are usable in electronic machines, reduced to black and white squares. Electronics vary in the built separations in terms of choosing black or white squares for the first row knit, whether you download an original image or work with built in ones. With preselection of needles in Brother or pushers in Passap, with an easy to count color repeat and some air knitting, planning starting color of choice and needle placement can be sorted out for more confidence when actual knitting starts.

If you would prefer to work on graph paper that matches the size of your punchcard, there are a downloadable PDF and word doc with some guidelines in my previous posts more-low-tech/ and creating knit graph paper. The posts were in 2011 and 2014, with illustrations drafted in earlier versions of OS and apps. Working in Pages I was now able print an image just about to perfect scale to part of a blank factory card. Here is part of the first repeat in this post traced through the punchcard holes onto it:

I then exported 2 documents, one to Word, the other to PDF. The first printed image and the PDF one (opened in Preview) printed to identical scale using my Epson Printer. Here are the new docs for you to try, they may need tweaking. My measurements, adjusted in Pages were 11 cm by 18.2, for 30 rows in card height: PDF no numbers card, Word doc exported from Pages no numbers card . I have found squares of the blank card BMP provided may be filled in in either GIMP or Paint, using the paint bucket tool, but printed size is not in scale to the printout of the original in the pdf.

If scale does not matter and you prefer convenience, this is a numbered “full” punchcard template as PDF scaled to fit on a single page punchcard numbered, and as an editable Excel document exported from Mac Numbers: punchcard templates_ excel

Quilting using Ayab software


My last post reviewing the quilting on the machine topic so far. Ayab does not allow for the first pre selection row to be made from right to left. In any fabric where preselection needs to occur from that direction, with pattern instructions written with that requirement, in order to match the fabric the solution lies in shifting the last row of the repeat down to the first. If you are working on an odd number of needles and set up matters, pay attention as to whether the program places the extra needle on the right or the left of 0 before you commit to placement on your needle bed, the software is not consistent in this. Here the odd # is placed on Left, in a later swatch on the right. From Adrienne Hunter the tip “I think you are expecting that the odd number will always be on the left. But that’s not it, the rule is that the larger number will be on the left, which may be even or odd.

Ayab settings: 
I began with this partial repeat from an older post

To avoid any confusion with which KC (Knit Carriage) slip buttons to push, simply push in both. The selected needles that should knit in slip stitch will knit, and the ones that should slip (not selected) will slip. Knitting starts COL, prep the interface, travel to right. With COR proceed to left. Machine can be set to knit those first 2 rows, or to slip both beds if you do not wish to have the extra 2 knit rows. Now with COL set main bed to slip <–  –>, ribber to slip <–

My first repeat for a “square” pocket was wrong. The total number of rows in height needs to be an even one. It takes 2 passes of the carriages to complete one circular row. The first repeat below is 17 rows high; so I got as far as one series of pockets followed by mis patterning that was the fault of the design, not the program. The software gives one the opportunity to easily check for stitch and row counts. Though I loaded images 60 stitches in width, my samples are knit 40 stitches widethe amended repeat, now 16 rows in height 

I had a problem when I first paused to stuff pockets with the software advancing a row even though I was outside the left mark, but no issues after I restarted the process and continued. Because the pockets are knitting stitches separately on each bed except for where shapes are joined, the resulting knit approaches stocking stitch qualities and tension settings. It lacks the stretch of every needle rib, where twice as many needles are in work. The joins on the knit side (L) nearly disappear unless fabric is stretched, while joins on the purl side (R) are more visible. 

A “diamond” 12 stitch repeat as it would appear across the bottom of a punch card with the option for first preselection from either side, followed by appropriate cam settingsThe repeat adjusted for preselection from left, illustrating row shift on right
The repeat adjusted for knitting across an Ayab 60 stitch swatchThe bottom of swatch, with absent pockets, shows what happens if wrong slip/knit combinations are in use. Knit side is shown on left, purl side on right, with a bit of cotton ball “stuffing” poking through  
While trying to work with the circular and other settings I found an easier way to achieve one color quilting, still working with that “diamond” from my early post 

I use GIMP to create most of my images for download to either the Passap or now also the 910. In order for the elongation not to be muddy with an image outline in multiple colors, or to cleanly tile it, the image will need to be converted. To draw or paint, begin in RBG mode, then change image to BW palette for scaling or tiling 
make certain the number you wish to remain constant is highlighted
click on “chain” to break aspect ratio
change the second value to desired one click on scale, here is the single repeat, without the necessary last row shiftto tile the image across the width of your swatch make certain the value you want to remain constant is highlighted 
“break the chain”change width to stitch count of your swatch

the tiled image will appear in a different part of your screen, it will be the repeat usable for the first preselect row from right to left. More on using GIMP.

For use with ayab with a repeat that is already tiled but needs “correction”, using snap to grid, dot to dot, copy and paste all but last row onto a new image at the top of a new canvas with the same pixel width and height. Then copy and paste the last row from the above tiling to the first, blank row of the new image. You may also simply work on the original image if you are comfortable with moving the larger cropped image around, pasting it in place at the top, and then editing the first row by hand.  Finish with “export as” in your preferred format for download The smaller diamond would also be workable, but resulting shapes would be very small. The initial, unaltered tiling:for use with Ayab:
Ayab setting is for “single machine type”. The carriage settings: opposite part buttons, right on KC, left on ribber, are set after the first 2 preselection passes, with COL

the resulting elongated diamond fabric, knit and purl sides respectively

Thickening the outlines of the “diamond” varies the joined outlines; solid geometric  shapes may also be created and used as seen in other posts. I like to work with same or similar shapes to understand what the different settings do to their knit structure and scale

Working in more than one color: using the color separated repeat double height. The first chart below illustrates it as it would appear on the bottom of a punchcard. Here first preselection row would need to happen moving from right to left, toward the color changer, with subsequent color changes every 2 rows  
adjusted repeat/ top row shift to bottom for use with Ayab’s preselection from left This fabric requires changing ribber settings manually every 2 rows, thus creating a solid color back. Set the ribber to slip /levers up when most needles are selected on the top bed, set ribber to knit / levers down  in both directions when a few needles are selected on the top bed. The latter selection forms the “stitching” lines on “quilt”. The first color to knit after preselection toward the color changer knits the black squares on rows 2 and 3 in the chart above, so it will create the dominant color in front of the fabric, the second color change will knit the background / white squares on rows 4 and 5 above, and seal the edges of the diamond / black squares 
Reminders: no matter what stitch type, if you forget to select proper cam buttons after N/N settings you will only get plain knitting (stripes at bottom of my swatch). If you are working on a Mac make certain to set your energy saving preferences to insure it stays “awake” for the duration of your knitting time. I happened to knit my samples with cam button set to KC II. KC I is the better setting, giving a slightly different seal along the edge away from the color changer. 

What of using the ayab circular setting and letting the software do some of the “work” for you? The setting was developed for tubular fair isle, so the main bed  with slip stitch <–  –>  knits alternating colors. When the one color knits on the main bed, it skips and forms floats in front of needles not selected for that color. The process is repeated with each color change. There will be a pair of  floats on the inside of the knit for each completed design row. For some how-tos to achieve color separations involved, and more info on tubular knits including Passap techniques please see previous post

The goal is to had been to use the ayab circular setting to produce quilted fabrics, joined at intervals rather than as an open tube with a different pattern on each €œside€.  When attempting to utilize anything “off label” for a use other than intended, lots of trial and error can be involved. Ultimately the choice needs to be made as to whether the final technique is worth using simply because you can. I habitually double check my settings and fabrics at least once, a day or more after I knit my samples and post. The work in progress posts actually show some of the editing as it happens, with corrections and mistakes included. The heading goes away when I think I am done with the topic. A day after my pink and white adventure I tried to reproduce the fabric with absolutely no success. This was as close as I got, with different carriage cam settings, the knit side is shown. 

After quite some time and a collection of expletives in 2 languages it appears the solution to my inability to produce the fabric is because the ayab setting I used for knitting it was not the circular one. After a software patterning error and a program restart, I apparently selected ribber rather than circular machine type and proceeded happily to success. To produce the fabric in my re do: the ribber “machine type” setting was chosen 

the green yarn is thinner than the pink, so the bleed through of the white on the reverse side is greater. The remaining information applies. My first samples using a single stitch outline, length X 2 for the €œdiamond€ were a disaster in terms of stitches falling off, the fabric being a squishy, shortened mess.

Back to the drawing board: I thickened up the outline of the shapes, grading up and down in 2 rows in height sequences, needed for getting to and from the color changerI chose to continue to test on a narrower repeat. An added consideration: in knitting fair isle, the first and last needle on each side is normally selected whether by using change knob on KC I in 910, or adjusting knit under carriage in punchcard machines. One can program black squares on either side of the full pattern repeat for the width of the fabric to insure that any number of edge stitches knit every row on each side. Working on a smaller repeat, now 47 X 24note: the odd # and even number needle positions for this new repeat are in reverse order from the one at the top of this post. Here the odd # is placed to the right of 0, not the left
If for any reason you choose to work in color reverse, the black border on each side will be lost.The amended repeat to keep that knit border (black squares/ pixels filled in; this was my working repeat It takes a few tries to sort out what may work. These were my first effort switching ribber settings around until I reached  creating pockets.The color choice needs to be made re solid color for backing and sealed areas of the fabric; for me it was the pink. This is where things get a little fiddly. The fabric settings once the first design row is preselected: KC is set to slip in both directions throughout (remember to change main bed to slip if preselection row have been with KC set to knit). I began with pink for my “sealing” stitches/ solid backing color.

After return to left, change color (white),  no stitches are knit on the ribber, only on main bed

here the floats become increasingly apparent the ribber  now dropped a notch on the right side 
stuffing pockets with cotton balls the ribber is returned to up position, knitting continues 

A: setting operator error creating solid color row. B: same, ribber not set to slip in both directions, resulting in white joining all selected needle. C: stuffed pockets, tending to make fabric wider and shorter   A, B: extra sealing rows (2 in white). C: stuffed pockets and a bit of peek through cotton. D: points to bleed through backing color of white floats on the inside of the pocketsA helpful tune: pink down, white up in reference to right ribber slip lever.

The question now follows: which color separation does Ayab perform automatically for DBJ?
