Drop stitch lace using Ayab software 2/ HoP

At the start of 2018, I wrote a long post on creating drop stitch lace using ayab software and some of the techniques required to produce the fabric. Since then the software has been updated including several new features and among them the heart of pluto HoP color separation for executing multiple colors per row dbj, and revisited the topic providing links to all the previous related posts.  It occurred to me I might be able to use it to make drop stitch lace without having to manually perform the color separation and then entering it as a single bed pattern. This was my first proof of concept effort, dropping each of the 2 colors in turn. Making things work: my first desired repeat was what I expected would produce a circular shape, it measured 33 stitches by 23 rows.Increments in height need to happen at sequences of 2 rows each, so the design was then doubled in height, resulting in a scaled image now 33 stitches by 46 rows in height, with a planned horizontal repeat X2 = 66. Note: the sidebar offers start and end needles are given for pattern placement on the needle bed. Sampling may occur on fewer stitches than that. Since the number of repeats programmed add up to an even number and center alignment is chosen, the number of needles is even on each side of 0.In my second series of swatches, I decided to try for a smaller “circular” shape, with the repeat now measuring 15 wide by 20 high, and a planned horizontal repeat X3 = 45. If centered, the software places the odd number of needles on the right-hand side of 0.As with any pattern using Ayab, the starting side is with COL. The critical difference is that all needles are in work on the ribber, all needles on the main bed start in work but empty. White squares select first. The main bed is set to slip both ways throughout, the ribber for this fabric is set to knit every needle, every row. The choice then needs to be made as to whether both colors or only one is to be dropped. The software does the work involved in the separation, but the knitter needs to manually cancel needle preselection on the main bed on a regular basis as well as drop stitches formed there. This is best achieved by using a ribber cast on comb or a similar tool. A modified stitch dropping tool does not work unless all needles in work are in B position, so if they are pushed back it will work here as well but I found the cast on comb made the process faster. I will refer to colors as black and white, as they would appear in the design in black and white pixels. Begin with base rows in white. Whether dropping one or both colors, the first preselected row is disregarded on the main bed in both fabrics.
Begin COL: main bed set to slip <– –> (remains there throughout). As the carriage moves to the right, the first row of white pixels is preselected, the ribber only knits.
COR: for both fabrics, use the chosen tool to push preselected needles back to B position. As you move to left side and the color changer, the needles for the first row of stitches to be dropped in the next color (black pixels) will be preselected
For dropping both colors 
*COL: pick up the color to be used for black squares, loops will be formed on the main bed as you knit one row to the right
COR: push all needles forward so stitches on the main bed move behind the latches, I tend to do so all the way to E. As needles are returned to B position the loops formed on the previous pass will drop, creating long stitches on the ribber bed. As you return to the left nothing happens on the main bed (needles in B position are not worked in slip stitch), but the next row of white pixels will preselect
COL: pick up the color to be used for white squares, loops will be picked up on the main bed as you knit one row to the right
COR: push all needles forward to drop stitches on the main be, push all needles back to B, knit one row to the left side, as you do so next row of black pixels will preselect**
COL: repeat * to**
I knit until the green yarn broke for some unknown reason For dropping only one color of the two, I chose color 2, “black squares”after preselection starting row
COL: main bed set to slip <– –>. As the carriage moves to the right, the first row of white pixels is preselected, the ribber only knits.
COR: use the chosen tool to push preselected needles back to B position. As you move to left side and the color changer, the needles for the first row of stitches to be dropped in the next color (black pixels) will be preselected
*COL: pick up the color to be used for black pixels, loops will be picked up on the main bed as you knit one row to the right
COR: push all needles forward to drop stitches on the main bed, and then push all needles back to B. Knit one row to the left side, as you do so next row of black pixels will preselect
COL: now working with “white”. No loops are wanted on the main bed, so the last preselected row of needles needs to be pushed back to B before returning to the right, knit one row
COR: cancel needle selection again, as you return to left the next row of black squares will preselect**
COL: change colors, repeating * to **End with some rows on the ribber in “white” to match the number used at the start of the piece.
Casting on and binding off both need to be loose since the fabric stretches considerably when off the machine.  I like to start in waste yarn, make certain my colors change properly, pull down a long yarn end, and begin the final piece on open stitches. At the top, I bind off on the main bed, either transferring stitches up to the main bed from the ribber or taking them off on waste and rehanging them there. A latch tool bind off may then be done around two gate pegs or even more to provide stretch at the top. The bottom of the piece can then be rehung and the same bind off can be executed so the top and bottom edges will match in stretch and width.

Sometimes things are not necessarily worth doing because you can. I was curious as to whether an all one color drop stitch could also be executed using this separation. It is but involves pushing needles back to B multiple times in each sequence. I started with a shape, scaled it twice as long, erased every other row, tiled it X3 horizontally,The wider horizontal band of all knit stitches was due to operator error, happened when I pushed back preselection an extra time, resulting in the ribber only knitting extra rows. For the sake of added clarity, I have added color to the chart below, assigning yellow and grey to all-white design areas in the pattern. The black squares are what I choose to drop. For illustration purposes, this is only a segment of the repeat.The process: begin with COL: main bed set to slip <– –>. As the carriage moves to the right, the first row of white squares/ pixels (yellow) is preselected, the ribber only knits.
*COR: cancel any needle preselection for white (yellow) squares, all needles are pushed back to Bas the carriages move to the left, the black squares will preselect COL: knit to the right in order to form loops on the main bed,  they will be dropped to form long stitches
COR: loops have been formeddrop the loops, return needles to B position. At this point, since all needles are in B a modified stitch ditcher may be used for 2 passes, dropping the loops on the first pass and returning the whole series back to B on the second.As you move back to the left, all the needles will be preselected for the all-white row (grey squares),COL: push all preselected needles back to B, as you knit back to the right the next group of white squares (yellow) in the next design row will be preselected*COR: push selected needles back to B as you move toward the left the next row of black squares will be preselected selectedCOL: knit to the right in order to form loops on the main bed, continue for the desired number of repeats and end as suggested for the two-color version.

Previously knit, not using this method, a sample with the ground behind the shape dropping stitches and one in 2-color with shapeshifts For a while, Camino bubbles were a popular topic and created with dropped stitches, for the series on the topic search 

 

 

Knitting with “unusual” fibers/ elastic 1

Decades ago UKI used to offer 92 colors in a 3M elastic, and for some time lots of folks were experimenting with using it as the second color in fair isle. A company now defunct called Impresario used to even sell pattern books for garments using the technique, with the no stretch ground yarns creating ruffled details in cuffs and sleeves. One of my students during that time made a whole collection where the elastic was used in shaping segments of pieces and even in a whole dress. Since pleating, folds, blisters, bubbles have been intermittent themes in my blog posts the elastic and “unusual” fiber use seems to be a natural follow up in my swatch knitting experiments.
Early published designs can be found using elastic in patterning. Thread lace was an early feature in Silver Reed machines, so if that is a fabric that is attractive, downloading Studio specific punchcard books or those for their electronic designs is well worth it and provides a wealth of inspiration for the related knits. The knitting technique is often referred to as punch lace in early pubsIf a clear color contrast is desired, FI is the better option. One such source: In an earlier post on “pretend cables” I shared a demo swatch from my teaching days (shown sideways) that became the springboard for the mentioned student collection
and its accompanying punchcard repeat:UKI is no longer available. I recently acquired some Yeoman elastomeric nylon-lycra yarn. The latter is supplied on 1450 yards per pound cones in 23 colors.
There were several things to be sorted out for the elastic to feed smoothly. The first was to separate it into more than one cone with the intent of using at least 2 strands since one did not seem to work predictably. After trying a variety of trial methods including bypassing the tension dial in the yarn mast, ultimately the best results were obtained by threading the elastic as any other yarn but taping the metal disks spaced apart in the assembly thus reducing the pressure and upper tension on the elastic as it advanced through the mast for knitting.
The normal threading

Here the white yarn shows position beneath the pin and scotch tape in place to adjust the amount of pressure exerted on the elastic.As a matter of routine, even if the goal is to knit the fibers double bed, it is always best to make certain one gets familiar with yarn feeding, tensions, changes when larger widths of knitting are attempted, etc. on the single bed. The first tests were knit using the fair isle and thread lace settings single bed. Though I am using  img2track to download to a 930, I do not have a 930 carriage (910 ones do not have a thread lace option), so I worked the swatches using a punchcard model carriage. The repeats used were planned to include borders on each side to ensure those stitches would knit in the second, B feeder color in fair isle (black squares, punched holes) or together in white squares (unpunched holes) in thread lace. Fair Isle produces a double set of floats on the purl side.Thread lace produces a single set of floats (in this case the elastic), the white border is not visible in the repeat below, it is the same as the above fabric, with colors reversed. I prefer the single float backing. In addition, for these fabrics the elastic is placed in the A feeder, the yarn in BI found the standard sinker plate kept having issues with the thread lace option, getting needles caught up in it as it attempted to move across the bed. The sinker plate that was provided with the punchcard machine was actually different, and when I switched to using it I had no further problems. Arrows point to differences, I have long since replaced all brushes with wheels on all my sinker plates. Be aware when purchasing any of them that the bulky KM ones are slightly larger.A second thread lace variation:
the multiple folds and creases, as opposed to smooth blister in all the above, are very interesting to me.
There are many scientific papers being written on 3D knitting that explore pleating achieved by using knit and purl combinations which to some degree could be emulated on home knitting machines equipped with a G carriage. Other work explores properties achieved by using elastics in the mix, they can be found by searching for “axometric knits”.

Many interesting pleating effects may be achieved by using knit and purl combinations. Unless one has a mechanical aid such as a Gcarriage transferring between beds can be tedious and hard to do correctly for lengthy pieces of knitting. I illustrated one sample in the post I decided to now test a similar block structure using the thread lace setting, first with a large check and then a far smaller oneThe spots, where the elastic and yarn knit together, are compressed, so the results are quite different than what might be expected from studying the chartA quick, imperfect sample using a fine cotton and a single strand of the elastic, each with its own upper tension disk adjustments.a close-up of the elastic and cotton, though they are knitting stocking stitch together, the cotton does not have the same stretch factor, so the loop formation as viewed on the purl side is different  What of knitting on a double bed? An axometric shape, a tentative repeat worked out and in turn elongated X2 and tiled to check alignment. The original repeat is composed of an odd number of rows in height. Usually, double bed knitting relying on color changes or automatic DBJ KRC separations require an even number of rows in the motif. The first sample was executed using single-ply cotton and elastic yarns respectively, fed through separate upper tension disks but knit together as a single color. The swatch is 72 stitches in width but measures only 14.5 mm (5.7 inches) in width, producing a gauge of nearly 13 stitches for inch, not achievable when knitting with standard fibers on a standard 4.5 mm machine. The pattern is subtle, more visible on the knit side, hard to tell there are pockets in the knit. The cotton is space-dyed, and as true when using such yarns, that causes some confusion in immediately identifying a clear pattern. The ruffled effect is simply from a plain knit start and color-changing stripes to test tension and knittability on the planned needle width. Machine settings: opposite part buttons,  no liliHere the same pattern was executed on the same number of stitches with the white wool used above, but the elastic was plied with a 2/24 acrylic yarn and knit as DBJ with the blue, stretchy combination creating the solid color backing a comparison in scale My future intent is to try for some of the 3D shapes obtained with racking, but prior to that, I tested the yarn and tensions on some simple every needle rib racked patterns. Because of the movement required across the metal bed for racking to occur, I chose to continue using the same wool as above, rather than thin cotton likely to break from the stress of those movements. A plating feeder would do a better job of distributing the colors, which here become muddied as seen any time 2 contrasting colors are knit together and are used as “one strand”. Racking every 2 rows (swatch bottom) will stress the yarn less than every one row (swatch top). The knitting was fairly easy at tension 4 and 3 respectively. Both carriages were set to knit in both directions. The weighted rib on the machine measured 16 inches, 10 when off it and relaxed. The width nearly doubles when fully stretched. I was curious to try a pattern previously tested in an all woolThe stitches were quite compressed, the color mixing makes the shapes harder to trace, the fabric measures nearly double in width when fully stretched in width, the needle arrangement is more visible at that point.The needle arrangement was changed. The finished swatch measured 24 inches when weighted and on the machine, approximately 18 inches when off and relaxed. The maximum width was expanded from 4 to 12 inches The “pleating” arrangement is noticeable in this view Working with a similar arrangement I decided to try having patterning on the top bed, with the aim to tuck on the single needles in work in the repeat (bottom line of black squares). Not all ideas are an immediate success. Wanting to see the effect on the single-ply wool I began with that at the tension that appeared to be required for knitting it along with the elastic and stitches were far too loose.I had more success and a bit better definition of the fabric by knitting with both strands together from the bottom up. In an effort to attempt to have better color distribution I used the plating feeder and had some issues with stitches not knitting off properly. The result was not significantly different than that obtained by simply feeding both yarns together. When using plating feeders both on the single and the double beds one of the yarns may have a tendency to jump out, to prevent that from happening here is one “hack”.The tuck stitches do help with the definition of the shapes, as do the dropped stitches, a fact worth keeping in mind with a return to pleats and their formation, but likely in another post. Likely the last test in this series, I attempted a version of dragon scales at first using a yarn I knew would be too thin for the effect alone, then added the elastic. The combined yarns did not tolerate tuck and racking combined, so I then used slip stitch <– –>. The yarn alone sample was too loose and thus nearly flat and when the elastic was added the resulting knit became compressed and lost any semblance of 3DThe same yarn as above, also knit in tuck setting, showing the difference in size and dimension between slip setting on left, tuck on right As with any knitting, keeping an eye on what your yarn is doing still matters. Such as this will lead to a series of circumstances that may bring your project to a far earlier end than planned ;-(
A very last effort at attempting the scales with elastic and wool knit at a far looser tension that in previous tests, ended when elastic broke as a result of above, IMO an unremarkable fabric

Blistered stitches dbj

A review of some of the terms used in describing fabrics with raised designs in various patterns:
blistered fabrics: two rows of the main color are knit the same as in standard dbj, but more rows are added and knit with the blister color on only one of the two beds used to create textured pockets. Technically they can be executed in a single color as well as in two colors per row. The extra rows result in the blisters being raised or lifted up from the fabric surface, they are often also referred to as pintucks. These fabrics do not have the width and stretch of many other 2 color dbj fabrics.
When exploring this family of knits, use plain, fairly smooth and thin yarns. This is a fabric where pressing should be avoided so the texture is not lost or altered. For setting the pockets created sometimes slipping a wire or tool through the bubbles will do the trick as for any hems. Simple, bold patterns work the best. Spreading the texture evenly throughout the design will decrease distortions in width. Leaving needles out of work combined with racking can alter the basic technique considerably.
In the two-color version, a double thickness fabric with a crumpled face side and a single color backing is created. The blistered areas are knit in one bed only, the rest is full needle rib with floats from each blister enclosed in the fabric.
Begin with a repeat that is elongated X2, the jacquard separated pattern needs to be double marked. Needles are arranged as for DBJ. For 2 colors the main bed is set to slip <— —> throughout, but the ribber settings need to be changed and set to knit and slip alternately for 2 rows to produce the single color backing.  Good needle condition is a must if occasional stitches are dropped on the ribber they can be repaired when the work is off the machine.
Ripples are created by setting one bed to slip and the other to knit for several rows, then setting both beds to knit simultaneously to join the tucks in repeats. They are selective pintucks, on every needle rib. The main bed is set to slip <—  —> throughout, the ribber carriage is set to slip for 4 or more even numbers of rows, and then to knit for 2 rows (this number may also be varied depending on the specific pattern). This is a fabric that likes to be weighted evenly. Tight ribber tension will help increase the definition of ripples. As in any multicolor fabric, each set of ripple stitches may be knit using a different color yarn.  Some designs tolerate having the main bed set to tuck rather than knit.
Brother machines often are limited to 4 rows knitting on the bed creating the ripple before closing the rib.
Transferring blister stitches to main bed, with a shadow lace tool or a transfer carriage is referred to as “shadow lace”. Adding blank rows in your design makes it easier to have a transfer point to the opposite bed. Using a plaiting feeder will add color contrast.
“Nopps” which are essentially small bumps on tightly textured tuck stitch grounds require careful tension adjustments.

An image was shared in a machine knitting group on Facebook. It cropped up in Pinterest, could be traced back to some Russian knitting forums and a how-to knit query was made
There is an Italian language youtube channel with a throve of machine knitting videos, one on jacquard groffato , executed on punchcard machines, with a companion video on punching the card. Groffato means embossed.
Points to remember: the more needles on either bed knit alone to create the pockets, the more the tension used needs to approach the one for single bed knitting there with the same yarn. Large shapes are best used, represented by white squares /unpunched areas. Punchcards such as ones published with large unpunched areas for thread lace designs or tuck stitches with large punched areas color reversed can work once the principle is sorted out.
The setting used in the video is for tubular/ circular knitting.
The all punched rows in the video actually match rows that would be knit anyway because the main carriage is set to knit in one of the two directions, not slip. Two yarn ends are used, which could result in a fairly dense fabric with limited drape. Switching to a single yarn end can alter both considerably.
In designing your own patterns for testing it is best at the start to keep shapes simple and not worry about repeat variations.  I am working on a 930 using img2track, but my repeat is 24 stitches wide and usable on a punchcard model, its source is another pin. To make the design twice as long, when planning an electronic download, the image can be stretched in the design software or by altering the stretch factor to 2 in img2track. Tiling the design prior to download can help one imagine the potential results in using it for an all-over pattern or what its appearance might be if the repeat is shifted into a brick configuration.
Use a familiar, smooth yarn in an easy to see color. Tension changes alone can change the dimension in the textured surface, so having a “normal” baseline for tensions and “feel” while knitting from previous uses of the yarn double bed gives one a good starting point.
The “flower” image used in my tests is shown here in the original, and then is color reversed so its shape will blister, not the ground. Below it, on the left, the image was stretched within img2track, on the right within my design program which happens to be Gimp. In both instances, the original 24X24 design becomes 24X48 in actual knitting

The tiled image for both a standard repeat and a brick configuration shifting by 12 stitches to the right are not thrilling me, but the goal is to explore the knit technique, modifications in the original or even abandoning it can happen later My starting samples were knit on 32 stitches, not enough to get a sense of or a good view of the horizontal repeat of 24 stitches. At first, I used the design version with no horizontal black lines in the download. The difference between the every needle rib at the bottom of the pieces and the slip stitch blister fabric is easily seen. Slip stitches are short and thin whether single or double bed. On the left, I used the tensions of 4/4, as for the particular yarn in past experiments. On the right, the switch was made to 4/2. The tighter ribber tension made the blisters more pronounced. The non selected needles on the main bed create the pockets. Because functions repeat for pairs of rows in this design, the first preselection row can happen from either side and cam buttons may be reversed with similar results as seen in top vs bottom below. Opposite part buttons are used as in option A or B.As I have explained in the past, I tend to leave the slide lever permanently in the center position. It becomes one less variable, forgetting to reset it can result in errors in gauge and more mishaps when knitting multiple pieces where gauge matters significantly or in reproducing previous work. The “striped” repeat produces essentially the same fabric. The knit carriage may be set to slip in both directions when using it since the row of all punched holes or black pixels will knit every stitch on every needle selected while in the previous samples the cam button set to knit in one direction performed that function regardless of any markings on the design repeat.  The ribber is set to knit in one direction, slip in the other. Reversing sides for cam button settings produces the same fabric  

To my mind, the best shapes for this sort of surface design are clearly geometric ones. My eye sees them as more easily identified on the surface of the resulting knit. Sticking with the original “flower” however, here it is after a bit of editing of just a few pixels followed by a larger swatchThe Stitchworld Pattern Book is another good source for predesigned repeats, many in units suitable for punchcards as well. I was attracted to the possible geometry in this particular patternThe repeat I chose is designated as suitable for the Garter Carriage. It is 24 stitches wide by 48 rows high, shown below as provided, charted in Gimp as .png for download, and tiled to help visualize how continuous repeats might line up. The image .png was downloaded with img2track to my 930, with a stretch factor of 1.0, retaining the original repeat sizeThe resulting knit is interesting on both its knit and the purl sides, clearly shows how the “image” is shortened in slip stitch techniques, elongation would be required to create more of the diamond shape Final decisions are often best made after a period of rest for both the knit and for our eyes. It is only in the actual knitting that the shapes can be finally evaluated, worked on further, or abandoned. One of my own best selling felted items for more than a decade was born from an accidental effect on a large swatch that nearly landed in the trashcan after it became something different than what I had planned or expected.

DBJ: more than 2 colors per row 2

I am taking a break from this topic for a bit. At some point will add at least one more swatch and perform another edit. My eyeballs and brain need to be looking at some single color knitting and no more than 2 color squares for a while 🙂

My first attempt to use a 3 color automatic separation was with img2track. There are 2 oddities for me using the program. One is that the default selector setting is for a single motif, perhaps on the assumption that the main use would primarily be for large scale, nonrepetitive images. The other is that even if working with 2-row color changes with each color in each design row knitting for 2 rows, the first preselection row must be made from the color changer side. This is a necessity in Japanese color separations for 2 color work where the first color knits for only one row on moving from the right side to the left, but if 2 colors with the same selection are required at the start, one row of the 2 appears to be technically eliminated as a result. I had expected to use 3 shades of grey, a pleasant surprise: the program can actually import a 3 color other than grays. The test was using the 11 stitch repeat A pleasant surprise: the program can actually import a 3 color other than greys image. Using Gimp, images worked in RGB can be reduced to indexed 3 colors for this purpose. If there are rows where there is no color represented, then as explained later in the post, the indexing should be to 4 colors, not 3 for the planned for import to work properly.The design is automatically flipped vertically, so it will appear as intended on the knit side of the fabric. Yarn colors may be placed in the color changer matching the order in the assigned color numbers to match the placements in the original image. The program automatically adjusts for the vertical stretch, which changes the aspect ratio of the shapes. On my 930 I received prompts on which color to change to prior to doing so, eliminating any confusion. With no such prompts generally one can tell which color was knit last because it will appear on top of the previously used one on the left of the knit. With a stretch factor of 1 selected in img2track, the image height was reduced by half.To achieve a look closer to the intended shape,  the repeat needs to be rendered twice as long. The stretch factor can be adjusted in the program itself to 2.0

In the past, I have preferred to elongate the design prior to importing with plans for download rather than to rely on memory for changing settings either in the download program or in the machine itself in future uses of the same design.The same yarns, tension, total number of carriage passes and settings were used showing the difference in aspect ratio between single color per row knitting and the img2track built-in color separation. The width of both swatches is essentially identical.

Images may be loaded into the program without the cable being connected to the machine. Error messages do appear with download attempts if the cable is not properly in place. The machine also needs to be powered on before the program is launched if a download is planned. I am working in Mac OS Mojave 10.14.6, have no present desire to upgrade to Catalina.
Executing fabrics that will knit each color in each row only once for every 2 passes on the main bed: back to that original repeat Here it is used as drawn, note vertical stretch set at 2, will be cut in half by the software, getting the image back to the original height l0 X 3 = 30 rows required for all colors to knit in turn; there will be 60 carriage passes to complete one single repeat.The 930 will provide prompts for the next color to be selected by pushing the matching number button on the color changer, avoiding any confusion in terms of what should be picked up next. img2track will also flip the design horizontally automatically so the image will appear as originally drawn on the knit side. Images are loaded as single motifs, so the change in the selector needs to be made manually for an all-over pattern.

In order to have each color in each row knit only once: cast on with preferred method and color. Set up the machine so that the yarn colors are placed in the color shown in the image presented by the program to match your design. End with the machine on the left-hand side for the first preselection row.
COL: set both carriages to slip in both directions and all its needles in B position, set lili buttons if not already in use, pick up color 1
knit one row to the right
COR: knit to left, color 1 will knit for a single row
**COL: change color, STOP! Push back any needles on the top bed back to B position, as you knit to the right the ribber only will be knitting, knit one row to the right
COR: preselected needles will knit in the color last picked up on the way back to the color changer, knitting only one row in that color on the main bed as you return to the left**
repeat the last ** 2 steps throughout. One can get into a rhythm. A cast on comb, part of a garter bar, or any tool of adequate width can make it a quick process of pushing needles back to B when needed to
trust the software, not the selection expected by your eyes.
My swatch seemed to be growing in length at a faster rate than I remembered in the last exercise, here the results are shown side by side with the fabric executed previouslyObviously a success in terms of the single row for each color reducing elongation of the design shape.  While knitting occurs using the same yarns, at the same tensions, there is a clear difference in the length of each stitch on the main bed and their appearance. The reverse. Checking the ribber carriage I noticed on the left side it was set to knit only, not to slip: OOPS!N is king, so the ribber set as shown is knitting every other needle when moving to the right, but even with lili buttons in use it knits on every needle when moving back to the left. Every other needle on the ribber will then be knitting for 2 rows as a result. The more knitting on the ribber for each pair of rows, the longer the stitches on the opposite bed. The backing is an interesting variation (half) birdseye. The elongated stitches on the main bed show more of the backing in between their shapes, it is referred to as bleedthrough. In some instances, the result can make the knit surface resemble weaving and its appearance far less familiar in a surprising, pleasant way. Beauty is in the eye of the beholder.
Remember always to double-check all settings at the start of any process in case something was missed or magically moved, and keep notes.

I was asked on Facebook whether the technique shown here is the same as the 3 color slip (skip) stitch patterns in the Stitchworld pattern book, my response: some of the stitch world patters for 3 color slip are designed for or may be used on the double bed (often single bed as well). For instance, patterns 392 and 394. The original designs are rendered color separated. Numbers on the left suggest the order for color changes to achieve a look similar to that in the swatch photos. Assuming the pattern is not easily accessible because of its being built in your machine’s memory, it would have to be entered into a paint program manually to make it available for import and in turn for download. Note that the color-changing sequence may change over the course of knitting the image, so prompts or notes of some sort would be needed to keep it correct. Each color in each row knits twice after each color change. My goals in my blog posts so far have been to keep a constant color changing sequence with each color in each row of any personal design knitting only once. I did it first with my own color separation, then, in turn, used the 3 color separation feature in img2track to achieve my desired result. Here are 2 images from the Stitchworld section in question The images could be replicated as given in a paint program, using only one color for the squares, but “should be reduced to black and white”. Attempting to import an indexed 2 color image drawn in a color other than BW may result in strange results. That said, if glitched knits are the goal, the above could work just fine. Curiously, here is the same process, using a different color, and a successful import. Checking again, I had forgotten to save the image after indexing it from RGB mode to 2 colors. and a test with another color 
Drop stitch lace periodically comes up, I have written several posts on the technique, now considered the possibility of producing it in 3 colors. The resulting fabric tends to be long, thin, and in need of blocking. There is no way to avoid the striped ground. Passap knitters often refer to this type of knitting as summer fair isle. I adjusted the repeat widthNote to self: if you are determined to use a punchcard carriage on your electronic machine remember there is no KCII to cancel end needle selection!
In order to knit this fabric stitches must be cast on in whatever method you prefer, but prior to any patterning all stitches must be transferred down to the ribber, and the main bed needles are placed in working position but are empty. Because of the single row knit for the first 2 design rows of color one, the start is a bit finicky. Alternative start follows lower in post
COL: KC II, main bed set to slip <– –>, ribber stays on N throughout, no lili buttons. Knit one row with color 1 (ribber only)
COR: as you knit to return to the left, the color 1 preselected needles will knit, while the ones corresponding to color 2 will preselect
COL: carefully drop any stitches on needles with color 1 on them without disturbing the new needle selection for color 2
**COL: change color, knit to right
COR: drop the stitches knit in the new color, make certain all needles are empty and in B position, knit back to left and needles will be preselected for the next color**
Repeat the ** to**
Again resulting fabric is narrow and long, it may take a bit of squinting to recognize the design. A single repeat results in about 3.5 by 9 inches of knitting, a far cry from what might have resulted in a single row per color design row dbj virtually shown here in a tiled format

The question then comes up re dropping only one of the 3 colors. Using the manual selection described above, the knitting on the top bed would need to be canceled on every color, every row except for the single row in the chosen drop stitch color. To my mind, that is too much to keep track of for any length of time. It would be easier achieved with specific self-drawn color separations.
There is a lot of testing that can go into developing any fabric in unfamiliar techniques that may or may not meet our expectations or our “like”, it all contributes to learning regardless of whether the tests evolve into projects.

My last post on drop stitch lace in from single color to two: revisiting the techniques on brother machines

Reviewing what happens within the program one more time, highlighting significant items to verify before beginning to knit Getting that first row to knit twice instead of a single time if that matters in your technique or is your preference:
advance design row to last one in the sequence, in this case, 30
in the 930 when the pattern is loaded, using the down arrow key gets to the last row in the downloaded pattern more quickly

COL: set machine to preselect pattern, the next 2 passes would need to not knit, so both carriages are set to slip in both directions
knit one row to the right
COR: number 30 design row flashes
knit one more free pass to left, row 1 of color 1 will preselect as you knit
COL: number 1 design row flashes
check all settings, main bed set to slip <– –>, ribber set to slip <– –> with lili buttons, and with an even number of needles in work for standard dbjpick up color 1 in yarn changer
the resulting knit design will be elongated
COL: knit one row to the right.
As you knit the first row of color 1 design row 1 will knit, row 2 of color one design row 1 will preselect
COR: knit back to the left
as you knit back to left row 2 of color 1 design row 1 will knit, row 1 of color 2 design row 1 will preselect
COL: pick up color 2,
continue in pattern changing colors every 2 rows

In designing your own, small repeats can easily be rendered even in a simple paint program. Larger, more complex ones, may best be worked using layers and masking in a variety of programs ie. Photoshop or Gimp. It is possible to combine 2 color dbj and 3 color dbj in the same piece simply by using different color separations for each segment, but the look of the fabric in terms of the length of each stitch on the knit side may be quite different when moving from one segment to the next. Of course, the backing will change as well. Though the aspect ratio of the design changes in terms of height when one knits 2 rows for each color in each design row, it remains the easiest separation method. Adding the hand selection as described above so that the main bed knits in one direction only helps reduce some of the extra height, making the original image more recognizable. There is no option within img2track to perform the action automatically in terms of adding the necessary blank rows to replace some of the colored ones in the separation.

Passap knitters are not left out of this idea. Passap preselects pushers. On the E 6000 Tech 179 emulates the built-in KRC option in Japanese model machines. My guess was that technique 180 for 2 colors, perhaps 197 with both arrow keys on the back may work for 3 colors. TBD in my next spurt of knitting activity on it. That said, the console built-in designs may be used cross-brand. It is possible in Passap to layer repeats in order to add the third color to the mix. Here is one sample reworked for use on Brother and downloaded into img2track. If black and white repeats are already in your library, one may easily recycle them adding a third color. Here I did so with a repeat intended for a very different topic future post. The image was altered and tiled in Gimp for a repeat alignment test and is also shown imported into img2track for possible knittingWhat of images that are published in punchcard machine references? It is probably best to start with smaller repeats. That said, this is from a Deco pattern book.  Deco punchcards were 40 stitches wide, could be joined together in length as can those for the Japanese models The image of the separation on the above right has not been proofed for accuracy. If it were, the next step would be to elongate it X 2 for color changes every 2 rows. One method is to elongate the original in a paint or photo processing program. The width is fixed (40), the height is scaled X 2. The resulting BW indexed image may be imported, using a 1.0 stretch factor, it remains unchanged. When I tried to elongate the unstretched image in img2track by 2.0 my first try failed. It turned out the reason was I had saved the import without first indexing it to 2 colors. With that corrected, the result matched the one from scaling X 2 in height in the paint program
For years now I have been doing color separations which at first could be extremely slow, one pixel at a time. With increasing familiarity with Gimp and Mac Numbers over time, I have been able to decrease the speed to achieve them immensely. So here, with img2track I now have a program that can work with and separate multiple colors at a time (up to 6 in its pull-down menu option). Here I returned to my first separation in 3 colors for the now-familiar repeat A, elongated it in the paint program B and imported A into img2track choosing 2.0 stretch and 3 colors C. I can totally live with the fact the colors are not the same. The color changer can be set up with my chosen colors in any order I choose

In my first tests with charting a repeat missing any color in some rows, I had scaled the original image taken from a spreadsheet to the wrong size in Gimp, so operator error resulted in crazy results in img2track.Here the image is scaled properly for each color represented for a single row in height, and also scaled again for double-height for possible knitting in Gimp. The Gimp scaling failed to be accurate for me (second image from left) until I indexed the original to 4 colors as well instead of 3. The no color rows as we view them actually serve as a fourth color in the separations. Importing the proper size png into img2track for separation of 4 colors per row now gives results that make sense: note the daunting estimate for the total number of carriage passes for a single repeat height
If the ribber has knit on every needle by its return to the color changer and the machine is set to slip both ways with no needle selection on the main bed, the “no color” can be executed as an empty yarn holder in the color changer combined with no yarn in the feeder.  The rows involved should simply not knit on the top bed, with no dropping of any of its stitches since no needles will have been selected thus coming forward with the yarn in the hooks and traveling behind the latches and in turn, slipping off the needles as a carriage with no yarn pushes the needles with now empty hooks back to B position.

In testing concepts, I prefer to work initially with small repeats. Punchcard books can be an excellent source, but the Stitchworld books have the advantage of actually showing a single repeat for each design, so an 8 stitch repeat, for example, would be shown as such and it would not be up to the person using it shown in a 24 stitch card one to isolate it. I randomly chose pattern 394. I realize that if used from a built-in library of patterns in any machine model the prompts may be provided by the machine, but here I am looking at simply duplicating the pattern for import into img2track.

After duplicating the repeat and associated numbering using Numbers, these were some of my results. A pleasing surprise was that colors in the 2 color import need not be only black and white. That said, the pale green failed, the red did not, and the results from importing both the red/white and the black/white were identical. Another future time saver for me to keep in mind. 

If colors were assigned to each pair rows representing each color used, the white squares were read as an added color on import, and the only way to have those few blocks for the 4th color to show up in the visual representation in an imported repeat was to assign a 5 color separation, resulting in a scrambled pattern. Removing the few squares in color 4, will produce inaccurate separations for actual knitting of the given pattern whether imported to be rendered for 3 colors or 4. The black and white on the right is the “correct” match, leaving any prompts for use of shifting color changers to be tracked somehow by the knitter.Punchcard knitters may have the easiest time to knit variable color sequences since cards may be visually marked up with colored pencils matching needed change locations and taking into account your eyes are a number of rows above the row being read by the card reader. This number depends on the machine brand and model.

Some spreadsheets that may help with tracking row color changes or other regular actions on paper: 2018/04/tracking-rows-1.pdf

I have been asked about the position of the slide lever being fixed in my dbj illustrations. I have found the alternate positions can be wild cards, would rather make adjustments in carriage settings if needed rather than let the factory settings do some of the work for me. If the settings are accidentally in the wrong place as multiple pieces are knit, or in knitting ribber bands for garment pieces, the gauge is changed if the alternate setting is not adjusted and kept constant, and that may not be noticed until the piece of knitting in question is completed, needing a restart. With 15-20 machines active in each studio class and lab session, out of habit, I tried to reduce as many variables as possible.

A video resource on using img2knit for 3 colors per row knitting with blank color rows in the design by Tanya Cunningham, and a Ravelry thread on the topic

 

DBJ: more than 2 colors per row 1

I began to machine knit in the glory days of using the tool and developing techniques. There were internationally attended seminars, hosts of wonderful teachers, and a community of potential peers brought together physically in pre-internet and online forum days. Punchcard machines were the standard. As more electronic models became available it was not uncommon to find the rep for DAK at one end of the market spaces at seminars, and Cochenille at the opposite end, promoting early interface and design programs. My choice at that point was the Cochenille products. I attended design school beginning 1989, the computer lab at the time was all Amiga, and I never really became interested in DAK or for that matter, Garment Styler. I was up and running soon with Bitknitter for the Passap, had the option of the Forma on the Passap or the Knit leader on Brother for less traditional shapes, and the magic formula worked for any of the math I needed in days of using graph paper or that other paper that has lots of lines in it for keeping notes. The calcuknit and styler at the time worked on established default curves, the same that could be achieved by charting math or even simply connecting lines between dots on graph paper, drawing lines in between the dots, and following the drawn lines guesstimating increases and decreases along the edge of the drawing. I have never had any experience with DAK, was never really interested in owning it.  😉
A bit of early low tech: when aspect ratio mattered pages of acetate sheets with vertical lines spaced at different intervals could be lined up atop of each other and placed on a design to approximate knit gauge, and the result could then be charted out and planned for a punchcard repeat or intarsia. Some acetates were sold gridded to approximate stitch and row default proportions, there were also published paper charting aids for both standard and bulky gauges. Some examples:

Laying acetate or even plastic wrap on the computer screen itself and outlining designs and processing them with overlays, was a version of “poor man’s digitizing”. The technological advancement of black and white security cameras used in combination with RGB filters made the first digitizing of non-repetitive images possible.
I had never really planned on teaching. As it turned out I interviewed a few weeks before completing a textile program, had several finished pieces with me from my undergrad work, and was amazingly hired instantly as the machine knitting instructor for apparel and textiles. I found myself faced with a Brother punchcard lab and a summer of crash learning on the specific models followed. In order to teach effectively, I learned to analyze and break down stitch types and techniques in order to help others understand them. Summers would often include studying trends and knitting lots of swatches. Many of those are still in a couple of bins I held onto when I downsized a few years ago, giving up my studio space. It is that analysis that keeps me interested still in working out how-tos. Although I use electronics, I still like to break things down when I can so punchcard knitters are not left out.
Getting to the topic of multiple colors and nonrepetitive images in the “early days”: punching holes in cards is time-consuming and without the aid of electronics or specific software, color separations for dbj and assorted double bed fabrics need to be worked out manually before punching, and accuracy is important. Consequently, some knitters found compromises to achieve the look of multiple colors per row. Julie Schafler Dale’s Julie-Artisans Gallery on Madison Avenue became the central plug-in point for the wearable art movement, eventually representing artists, some of whom are no longer knitting, and some may still be found presently online
Susanna Lewis, Norma Minkowitz, Jean Williams Cacicedo, Linda Mendelson,
Nicky Hitz Edson, and not caring about floats, often working single bed with some linings and over-dyeing additional colors  Janet Lipkin .
The non-repetitive image was worked out in length by dividing the image lengthwise into panels often 40 stitches wide for use with early Passaps and continuing on to the desired height.  Widthwise, the design was split into the maximum width of 40 stitches with added seaming allowance and consecutive panels were joined to compose the large image. The kimono was the most common shape because of its simplicity in components. As for getting the look of more colors per row: multiple thin strands in color families were used in each yarn feeder. For example, one can knit with  4 strands of red shades, 4 yellow sequentially lined up, used in pairs in the same feeder. Keeping the red constant, for the second strand, the work may begin with either the lightest or darkest yellow, knit X rows, switch yellow to the second shade for X rows, switch to each of the next hues, and in theory, the final set of rows should look like a different color than the one used in that feeder at the start of the process. the ratio of red could be played with as well, expanding the range. Knitting pieces in black and white particularly allows for limited edition knitting. The third color may be applied on portions of the white, providing a look-alike for 3 colors per row. With the range of space-dyed yarns or custom dyeing blanks and then unraveling them for larger pieces to control pooling one can also get the look of more colors per row. Not to be forgotten are hand embroidery and fabric applique.

The question remains as to how to knit more than 2 colors per row on home knitting machines, and color separations to make the fabrics possible. The more colors per row, the more passes to complete any design motif. The final result may be thick and unyielding unless thin yarns are used. More rows are often knit in the back than on the front of the fabric, resulting in further elongation of the shapes involved. The easiest default separation is to knit 2 rows of each color for 2 rows sequentially, allowing paired passes to and from the color changer. This results in an elongated design, even with playing with standard backing variations to reduce vertical stretch such as in birdseye. In a post years ago I began to look at 3 colors per row and some potential issues with separations for dbj using it the initial method:

Each row will have to knit twice to get 2 and from the color changer for color changes every 2 rows, for less punching, each row can be represented once, but the result will need to be elongated X 2

The graph below shows the motif in repeat, the next column the color separation, with expanded rows, and in the third, the black indicates the knit stitches (black squares on mylar, punched holes in card) prior to elongation. 

The repeat was not workable when using the standard method used to avoid elongation, where each color for each design row knits only once. There are segments where the new color would not align properly on stitches knit on the previous row, and to get the design to work I had to amend it.
Fast forward 5 years. I now have access to both ayab and img2track, no longer use Photoshop and Excel, still use GIMP and Numbers as my way to color separate and produce charts for my blog. There are active forums both on Ravelry and Facebook with general machine knitting information, or specific to both interface options and methods for using them.

Sarah Spencer @ heartofpluto developed code that reduces the number of rows knit making the common impossibles possible. The code is freeware, has been implemented in Ayab and available there as a menu option. Adrienne Hunter’s posts on Ravelry explore the concept involved.
To begin, I was interested in using part of the concept on my own while keeping the color sequence constant ie 1,2,3,1,2,3,1,2,3 and so on throughout the piece and always begin tests with simple shapes that allow me to note what is happening to stitches, changes in scale as the result of the techniques used and started with designs where each color is represented at least once in each row. The color separation used: The ribber was set for birdseye at the start of the swatch pictured. At its top, N in one direction and slip in the other were used, with the ribber set for knitting every needle when the main bed slips them all on blank punchcard or pixel rows. The tension remained constant throughout. The KC preselection row can happen from either side with this particular color separation depending on whether one starts the design with a blank row or one containing pixels. Since 2 rows knit in each “color”, I prefer to start the first preselection row on the right. Both birdseye and N settings on the ribber produce a single row stripe on the back of the piece for every 2 passes of the carriages and completed  2-row color change sequence. The N setting contributes to elongated stitches on both faces, leading me to prefer the lili birdseye one. 

In theory, because of the way the birdseye rows set up a base for the next row of knitting,  that makes the stitches in any color workable in pattern colors. I created a new repeat for that motif working in numbers following that up, I planned for the 60 rows needed to complete the repeat, hid 30 rows,  using this menu

copied and pasted the black and white repeat on the above right, then unhid the 30 hidden rows (see previous posts using command key selections), having a new color separation repeat, created the final 2 color BMP in Gimp (whew!)Since my separation is planned on 2-row sequences, I began with COR and my preselection row was from right to left. I initially had issues with the lili buttons behaving erratically, once the ribber carriage was oiled again that seemed to solve the problem for me. I did not arrange colors in the yarn changer to match the illustration in any way, but that could certainly be done to match a chart. With COL pick up the first color in the sequences, there will be no needles selected on the top bed (no black squares on the first row of repeat). Remember to have both carriages set to slip in both directions and the rule for even the number of needles in work on the ribber. As the carriages move to the right, every other needle will knit on the ribber, the first row with black squares will preselect. With COR on the pass back to the left, the pattern squares will knit, a blank row will be preselected, and the ribber will complete a single row of the background color by knitting on the alternate needles from its previous pass. As a result, one row of backing and one design row for each color (including no color in some instances) are completed with every 2 passes of the carriages.
I had a better edge and needle selection on the ribber with an extra needle in work on its left as compared to the main bed, adjusting after the cast-on row, maintaining the ribber needles in pairs, and evaluating the swatches after the fact would probably set up an extra needle on the right side as well.

This swatch and the ones following it use yarns in 3 different weights and different fiber contents. The blue is acrylic and the thinnest of the three. Some bleed-through of the colors traveling behind the blue shapes, in particular, can be seen behind it. The magenta is cotton, the yellow wool. Better choices of both the fiber content and colors of the yarns used would improve the overall look. If one plans color changes to match chart, a  paint program can help visualize some of the possible results

What of shapes with fewer than 3 colors in some rows?Again, there is some bleed-through, and even with this technique there is some elongation of each of the shapes, but less so than with other techniques. The backing of all these fabrics produces single lines in each color used Even fairly small repeats can take time to color separate in this manner. The technique, however, is the only method available to punchcard knitters. Electronic machines with download cables and varying software open a very different world in terms of ease and range in repeat size possibilities.
Here the repeat is adjusted from 11 stitches in width to 12, making it suitable for punchcard machines, and widening the center shape by one stitch may also reduce lengthwise stretch and help it appear rounder after knitting

References for double bed single color fabrics with pockets

Another facebook thread has begun a sort of “trip down the rabbit hole”. Until I have time to swatch my theories on the specific fabric in question, I thought I would list some ways offered in publications available for download online and in my previous blog posts that touch on this area.  To start with, some fabrics are commonly referred to as pintucks, though tuck stitch is a completely different category of stitches, and they are usually shown in a single color. Understanding the repeat, however, one could plan for the shapes to occur within horizontal stripes of varied colors. 

from the Brother Ribber techniques book

Other terms: ripple ribs are a type of selective pintuck pattern in which more rows are regularly worked on the main bed than on the ribber. The main bed carriage is set to slip in both directions throughout, the ribber carriage is set to slip for four rows, and knit for 2. The width of the work needs even weight, and most likely the edge stitches will as well. The tensions used approximate that used in every needle rib for the same yarn.  To exaggerate the ripple effect, the ribber setting may be set up to three whole tensions tighter than the MB if possible or desired. Two-color versions are possible. From the Brother Ribber techniques book, note they use the term synonymously with pintucks In blister jacquard more rows are also worked on the main bed than on the ribber, creating a fabric with at times high textured. It may be executed in 2 colors as well. A “normal” DBJ card can be used, but the ribber carriage settings need to be changed with each color change. Things become far easier if the fabric is color separated for the technique and the original design is modified. Color variations merit their own posts

Sock knitting resources and ideas for machine knitting

The only sock(s) I have ever knit have been as demos in my classes. I actively dislike wearing them, and it winds up being a sheer necessity in our winters to actually break down and wear them. I have had an ongoing interest in 3D knitted, explored some pleating, have always been fond of holding techniques. This year has not allowed for as much time exploring and producing as I might have wanted, am hoping to increase both activities in the coming one.
Forums of late have buzzed with knit socks, here are some possible online resources: from machineknittingetc.com:
studio-tips-and-techniques-issue-37-charting-socks
singer-sock-book-seamed-and-circularmachine-knit-news-machine-knit-socks-supplementempisal-sock-patterns

From assorted sources: visualizing shaping sequences: aspect ratio was disregarded in order to combine several images into a large one, particularly noticeable in the middle image on the top row 😉Patterns from manufacturers: Superba manual  Passap Duo 80From a Brother pub. The original paper version actually came with knit leader patterns

There are many ways to seam join such shapes. Seam-as-you-knit is another option. Diana Sullivan offers a video on the technique. Considering its limitations: the seaming needs to occur on equally shaped segments, this would eliminate any shaping to allow for widening parts of the leg as one moves up toward the knee, so the height of the sock would need to be shortened, planning for fit. If one desires a true rib at the top of the completed sock, IMO seams at least for the rib are unavoidable, and one must take measures to make certain cast ons and bind offs for ribbed bands match in look and width. The same issue with shaping occurs when knitting socks tubular. For a tube to grow or decrease in diameter retaining its circular form, the only way to achieve the result is to increase or decrease evenly across knitting bed(s) involved, far easier to achieve if one surrenders the seamless idea and allows for a seam in the design. Here A sections would be knit first, B sections would follow with seaming along the dotted lines. The toe is a 3D shape achieved by holding, with no seaming necessary.
If one is fond of holding intarsia techniques and cumulative joins, this book is available  For advice and ideas on knitting the swan socks see https://knitterstoolchest.wordpress.com/category/circular-knitting/

From Drops design, HK, a spiral sock , and a side to side version, both food for thought in terms of adapting for machine knitting.

Small scale experiments for larger ideas: the spiral sock
Mary Thomas’ book of knitting patterns was first published in 1943, my edition in 1972. This is the usual cover photo on page 38 a repeat and instructions are offered for a spiral tube sock. The latter has no heel shaping, but traditional toe shaping can be added. The knit/purl design can easily be executed single bed by folks who own a G carriage. My mini sock was knit on 30 stitches +1 for sewing. The blocks can be varied in width depending on the required circumference of the finished tube. The extra pattern stitch in the chart is to allow for seaming a half stitch on each edge and maintaining the pattern. *After every 6 rows knit transfer the right-hand needle of every ribber group to the main bed, on the main bed transfer the right needle of every group down to the ribber**,  repeat * to ** for the desired length. There are a number of ways to deal with the toe part of the stocking. I would opt for transferring stitches to the main bed and knitting one row, using holding remove half the width onto waste yarn then bringing half the stitches on the alternate side into work. The toes may then be worked using stocking stitch, scrapping off, and seaming or grafting the stitches held on scrap to each other. My working repeat, with a 12 stitch repeat usable on punchcard machines as well isolated by the added green border testing the tiling, making certain any programming would line up Cast on for a ribbed band at top of the sock in any preferred configuration. Be certain cast on stretches enough to accommodate the finished width of the tube as it stretches to fit the leg. Transfer stitches between beds in the desired knit/purl configuration. When the desired height is reached transfer all stitches to the top bed, drop the ribber, switch sinker plates, knit a row on all stitches, divide for toe shaping. Here one half away from yarn end and carriage is knit with waste yarn and dropped off when shaping is complete, After toe shaping is finished and waste yarn is added, the work is removed from the machineBecause all transfers are made in one direction, as in any knit fabric where that happens, the fabric will biasHere the toe shaping is seamed, the twist in the body of the sock begins to showOne side of my knitting was looser than the other, something to watch in any “real” piece. Thin yarn knit on tension 4 is probably also not the best suited for any socks in terms of wear. After seamingand worn by a few cotton balls 😉Lastly, it is possible to knit socks sideways (as well as gloves), usually in garter stitch and in hand knitting. This is a crochet illustration that points to the general construction method.

On the machine, the shaping would need to occur with increases and decreases rather than holding to create the heels, and toes could be shaped, probably best by full-fashioned increases and decreases. There would be at least one grafted seam the width of the sock, the cuff could be added with the side straight edge picked up and knit from there. To get shaping to match, in theory,  one option would be to start with waste yarn, knit to half the above  shape, scrap off. Rehang starting open stitches, reverse shaping, graft seam. Dotted lines represent open stitches, decreases and increases can be planned so that only the smaller group of stitches on one side are moved with a garter bartest swatch to follow

Twisted headband meet fisherman rib, seaming, variation ideas

The machine knitting forums in both Ravelry and Facebook have recently been buzzing with versions of twisted headbands in varied techniques and yarn weights. Tanya Cunningham sparked the discussions by showing her bulky tubular knotted version. In her blog, one may find clear instructions on fold and assembly.
I chose to knit mine in full fisherman rib, making the fabric reversible, so that facing side at the start did not matter when seaming. I wanted a single thickness and a lightweight but warm fabric that would lie flat, perhaps being worn under jacket hoods on winter walks. My first band was knit with a punchcard carriage with a magnet placed for using it on my electronic. I forgot I had removed its row counter when it was last used for knitting with 2 paired main/ribber carriages in order to clear the end of the bed. As a result, I was unable to use the row counter, as that fact eliminated the tripper for it.
Part of my plan was also to avoid bulk at the twist as much as possible. Increasing the stitch count for such warmers can easily approach more of a hat shape, and a “top” could be added to complete the piece if it is intended to be worn as one.
In terms of inspiration, there are endless sources for twisted bands available, most for hand knitting, but sometimes they can be adapted to machine knitting easily enough, especially if one also owns a G carriage. One such source is Dropsdesign , simply enter headbands, knit, in the search field.
Head sizes and what each of us determines as comfort can vary tremendously. A table of head circumferences may be found at craft yarn council, and for much more detailed charts see
The twist will take up some of the finished lengths.
My first band sailed through on my Brother 930 standard:
Cast on 22 stitches in 2/18 silk wool, tension 5/4, at the same tension as the body of the band, intentionally loose.
Knit to head circumference, checking the length on the machine with weight off periodically after weight hits floor (scientific measurement), and periodically after the weight and comb are moved up.
Transfer stitches to main bed
Knit one row single bed at a looser tension (I used 8 in this version)
Bind off around gate pegs, OK if tighter than the bottom, it will be part of the seam
Twist and fold,  rehang one side of the chain, alternate loops from the loose cast on
Knit a loose row across all layers and bind off,
Turn inside out.
Variations in color are due to the wonderful lighting in my apartment on another gloomy, rainy winter fall day.
Visualizing the necessary folds: make certain not to twist the fabric, fold it in half. Colors are used to represent portions of the finished, continuous  rectangle, dotted lines the approximate center line when it is folded

For my second effort, I switched the yarn to a yummy feeling 2/14 wool that was plagued with random dropped stitches on the Brother, no matter what I tried. That piece wound up lightly felted by hand after intentionally adding more knit length. I eventually gave up and moved over to my Passap, where things went smoothly knitting on 4/4. A reminder: in this fabric, one bed knits every needle while the opposite bed makes loops on every needle. It is helpful if the first stitch on each bed knits as carriages move to the opposite side.
Passap setting EX/ EX beginning on right and moving toward the left will tuck on the back bed (ribber setting), knit on the front (main bed setting) while tucking on front and knitting on the back when moving from left to right. Operating from the same side, the Brother settings to match would actually be the reverse of those illustrated in the ribber manual. Starting sides are in Brother instructions are often based on cast ons with 3 circular rows. I prefer 2 as I have explained in the past, it avoids a float forming between stitches on one side of the fabric. In this instance, it matters in set up only in terms of planning ahead as to which bed will form knit stitches first and having the first needle in work on that bed to ensure that the stitch will knit. In matching patterns between brands, cam settings could matter more. End needle selection brings stitches out to knit in patterning, but if KC is used here, all needles in work will be brought out to knitting position, so that is not a solution for having those stitches knit. Another thing to note in the instructions is one that might be missed upon a quick view. The Brother setting shown is for full pitch. That is because their instructions are for full fisherman knit for when every other needle is in use. If every needle were in use, the setting should be on H, not P There is also the option when one wants to insure end stitches knit in patterns such as tuck to bring end stitches out to hold manually prior to knitting the next row.
A gauge swatch in double bed tuck should be at least 80-100 rows in length. One can sometimes “wing it”. It is important if you do that, that the length is measured between the beds as close to needles as possible, and down from there without weight and after the fabric has relaxed. Do not assume it will stretch to fit, the result may be several inches too small.
A comfortable length for me in the blue wool consisted of 310 rows, knit at T 4/4. Stitches were quite small, so after transfer to the back bed, I knit a row to the opposite side at tension 8 before binding off. I also placed contrasting color yarn markers at the center point of the cast on and bind off to make seaming up evenly easier, and held things together with a double eye tool so as not to accidentally twist the piece.

The number 4 band is my first sample, knit on Brother standard. Number one got pulled on to the planned length based on the “it will stretch” assumption. A metal ruler/yardstick was marked with tape at the desired height, while on the machine the marker was reached, but when off it, the final measurement was a whole 16 inches as the knit relaxed, far too small for most human adults! Number 2 is the brother version felted by hand to hide dropped stitch and edge stitch repairs, knit and shrunk to a measurement longer than head circumference for finished width, taking into consideration the fact that stretch is lost in felting. The fit was tested on my own head during shrinking and before drying. The number 3 band is the “comfy wool” one knit on my Passap. When I taught my course, after weeks of swatching the first “garment” involving a variety of automatic and hand techniques, students were required to knit a “baby hat with earflaps” exactly as given in printed instructions, using any stitch pattern and yarn of their choice. It provided an interesting exercise in gauge and proof of the need for swatching before beginning plans for actual garments. The results varied from so small the hats would only fit a small doll to ones too large for any human head.
Knitters are often resistant to swatching, but making assumptions about results can result in not the best use of both time and materials. If working in tubular stocking stitch the tension used should be the same as for knitting of that yarn in that stitch single bed. Tuck stitch is short and fat. In every needle rib there are stitches being worked on both beds, so double the number on the top bed would be actually worked than when using needles on only one bed. Loosening the tension by several numbers on both beds does not equate to matching width for similar numbers of stitches to the ribbed version. Here is a resulting mini-band, testing the same seaming technique used in the fisherman-rib samples. It was 20 stitches in width, 80 rows in length. I cast on at a loose tension, matching that used in the body of the stocking stitch tube and knit a row to seal before setting for circular knitting.  When the top is reached, transfer stitches from the ribber to the top bed, knit at a looser tension tow to the opposite side prior to binding off and seaming (here I used 10). The technique should be usable on bulkier bands as well.The elongated stitches at the top of the “band” are due to an extra needle in use on the ribber. To review, the proper settings from the Ribber Techniques Book:

Racked patterns 5: Passap/Brother 2

I have been asked whether this particular fabric discussed in the post could be produced on the Passap. The only way to find out is to try it. The lesson already learned: use a yarn that is crisp or capable of retaining memory for maximum effect. Here the swatch is knit in a 3/14 cotton. To start with, racking was from position 0 to 6 and back. Racking every 2 rows at the bottom of the sample, every row at its topNow adding needles out of work with the expectation of folds at approximate center of each foldThis was my set up, after planning the repeat and transferring a couple of stitches on each end to the back bed for better side edges Racking started in center position 0, then swung to 3 left, to 3 right, ending on 0. I long ago got frustrated with the Passap numbering, marked the racking positions with a permanent marker from 0 on the right to 6 on the left. The knit result is definitely a rolling fabric, though a bit less so than the Brother sample which was able to move across more racking positions Reviewing some racking facts: several posts previously written that include information for racking designs on both brands

Brother racking controls: the handle, racking indicator, and pitch lever There are ample illustrations including from Brother Ribber Techniques Book in previous posts on procedural steps. Passap: racking handle is up for full pitch (point to point), down for half-pitch. It is turned one full rotation for each unit/ number change in ranking positions. Partial rotations may be suggested when some of its accessories ie their transfer carriage are used. As stated, Brother has 10 positions, Passap only 6. Passap E6 manual shows racking patterns possible with console built-in designs on pp. 118, 119, 120, 121, techniques used in racking patterns number 257-272. The console gives prompts for the direction in racking sequences. Self-programmed designs would need a separate knitting technique entered into the console as an additional “design”. This can be done with a card reader combined with a pattern download from a computer. Programs that automated the function to any degree are no longer on the market. Typically, in published patterns for either brand, if the starting point for the racking sequence is important, it will be given along with the frequency of movements such as in this design from the Duo 80 bookProgramming the front bed on Passap or main bed on Brother with tuck or slip selections begins to enter far greater common ground. Decades ago my advanced knitting curriculum included Passap weekend workshops in addition to Brother course classroom and studio hours. I spent a lot of time exploring techniques, often my manual includes scribbled notes. Manual guidelines for E6 patterning, beginning with advice for knitting them 

I have to admit I cannot always now decipher some of my note-taking or my own handwriting. The additional confusion that comes into work in cross-brand translations is the fact that some E6 techniques may only be used as programmed by the factory, others may be “combined with stitch patterns”. Getting it down to black and white squares when stitch patterns in E6 and are to be translated for other KM brands is a bit more complex, easier done from the Duo 80 instructions when an E 6 is not available for test knitting. The Duo manual is low on swatch and pattern assortment, but a small book, available online can provide inspiration for many textures, the Passap system’s particular strength. Some Duo symbols and their meaning
Many designs are based on one or both beds having needles out of work. Transferring stitches from one bed to the other can be done from needle diagrams on the Duo 80 and punchcard machines after the cast on row is closed. If the specific technique in the E6 offers a pusher selection after the first SX/GX row (262,264, 265, 269, 270, 282) transfer stitches then with locks on left, otherwise, transfer after the second SX/GX pass to the right (257,258,259). After the pattern is set up in E6 place all the pushers in rest position completely out of work.
Pushers corresponding to needles out of work on the back bed need to be in the back rail so as not to cause mispatterning if arrow keys are used. In Japanese electronics, transfers can be made after the first KC pass, making certain emptied needles are placed completely out of work. Set up the knit bed first, so alignment relationships are correct for out of work selections on both beds.
As in any ribber pattern, if the major part of the piece is being knit single bed, the tension will need to be adjusted to closer to that used in stocking stitch for the same yarn. Passap knitters have the added option of changing stripper in use to another color.
When designing your own patterns and starting the movements on either side of the machine, it will take some sorting out as to what arrangement of needles in work is best on the Passap back bed or Brother ribber is best for side edges as one bed moves beyond the last stitch in work on the knit bed. There should be no stitches on it without stitches behind them as the racked stitches travel from each side to the other if the goal is pieces that will be seamed ie. front and back of a sweater.
The E6 console may not always give the proper selection for needle set up for the front bed as seen in one of my swatches. There are never instructions for the back bed needle or pusher positions. Those need to be hand selected based on diagrams after the front bed is set up, and following the diagrams provided with each technique to produce the specific fabric illustrated. That can be disregarded in one’s experiments with needle arrangement and lock settings and how they relate to the movement in the racked stitches.
If one needs to stop the process at any point it is a good idea to devise a method of keeping track of where the stop occurred and whether a racking movement has taken place yet or not. Forming personal, consistent habits is also useful, ie. I find when racking with color changes I rack before I change the color consistently. Racking when using multiple colors often happens at the end of the color change sequence ie. 2 colors, rack after 4 rows. A bit more attention needs to happen when racking is for only a few positions. I tend to start mine on the far right at 0, so I can move the one or 2 steps and am stopped by the machine on my return, giving me an error margin on only one side.
A few Duo/Passap comparisons

Swatches: this E6 design introduces needles out of work. The E6 swatch in color below on the far left has a slightly different needle arrangement than the DUO one to its right. Technique #257 has a * beside it, which usually indicates the repeat must be altered to produce the fabric. 120 is the page on which the swatch photo appears Altered designs are listed on pp. 129-131of the E6 pattern book for all stitch types. 

The original on the left is mirrored, the selection is fixed, the height is multiplied X 6. The lengthening does not influence the design, it tells the console how many swings in each direction are planned. The console, in turn, gives visual and sound prompts for each racking movement, in this instance,  by one full turn clockwise. The prompts often start the pattern in the center 0, and begin and end with half a sequence.  The front bed is set to slip stitch, so black squares knit. Both beds will knit every needle/pusher in work throughout. After first preselection row on either brand needles and pushers in non selected areas need to be put out of work, accomplished by transferring them to the opposite bed. The design process is the same as having a fixed row on a punchcard machine, with a single selection being repeated over and over. The racking position indicator on the duo shows the start of the pattern at 0 position, Brother equivalent = 10. In the duomatic the carriage is set for plain knitting, no patterning is required. The needle out of work selection is different than the E6 sample, but the racking sequence is the same. Brother options: fixed needle selection if the fabric is created fully as a hand technique does not require any programming. Electronics could be used with the repeat drawn X6 in height so that the racking direction is reversed after the first sequence is completed and the return to row 1 of the repeat is preselected. Machines that allow for it can have info added to memo windows or even on mylars to help accuracy in long pieces. Punchcard machines could punch a single row on #1 for accurate needle selection if it falls within the 24 stitch limits or hand-select them, mark racking numbers in repeat, and go on from there.  My sample was knit in a tightly twisted cotton, and when off the machine had an interesting and unexpected fold 3Dquality

The setup is essentially the same, with white squares representing needles and pushers that need to be out of work. Tech 258 uses LX (slip) on the front bed, back bed si set to N. The duomatic pattern has a different OOW needle arrangement, the front lock is also set to tuck =  FX (E6=KX), adding another layer of texture and complexity. Needles are also out of work on the back bed.

E6000 264* is used both as a pattern and a technique number uses the X6 as well for accompanying prompts. Needle/pusher selection is for 3 in work and 9 out of work for 2 rows, then reversing it for to 9 in work, 2 out of work for 2 rows, thus accommodating the alternating color change. The Duo on the front bed performs a similar selection with the BX <– arrow key, racking is every 4 rows in both. It takes 24 rows to reach the full racking position reversal. These were the pusher selections, each repeated X 2, creating the wrong fabricWhat is knitting in terms of black and white squares if one continues:this repeat is what is required to match the technique diagramAfter the first row of pusher selection transfer 3 stitches on either side of the center 3 in each group of 9 to the back bed. This shows the proper selection, each is repeated twiceI continued to knit with plain knitting on the back bed for proof of concept, every other needle selection, and slip (BX) stitch <– –> there would compress the “wave” since half as many rows would then be knit on that bed in each color. As always, forgetting to set the lock/carriage to slip will result in knit stripes as seen on the right of my sideways swatchBelow the pattern alternates blocks of 5 black squares, 5 white, color changing every 2 rows and reversing racking direction after every 24 rows. The full repeat is 48 rows. If rows knit in the zig-zag are counted, they amount to 12 because each color slips it is not knitting for 2 rows. Note that to achieve the color reversal at the halfway point of the repeat the same color (2) knits for 4 rows, at the top of the repeat color 1 does the same.

Below tuck patterning is introduced in both beds. The front bed is knitting tuck on every other needle for 2 rows each,  easy to reproduce on Brother AX<– on the back bed will knit when pushers are up for 2 rows, tuck on the same needles when they are selected down, also for 2 rows. Brother knitters could try to set the ribber carriage to tuck in one direction only, or simply set it to knit every row

Though tech 264 states it may not be combined with a stitch pattern, I programmed built-in # 1002 X 6 in height, back bed set to slip (BX<–) every 2 rows. Racking occurs every 4.  Full repeat is 48 rows. Back bed pushers should be in work so they stay inside the edge from knit stitches on the front bed. This was a quick test. The knit side is unremarkable, the mess on the left edge on the upper right of the top photo is because I began with 2 needles in work on the back bed like in the illustration above. As I racked counterclockwise the stitches on them kept pulling away from the side edge (back bed, left). The technique continues to give racking prompts as written by the factory, so none would exist for the rows with no racking in the pattern
Back to acrylic yarn, light color for more visibility creative yarn snag on the left midway, full swing movement is shown, each is 48 rows in height. As always it helps to check whether stitches are obliging by staying on the needle bed. The top half of the swatch is shown.
In turn, I programmed # 1000 X 6 in height but pusher selection was all up for one row, one down. I left it alone, and lastly, worked with pusher selection on the back bed, BX <–. Patterning advances a fixed repeat every row or every other, determined by original hand-selected up for selection and down above rail for out of selection. The front lock is left on N (disregard front for setting it to LX) there is a whole other world of possibilities, while the console racking sequences can be used from built-in techniques.  Any ribber needle selection on Brother other than the use of lili buttons would have to be done manually.

The range of fabrics with programming additional patterns in tuck, slip, or combinations thereof along with needles in and out of work on the either or both beds increases the possibilities for fabrics with texture and dimension exponentially. 

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 1100, the 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.
