Double jacquard 3/ single bed multi color slip

Double jacquard knitting allows one to design and knit multiple color patterns without the worry of floats. The color changer (standard machines hold a limit is of 4 colors at any one time) and the ribber is required. The ribber knits the floats into the second layer of fabric on the ribber side, resulting in the term double knit. Often the main bed is set to slip throughout. Slipped (or first-row tuck) stitches become elongated until nonselected stitches knit off. The more the colors in any one row, the more all the stitches on the front face of the fabric must stretch in order to accommodate the number of colors laid behind in the backing fabric. The elongated stitches may allow for the other colors to be seen, and this is often referred to as “grin/bleed-through”. Different ribber settings may help with some of the elongation (depending on separation method) and grin through issues. The same principles used for DBJ separations apply to single bed multiple color slip stitch, and creating the initial swatches single bed can serve as a test for the DBJ pattern separation. In the series below some of the potential issues become obvious

the design repeat

The simplest color separation expands each row of the design to X times its original length based on the number of colors per row; in this case, 3 design rows expand to 6. In addition, in order to knit the fabric, the elongation function (X2) must be used, and each color for each design row will be knit twice, with color changes every 2 rows. This is necessary if the color changer is to be used since it takes 2 passes of the knit carriage to travel away from and back to it in order to pick up the next color. The result is a very elongated design. It is possible to knit the same motif without elongation, but then the yarn needs to be cut and changed on the appropriate side and each row, creating side edges not suitable for garments. One can separate any design with this method, and the motif may even have an odd number of rows. The sequence below is for the expansion of the first 2 motif rows

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)

Testing the design single bed slip stitch: the resulting fabric is dense, with lots of floats, and narrow in final width, with little if any stretch. In the knit swatch: elongation is marked, would remain so even if the fabric were knit double bed and settings on ribber to reduce elongation were used

There are 2 other options for separating colors that deal with the problem of elongation, but they do not work on every design. The separation on the left is set up in sequential 2 two row units. In a 3 color pattern, each row of the design expands into 6. The selection row is made toward the color changer. The separation on the right also retains the knit scale. In using either one must often be willing to adapt and edit the original design motif. The total number of rows is the same as the previous method, but the sequence for color one is split as seen in numbers beside the color column in the chart. The selection row is made away from the color changer, knitting a single row in the pattern for color 1. In these separation methods, the motif must have an even number of rows

The respective resulting swatches: the elongation problem is solved, but the repeat is off in the upper third of the design. Some separation programs are able to scan through your design and locate the problem areas, even shuffle the order in which the colors are knit in order to allow the separation to work, but manual solutions may be quite time consuming or at times not possible

A redesign: one method to avoid pattern shift problems and ensure success is to use units in the design that are 2 stitches high, as seen in the motif and its separation below.

In knitting, the selection row is made toward the color changer. In rows where color 3 is not represented, only the first and last needles are selected, and manually pushed back to the B position. Eliminating end needle selection can cause problems at the outer edge of other colors, eliminating blank rows from graph and knitting would require much more attention to where in repeat one is actually working, and lead to possible frequent mistakes in color sequence.

the resulting fabric, knit, and purl views

Entrelac pretender 3

This larger cousin uses the slip stitch setting combined with short rows to create an “entrelac-like” fabric on punchcard machines.
It helps to be familiar with both techniques before attempting this fabric. I am not providing specific directions for knitting, but the repeats are correct and tested, and are intended as a springboard, not a “how-to”.The related punchcard repeats.
The blue tape is used on both sides of the card to mask off holes resulting from punching errors.  The needle bed markings to help track motif placement (red for the red card, which corresponds to needle tape factory markings for repeats, black marks are halfway in between for the opposing shapes)As each set of repeats for each card is completed the punchcards are exchanged. KC direction is marked on them, with knitting beginning on the opposite side. I found the fabric more manageable when I completed and began each design sequence and color change by beginning and ending with an all-knit row in that color. The bottom of the swatch shows the difference in the side edges if half repeats are not planned for. If this were a production item it would actually be possible to work out the repeat on enough cards so they could be used as a continuous roll rather than having to so frequently reinsert and rejoin them. This sample was knit in Jaggerspun wool, and since wool has memory, the resulting 3D texture remains after steaming, resulting in a noticeable difference from the previously knit acrylic swatches.

This is the purl side with obvious changes in width and some problem yarn feeding and the knit side

There is a large number of rows between repeats, so there will be yarn ends that need to be dealt with, but they are far fewer than in knitting individual motifs, and only at the sides of the piece.

Garter bar/ short row trim

A recent MK forum request for a HK trim look alike led me to the following experiment :

the hand-knit trim

There are multiple ways to achieve knit and purl combinations on the KM. Brother garter carriage will do so “automatically” albeit slowly, ribbers may be used in combination with main beds, ladders may be latched up by hand, or one may use the garter bars to turn work over. When large widths are required the options are to use multiple panels, or to knit the fabric sideways letting the width become the length. Some HK fabrics are impractical if not impossible to duplicate on standard home knitting machines, and compromises are chosen. I tried to create a distant relative of the proposed trim, with a bit of family resemblance.

Below the short section to my garter bar is pictured. I mark every 10 eyelets with nail polish on my GBs to help with tracking stitch counts (do same with centers of ribber combs). The photo shows it in the position in which it needs to be held to take stitches off the machine prior to turning them over. The hollows under the eyelets (1) provide room for the needle hooks to slip under the yarn and catch the stitches when work is flipped over. Hollows under eyelets occur on the side with the convex ridge (2). There are many online sources for using the bars, now available in multiple gauges, including an article by Susan Guagliumi.

my working graph

I worked my edging on multiple of 12 stitches. The purl/knit symbols represent how the knit will appear when viewed on the side where the held shape is convex. Work begins by knitting foundation rows and using waste yarn at the start with open stitches on the first row of knitting if the ruffle is to be seamed/joined at its ends upon completion. The magenta/green rows represent respective whole rows to be turned to the reverse side using the garter bar after each knitting sequence is completed. Testing first is required to establish the optimum stitch size for a gauge that will allow for easy stitch movement in transferring stitches on and off the garter bar:

arrows on the blue ground indicate the position of KC at beginning of sequences

end knitting of first “purl” section COR, turn work over (magenta)

COL: knit one row across all stitches, carriage moves to the right (pink). I find it easier after holding starts to move the carriage to the opposite side by taking it physically off the machine and leaving settings alone, results in fewer yarn tangles and problems for me.

COR: set the machine for hold except for the first 2 stitches on right. I tried one stitch at a time first, but the wedge was too deep, so I began working bringing stitches to hold 2 at a time, carriage side first. Stitches could be held opposite the carriage as well, but that created a set of additional holes when one returns to knitting those stitches in the opposite direction, and a pointy edge  (segment marked with dot #2, more on a later post on miters and spirals). The number of stitches brought to hold can be varied as needed, the goal here is a symmetrical result.

COR: when only 2 needles at left are left in hold opposite carriage, knit an even number of rows (orange area, I chose to knit 4, then 6 rows in my test)

COR: when the last 2 stitches on right have been knit for 2 rows (green) transfer all the stitches to the garter bar

Get carriage to left, COL: return stitches to needles, knit for an odd number of rows (magenta, COR), turn work over

COL: knit one row across all stitches to right (pink)

COR: begin holding sequence again

I began the sample with 5 rows in between the mitered shapes and then tried 11. This is labor-intensive if produced in significant lengths, so a choice can be made depending on personal taste and patience. Though it could be attached as one knits the item it is intended to trim, there is enough going on I would probably estimate the length, take it off on waste yarn, and hang it onto the larger item. If longer, the trim may be unraveled to suit. If an addition is required it may be added on but at least working with the much larger bulk of materials will not be for the duration. Holding lever may be set to knit for single passes prior to turning work over in sections using holding, or stitches may be pushed into work by hand.

dot 1 rests on “killed acrylic”  repeat test, the remaining sample is knit in wool: dot 2 marks the extra holes when the holding sequence is changed   as described above

with five “purl” rows between turning and holding

11 “purl” rows between turning and holding

the reverse side

about half the wool portion of the ruffle was pressed, the knit became smoother, the edges less rolled. Those are properties that can become a design choice/decision

If an all stocking stitch ruffle serves the purpose this could be the start of the working repeat for using slip stitch to knit programmed needles selected to patterning position; here the black dots represent areas that knit, white squares stitches in holding. The repeat must be an even number of rows, using it as drawn, the starting side depends on whether one is using a punchcard machine or electronics

For some hints on how to use the garter bar see later post 

Entrelac pretender 2

This is another fabric combining holding and slip stitch to create shapes. Below is my first working repeat, the colored lines indicate a dividing line that would give me a black square on either side for setting up the second, split repeat to reverse the direction of the knit stitches.
I am sharing not to provide a pattern or specific how-to, but to provide some ideas for technique experimentation by readers with some experience and familiarity with the combined use of patterning and holding.

My mylar repeat as used on the 910 appears in the direction as drawn on the knit side, while punchcard models using suitable width repeats knit repeats in the direction as drawn on the purl side. Later electronics automatically mirror programmed repeats, true of my later model 930. Depending on the model in use this electronic repeat may require mirroring before or after downloading.  A newer chart of the design, with row numbers requiring actions highlighted on the left of each repeat.  Machines that automatically mirror would be selecting this  Air knitting is a good way to test pattern placement on the needle bed prior to any knitting.
When the slip stitch setting is used and segments are worked on only part of the needle bed or with needles out of work, end needle selection is usually canceled. On electronic machines, this is done using the KCII cam setting.
Each 22-row program is used across one full row of “entrelacs”.
The bottom repeat as given above preselects KCII <–,  knits left to right, and the top repeat preselects KCII->, knits right to left on the 910.
Each horizontal segment knits on groups of 22 stitches and ends on “half” a repeat.
The half repeats combined with the reversal of the knit direction result in a balanced fabric.
As the direction is reversed, the alternate repeat needs to be programmed. A bit on method:
COR for bottom mylar repeat KCII <- knit all stitches color A,
COL set the machine to slip <->, bring all but the first 22 sts on the left to hold, and knit 20 rows.
The resulting shape is being created from left to right when the top is reached the stitches at the left of the sequence will be in the B position, and the ones on the right will be in work.
COL: at this point push the next 22 sts into work, knit to the right.
COR: return first repeat 22 sts to hold position, and continue in pattern for 21 rows.
COL: bring the next group into work, and knit/move across the selected number of needles.
COR: bring the previous grouping of 22 out to hold. Repeat as needed for the desired width.
When the full row of shapes is completed and the last group of needles is preselected, COR: cancel holding and slip, knit one row on all stitches to the opposite side, and change color to B if desired.
COL: program subsequent repeat, KCII, select ->.
COR: set cam buttons to slip <->, KC to hold, bring all but the first 22 needles on right into work, and reverse the full sequence.
My swatch was worked on needles 34L to 21R and had an interesting 3D texture until I pressed it.
The differences in the size of the eyelets at the tops and bottoms of the shapes are due to the fact that when stitches are brought out to hold on the carriage side, an automatic wrap is created, reducing the size of the small slits usually formed in short row knitting.
I like to press the initial studies to have a clearer definition of the edges of the resulting shapes and the location of color changes so as not to disrupt the pattern.  There will be yarn ends to be dealt with where color changes occur, some could be knit in with the same color while making the piece. I can imagine that if the 2 rows of all knit stitches are eliminated between entrelac rows, even more variations could be done with added colors, but I personally am not “going there”.

“Automated” shell shapes

March 2020: in attempting to fill a request for a punchcard repeat, I am finding added ways of looking at the topic, will share in a later “revisit” post.

This technique combines holding with the slip stitch setting. When KC is set to slip it is the punched holes/black squares that result in needle selection and stitches knitting. Blank areas in cards or mylars are slipped/ skipped.

my mylar repeats for each segment

the swatch before pressing knit side

the purl side

the dimensional texture is flattened out  when pressed

the purl side, flipping the shell shape horizontally

using a yarn with memory and tighter tension would help retain the 3-dimensional quality if that was the  original intent

A bit on method: the repeat used for the hand technique in the previous post was changed to an even number of rows, with other adjustments.

The execution was in a brick configuration

all knitting begins on and moves right to left; needle bed may be marked to help track repeats

. for straight side edges program second mylar repeat first; I knit my sample on needles 22L – 34R

. some needles will need to remain OOW, cancel end needle selection = KC II

. COL: first selection row is done L to R with the yarn color used for the next shell sequence in A feeder

. COR: the machine is set to hold non-working repeat groups, and the KC is set to slip <->; in the half-repeat working the first half-shell takes place on the first 7 needles on right

. COL: when the top of the repeat is reached the orange row will be selected left to right

. COR: after needle selection of previously held stitches happens on that row, bring the total number of stitches for the next repeat on the left into work manually, knit one row across the 21 needles

. COL: stitches in the yellow area will be in B position; bring all stitches to their immediate right to hold, then the “yellow group” to work by hand, continue to knit in the same process across until the horizontal row of shells is completed

. COL: program machine for full, alternate pattern repeat (bottom of mylar) for a row of all whole shells

. COL: depending on personal preference, holding may be canceled for the first selection row, or stitches may be pushed back to D position and carriage kept set to slip <-> before knitting back to right and resuming working on each pattern unit

. COR: repeat process, working on groups of 14 stitches at a time from left to right

. COL: on completion of the row of full shells return to the first program, continue the process until the desired length is reached

To match casting on and binding off  I often start with waste yarn, make the decision as to how to end the piece in a way that I like based on my test swatches, then rehang the stitches from the first row and treat them as I did those in the last row of knitting.

An entrelac pretender

“Automating ” normally labor-intensive hand techniques cannot truly duplicate them. Below is one effort to produce an “entrelac-like” fabric using the slip stitch setting. The biggest advantage of this is the knitting speed as opposed to creating the individual cells using holding and picking up stitches. Some drawbacks: slip stitch floats on the reverse make for a dense fabric, and may be an issue in a garment. There are elongated stitches along the edges of the shapes at the color changes, these cannot be avoided. I am not a fan of the Brother single bed color changer so I opted for changing the color by hand. “Air knitting” helps one sort out where to set up the pattern on the machine. The fabric is knit using the slip setting, so I chose placement on the KM where I had needles selected on each side of the knit on my first row.
The pattern is begun on row 8, card locked, COL.
The first-row preselection is to the right.
COR, card to advance normally, KC set to slip in both directions, change color after 8 rows of knitting, then every 14 rows.
As in any slip-stitch design, punched holes will knit stitches, unpunched holes will skip them, creating floats on the purl side between knit stitches.  The green dot on the right of the card indicates the starting row for the first repeat, row 8, subsequent lines are reminders to change color before knitting across that particular row, taking into account the fact that the card reader is reading below the line of sight on the machine’s exterior.   Note that before the color change the yarn in use will create a float in the area that will be skipped by, and knit in the same area as the subsequent color will; at first, this may seem counter-intuitive, but it is correct, and the effect may be seen on both sides of the swatch.
If changing color by hand, remember to “close the gate” after each color change to avoid dropping the knitting off the machine if the yarn in use moves too far forward to be “caught and knit” by the appropriate needles.
With necessary adjustments in starting row and settings, technically this fabric may be knit on any KM brand.

The yarn in this test is the same alpaca/silk blend used in my shawls, at tension 6. If a color changer is used, the KC row must be from right to left with knitting rows moving left to right and back to the color changer.

2023
The same repeat may be used double-bed as well, using single or multiple colors, with the potential for variations in striping.
The minimum electronic size repeat is 12X28 pixels.
The red cells in the chart indicate the greatest number of rows, 12, that any one stitch will be held until a black pixel knits that same now very elongated stitch on the next pass.  The main bed is set to slip in both directions, and the ribber is set to knit in both with the first and last needle in use on the ribber.
The skipped stitches get quite long, thin yarn may be used but watch for any breaks or issues with gate pegs, adjusting the tension as needed.

Symbols to punchcard 1

In the chart below pattern repeats take into account the punchcard limitation of 24 stitch maximum repeat. In the sections separated by the color stripe, the bottom shows a purl side symbol chart for slip stitch, the center the purl side symbol chart for brioche/ tuck stitch, the top the repeat punched out for use on the KM with black dots representing punched holes. Keeping in mind there is a 36 row minimum for the card to roll adequately through reader, this repeat would need to be punched 9 times. If one wants to use the color changes in other than totally random manner, then the pattern repeat must be an even number of rows in height. One option is to use double length, but unless the yarn used in the repeat below is very thin, for tuck stitch that may be beyond the limit of the KM. I also prefer when knitting lengths of fabric not to use elongation; for me that makes it easier to correct mistakes. A reminder: the punchcard selection mirrors the design horizontally (particularly noticeable in letters), so the hand knit repeat need not be reversed for a match.

Below is a more manageable tuck repeat reconsidered for color changes (shown in change of ground behind punched holes). The first row selection needs to be from right to left toward the color changer in Japanese machines (Passap is on right, but console takes that into account). This is not the only color change sequence possible, only a place to start.

With very rare exceptions, tuck stitches generally must have a knit stitch/punched hole on either side of the unpunched square. This is because side by side loops jump off on the next pass, rather than knitting off in a group, making a long float in in some cases an interesting mess. Because slip stitch skips needles creating floats rather than depositing loops in needle hooks, the tolerance for side by side slipped stitches if far greater, and the number of rows that the individual stitches are not knit is limited by the strength of the yarn, and the tolerance in the machine. Both tuck and slip stitch fabrics benefit from being evenly weighted, with weights being moved up regularly during knitting. Canceling end needle selection and having the pattern repeats line up with tuck/slip on each edge may produce interesting side edges. If texture is the goal yarns that can be “killed” by pressing/steaming should be avoided.

Pleats: automating “pleating”, single bed

This post was originally written in 2013. I found myself reviewing it in 2018, and editing it with the intent to attempt a pleat sample using the Ayab interface. In those days I was using Intwined for some of my charts. The program has since been unsupported for Mac, without upgrades and a series of problems that led to my switching over to excel completely for my charts, and now to Numbers in the latest Mac OS.

I work primarily on multiple model Brother machines, in this instance the 910. Some of the information provided below may need tweaking for use in other brands KMs. “Automation” of some holding functions may be achieved using slip setting to knit required stitches. Below is the mylar sheet repeat used for my sample swatches. The setup is on working needles 21L, 19R, program for color reverse and twice the height; KCII (cancel end needle selection); first-row needle selection from left to right, and with carriage ending on the right the first set of needles selected will be those that knit, the remaining bed will slip. This is opposite to the configuration familiar in holding, where needles out to E are held, those in B or D will knit (Brother needle position jumped the letter C, they are  A, B, D, E). In this type of knitting, all needles in use on the bed should be cleared with each pass of the carriage.

I have gotten used to keeping programming numbers for  locations on mylar around a square to correspond to the lights surrounding the house icon on the 910 and worked with the following 2 options for my test swatches

In the samples below the first set of every other stitch/ black square in the increasing/decreasing angles were slipped on the non-selected needles to create/mark the inner purl fold, the second set in the area that does straight knitting tucked on non-selected needles to create/mark the knit outer fold. For the latter to occur, the cam buttons need to be switched to tuck <-> for 2 rows, and then back to slip <-> for the remaining knit repeat. Small holes are created at edges of slipped areas as miters are created, as would appear were the fabric created through holding.

A: the alternate fold areas as they appear on the machine during knitting

the fabric after some casual steaming shown on the knit side, the pleating just about doubling on itself

B: with the added knit rows, the swatch before steaming

here is the purl side after some steaming showing the change in overlap

its knit side

both fabrics allowed to “hang”

The look may be varied considerably by changing the sequencing of the number of knit stitches, and the number of plain knit rows between the EON slipped or tucked ones. Electronics facilitate that, and with machines capable of accepting programming of the whole needle bed, there is even greater freedom. The sample above was knit loosely in acrylic, the holes would be less apparent in a tighter knit. If bothersome, they may in theory be “avoided” by factoring in “wrapping” if every row of the repeat is drawn rather than every other. With only 60 squares available on the mylar it is possible to go twice as wide and produce fabric width that may suffice for a skirt’s length. With software that allows for programming the width of the needle bed, possibilities expand even more. When going double wide with a repeat such as the one above, some problems result not so much in the inner fold slipped rows, but in the outer fold of the tuck ones. As in nearly any knitting when needles have 2 side by side loops resting on them, these loops will create a float/ ladder, so the tuck rows will essentially behave like the slipped ones as the double loops are dropped rather than anchored on the subsequent pass of the carriage. In the configuration here if the double-wide button is used, one way to solve that issue would be to bring consistently the same of either of the 2 non selected needles out to D or E position (still faster than hand-selecting repeats by hand for holding), resulting in knit stitches and single tuck loops.

5/18/18  Working out the kinks: the same repeat is redrawn to factor in the reduction of the eyelets at edges of slipped areas: a partial graph showing “automatic wrap”. However, the “wrap” will fail with color reverse, and that first row would have only one stitch knitting. If double wide is used, then the wrap will happen around 2 needles, creating yet another “float”. 

its color reverse 

Plain knit rows (blanks on mylar) may be added at the bottom or top of the repeat to change pleat depth. Here is an amended repeat, discarding the “automatic wrap” idea, first prior to color reverse, then after

 
Those all blank rows would result in no stitches being knit, essentially a 2 row “free” carriage pass, and are removed. The repeat is  now also capable of being knit twice as wide if desired, adding the hand technique on tuck folds

Below the edited repeat begins design using one pixel per stitch and per row. “Automatic” wrap happens as one row is knit, while the next preselects an extra needle. The yarn travels under the extra needle prior to its being knit on the next pass from the opposite side. There will still be an eyelet, a bit larger than hand wrapping, but smaller than without any wrap at all. The EON pixels in the center of the shape are tucked. For that to happen the knit carriage needs to have the cam buttons switched from slip to tuck, and back to slip after the 2-row sequence. The fabric folds out to the knit side. The EON (every other needle) set at the top of the shape is knit in the slip stitch setting, resulting in the fabric folding into the purl side. The process could be reversed to have each fold to the opposite side of the knit.

The carriage needs to be on the opposite side of increases in the number of stitches worked. Here the first preselection row should be from left to right, with carriage traveling to and from the right for the subsequent pairs of rows. 

More variations: the slip stitch configuration below is changed to the same EON selection for 2 rows. The same could be done for the tuck fold. For this repeat, the first preselection row should be from right to the left, making that the side the knit carriage returns to after each pair of rows knit. The sample was knit in a too thin acrylic. Both eyelets and their “wraps are visible, as well as the direction of folds.

These are pleats in a skirt made eons ago, that have retained the fold over the course of many a year 

An added alternative for fold lines: create outside crease transferring EON to make a row of eyelets, create inside crease by knitting the desired row double row with 2 strands of garment yarn. “Automatic” repeat must be adjusted accordingly, whether by redrawing or punching, or using cam settings for the correct stitch formation.

Seaming should be planned on the inner fold of the fabric, depending on whether the purl or knit side is used as the “public” side, the least visible join being one that is grafted ie with Kitchener stitch.

The same principles may be applied to punchcard knitting but because the repeat size is 24 stitches the resulting fabric is one suitable for portions of garments/ accessories, in details such as ruffles and edgings. Punched holes would match the black squares in the color reversed repeats.  “Air” knitting helps determine the exact needle location required, and to decide which side the first row must be selected prior to actual knitting. The image below shows the start of only one possible partial repeat based on the last one above

I usually sample my repeats by using hand selection and holding before committing to drawing on mylar or punching holes. An even number of rows is required in this technique.
