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”.

Thinking of modules: a shell “diary”

This is the beginning of a thread on modular shapes on the KM. Much is published in the form of both how-tos and patterns for hand knit modules. One of the critical differences between HK and MK as in mosaics is that in HK garter rows may enrich the surface textures. Unless a G carriage is in use, frequent travel between opposing needle beds or turning the work over on the single bed is required on the KM to create the garter rows, which may be considered tedious and impractical rather than impossible. A question from a friend led to my beginning the topic by trying to sort out shell shapes. In the samples below two different weight yarns were used, first because they were conveniently the closest to my yarn mast, and second because contrasting colors are helpful in defining what is going on at the edges of the shapes. The irregularities in spots are operator error, the repeat pictured is sound. This is not a step by step “how-to” for those who have no experience with holding techniques, but rather a starting point for anyone who would like to play with a similar shape

the swatch immediately off the machine has a bit of 3D going on

the working repeat: dots represent stitches knitting, blank squares needles in hold for each individual segment

For forming a straight edge at the sides of the finished piece, the first horizontal row of shells must start and end with half a repeat. Set up is on a multiple of 14 stitches. I began working with COR. Stitches are brought into hold consistently on the side opposite to the carriage, when 1 remains at top of half repeat (2 for full repeat), the remaining six of the recently worked repeat and subsequent 14 for the following repeat are pushed into work (21/22 sts), one row is knit across all needles, COL, the 7/8 remaining stitches from the previous group are brought out to hold, the carriage travels back to the opposite side once again on the grouping of 14 stitches, COR, holding pattern resumes opposite carriage, and from right to left. The contrasting color in the second horizontal row of shells begins on left, working on a full 14 stitch repeat, reversing the shaping. I am considering automating the process with slip stitch. The latter would have to occur on an electronic if repeat is to be used as-is since on a punchcard the width would need to be adjusted. If a brick repeat such as above is desired, two different cards or programmed repeats would need working out for the alternate shapes to occur on the same location on the needle bed after completion of each horizontal shell sequence.

It can be helpful to mark up a needle tape or even the needle bed with water-soluble markers to keep track of the repeat’s locations. I used a separate color for each repeat set. A bit of denatured alcohol on a lint-free cloth piece easily removes them. Markings on needle tape pertain to some of my other projects.

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.

HK pattern, software charting.

I have reached the point where decades old (89 and earlier) magazines that got “saved” are now being peeked at, and if not given away, then recycled. There may be some bleed through here from pages I have “saved” once again. Browsing through I found some designs not appropriate for machine knitting for one reason or another, but still creating interesting surfaces and the chance to explore using intwined’s other features. The program will create text from a chart, or chart from typed text with some limitations. One of the latter is a very large cable as seen in the attached document. PDF exports can happen within the program if one is specific in the sequencing of creating its documents. The 1989 pattern had only text for the repeat; I typed it, and had the chart pretty much created for me except for the problem row 5. Here is the resulting Intwined created PDF with some of my comments: cable_diamond. The following is the graph I edited, with my illustration for the execution of row 5

the blue line separates the slip stitch section, which can serve as a border on each side of the cable panels, the red lines the edges of the 12 stitches involved in the cable. The green stitches are put on a cable needle and brought to the front of the work, the next 6 stitches are knit first, then the ones from the cable needle to complete the crossing.

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.

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.

Chain cable HK experiment

Several months ago menswear began to appear featuring versions of chained cables. There are some published sources for such patterns, some available for purchase online ie in Ravelry,  while others may be found in the Barbara Walker Treasury Books. One HK version from the latter may be found here. I decided to play with excel and experiment further. I used Aire River Design font (no longer available) on my Mac to generate the symbols used. Columns and rows may be easily edited to adjust the height and width of repeat to suit the design process. I charted only knit “right side rows”. On purl rows, one simply reverses the previous row’s purl/knit sequences

the first linear repeat (outlined in orange)

I tend to prefer brick repeats in odd numbers across the piece: this instance adds reverse knit rows in the center of the cables as well for more surface texture, seed stitch may be another consideration

Slip/ tuck stitch experiments

These scarves were designed using the same method as described for mazes and mosaics, they are knit in rayon chenille, fringes are composed of  i_cords applied to cast on and bound off edges. The smaller shape/repeat allows for more control over fabric width while retaining full repeats

blue ovals: 11X58 inches excluding 3 inch fringe

BW: 9.5 X 58 inches excluding 4.5 inch fringe

Mosaics and mazes: machine knits_ from design to pattern

Maze patterns have long vertical and horizontal lines broken by regular gaps and the pattern lines change course from the vertical to horizontal, and vice versa. Maze cards can be identified by completely punched sections, some alternating with every other square marked for two rows, usually geometrically shaped. Areas of stocking stitch produce horizontal colored stripes, and alternating pattern stitches that slip or tuck cause the vertical stripes, which are sometimes pulled nearly diagonal by the influence of tuck or slip. The fabric will be unbalanced because the number of needles slipping or tucking will not be the same on every row. Odd rows form 2 color horizontal stripes, even rows vertical stripes, with color changes occurring every 2 rows.

Mosaics have a brick arrangement (tessellae), with clear perimeters and cores, and stepped diagonals (frets) that are partially formed bricks, their positive and negative spaces are created by the use of contrasting colors. The stripe sequence is not as obvious. The punchcard looks even less like the original design.

In single bed work, the reverse of the fabric will show the original design in the texture of its slip or tuck stitches. There usually will be no floats longer than one or two stitches.

The knit side may look like a fair isle but the back lacks the usual long floats, hence the name “float-less fair isle”

The row gauge is compressed. Tuck fabrics are short and fat, slip ones tend to be short and thin. Some patterns elongate in washing. The tension used is usually one number higher or more than that used for stocking stitch for slip patterns to reduce their narrowing, tuck patterns may also have to be adjusted to suit. Smooth yarns in contrasting colors are the easiest to establish and test the pattern, then the choices can be far more personal.

Designing your own: traditional “rules”

  1. if scale matters consider that the height of 2 rows may equal the width of one stitch
  2. start small, let each square on your graph whether on graph paper, in a design program or spreadsheet/vector program cell equal one stitch, each line on the graph represents 2 rows of knitting, when knitting the pattern double-length specific to KM may be used. The unfilled squares represent the lighter color/color1, the colored squares represent the dark/color2
  3. no more than one stitch to tuck, two to slip at a time
  4. row 1 and all odd-numbered rows (most stitches knit) can have any number of squares marked, the slipped (tuck, or slip/part tuck in alternating directions) are represented by blank grids (no more than 2 side by side for slip, single for tuck), they are generally knit in the lighter color/color1
  5. even-numbered rows must have single squares marked, they are generally knit in the darker color/color 2, there should be no more than 2 “light squares”/ unpunched holes side by side, the slipped (tuck or part/slip tuck in alternating directions) are represented by marked grids
  6. vertical lines must begin and end on odd-numbered rows
  7. vertical lines must always consist of an odd number of rows in total
  8. the finished design must be an even number of rows to allow for traveling back and forth to the color changer for picking up and carrying the subsequent color
  9. if the design is not to be elongated check to see that every light square to be worked in the dark color is present in the row below, that every dark square in the row to be worked in the light color is also present in the row below

Susanna’s chapter on mosaics has information on fabrics where “rules” get broken. Changing the order of the colors or introducing a third color may yield pleasant surprises. Knitting is started on a non-patterning row with first-row selection toward the color changer in Japanese machines. If you have a machine that preselects needles: color must always change when the needle selection changes. Four movements of the carriage are required to produce two rows of knitting.

One approach with a design that breaks rules:

masking alternate rows and “separating them”: odd rows knitting in color 1

dark squares get punched out/ drawn, light ones tuck or slip depending on cam settings

color 2 knitting even rows:

light squares are punched out/drawn and will knit, dark squares ones tuck or slip depending on cam settings

colored areas below are those to be punched overall

I used Excel to eliminate yellow fill on odd rows, darker fill on even. Many articles on this subject date back to graph paper, pencil, and eraser days. Quick color fills including empty make the process quicker with software. Still finding the image above confusing, it may be easier to decide what to draw on the card/mylar if all areas to be punched are dark, blank squares can then be more easily identified and marked, punching everything else or coloring them in and using color reverse if your machine has that ability. In the image below the lighter color is replaced by a darker one

the resulting card, which needs to be elongated X2

The swatches were knit using both the slip and tuck settings (also breaking the usual rule). Some of the tuck rows have a bit of color scrambling likely due to the amount of side by side tuck loops in the repeat not knitting off properly in those spots

slip stitch front

the back

tuck front shows the repeating trouble spots

tuck back

point grids for developing designs are of 2 types

in turn, the pattern may be drawn over them

staggered units may require some cleanup and “erasing”, as represented by pink squares

when the shape is what one desires, color separation follows as for the design at beginning of the post

Susanna Lewis at one time did publish a technique that could be entered in the E6000 that essentially did the separation; wincrea does not presently download techniques, there are other programs that can, and/or a combination of card reader sheet and computer download may be used, but that is for another day.

Mosaics and mazes from “FI” “universal” patterns

Many punchcards that obey the usual restrictions for tuck, in particular, may be used to create “random” mazes and mosaics, with color changes happening every two rows. Test swatches will show differences in surface texture, patterning, width, and height of the knit. It is useful to use clearly contrasting colors to study how the structure of the fabric is affected by different techniques. This test series explores the quality of the stitches created, along with using different knit carriage cam settings, although this repeat does not produce designs typical of either mosaics or mazes.
The swatches were knit during a class demo, for easy visibility, not as studies for finished garments or accessories. They were produced on Brother punchcard KM, using a single bed color changer. Electronic KMs advance a row for each pass of the carriage regardless of its beginning position/side. As noted in later blog post shares, such fabrics are produced more quickly and easily if an electronic is available with  2 compatible carriages for use.
Yet another single color variation, missing here, would be to use opposing buttons for tuck/slip.
The first preselection row is toward the color changer.  The FI pattern front with a bit of bleed-through where floats were hung up on the purl side

tuck 1 color slip 1 color  tuck 2 colors slip 2 colors  last but not least, slip stitch adding a third color front, still changing colors every 2 rows

This is a factory punchcard design, a smaller repeat. The repeat enlarged and punched for use in the pictured samples

Working out the kinks in my drop stitch lace saga

Still geared up for accessories, I felt compelled to come up with an edging: the following is an end stitch release knit. Prior to binding off the “tape” end stitches are transferred to the knitting bed, and then they and the remaining stitches are bound off. The transferred stitches do not drop and create a long stitch double knit segment. I am still working with the white acrylic
bound off and before release with the release starting after release
after pressing: flat, edge stitches too short attached to back bed before knitting pattern  (purl side)knit side alpaca and silk swatch, surprise: this baby knits up/steams fairly flat! The most regular dropped stitches happened when the stitch ditcher was used at least as frequently as every 4 rows, the lock was too hard to push with it resting on the knitting bed before each pass. I thought I might break down and use a built-in technique and my color changer to drop stitches: Technique 256 here I come, and figlet! this is a completely different fabric and there is one row of loops formed for every 4 passes of the lock I now get why some people call drop stitch with this technique mock garter stitch, but that is so not what I was going for, so back to the drawing board for me! I have an idea….
if the repeat is twice as long, and 2 of the 4 rows are knit without yarn, then loops created on the first 2 rows should in theory be dropped. Tech 130 in essence doubles repeat length. Using it and the same back bed pusher arrangement and settings as tech 256 the fabric is much more like the original, but tension now needs to be adjusted, denser knit stitches are now too loose… time for a very long break! you can’t always get what you want, do you sometimes get what you need? Curses! triple the number of stitches and tension problems occur, stitches don’t want to drop in specific areas of knit, now using a combination of empty lock and occasional hand ditching, different yarn, totally different look fabric than on the first sample: here it is on the machine
this shows why any lace needs blocking. Finishing on the Brother: bottom and top of ruffle rehung and cast off around 2 gate-pegs for length matching width of “pleats”; piece and “ruffles” also rehung for the same type of join after 1 row of knitting through both layers. The finished piece measuring 17X60 inches after partial blocking.  A different stitch pattern (E6000 1130) in the white acrylic color striping in the alpaca/silk blend, requiring dealing with yarn ends at color changer side. I had an interesting experience while knitting the one above of both locks jamming in the color changer. So many ways to have fun! and … I still want some bubbles!
A thicker yarn, larger tension difference between the locks, a bit more bubble on the knit side, but  too  much effort to knit
