Lace punchcards meet Ayab

1/8/18 It appears I now have acquired preselection from left to right on the first pass with my Ayab software, which I have been told is its “normal”. I am revising the information I have offered since I began working with Ayab if needed because of this, beginning with lace. This punchcard design is worked with each carriage operating for 2 rows, and all transfers in the same direction. The LC (lace carriage) on left, the KC (knit carriage) on right. An added note: sometimes punchcard designs may be used as provided, not altering the repeat in any way. Accidentally marking squares or pixels in the wrong spot, or deliberately starting with the LC on the wrong side, may still produce interesting fabrics. As always keeping good notes is more than well worth it. punchcard actions: transfers are all to the left (seen leaning to right on the knit side)With the first preselection row using Ayab beginning with the LC on the left, the same transfer sequences occur as in the punchcard machine or a single repeat on a mylar

swatch knit with the LC operating on the left, the KC on right throughout

For use with the color changer, the same repeat may be used. Transfers, however, now need to occur with the LC operating on the right giving the knit carriage the opportunity to travel to and from the color changer in 2 (or more, even #) row sequences. Using a punchcard, one would turn a punchcard over before inserting it into the card reader to work with the LC beginning on and continuing from the right. To achieve the same fabric using Ayab, shift the top row to the bottom of the repeat, and either mirror your image prior to importing it into Ayab, or use its mirror action in the pull-down menu. The chart shows the repeat prior to mirroring, with desired actions described to its right. It is not possible to read the first row from beyond the right set line using Ayab, so the LC begins on the left, travels to the right on the first blank row, selects on the second pass to the left, transfers stitches as it travels to the right again and stays there, operating from that side for the remainder of the knit. All transfers are now reversed and made to the right, and seen leaning to left on the knit side of the fabric. After the first 3 LC passes, each carriage operates for 2 rows at a time, all transfers are to the right, lean to the left on the knit side of the fabric.

Possible striping choices:  the differences between areas marked A or B is in the location of the color change. In A areas the color is changed immediately after the single transfer at the top of the “triangle”, in B areas the last eyelet is completed in the same color used up to that point, and the color change is made after the first row of 4 transfers at the base of the “triangle”. More complex lace repeats create much more interesting variations in the direction and movement of the stripes.

for full details. The punchcard was originally designed for operating both the knit and the LC carriages from the right. If KC I is used resulting in end needle selection on only the first and last needles in use, prior to passes of the LC push those needles back to B. If there are 3 empty needles on the edge on either side on rows preselected for weaving, bring the outside needle to work/ E prior to laying in the weaving yarn.  The image tiled for the width of my knit, in this case, 32 stitches, a multiple of 8I actually cast on an extra stitch on each side at the beginning of the piece with the intent they not be in pattern and create a single knit stitch border in areas of transfers. Here are the results, barring a couple of spots the weaving yarn did not get caught properly. The pattern as drawn produces a fabric that is interesting, but different than the intended With the pattern flipped horizontally / mirrored, we now have the same results as in using the 589 punchcard

So to mirror or not to mirror? that is the question… I tested  643 and 650 from Pattern book #5, found mirroring was indeed required for transfer accuracy. I  verified that the “triangles” do not need to be mirrored to match the punchcard swatch. The notable difference in the latter is that all transfers are in the same direction and that each carriage operates for only 2 rows.

12/28/17: tuck lace meets hand technique 

For more lace samples and symbols and suggestions from punchcard books on knitting the fabric, please see punch-card-book-symbols-and-samples

A Fair isle sample with deliberately mirrored lettering proved the program knits what it sees, so my letters were still reversed, as drawn.

On 12/25/17 I shared my first try at lace using Ayab and the workaround for the first pre-selection row occurring from left to right. The LC is the one to select for transfers, the KC knits to complete the formation of stitches. Brother punchcards for lace usually begin with selection rows, end with 2 blank rows at their top. Because Ayab requires a first pass from left to right for the next row to be selected, to get the pattern to work one needs to split the 2 rows at the top, bringing one of them down to the start of the repeat. If knitting continues with the LC pattern as originally drawn, the transfers will occur in the opposite direction of that intended. To work around that, the image may be mirrored in the paint program before download, or use action/mirror in the Ayab menu before knitting. One nice added feature is that blank rows may be left at both sides, creating a knit stitch border, and eliminating the problem of paying attention as to whether end needles are selected or not, and what measures to take. This fabric creates large eyelets, there will be 2 empty needles side by side for the duration. Some of the old pattern books referred to it as one of the “mock crochet” ones. These repeats do not hold with first-pass preselection from the left.

“Crochet” meets machine knitting techniques: tuck lace trims or fabrics 2

There have been several previous posts on “crochet” like stitches and “tuck lace”, this is another variant. The needles need to be arranged as in the diagrams below. After the first preselection row, the carriage is set to tuck

the full punchcard T= areas where tuck loops will occur, K = knit columns, o = NOOW, the red line the 0 mark on the needle tape

Every 5 rows, after the tuck loops are knit together (illustrated in repeats on far left), the formed stitch (single black square) is transferred in turn to the right and then to left; this works out happily so that transfers may always be made toward the knit carriage.
The sole repeat (all that would be required on a mylar) is 4 stitches wide, 5 rows high. The number of needles used needs to be planned so that there is a knit stitch on either end of the piece. This is accomplished by using a repeated multiple of 4 + 1, so one side of the 0 mark has an even number of stitches, the other an odd (4+1=5). Ayab software requires that the repeat is programmed across the width of the fabric, so the final design would be a variant of this, my sample was worked on 20 left, 17 right. Non selected needles form tuck loops until they are knit together every 5th row

If you prefer to work with the top repeat programmed, then transfers will need to be made on each side of the non-selected needles to get the proper configuration. If programmed with the bottom repeat, then and every other needle cast on is fine. I generally stay away from combs and weights if I can, but this is a fabric that benefits by evenly distributed weight, a cast-on comb with weights added to it is a good idea. In the absence of any, start with waste yarn and ravel cord, thread a thin knitting needle or wire through the knit, and hang evenly spaced weights on that. Follow with your preferred cast on, and knitting in pattern.

Combining knit carriage needle selection with racking

4/23/18:  inspiration source is from a Russian pin, bottom left #198

The first swatch, produced with manual selection, and varying the number of rows between racking to establish yarn tolerance

There are single rows of knitting on both beds, so the option of using 2 knit carriages is out of the running. My test swatch had the main bed doing all the knitting, the ribber knitting the joining segments with manual changes in its buttons from slip to knit and back when appropriate. The staring needle arrangement, on “graph paper”, and the subsequent racking positions: the top illustration is for racking position 4, the bottom for racking position 0.A tentative plan of attack: the combined knit and ribber carriages are to be used throughout. The main bed KC is set to knit, but the change knob is set to KCII. The blank squares will actually knit thanks to the setting, the selected needles will indicate the direction in which racking is due to take place prior to knitting the next row. 

This is the starting ayab repeat, with single repeat segments highlighted (one alone would be adequate for most other electronics). 

You will be working on the purl side of the knit. In what is an increasingly irksome feature to me, Ayab will automatically mirror horizontally any loaded image, so to get the above, you need to actually be either mirroring the image prior to loading it (my preference), or remember to do so through Ayab’s actions after.  Enter this, the ayab screen shows this 

This is what appears on the left side of the Brother ribber. I prefer to rely on other methods to track directions and numbers of positions in racking, but the ribber itself provides some clues. My pitch lever will not move all the way to H, but that is made up for in the ribber adjustments, so it is not a problem. A reminder: turning the racking handle to the left is toward increasing numbers on the indicator, to the right is toward decreasing numbers  The set up for my swatches, and the first row knit on racking position 0.  

The first preselection row in Ayab knits above needles on both beds. With carriage on the right, set the ribber to slip <–  –>, and knit up to the next row where needle pre-selection appears. *Change the ribber button on the side to match the direction in which you will be moving the carriage (left if knitting to left, right if knitting to right) to knit from the slip setting, knit to the opposite side (no more needle selection), change ribber lever back to slip again prior to any more knitting.** Repeat * to **. Position 4:

I began to run into issues with ribber stitches being too tight, this was knit with a tension adjustment, resulting in a less defined texture

Going a different route: another repeat, with each position, repeated once, repeat is pre mirrored  
a swatch with the racking happening only in the center of needles in work

Starting position can be variable. With more stitches cast on, while keeping the same ribber configuration, racking can happen further to the right or to the left. There need to be enough stitches on the main bed so ribber needles do not travel beyond them when racked. The knit bed uses tension close to that used for stocking stitch. The ribber stitch size may need to be adjusted to allow for a wider move toward either side. A looser ribber tension results in a less sculptural surface on the knit side. I have seldom been able to knit more than 6 rows on the main bed with ribber combination stitches on Brother, often maxing out at 4 depending on the yarn. Consistent habits help develop one’s own most meaningful reminders for taking action.

5/12/18 2 more samples. This time racking is done by 3 positions, the ribber setup is with 3 needles out of work, and 5 in work. Set up is with the racking handle on 3, move to and from positions 0 to 3. Knit 4 rows single bed. Rack to the next position. Use ribber set to knit for 2 rows for the sample on left, for a single row for the sample on the right

My step-by-step interpretation, which may be worked as a hand technique on any machine 
1. racking handle on 0, cast on for every needle rib
2. transfer stitches to the main bed to match the needle arrangement above, and knit 3 rounds
3. set the ribber to slip in both directions, knit 3 rounds
4. rack 4 to the left, set the ribber to knit, knit 3 rounds
5. set the ribber to slip in both directions, knit 3 rounds
6. rack 4 to the right, set the ribber to knit, knit 3 rounds*
repeat steps 3-6

I have worked with racking in the past but never attempted to have racked shapes interacting with single bed patterning across the width of the piece on the KM. My 910 is presently connected to a Mac via the EMS Ayab kit. Sampling is quick and easy, replacing the mylar. One critical difference is that the repeat used must match the pattern in width numbering the same as the needles in use for the piece, so at least for testing my initial repeats were 30 stitches wide.

I find trying to chart things out before I actually knit helps me plan and understand what actions I need to take. Mac Numbers is my go-to for charts for the moment.  Here a random slip stitch pattern is put on a knit ground that takes into consideration possible racking positions, with the ideal position for reversing the bend at the center of the chevron pattern. With a bit of planning, punchcard markings or even mylar ones may be used to help with tracking racking numbers for accuracy, but that appears lost using Ayab software

When planning for racking within the width of a piece, the racked columns will extend beyond the vertical edges of the knit. Since this is not about having zigzag edges but keeping the design within the body of the knit, the starting point and spacing for your ribbed stitches matter. Brother racking handle is numbered from 0 to 10. The numbering and direction of movement vary between KM brands. If you begin at 0, you are only allowed to move the ribber to the left, if at 10 the ribber only moves to the right. So that said, the racking sequence in the above illustration should be reversed, traveling from 10 to 0, and back. The green squares represent the direction in which the ribber stitches are moving, and the numbers in the column on the right represent racking handle positions. 

I found this slip stitch repeat produced too little detail in my swatches, but were it reduced for mylar use, it would remain 7 stitches high. It was taken from a punchcard book, so black squares/punched holes represent knit stitches. To match the fabric, in mylar use, the color reverse would do the job. The Ayab kit bypasses both the mylar reader and the programming capacity of the buttons on the left, so double height, double width, color reverse, etc. including the DBJ setting are planned for in the file import into the software. In some instances, Ayab settings (ribber for DBJ, and “circular”) do the work for you. I am using GIMP to create my BMPs. Paintbrush is a free program, still available for Mac, and functional including in High Sierra. It is the program used by some forum members to create their repeats, providing an easy alternative for people who not be used to working with image editing programs.

the slip stitch repeat in its original state: because slipped stitches create their texture on the purl side of the fabric, images do not need to be mirrored for the direction of the texture to be matched using electronic machines 
If the goal is to have the machine take care of keeping track of knit rows for you, without having to make changes in cam buttons, in the mylar a single repeat with blank squares programmed at the top and/or bottom of the repeat could then be knit using color reverse. Here the situation is similar to that of punchcard users who need to punch a hole for every knit stitch but considerably faster. If the original pattern is satisfactory,  planning for all knit rows as automatic needle selection can be done by color reversing the pattern in the software and adding all black rows in the image for download.  
some other all-over variations to try, individually, or even sequentially for slip stitch all-over texture

the first tests, for the various slip stitches, nothing quite “there” yet  
this is getting closer to the goal

The above working repeat and all above swatches were knit with the first preselection row from right to left, not left to right. For these stitches, the starting side does not make a difference. If the pattern, however, was in blocks that were even-numbered in height (2, 4, 6, 8), and the color changer needs to come into play for striping using it, accommodations need to be made so that preselection for row 1 happens from the right side to the left, toward the changer. The programming needs to be set to begin on the very last row, so the repeat returns to row one for preselection from right to left, and knitting rows 1, 2, etc begin with the KC set to appropriate cam buttons, to and from the left side of the KM.

The racking sequence needs to be adjusted to have the points of the zigzag land in the center of both the slip stitch areas and those in plain knit if that is the goal.  I am encountering needle selection issues with my hack, so this fabric is getting put to bed for the moment. In principle, the black squares in the illustration represent knit rows, and their number is easily enough adjusted in height. Punchcard users would need to punch holes for each black square, mylar users can fill in the white squares for a single repeat, add blank rows at the top or bottom, and color reverse when programming. In Ayab software, the repeat has to be drawn for the width of the piece but will repeat “infinitely” in length.

This is a possible punchcard template, with a shorter racking sequence. The Numbered column on left indicates the racking position. Pattern rows are preselected, so racking occurs prior to knitting across each row. I am also in need of purchasing more punchcards or another roll, so there is no test swatch at this moment. The top and bottom rows of punched holes on the colored ground are not part of the repeat, they overlap the first and last 2 rows of design in the punchcard, allowing the pattern to repeat in length. Ascending numbers swing to the left, descending to the right. Rows may be added at the level of #7 (7, 8, 9, 8, 7), so that the center of the swing may then occur on #9 positions in the racking handle, lengthen the card accordingly.5/14/20
Electronic machine models make experimenting easy and quick. Here an all-over tuck stitch is programmed for the base fabric, and racking variations are considered with the goal to cross the base fabric at various points in the patterned areas, or within the knit space alone. With increasing racking indicator numbers the ribber moves to the right, the shape its stitches create on the main bed moves to the left. With decreased racking indicator numbers the ribber moves to the left, the shape its stitches create on the main bed moves to the right. The repeat required mirroring for use in my electronic 930. Experimenting with racking intersecting tuck stitch on multiple repeat png, stitches were picked up on the ribber aside from the first tuck stitch on the right, A, on the center, B, and on the left, C, of the knit stitch groups.

 The tuck pattern tested, racking placed in the center position changing ribber needle positions
moving toward positioning the racked pattern further into the knit columns. Making the knit columns wider, placing repeats differently. The intended placement of the racked pattern is shown in yellow. Good notes and documentation of the final needle arrangement will make the technique easily reproducible. The needles involved on the top bed always need to be returned to the patterning position after any shares. At any point in the knitting, it is easy enough to transfer stitches on the ribber up to the main bed, drop the ribber down, and check on the placement of the racked pattern. If the place is satisfactory, the moved stitches can be returned to the ribber and the work is continued. If not, transferred stitches can be left on the main bed, other stitches can be shared with the ribber and patterning can continue with racking in the new location. One such adjustment is seen toward the bottom of this swatch. 

Revisiting drop / release stitch lace 1

Hand knitters may be familiar with drop-stitch patterns where the yarn is wrapped multiple times around the knitting needle, followed by knit stitch(es). On the next row, when the wrap is reached, the extra wraps are dropped off the needle, and the remaining single loop is knit in a regular manner. On the knitting machine this technique is called drive and mesh lace, release stitch or summer fair isle by Passap, and drop stitch lace in some of the pattern books. Drive lace typically has lines of patterning where loops are formed between rows of all knit stitches. The main fabric, stockinette, is knitted and produced by either bed. Selected needles knit pattern stitches on the other bed for one or more rows, then are dropped from those needles, unraveling back to their starting point, creating the larger, open stitches. Sometimes a distinction is made between terms used, in drive lace the bulk of the punchcard is left blank, and there are far fewer marks than in drive lace. In mesh lace the balance of holes to punched or blank areas is 50/50 or more punched areas than blanks, often the “holes” or black squares are side-by-side.
Drive lace marks out the shape of the pattern, mesh forms the background. Blank rows across the width of the repeat allow the knitting of plain rows between dropped stitches including ones, separating the series of holes, or stabilizing the fabric.
Both types of mesh may be combined in the same fabric, with dropping planned on the same rows. The diamond on the left represents drive lace, and the one on the right is a mesh version. On the right, solid “lines” echo the shape. Repeat is suitable for punch cards but may be altered to suit both cards and electronics. revised with fewer single dots, and solid lines in the ground The fabric may be created both as a hand technique or using automated patterning. In sources that show loops being formed on the ribber, stitches are released by uncoupling the ribber carriage and moving it across the knitting and then back to its original spot, thus dropping the stitches. In Studio machines the P carriage may be used to drop stitches, see previous posts on modifying one for use on Brother KM.
The tension setting on the patterning bed affects the loop size and its tension is frequently one to three numbers looser than the all-knit bed tension. In Brother machines, the ribber knits at a tighter gauge than the main bed, so take that into consideration and adjust it when knitting all knit rows on every needle on the ribber, where the tension may need to be loosened one or more numbers than when knitting same yarn in stocking stitch on the main bed. Matching tension numbers on both beds may provide enough of a difference in stitch size for loop formation. The difference in gauge between the beds also merits calculating adjustments when knitting in circular or U format.
Releasing stitches may happen after every pattern row, after groups of pattern rows (such as bubbles or check patterns), or even at times when knitting is completed. With groups of pattern rows, I have had better results with more frequent stitch releases. Two types of mesh can be created. Stockinette mesh has an equal number of rows on both beds. The result is enlarged stocking stitches along with narrower, single-bed ones on any one row. Half Milano mesh has a horizontal ridge on the purl side with 2 rows knit on the all-knit fabric bed, to every one row on the patterning bed. One of the rows has the patterning bed slip every needle, with the ribber only knitting, the second row forms the combination size stitches as discussed previously. In patterning in Brother KMs, this would need to have such rows added to the programmed design. The fabric is a bit more “stable”. Passap offers multiple techniques for dropping stitches, often referred to as summer fair isle, and using 2 colors per row. Different looks are achieved by changing the built-in technique number, as well as when using a stitch ditcher on every row knit, as opposed to using empty passes of locks to drop the stitches.

Working with positive and negative space variations: the repeat is suitable for any machine, my sample is executed on Brother KM. Since alternate, all blank rows have no needle selection, before knitting that row (ribber only will knit), dropping stitches knit on the main bed on the previous row will not alter the pattern using any method you prefer, set up knitting so all stitches are on the ribber. If you prefer to set up complete repeats prior to watching, “air knitting” prior to ribber set up or using the position option on the main bed if that is available, will help achieve that set knit carriage to KC II (used when patterning does not occur on every needle across the needle bed), both part buttons pushed in for free pass to the opposite side of km, no knitting occurs but the first row of pattern knitting is selected. Ribber is set to N<–> throughout the carriages now move to the opposite side, selected needles on the main bed pick up loops, and nonselected needles stay empty. Ribber knits every stitch using a ribber cast on comb, stitch “dumper”, or another tool, move needles holding stitches forward to drop loops, and return empty needles to work position (B)as carriages move to the opposite side, needles are selected for next row of knit stitches to be knit on main bed carriages now move to the opposite side, loops are picked up on selected needles all needles are now not selected, above stitches/ loops are dropped, needles are returned to B position before the next carriages’ pass carriages move to the opposite side, selecting pattern needles carriages move to the opposite side, picking up loops before carriages move again, drop stitches formed. Watch loops after they are dropped, if tugging knitting it is not enough to pull them out of the way of needles returning to patterning, take a tool, or something like a credit card. Slide it from one side to the other between the beds, thus keeping loops clear away from the main bed

In summary; assuming one is starting on the right side of the machine COR
step 1. <-  the carriages select needles that will form loops
step 2. ->  the carriages knit, picking up loops
step 3. drop the loops just formed, returning all empty needles to the B position
step 4+ repeat 1-3 for the entire length of the piece
My sample was knit in slightly fuzzy wool. Smooth, thinner yarns result in longer stitches whose patterns get read more easily. Because wool has “memory” the vertical edges tend to roll to the purl side and return to rolling even after heavy pressing and steaming. There are a couple of spots where no long stitch was created due to markings on the mylar not being dark enough.
Other things to consider: this fabric widens when blocked, so cast on, bind off, and beginning and ending edges need to accommodate that. This particular design creates a fairly balanced fabric. In many drop-stitch fabrics, it is recommended that edges contain stitches dropped in the pattern in order to maintain vertical length at the edges. To achieve that, the first and last needles on both sides should be on the main bed. That said, having an all-knit border (stitches knitting only on ribber, no dropped stitches) may work well in your pattern, or pull edges in too tightly when compared to the all-over motif released repeats. Testing on your swatch can be achieved easily by simply taking some needles on the main bed out of work on one side, thus creating the “all-knit border”. The latter can happen by accident if not all needles are returned to the B position properly after dropping stitches.

It is possible to produce a drop stitch pattern on the bulky machine or depending on the yarn, knit with heavier yarn on EON on the standard machine. The resulting “patterns” happen with varying the number of rows used to knit in each color, which has not been addressed in previous posts. I prefer to use patterning on the top bed to select needles, but this pattern may also be knit as a hand technique, using the ribber to produce the loops that will be dropped. This page from the ribber techniques book reviews the baseline process and settings

purl side is shown first for each segment, followed by its knit

Punchcard knitters are not excluded from creating these fabrics. Some punchcard sets supplied with machine purchases were published for Silver Reed Machines, two such sets are available for download ie. Silver Reed-Singer R-2 Standard Punchcards For SR360 Ribber and the same in a 30 stitch version making them suitable Silver Reed-Singer FRP70 30 Stitch Ribber Punchcards. One such card easily translates to one color drop stitch. Changing fiber content affects the scale of resulting patterns and the size of the dropped stitches, the yellow sample was knit using a wool rayon, and the purple cotton used the same tensions. If using punchcard machines, factory issue punch cards provided with the KM may be usedPlaiting is also possible, but depending on the color choice the pattern may become muddied A slip stitch edge may be planned to keep edges of items such as scarves from rolling consider top and bottom edgings that include the technique (illustrated in the previous post) Adding complexity: dropped stitches may be combined with other stitch types, shown here in combination with tuck stitch on the main bed, dropped loops created on the ribber. Stitches are transferred up to the top bed. The KC is set to tuck, the ribber episodically picks up loops across the whole row, and they are dropped on the following pass; it is then set to slip when the main bed is returned to tucking An alternative way to produce this fabric on Brother is to use the knit carriage with no yarn to do the “stitch ditching”. The basic design programmed into any brother machine, electronic or punchcard will need to be altered. The intended design in my sample is a 4 X 4 square, colors represent what would be punched holes, black squares, or pixels. Simple block patterns such as these may be released upon completion of each “square” series, in this case, after 4-row segments. Two rows are added at the top of each “square”, one repeating the motif width, the next completely free of any markings Rows 5 and 6, 11, and 12 are not part of the original repeat. The 5th design row provides needle selection, traveling from right to left. When the carriage passes in turn from left to right with no yarn, those preselected needles will drop while preselecting a blank design row (6) that allows the carriage to return to the left-hand side. As it moves back to the left, the carriage will preselect the first row of the design. With COL yarn is picked up in order to knit the next set of dropped stitches. A color change may be made while the carriage is on the left.
Begin with all stitches transferred and in the work position on the ribber only. Every needle will be in work on both beds for the remaining fabric. The ribber half-pitch lever is on H. With COR set the change knob to KC, preselecting from right to left for the first row to be knit after pushing both part buttons. This allows the KC to travel to the left without forming any loops or stitches, but the preselecting first row of the pattern. Change color if using more than one color, knit 4 rows. color 3 (or 2) can be an empty feeder. Change to color empty so yarn(s) in use are held until picked up again and there is no yarn in the ribbers sinker plate yarn feeder. There are 2 options for dropping stitches. One is to disengage the KC from the ribber, it will be picked up again as you move into the color changer to pick up the yarn once more. The other is to keep the carriages paired, set the ribber to slip for 2 rows, then back to knit as you return to the color changer, pick up the yarn again, and continue to knit. If row count is important ie in making a garment, the row counter gets turned off for the 2 rows when stitches are dropped, remember to turn it back on when knitting the next 4 pattern rows. I personally find this fussier and more error-prone than other methods I have described. My swatch is knit in acrylic thin yarns and lightly steamed, so bubbles have flattened out considerably. The fabric is related to that shown in the ribber techniques book, page 23, created by picking loops up from the ribber combined with racking.
This is my ayab repeat, this time executed by configuring the knitting to begin on the last pattern row 16 for that first preselection row from left to right instead of altering the repeat itself More to try: the typical appearance to look for in the source inspiration is that of single-row horizontal geometric designs with all blank rows separating them from each other.
Studio pile knitting patterns such as those found in may be used as published. It may be worth color inverting or spacing out the designs with many more white squares in between the motifs for more recognizable designs in the dropped stitch areas and for a more stable fabric in repeats such as these. On rows where there are no punched holes, resulting in no preselection in Brother machines, stitches are dropped prior to moving the carriage for preselection of the next row of patterning. The results are easy to test and amend. One such pattern: the original repeat The yarn used here was a softly spun rayon that began eventually to split, and get partially caught up on gate pegs, leading to the ending of the swatch Switching yarns made knitting easier and quicker to produce, planning for a different sort of wave, an amended version of the original design was used Fair Isle
a 24X60 design repeat was randomly chosen and used double length The first pattern row will pick up loops on the top bed, using any tool, drop the loops and return empty needles to the B position.
The next pass will drop the stitches and preselect the next row of loops.
Knit to the opposite side again picking up loops, drop them, return needles to B, repeating the steps.
The knit grows in length very quickly, the side edges and cast-on and bind-off methods would need more careful planning in a final project.  On electronic machines, the repeat can be adapted to yield more knit stitches between the flower forms
Beginning with a 23X31 isolated motif,  the shape is expanded to 30X36,   and two potential dispersals with the flower drawn in symmetric repeat in width and height X3  Transfer lace patterns: use patterns that have at least 2 rows knit between repeat segments. The results are likely to be subtle. On electronic machines: cast on as preferred, transfer MB stitches to ribber, where all stitches will be knit on every row. The main bed will be knitting the stitches that will be dropped, the lace carriage will not be used. As the carriage moves across the bed selected “lace” pattern needles will be knit, and the non-selected ones will be skipped. Program the pattern in the usual manner. Set the change knob to KC II to cancel end needle selection, the knit carriage to slip in both directions and continue knitting until all needles are in the B position. At that point disconnect the main bed and ribber carriages, unthread the yarn or have it held for you in the yarn changer. Set the main carriage to knit, move across needles in B, dropping them since no yarn is in use. Bring the disconnected carriage across the knitting again, reconnect to the ribber carriage, and rethread. Set KC to slip again, repeating the process. As an alternative for dropping stitches, leave KC set to slip, and push all needles out to hold. With no yarn in the feeder, any loops will be dropped. Make the 2 passes with KC only as described, reconnect carriages, rethread, and continue until no needles are selected again.
If on an electronic machine with 2 knit carriages available: the number of rows is usually an even number, so an additional knit carriage with no yarn could be positioned on the opposite side to the one selecting pattern, set to do plain knitting, holding no yarn, and it may be used to drop the stitches on “plain knit rows” on lace card without requiring the other additional steps and cam button changes.
Tuck and drop: use color reverse if appropriate (black squares for knit stitches, white for tuck) set up as for other drop stitch fabrics, choose patterns that are broken up by 2 rows of plain knitting between the tuck rows. KC II is used once again. Since in such cards, you one is working with punched holes or black squares, the empty knit carriage alone may be taken across with no yarn, dropping the complete, all knit rows. It is not necessary to change the knit carriage setting from tuck to knit to do so.
Tuck is an alternative option for a free pass as well, realizing that helps avoid errors in patterning by missing resetting the cam buttons between the two functions.
Racking patterns:  a few variations are suggested in Brother punchcard volumes. Sometimes translations are what can be described as interesting. One such pattern Yarn choice as always can make a good deal of difference, here a wool rayon was used. The zig-zags would be more visible if worked using a larger number of all-knit stitches

 

A lace mesh series: GIMP, superimposing, Brother 910

I like placing motifs, grounds, and borders myself whenever possible, in any knitting technique, rather than relying on adding or combining them via the built-in KM software.  It is simply my strong personal preference in designing and gives me additional controls over patterning. However, the ability to superimpose is a convenient feature, available on multiple machines and worth mentioning. I have used it more frequently in operating my Passap, than my Brother 910. That said, it would appear to be an easy feature to use for programming shapes onto mesh grounds. For illustration purposes, I am using a 24 stitch repeat. Electronics width and height potential depend on the use of mylar or PC download. The “rose” is not a workable, resolved repeat. When electronics were first introduced, at one point Kathleen Kinder wrote a book on electronic knitting (? 1984), exploring the full potential of managing designs by combining settings and flipping buttons for both the Brother 910 and the Studio 560.

A bit of review on machine buttons and functions for the Brother pattern case for those unfamiliar with it.  M= Memory: each of the tiny red spots on the garment representations lights up, as specs on motif are entered or reviewed. CE= cancel entry: corrects programmed numbers or cancels the red error light when it flashes. CR= cancel row: press in a number, say 2 on the panel, and the card moves back 2 rows. If you press the button and no number is entered, the error light flashes and the card stops advancing. This is the same as locking the punchcard to repeat a pattern row. RR= row return brings the card back to the set line. This is routinely done before shutting off the machine when knitting is complete or to remove the mylar for editing.  CF= card forward. The mylar returns to programmed design row 1.  Numbers pressed in using CR or CF do not change those programmed using the M button.

When the pattern selector button on the 910 is down, the pattern is centered on green #1. A reminder: Brother has 2 needle #1 positions, one on each side of 0. When the pattern has an even number of stitches, it will be centered with half that number of stitches divided evenly on each side of 0. For 24 stitches, the pattern’s limits are yellow 12 and green 12. If the repeat is an odd number of units wide, the center stitch then will be placed on green #1 (right of 0). If the repeat is 25 stitches wide, then the pattern limits are yellow 12 and green 13. If using a 24 stitch repeat, the machine automatically knows that the first needle position (FNP) for the pattern is yellow 12. When the pattern selector is in the upper position (motif A) and the middle position (motifs A & B) we can choose the FNP and with A & B the number of stitches separating them. One way to produce filet lace is to program A & B motifs. The lace mesh is the A motif, the “rose” the stocking stitch motif. The A motif can be on the left or right of the mylar, but it is always the taller of the 2. In most cases, it is the dominant pattern. The starting row for the combined motif is shared.

In lace knitting transfers and resulting eyelets are programmed as black squares. Superimposed solid patterns in stocking stitch occur in unmarked areas of the mylar or downloaded image, so they need to be “white squares”. In order to get the 2 to meet, the mesh repeat in the height required (column A in the illustration), and a single width is drawn or programmed in reverse (column B), with the result being read as (column C) when it is programmed as the base for a complete overlap. The basic mesh becomes the A motif in programming the 910, the stocking stitch “shape” is the B motif.  If end needles are selected during knitting, they need to be pushed back to B manually or use the orange L cams. It is possible in addition to mark the “L window” on mylar, but the mesh repeat is so regular you may not find that necessary.The “rose’ would also need to be drawn in black, and positioned or programmed, with first placement resulting in the image seen below right. The color reverse is then used converting white squares to black, and lace knitting could proceed based on the black markings resulting in eyelets.  As is already noted, there is no guarantee the image placement on the mesh the will yield a precise shape or the best possible results for motif edges, its definition, and its segments’ outline In terms of placement: if the all-over mesh is programmed centered on G1, and the motif is positioned with FNP other than G1, any simple, extra rows of mesh prior to starting the all-over pattern (below green line), will need to be programmed separately with adjustments also in FNP to match the superimposed segment. The programmed repeat for the mesh “rose” below would begin immediately above the blue line, and the extra mesh rows at the top would provide the transition to the start of the rose once again. The height of the pattern seen in the B column in the first illustration may be adjusted accordingly. 

Color reverse (button #6) will provide “black squares” for the creation of transfers to create eyelets. The mesh and superimposed design need to share the same starting row. The image above reversed shows extra white at the bottom of the chart that needs to be eliminated. Brother lace starts on a selection row (black squares), ends with 2 blank rows at the top of the pattern (white squares). This is reversed in Studio knitting.

What happens when starting row placement is the same for both motifs, and the color reverse is used: the first-row lace carriage selection is good to go. The height of the mesh above the rose may be adjusted to suit. Trying to place multiple roses in different locations on the finished piece using this method is more than my brain wants to even consider. Punchcard knitters are not completely out of the superimpose loop. If you are so inclined, areas on mesh punchcard ground may be taped over to test the repeat. Again, this works best for simple shapes. Tape may be shifted or trimmed as needed. If intended for extended use, trace holes over a blank card, punch the final version, and proceed. Images on punchcard machines are reversed on the stockinette side. If direction matters, flip the card over horizontally, mark and punch, or if the card is already punched, work with lace carriage on right, knit carriage on left. No worries about multiple programs or a mix of starting points, etc. Know the rules for where to begin and end for lace knitting.

Sharp single stitch points are not attainable. In the illustration below, the yellow indicates the “desired point”, red squares indicate the additional stitches knit, adding to the intended shape as the alternating directions transfers are completed. The one stitch start is actually converted to 3 stitches, 3 to 5, etc.Later model electronics included “stitch world” pattern books.  A usable mesh is # 103. Do not use 104, since it leaves 2 adjacent needles empty. If aspect ratio matters in the superimposed image, knit test swatches to determine gauge. Cell/ grid size may be set to knit proportions rather than square to make visualization of finished shape easier. The mesh created using 103 uses 6 pattern rows for each 4 knitted, so you must add those rows “ to the height of the overlay design. Similar adjustments are needed if other mesh repeats are used. Simply scaling the image may require some clean up as well before the motif can be placed on the ground design.

A lace mesh series: using GIMP

Eons ago I owned a BitKnitter for my Passap machine, and to this day I miss it and some of the other Cochenille software that is no longer available, especially when working with multiple colors for color separations of any sort. When using it for downloading the resulting motif, picking the same exact color for each “square” on the grid was a necessity for accuracy. If “only” black was involved, the same guide applied. Working in GIMP one can set the color mode to fewer colors to start with, reducing the palette. This can limit your editing ability sometimes, and switching between modes may be required. I tend to go autopilot when I work on color separations for any purpose and work with built-in colors rather than custom.

It is helpful to have previous experience with any program as well as with basic knitting before tackling and combining large scale designs and fabrics such as lace. This is not a step by step how to use GIMP (search for my other posts on the topic), merely an illustration of my experiment in working with superimposing an image onto a mesh grid.

To start with: a 1 X 1 grid is set up. “Black squares” become single pixels in downloads. For the single stitch 1 X 1 grid to be visible, I prefer to work in at least a 500X magnification. Because I do not own a hacked machine I am unable to provide a corresponding test swatch to the final chart.

The resulting image may be tiled to produce a large enough mesh ground, the grid needs to be turned off for this step

The tiled image will appear on a different part of the screen, shown in both versions below, I realized reviewing the above that the width was for more pixels than could be programmed on a 200 needle machine, I resized its width to 120 pixels

here the grid is removed for further processing 

the goal is to retain the black squares for the end bmp, so the ground is filled with a color that will later be removed gridded again if and when needed 

Today’s image is a letter (20 pixels by 24), produced in a new file with text from one of my built-in computer fonts. I happened to be working in RGB mode the same image as it would appear in indexed mode Here some edges “clean up” has been worked with the grid on, then removed for tripling the motif length (now 72 pixels) and pasting on the “mesh” ground 

Switching to indexed colors (6) if you have worked in RGB to this point, it may make cleaning up of edges easier.  I flood filled the A to insure only one red was in use. Below the A is selected (fuzzy selection tool) and copied for paste onto the “mesh”. Magnification reduction to 500X makes the whole file more easily viewed on my mac

the A pasted in placewhite color fill leaving only black squares of letter and ground

Superimposing may be used in some machines, but eliminates the choice of editing when one is “not happy with edges” until after sampling the knit, has several parameters and limitations. Above image gridded for editing:
feeling better, with the exception of the left side bottom of right leg of Aone last bit of clean up, switching between magnification  as needed happier grid removed, image magnification reduction to 100X for export as bmp and download to KM

When downloading a large image that constitutes the width of your piece, programming an extra square or 2 vertically for the height of the pattern in “white” on each side will insure that stitches in those areas are not selected for transfer by the lace carriage, and a knit border will be created.

Things become more complicated with more complex shapes. This is part of a filet crochet chart, and a rose now becomes my goal

use selection editor or fuzzy selectpaste and move to “best” spot not quite a rose

8/9/18. From the Brother electronic lace pattern book, worked out in a much larger repeat 

Back to the drawing board: the mesh and knitting method are altered. For a possible knitting method option see https://alessandrina.com/2017/07/28/unconventional-uses-for-punchcards-2-thread-lace-cards-for-filet-mesh/  The ground “mesh” is now composed of every other stitch, alternating every other row. The “rose is not lengthened. “Stitches” need to be “cleaned up” to approximate a more recognizable shape.

 When satisfied, export in format for download.

 

A new “leaf” lace

I am often surprised when I return to visiting past ideas and discover how long I have actually been blogging.
My temporary obsession with lace leaves began in 2011.
In 2016 Vogue knitting published what appeared to me to be an interesting pattern for a leaf lace variant combining dropped stitches and lace transfers.
Below, I am sharing my WIP swatches and notes.
I am presently working on some production knitwear pieces, and it is unclear when I will return to more samples of this variant.
The “new leaf” requires hand techniques and working with multiple transfer tools.
Dropped stitches in hand knitting can translate to ladders in a machine knit.
My first trial swatch was made on the standard KM.  Casting off and on posed interesting questions. The lines where knit stitches meet ladders, as pointed out in previous posts, can result in the knit stitches aside the ladder growing in size

I do not enjoy time-consuming hand techniques on the machine, so to speed things up I moved on to the bulky. As with any other knitting, the lengthwise sides of the knit are going to want to curl to the purl side. I deliberately worked with acrylic yarn, anticipating that blocking it would be required to attempt to get the results to stay flat. Here is the resulting swatch, as first off the KM

after pressing with steam 

A couple of days later the fabric was still lying flat, so I decided to try to chart it out for slightly different results while planning for a different turning angle and a consistent number of ladders throughout.

I began to use Excel 2008 in 2009, as well as Apple’s Pages and sometimes Numbers over time to produce my charts and illustrations. I keep learning tiny bits as time goes on. Some features may disappear in such programs or become added with upgrades. These are settings I prefer for backgrounds and borders in Excel

format

and for screen grabs or improved visibility, zoom comes in handy 

For links to some online tutorial by other authors https://alessandrina.com/2013/10/29/charting-knits-in-excel/, a search in my own blog will lead you to my own explorations over time. Simple graph paper and color pencils may be used if the software is not available to help work out proper repeats, etc. A single repeat of my leaves so far is shown in 2 segments for increased visibility, successful knitting, probably in another “killable yarn” tbd.

Return to circles, knit “pies” 3

Elizabeth Zimmermann provided guidelines for circular shawls in her books and publications, including “Knitting Workshop”. For a basic pi shawl (p. 112, Schoolhouse Press, 1984) the assumption is that each section is twice as deep as the previous section and has twice as many stitches. Below CO row represents cast on stitches if the work is to begin from the center out, Column A the row count on which the increases take place, column B the number of rows knit just prior to the increase row (A-1), and C the number of rows available for any planned repeat (A-2), these are constants. The columns directly below each cast on (CO) number (orange) counts represent the number of stitches when increases are complete. The stitch count doubles when the number of rounds has doubled. Mary Thomas’s Book of Knitting Patterns, Dover 1972, p.p. 245-247 provides guidelines for circular medallions. She calls her first a “disc” medallion. In executing it the aim is to scatter increases so they are less visible and do not form spokes. Four stitches are cast on, with 4 stitches increased in the total count every other row. The number of stitches between M1s increases by one on every other row. My chart happens to read from left to right. As with any knitting in the round, the process may be reversed, starting at the circumference and moving toward the center. I personally like charts to help visualize results, and have revised her counts in the illustration below so increases are at the same rate but placed a bit differently within the rows. On rows with even numbers between decreases, start row with half that number of knit stitches before the first increase. Because one is knitting in the round, with knit side facing, all rows are knit. If the work were knit on 2 needles, knitting every row would produce a garter stitch. what happens if increases “line up” For her circular “radiant” medallion after the first 2 rows increases are made every 4th round. My chart is renumbered excluding the first 2 rows, so the increase rounds would occur on numbers divisible by 4, making it easier for tracking them. Each “building” round increases the number of stitches by 16.

In her “target” circular medallion, the building increases are arranged in concentric circles. Each increase row begins with a M1. Once RC 20 is reached, a stitch is added between increases on each increase round. This chart reflects the knitting progress, but not the shape. STS column on right reflects the total number of stitches after increases have been made. Each building round after RC 6 increases the count by 32. Formulas for more, varied geometry-based medallions are also offered in the book.  I finally “discovered” actually using formulas in Excel! The video that clearly and quickly helped me learn how to: https://www.youtube.com/watch?v=QFVkSnGgZZclooking at the flow in table form for the first 2 medallions

These formulas do not take into account changes in gauge or stitch type within bands. For similar shapes to be achieved in machine knitting, the number of transfers would be prohibitive. In order to achieve similar shapes, one begins with the radius of the finished circle and the shapes in the family may be knit sideways, using holding.

Hand knitters can work with 4 double-pointed needles, one or 2 (or more) circular needles, and crocheters can follow similar shaping methods. The advantage to long circulars is less bunching up as the work grows, and if you like working flat or want to try the garment on while shaping it, you can use more than one long needle, making the piece or the try on manageable. Working from the top down when knitting such shapes may give one more control over the size of the finished piece i.e. on length of body and sleeves, height between bands, extending a yoke into a shoulderette or cape. Stitch pattern size and repeats add to the math calculations. Garter stitch is the only hand knit stitch that approaches a square gauge, could be used in combination with patterned bands.

The charted patterns above rely on M1 to increases. Yarn overs may be used for decorative holes at increase points. If preferred, the hole may be diminished by twisting the stitch when picking it up on the next round.

When knitting in stripes, the “jog” at the color change in knitting can be eliminated by slipping the old color purl-wise and starting to knit the second stitch. TECHknitting provides more alternatives in her posts: http://techknitting.blogspot.com/2007/01/jogless-stripes.html
http://techknitting.blogspot.com/2011/03/jogless-stripes-pretty-picture-version.html. For a method using yarn ends and a needle when the yarn is cut http://imgur.com/a/NREsH.

For shawl shapes and their geometry using YO increases, see the posts and publications by Holly Chayes.

To start it all from the center out: I am used to doing the magic loop cast on with a crochet hook, and then moving on from there, Kitty Falol shows it worked with DPNs.

Return to circles, knit “pies” 2, round yokes and more

Just as other knitwear styles have varied in style, ease, and fit over the years, round yoke sweaters have also done so. Yokes can be wide or narrow, in patterned or textured stitches, and in varied proximity to the neckline. This is not generally a tailored style. Ease in knits can be calculated on the basis of fashion or personal preference. With some familiarity with slopers, measurements may, however, be adjusted in this style as in any other sweater. Neckline measurements do not reflect the measurements achieved after adding finishes i.e. turtle or round. Depending on the size of the yoke, shaping can begin at the armhole level bind off (seen in the early hand knitting directions in the 70s), while smaller yoke shaping can begin at whatever point is desired, extending to the neckline, or simply to create a design band. The shaping is created by decreases if the garment is knit from the bottom up, and with increases, if worked from the top down. In most styles, the same number of rows are worked from the armhole bind off or held section to where yoke sections meet. At that point, if hand knitting on circulars the 4 sections: i.e. left sleeve, front yoke, right sleeve, and back yoke may be picked up and joined for completing the yoke. My illustrations have been created using Mac’s Pages lines and shapes.  They are not to scale.

Beginning to visualize the process: yokes are generally superimposed on raglan shaping

they form part of a flat circle; here is how they might appear in a partially seamed cardigan without front bands. They may be created in varying widths or patterns,

and in a pullover with shaping in the back that raises the rear neckline. Some of the early patterns were executed with front/ back and both sleeves sharing equal measurements and slopes

separate the elements: the yoke 

the front and back can begin to consider shaping at breasts, waist, and those wedges under where the yoke “circle” meets the sweater may be short rowed on each side with the intent of achieving a much better personal fit

sleeve 

Hand knitters are probably familiar with Elizabeth Zimmermann and her daughter, Meg Swansen. Handknitting with Meg Swansen 1995, and Elizabeth Zimmermann’s Knitting workshop 1981, Knitting around 1989, Knitting without tears 1971 are classical references that include information on yoke creation, including these guidelines

Other authors suggest 1/4 of total body and sleeve measurement in stitches (excluding armhole) for a tighter neckline (turtle neck), one third for a more open style (crewneck). Original circumference/ body measurement should include any ease. Though decreases for the yoke: first halfway up 25%(one out of every 4), second 3/4 of the way up 33% (one out of every 3), and last 1/2 inch before full depth is reached 40% (two out of every 5) are the most common, they can be placed and varied to suit your own design.

In drafting your own patterns and partnering with someone, a tape measure or string can be laid on the shoulder line, etc. for an idea as to preferred placement and measurement. Necklines finished by bound-off stitches whether machine or hand-knit, do not stretch, so measuring your head with something that does not as well gives you a guideline. Yokes end in open stitches, so the thing to consider there is what method is used to finish the neckline and its own stretch factor after bind off. Hand knitters have the added benefit of splitting the work onto 2 circulars and trying on the sweater or its pieces on while in progress to double check fit.

Japanese designers began to publish patterns that often included yokes that were constructed on the top of the drop shoulder line, with the back yoke placed higher than on the front. Such yokes also began to be represented in stepped figures showing decreases. In the round calculations are gauge based, not relying on the pi formula.

Yoke shaping may be indicated in a stacked format. The final count and frequency of decreases are shown, publishers may vary in language. On the first row here 4 sts – 2X means there is a group of 4 stitches followed by a decrease 2 times, then 5 stitches followed by a decrease 23 times, etc.

Two online calculators are available to help with DIY:  1. the Yoke-U-Lator no longer live, and 2. for Lopi, Icelandic styles. The image below is a screenshot from the latter website, indicating a sample possible result. There had been issues with Silverlight not working in some late OS updates, making the site unusable for many. On 3/12/18 after installing the latest update for the plugin from Microsoft, I was able to run it using both Safari and Firefox respectively.

Jessica Tromp offers free circular knitting patterns with a round yoke, dimensions in inches and ounces.

There are endless possibilities for combining math formulas, gauge, and pi. There are many ways to do decreases. With planning so that much more frequent intervals happen between decrease rounds, the decreases themselves can be fabricated to line up in line, and the resulting texture creates the interest in the sweater as opposed to any color patterning (i.e. along white lines)

“pie wedges” may be placed on neckline, yokes, sweater parts, various silhouettes and garment pieces, or full shapes (red dots outline possible dolman sleeve)from a Japanese magazine a hint of detail that must be calculated and the pie may be oriented in different locations on any one piece

“Decreases” in rib sometimes can be achieved through changes in needle size if hand knitting or tension changes on the machine. The yoke in machine knitting would need to be split into 2 parts or knit sideways. Plain colored rows between bands of FI may appear noticeably lighter in weight, so using a 1X1 one color FI pattern or double strand of one of the pattern colors may improve the look.

Before transferring stitches on the machine in the single color rows, make your transfers. The lace carriage may be used after selecting appropriate needles and putting them in position. Knit the following row before removing knitting on from the waste yarn or garter bar. If stitches are tight for garter bar use sometimes the row after transfers may be knit at a looser tension to facilitate the process, and the difference may not be noticeable when knitting at “normal tension” is resumed. The carriage should be set to plain knit for row prior to and after transfers. It may be easier to work toward the center from each side when returning stitches to the needle bed. In order to match the pattern at the shoulder seams or when motifs need to stack in position on separate bands, the stitches need to be rehung at specific positions on the needle bed that take into consideration the size of the repeat and its location within the stitch count. Also, take into account the seam allowance. One stitch extra on each of the meeting seam sides will allow the end needle selection stitch or an extra patterning needle to be hidden within a full stitch join. Working on machines that preselect needles or pushers makes tracking a bit easier. It is possible to combine knitting pieces in both directions. For example, knit yoke up toward neck, join shoulders and then pick up appropriate stitches to knit body and sleeves from the top down. Top-down makes any adjustments in length easier prior to finishing the sweater. Short rowing in garment segments underneath the yokes makes for a better fit at the bust line and upper back.

Going low tech: if gauge works out to whole numbers, shapes can be plotted out on square grid graph paper (or grid created within the software to suit) where each square represents one stitch, one row. Draw connecting lines, follow the outline, filling in squares (or removing them) as the edge moves a whole unit (k2 tog). Here the goal is to go from 39 stitches to 5 over 60 rows. Color bands could be added and planned between decreases, which should occur on single color rows. Once a gauge is obtained, charting on graph paper or within programs can be boiled down to connecting dots and following outlines as above. Some simple breakdowns for outlines of garment pieces/ shapes

Illusion DIY patterns in crochet

I previously posted on illusion knitting, and on one approach to designing simple patterns using the technique. The first 3 images below are of the swatch illustrating one of my hand knit patterns. 

Since I am now involved in a group interested chiefly in crochet, I got curious about executing the fabric in crochet. Part of the problem is that enough texture needs to be created to be able to read the “shadows”. I tried crocheting in different parts of the chain, around the posts in the row below, and ultimately went back to afghan stitch. I had not used the latter since making blankets first for my son, and then for my grandchildren.

Those of you new to the technique can find some instruction at the Red Heart website, and in a beginning how-to video from Crochetcrowd. I used Tunisian simple and Reverse Tunisian simple stitches to create my pattern. In this technique, chart texture rows are read right to left. The return rows are not illustrated. It takes 2 passes of color one, followed by 2 passes of color 2 to complete one pattern row. Yarn is carried up the side, color is changed in the same manner as in any crochet stitch. In my test swatch, no border stitches were planned for or included. It is always wise to test the repeat in repeat before working the fabric.

 two passes are needed with each color, so here is the repeat with double length columns     

A: color used   B: forward and backward pass for each color   C: number of passes to complete a single repeat. The highlighted box at the bottom indicates a completed single design row. Only 2 colors are in use in the swatch. I found it easier to track my work and the edges where the textures need to meet by using an additional pair of colors in the chart itself. Rather than use the crochet terminology I marked my first stitches with F and B for each color, referencing the front/ forward, and rear/ back vertical loops/ posts respectively. As one moves across the row from right to left, when the color/ texture change is reached, the yarn is brought to the front or the back as needed, and the next color/ texture is worked in the reverse post/ loop.

Both swatches were made using similar weight yarns. The crochet version required more passes back and forth than in knitting, where the work may be turned over and the texture reversed on each knit row. The knit repeat measured approximately 5.5 inches L by approximately 4W, isolating my best guess stitch number equivalent to the crochet one. The crochet swatch measures 7 inches L by 6W.
