Revisiting lace repeats, symbols, and charting

Lace knitting for many introduces knitting with 2 carriages for the first time. The lace carriage advances the cards, mylars, or programmed pixels in a design row with each pass. In other stitch types the knit carriage, once it is set to select needles ie using the change knob on KC, in punchcard machines,

or KCI for end needle selection, KCII for no end needle selection in electronic models, also advances the pattern a row with each pass. The advances happen in Brother machines when any carriage locks onto the belt and moves past the center 0 marking as it travels from one side of the stitches in work and past them to the other.
Electronic and punchcard published lace patterns may be used in both machines as long as when punchcard models are in use, the pattern repeat is a maximum of 24 stitches wide or a factor of 24, such as 2, 4, 6, 8, or 12 stitches in width for each complete repeat segment. This exchange is possible because the knit carriage does not advance the pattern repeat in both models, it is left set for performing plain knitting, with the change knob set to N-L.
When the knit carriage(s) is (are) also set to produce patterning, extra caution needs to be taken with the alternate carriage being off the needle bed so both carriages do not lock onto the belt, which will then be anchored on one side, and pulled toward that spot from the opposite side, possibly causing it to break. One instance in transfer lace knitting when the knit carriage also selects needles is in knitting automated edgings.
Many other stitch types may be knit with 2 knit carriages selecting needles from opposite sides. It is one way to have frequent color changes without using a color changer, tensions and cam button settings can also be different. On an electronic machine, each pass of each carriage advances the design by one row. Here patterns stop being interchangeable. With 2 carriages selecting needles, when a punchcard machine is used, as the alternate carriage makes its first pass from the opposite side, the card does not advance, so the previous preselection is repeated. To use a published repeat for either machine on the other, the repeat needs to be adjusted.
If one of the two knit carriages is left set to N-L, it will not advance the pattern, providing an easy way to add plain knit rows between patterned ones without having to alter cam button settings or the programmed repeat. In transfer lace knitting, there are many considerations when attempting to represent carriage movements for both carriages in a single chart when the knit carriage is not also selecting in pattern, but simply knitting and not advancing the repeat. The first illustrations use the machine knit repeat developed from a hand-knit pattern inspiration many a year ago 2013/12/05/lace-mesh-motif-charting_-mac-numbers.
Since then software versions, computers, operating systems, and my use of them have evolved and changed. I have edited the post with additional information, inked in a different color.
Experimenting with DAK has brought me back to thinking about the issues in charting lace fabrics in particular.

Two of the posts on using Studio repeats on Brother brands:

A Studio lace card with single blank rows between transfer segments knit on a 910
No symbols are used in this chart, generated using the DAK template print preview for knitting with a Brother model 950 i. The red cells represent transfers to the left with LC operating from the left, the green cells represent transfers to the right, and the grey cells indicate knit stitch rows.
The knit rows in most lace unless the pattern is combining KC needle selection for slip, tuck, FI, or weaving do not advance the pattern rows.
LC actions are marked on the left, the KC ones on the right
The LC makes 4 passes:
1: preselects for transfers to the left as it moves to the right
2: transfers to the left as it returns to the left,
3: transfers to the right as it moves to the right, there is no preselection for the next row
4: moves back to the left with no transfers or preselection
The KC follows with 2 knit rows. In the chart for this pattern, representing only the repeat, there is no room to indicate KC passes on the left-hand column
The appearance of the chart or template changes if 2 empty rows are added to represent the KC passes. It may help one understand what is happening but in Brother machines, 2 of the 4 blank rows here would need to be eliminated for the pattern to knit properly.
Making distinctions in the programming for the repeat depends on its use. If one is using DAK for interactive knitting, by necessity those extra rows are needed to allow for the view onscreen of the rows involved in the plain knitting with the knit carriage. I would assume knitters are instructed to set the knit carriage to KCI or KCII, each carriage will advance the knitting for a row with each pass, extension rails are a necessity since each carriage needs to engage the belt for patterning. Using the same repeat for drawing on a mylar sheet or for download outside the DAK environment the greyed-out 2 extra rows can be eliminated by marking squares or entering pixels and punching holes (depending on repeat width), and the remaining repeat should work.
If the image is being downloaded as is to an electronic, it may be used as given, with the knit carriage selecting needles and the cam button set to KC I or II.
Because printing template previews are produced using the fair isle option, the design will be mirrored, a necessity in some electronic models, but for punchcard knitting the same repeat with the extra rows removed, if accurate overall should be usable as-is. The numbering for the punchcard machine sequences however reflects the subtraction of the extra rows in the electronic template, the provided numbers then have skips in the sequences and do not match the actual design row numbers useful when a card is being punched.
Electronic carriages are equipped with a magnet, and must always travel past the center needle 0 position center mark on the needle tape. Markings on brand-specific published punchcards give clues as to which carriage to use and for how many passes. They also may vary depending on the year the punchcards or mylars were issued. To review, here are some of the markings commonly found
Lace knitting on punchcard machines a symbol summary:   There are many differences in transfer lace design: design transfer segments may vary considerably in the number of lace passes and transfers between each pair, or more in some instances, of knit rows. In the pattern below, only 2 rows of knitting are completed after 20 lace carriage passes, the bottom half is repeated X times, and the top half X times, adding even more complexity. Depending on the knitting machine model, the pattern may also need to be mirrored to knit accurately. Published punchcard books offer patterns with potential errors usually sorted out. Both punchcard machines and electronics scan the card or mylar inside the machines, several rows down below what is visible to the knitter at eye level on the exterior of the card or mylar slots, so markings on both need to be made accordingly. This is a fact that needs to be considered with cable downloads of the same patterns if entering memos for knit rows. In the case of punchcards, Brother reads 7 rows down, Studio 5. In fabrics other than transfer lace adjusting for the brand is straightforward ie to knit fair isle, tuck, or slip pattern if using a Studio company-supplied punchcard repeat, simply start the Studio card on row 3. If punching your own, design rows match, and if the blank card is marked for Brother, the numbering is accurate by default. Brother transfer lace cards begin with pattern selection, Studio brand with 2 knit rows. In this repeat, a mesh repeat is created first moving to the left, then to the right, the 2 knit rows follow 2 LC passes for transfers to the left, and 4 LC passes for transfers to the right. Brother row one marking is underlined with a blue line, Studio with red A Studio repeat adjusted for use on Brother also illustrates that the number of knit rows is only two, the LC passes can vary in number between knit rows. Here LC passes are marked with outlines around pertinent row numbers on the right   Brother vs Studio: extra knit rows in Brother are not physically left as blank rows in cards, the rows for KC are still 2 blank ones, while in Studio cards there is a blank row for each knit row in the pattern. Both these samples have a 6-knit row sequence. Because Studio begins with 2 blank rows, in the repeat on the right only 4 rows are left blank at the top of the repeat. Adjusting for extra knit rows, Studio to Brother These samples are from Brother punchcard volume 4:
single blank rows between transfer segments varying numbers of blank rows between repeat segments multiple rows of knitting (8) marked aside a single pair of blank rows Some electronic examples using the 2-row spacing between transfer segments: this is a page directly from the Stitchworld electronic pattern book a pattern published on a full Brother mylar sheet this is from a studio mylar, the same holds true in terms of the number of empty rows between transfers, that is the reason why most transfer lace patterns unless they are designed as studio simple lace where transfers are made with each carriage pass, patterns may be exchanged between both brands, the only difference being studio starts with 2 blank rows, ends with transfer markings, Brother starts with transfer markings, ends with 2 blank rows.
Electronic repeats are interchangeable after taking that into account, but not mylar sheets between machines, the respective brand mylar readers differ in the number of rows below eye level where the electronic readers scan the design, and the set or starting line will be in a different spot. 

Transfer lace may also be combined with other stitch types, each with its own considerations as in these instances both types of machines have the KC selecting needles as well. The punchcard published patterns need to be adjusted for use on electronic models. As already mentioned, punchcards do not advance with the first pass of the alternate carriage from the opposite side, while electronic models advance a row with each pass of both carriages:
adding KC slip stitch selection for creating ruffles and doilies
tuck stitch
weaving 1, weaving 2
fair isle

The lace module in Dak in theory will do the work for the knitter once the pattern is entered as symbols. Eyelets will be represented in single rows, a shorthand version of the previous samples. Reviewing how the transfers would appear on the knit and the purl side respectively. The LC can move only one needle at a time, so when multiple needles need to move to place the eyelets properly, the options are to use a hand tool to perform the moves or to develop a pattern with multiple transfers in each segment of the final repeat. The full repeats are often very long.

To mesh or not to mesh 8: more Numbers meet Gimp

A recent FB post led the discussion to this repeat from a 910 mylar, which does not have the immediately recognizable format of the Brother lace patterns if viewed in a small screengrab such as this. The repeat is included in Ayab test patterns. The full mylar collection and user manual may be found here http://machineknittingetc.com/brother-kh910-pattern-guide.html.
The segment including the lace pattern Brother was the first to allow programming from multiple areas on a single mylar sheet. Starting and ending stitches and rows needed to be entered, I got used to drawing boxes for each pattern as seen on the upper right, reducing errors in future knitting. The red lines on the copy highlight the repeat’s border. Mylars were read 13 rows down, punchcard machines7. The equivalent of arrow markings on lace punchcards are provided in the column on the left, which extends over the top of the drawing space by the same number of rows, allowing it to remain visible above the card reader even as the top of the mylar patterning area is reached.
The design is actually created from isolated areas of a mesh repeat discussed in a previous post. The lace carriage is used for 2 passes and then for 4 alternately, as indicated on the left side of the punchcard. The 2 passes will result in transfers to the left, the 4 make in transfers to the right. This repeat, usable in nonelectronic models, appears in my pre-punched factory basic packs as both #17 and #20. Depending on the electronic model or the software used to download patterns designed for lace, the final image may need to be flipped horizontally. This is true for use on my 930. Creating a template for mesh using numbers: begin with a table with square cells in numbers larger than you might need, ie 24 by 54. The method for doing so has been explained in previous posts. I happen to prefer cell units that measure 20 points by 20. The smallest repeat unit for use on any machine is isolated, shown bordered in red, is 4 stitches wide by 6 rows high, and drawn onto the template. The group of cells in the repeat are selected. If one hovers over any side or top and bottom borders of it, a yellow dot appears. Clicking and dragging on the yellow dot will repeat the full selection to the right, left, up, or down. Here the move is to the right The whole group is selected, and dragging on the yellow dot once more, the whole template can be filled Beginning at the top or bottom of the table, hide all blank rows. Using the command key during the selection process will allow this to be done on the whole table at once or in groups of rows at one time; 36 of the 54 rows are hidden.   At this point, there are a couple of choices. One is superimposing a solid shape. Using a contrasting color makes it easier to sort out its placement the color may be replaced with white in the spreadsheet,
unhide all rows, and the lace pattern is ready for the final steps before using Gimp The other option is to unhide rows on the colored table, screengrab as usual after removing cell borders. Open in Gimp, crop to content, eliminate the cyan row by filling it with white. It was intended as a placeholder for the last row in the pattern, is not part of the final repeat.
In this instance, I used mode, indexed, to the maximum of 3 colors.
Choose the color to alpha option from the colors menu.
Using the dropper tool select the color you wish to be made clear, and click OK. Create a new image of the same size.
Copy and paste the color-reduced image onto the new one.  Dotted lines will appear in areas that had the color removed previously. Clicking anywhere in the window outside the image anchors the paste and makes those dotted lines disappear. If that does not work, select the rectangle tool before doing so. The file is then ready for final scaling. The last image is in RGB mode once more, converted to BW indexed, scaled to 24 by 54, and exported as BMP or choose any other format ie png, etc. to suit your needs.
Responses to alpha selection can vary depending on the original color palette used when filling cells.
Creating a template for drawing simple shapes using transfer lace, it is easier to start with the transfer grid in a color, rows are hidden as above, and eyelet shapes are drawn in black. The rows are unhidden.    In this instance, the red was selected for converting to alpha with the image still in RGB mode, copied and pasted. The pasted image may be anchored in several ways. Using the image menu: select merge visible layers, or flatten image; layer menu: select anchor layer, or simply click on rectangle select tool and click again anywhere in the window. Changing the mode to black and white indexed will yield the repeat for final scaling. Each transfer design segment of the repeat is 6 rows in height and completed with 10 combined carriage passes. The lace carriage, LC, operates first, in a series of two passes at first, then followed by four, repeating the double sequence throughout. The mylar, card, or computer image, does not reflect the passes made by the knit carriage KC. The latter is set to knit, does not engage the belt, and does not advance the pattern. It helps to look at an expanded repeat to understand that indeed, transfers are made in 2 directions.
Referring to design row numbers, not necessarily those on a row counter:
1.  LC preselects for transfers to the left as it travels to the right
2.  LC makes transfers as it moves to the left, no preselection occurs, remains on the left side
3.  KC, moves to the left, completing the first knit row, creating loops on needles emptied by transfers, the pattern does not advance and remains on the same row
4.  KC, moves to the right, completing the eyelet stitches, the pattern remains on the same row, KC then stays on the right
5.  LC moves to the right, no preselection
6.  LC moves to the left and preselects for transfers to the right
7.  LC moves to the right, transfers to the right, no preselection
8.  LC returns to the left, no transfers or preselection, stays there
9.  KC moves to the left, and the pattern remains on the same row
10. KC moves to the right, and the pattern remains on the same row, KC then stays on the right Those familiar with eyelet formation in the more traditional transfer lace will notice the differences here, where the geometric shapes are technically superimposed on a mesh whose structure is revealed depending on where the transfers creating them take place. The fabric is easy and very quick to execute since most of it is in stocking stitch. The proof of concept swatch: The design was not planned as continuous, but is easily amended to be so. Here an alternate version is shown, with 2 linear repeats on the left, and a single expanded repeat to its right As for that mylar repeat, this is an image of the shapes with the chart collapsed, eliminating blank rows between black pixels. The resulting partial test used as drawn In fabrics designed this way, using the image as drawn (left), or mirroring it horizontally, does not visually change the result. This does not hold true in more complex transfer lace.
Several large-scale designs based on this method are found in Brother-electro-knit-lace-patterns-3 This random chart from the publication shows a pattern where the number of transfer rows between knit ones has more variation. Again, knit rows are marked in the column on the far left. Those marks on a mylar would remain visible on the outside of the machine, above the card reader as one progresses through knitting. Memo windows or handwritten charts may be the only option for accurate tracking, depending on the machine model and the row count variations. The repeat may also require it to be flipped horizontally. Simply reaching a row with no needle selection does not always mean the location for the 2 knit rows has also been reached. 2024:
The above is listed as a fine lace pattern. Most such patterns can be executed as  standard transfer lace as well.
The addition of the ArahPaint guess weave from grid tool makes the process of converting charts such as the above easier and quicker.
The final BW chart and the associated 60X74 png. Depending on the machine model, the file may need to be mirrored horizontally before any knitting.  in repeat The original image had markings for mylar that inform the frequency of knit carriage passes, which extend above the start and end of mylar markings to allow for the fact that the first design row is scanned below the row visible to the knitter on the exterior of the machine. When the png repeat is loaded into machine memory, reading begins on row 1. The knit row single pixel markings on the original can still serve as guides as to how many passes of the LC are followed by 2 knit carriage passes The column on the left indicates the number of LC passes before two knit carriage ones, the column on the right reflects the corresponding design rows. The image from the publication, with the color modified for clarity My sample was knit on a 930, hence mirrored horizontally, on 60 just stitches.
The yarn is a softly spun rayon with a tendency to split, and at the end of the second full repeat several stitches dropped, accounting for the length of the swatch;-)  The second volume is also available as a free download, and in addition, mylars are as well.
The latter makes for clearer stitch and row counts and easier file conversions.

Large scale mesh, a punchcard repeat adapted for electronic

Previous posts including fabrics in this family:
2011: Large-scale mesh, breaking the rules 
2013: Large eyelet lace, hand transferred (or not)
2020: Revisiting large eyelet lace, hand transferred (or not)

This was the punchcard provided in the first post, knit with 4 passes of each carriage, the knit carriage set to tuck in both directions Brother punchcard machines do not advance pattern rows when two carriages are used for needle selection as each carriage begins to move from the opposite side, the same preselection is repeated. This means editing is required at times if the same designs are to be used on electronic machines, particularly true in lace combination fabrics. The process has been discussed in posts on automating lace edgings with slip stitch settings.
End needle selection is canceled in both carriages, if any end needles are selected prior to a lace carriage pass, they need to be pushed back to B position manually in order to avoid transfers resulting in decreasing stitch counts or dropped stitches.
All versions proposed below share transfers that result in 3 stitches on a single needle, with two empty needles on each side of them.  Here the needles are preselected for the next pass which will begin to fill in the double space, the needle in D position will knit, the one in B position will tuck;   this is how the yarn is laid over those 2 needles after the first tuck row is completed,  and both when using the card and in the first electronic repeat there will be a third tuck loop that is laid over the needle holding the 3 stitches. This is the appearance of the stitch formations just prior to an all-knit row  Here analyzing the actions of the punchcard, marking rows according to card actions, the repeat is expanded to include the extra duplicate rows. Though the repeat remains 24 stitches wide, it is no longer usable for use on a punchcard machine. For knitting on the 930, the design requires flipping horizontally in order to knit properly. The third tuck row may be eliminated to produce an extra all-knit row, resulting in a slight difference in the shape of the eyelets Lastly, the repeat may be amended with extra stitches and rows between each eyelet  


Lace meets FI on Brother machines

Very little has been written on this topic.
The easiest method to produce the eyelet and fair isle combination is to create ladders in spaces between vertical FI motifs. The end needle selection is canceled. The swatches show the transitions in the development of the final design

Susanna in her Machine Knitter’s Guide offers a version knit in combination with the ribber on page 218, and a small amount of information on single bed versions on pp, 220-221.
Before any DIY, I like to start with a published pattern. Toyota, in this volume,    offers 4 punchcards for use with this technique I chose to work with #170. The lace carriage in the Toyota models operates from the right side rather than the left as in Brother. The direction of the arrows marked on the card actually indicates movements for the carriage operating from that side. That fact is taken into consideration planning a possible Brother punchcard repeat. Lace direction arrows are matched based on the punchcard image being mirrored horizontally. The card in its original version is imaged on the left, mirrored on the far right, the proposed Brother punchcard in the center The proposed Brother punchcard repeat is now expanded for use on the electronic machine, ready for converting to .bmp in Gimp. Numbers in the middle of the chart on the left helped keep track of repeat segments. I also used red dots initially to mark segments as I had completed in the expanded the repeat, then erased them
  The Gimp magnified punchcard repeat  in turn in need of mirroring for the .bmp to be used in the 930the resulting fabric Observations and settings:
The knit carriage is set to FI patterning for the knit rows, the typical floats will be created. Commonly, when floats are wider than 5 pixels, anchoring the longer ones may become a preference or even a necessity. This would add time to an already complex fabric. Each FI design row is repeated twice.
The transfers in this design are made on the yarn in the color in the B feeder. I began my swatch using the light color yarn, failed to switch its position to the B with color 2 for the shape in A, accounting for the dark stripe at the swatch bottom
If KCI is used, end needle selection will be made prior to the lace carriage passes. Those preselected needles will have to be pushed back to B position by hand prior to using the LC or they will transfer on one side and drop on the other.
In this pattern, the LC operates for 8 passes, followed by 2 rows of FI throughout the piece. The first preselection row is made with the KC from the left as it moves toward its home on the right.

What of DIY? From working on the repeats for transfer lace combined with weaving, I understand patterns beginning with transfers to the right rather than the familiar to the left, are shortened considerably and carriage changes may be made as often as every 2 rows, saving many carriage passes. In order to understand the choices that need to be made, I began with a lace transfer pattern, thinking I could add contrasting color shapes in FI. I expected something like this however, the swatch had issues. The eyelets were not occurring in the same spot in both directions, the color transition at the repeat intersections was clumsy Regrouping: the easiest place to insert eyelets is in the dominant, background-color The 930 .pngA quick test: rows with no needle pre-selection will knit in only one color, end needle selection must be canceled before knitting to the other side Can the exchange of the color positions in the yarn feeder create colored shapes with eyelets on the white ground? not only does it not do so in a way I liked, but my machine was having none of it as well  Coming up with a better plan resulted in the following repeat. The transfers are made in the wanted direction on the purl side of the fabric, so their location becomes easy to check and identify during knitting. In this exercise, they will be placed in the center or the previously knit fair isle rows. Magenta cells marking the doubled stitch after transfers to the right, the cyan one the doubled stitch after transfers to the left. The two blank rows at the top of the design will knit in the background only. Building the repeat in Numbers: the eyelets within the shapes in the contrast color need to begin and end with a pair of FI rows. They are placed taking into consideration the black cell blocks immediately below them, not the ones directly above It’s good to start with a small repeat.
A: one may begin with a planned repeat, in this case, 20 rows in height
B: create a table at least twice the planned height or start with a long template that in turn will have half its rows hidden. Holding the command key select every other pair of rows beginning with 2 blank ones at the top of the table, and hide them. The location for the options to hide and unhide rows and columns:  C: Once the rows are hidden, the black cells are filled in
D: the repeat is tiled to check its alignment
E: the hidden rows are unhidden,  I like to add colored cells as shown to ensure proper placement of eyelets
F: place black cells for stitches to be transferred where desired
Previous posts describe the steps to isolate the repeat as a screengrab and importing it into GIMP. The grab is cropped to content, image mode to indexed, scale to the proper size, mirror for use on the electronic if needed, save, and use the final image to download to the knitting machine for testing.
The first pair of rows are knit in FI, so the preselection for design row 1 is from left to right.  The KCI setting will bring end needles out to D prior to lace rows, those needles need to be pushed back to B position prior to moving the LC from left to right. Continue with switching carriages every 2 rows. This repeat is 20 rows high. When knitting the last 2 rows, no needles will have been preselected, except for first and last. Push them back to B for those two rows, so only the color in the A feeder knits, and the preselected needles do not drop off the bed. The second color does not need to be removed from its location, but in executing a wide piece of knitting, the extra yarn pulled down from the tension mast as the knit carriage makes its passes may cause issues. If the yarn is removed and held aside, be sure to place it back after the 2 passes with the ground color so as to avoid forgetting to do so prior to resuming patterning using 2 colors per row. Taking it to continuous shapes and checking them in repeat: red cells represent transfers to the right, cyan ones the transfers to the left. The empty cells adjoining each of both colors represent the location of the doubled-up stitch after the transfer is made I like to check tiling for the repats along the whole process
Though the repeat is 24 stitches wide, it is not suitable for use on the punchcard machines in this format, its tiled test and .pngThe one area where the white got picked up with the contrast is not due to programming, but likely to operator error in “correcting” a dropped stitch Adding another contrast color stitch to shapes will make the number of stitches on either side of the eyelets consistent  Adding lace shapes in the ground can follow the same concept The repeat does was not planned as a continuing pattern, but here it is knit and repeated in height X 2 and with the addition of two blank rows at the top of each segment.
The possibilities are endless, with some patience, they can be manipulated to meet personal preferences and taste.

Lace meets tuck on Brother Machines

Some DIY variations in combining both stitch types:
Combining tuck stitches with lace 2 (automating them) 3/15
Combining tuck stitches with lace 1 3/15
Large diagonal eyelet lace, (a similar card and fabric, not tuck setting) 6/12
Large scale mesh, breaking rules 4/11 explains the use of punch card below
Tuck stitch combination fabrics 5/19
To execute this knit fabric, the lace carriage is set for normal lace, the knit carriage selects a pattern (KCI) and both tuck buttons are depressed. Each carriage works in sequences of 4 passes/rows throughout. The self-drawn card does not include familiar arrows on the left-hand side familiar to users of factory published lace cards Working out an electronic repeat: the punchcard repeat is on the bottom, the expanded electronic one on top, yellow cells highlight rows with tuck stitches In electronic machines, the first preselection row may be done with the knit carriage moving from left to right or the lace carriage moving from right to left, with either carriage moving toward its usual starting position. The knit carriage is set to KCI for end needle selection. Before the LC begins to move from the left the first and last needle will have been preselected, push them back to the B position. Continue to do the same if any end needles are selected just prior to a transfer row as you continue to knit. Each carriage makes 4 passes throughout the piece. The bottom row of eyelets shows the “standard” size eyelets that follow single transfers, illustrating the change in size with this technique.  With the proper tension, transferring is not a problem. I sampled on a random number of stitches. For cleaner edges, a border where no transfers occur for 2-3 stitches can be planned in programming the final piece.
Returning to Volume 4, here is a combination of lace and tuck repeat that appealed to me. I am repeating a process akin to that used in programming the woven lace samples. In this card, lace transfers are first to the left, then to the right, that sequence needs to be preserved. Colored pixels need to be used everywhere a punched hole is represented. The lace portion of the card will not tolerate color reversal. The published full repeat is for a brick configuration, I sampled the top half.  The actions of the 2 carriages on the electronic, the repeat prior to mirroring mirrored for use on the 930  The texture is more apparent on the purl side, the top and bottom edges could be coaxed into a wavy shape due to the gathering up of the knit by the tuck diamond shapes The chart for the brick configuration: An advanced technique fabric, combining lace, transfer lace, and tuck patterning

Lace meets weaving on Brother Machines 2

Early Brother punchcard volumes showed symbol charts alongside punchcard repeats. The translations at times were not the best. Here is some of the advice offered for woven lace patterns:  

This was one of the first such punchcard volumes published by Brother after the pushbutton earlier models were replaced by ones with card readers It has the added data on how each of the fabrics might look visualized in a chart prior to its expansion as a card in full repeat. This is the top half repeat of a card for pull up weaving combined with lace along with the directions for execiting the knit My experience with trying to knit CARD # 589, led me to notice immediately that all carriage passes, if the arrows are followed, are made from the same side. That avoids the repeated selections when carriages first start operating from the opposite sides. My interpretation of what the card is achieving: Taking carriages on and off the same side of the machine is nothing I would be inclined to do for any length on any machine. In theory, the identical repeat above could be used on an electronic KM in that way, but I did not get very far with that method before giving up.
The expanded the repeat for use on my 930, with programmed all-black pixel rows for any pairs of all knit rows, made for smooth, easy knitting The weaving yarn used in patterns such as these will be held in the hooks of the needles, combined with the knit stitch already there. In this instance that adds up to 5 loops that need to knit off smoothly on the next knit row, so yarn thickness choice meets with limitations.
The first preselection row is made from left to right with the knit carriage, it resumes patterning on the right, beginning the weaving pattern. End needle selection is on, KC I.
When the knit carriage is on the right and all but those single needles are selected on design rows 5 and 23, pick up the floats from the weaving yarn with a single eye tool and lift them onto the non selected needles, then bring the same needle out to E position before moving the carriage to the left to create the first all knit row.
Before transfer rows using the lace carriage, if any end needles have been selected in pattern push them back to B before traveling with it to the opposite side. The electronic repeat, followed by its .png

Later punchcard volumes ie 4 and 5 took into account the repetition issues when carriages select needles for patterns from opposite sides, and that may be the best place for card designs that may be knit following arrows as shown, in the traditional manner. This design has fewer woven rows, a larger lace motif Volume 4 offers only this advice: “the empty needles are selected at the second lace pattern, but this is not a trouble, and you may pass the L carriage to the side which is indicated on the punchcard”. I take that to mean that after a transfer if the same needle is selected again, don’t be concerned, keep moving the carriage in the direction of the arrows. Because the weaving is for only 2 rows, the use of laid in, thicker yarn is well tolerated.

E-wrapping or other weaving techniques may be used on “weaving” row preselected needles, needles can also be hand-selected in knit areas in any other programmed lace repeat to add details on the chosen row(s) without engaging the card reader. Knit 2 plain rows, select weaving needles, wrap the yarn over or around them in the desired configuration, knit 2 plain rows again, and resume lace patterning. Varieties of wraps for use on every needle with yarn similar in weight to the ground, or every other needle with thicker yarn. Once the desired effect is achieved, a repeat could in turn be configured and punched or programmed to make the process easier to track.

A lace quest

This image sparked my search for a method to develop a DIY pattern for a similar lace It is taken from a video by Knitlabo, a wonderful resource for both Brother and Studio machine knitting. My first goal was to work with a recurring triangular motif in a brick repeat. The same repeat was also used in my previous post on using lace motifs in ENR (every needle rib) fabric.
The extra rows of knitting and the added contrasting color stripe between lace segments helps to visually separate them Before some light pressing, the lace had an interesting quality, harking back to my days seeking to form 3D scales A start at a brick repeat adds spaces for mesh eyelets to be added between the punchcard repeats,  the grey lines help align continuous vertical stitch placements The first effort to add the in-between eyelets is made easier if different colors are assigned to the left and right transfers, in this case, red for left, green for right Planning for the electronic repeats in a brick layout, still eyeing center lines, now every 12 columns. In addition, the bottom half of the chart is marked with the location of stitches doubled up after transfers visualizing and thus avoiding side by side transfers and other issues “on paper”. A single, full repeat is bordered in black A variation of the brick repeat, adding extra knit stitches aside previous mesh and knit shapes The related swatch segments:
A: the pattern with extra knit stitches, the error was an operator one, the result of mis-correcting a dropped stitch
B: the mesh without the extra knit spaces
C: B with extra knit rows. If adding a contrast color, knit 2 rows before changing color with the ground yarn, 2 rows or more with the second color, 2 rows of the ground once more prior to resuming transfers. The knit carriage in this fabric does not advance the pattern. The G carriage could be used to add purl rows between chosen repeat segments. The repeat is 24 stitches wide and because only the lace carriage is selecting needles and operating from the same side, it could be used, mirrored, on a punchcard machine.

Lace meets weaving on Brother Machines 1

Several years ago, this punchcard was shared on Ravelry as one that was problematic in execution on an electronic model using Ayabthe supposed related swatch pictured in the publication
At the time, I made a long, convoluted effort to produce the fabric. I am returning to the topic and comparing 2 cards in this post, the original 589, and a new-found cousin, 259. Looking to the published cards for clues, remember that markings for carriage movements related to the first design row at the bottom of the card begin on the left of the card, above the Brother line numbered 1 on the right. The start of both cards: Lace patterning is unique in punchcard use. The card does not begin with the reader locked. As the carriage moves to the right, the card will advance a row. The lace carriage will begin to move in the direction of the arrows, making transfers on preselected needles in the direction of those same arrows as it moves away from and returns to the opposite side.
A typical pattern for mixing weaving and lace, seen in 259, usually starts with a blank row, followed by 2 rows with lace transfer markings, and a single every other needle arrangement row intended for the weaving pattern, repeating in varied sequences for the height of the card. The source for the repeat is  Brother punchcard pattern book volume 5. Due to the added experience I have acquired in working with spreadsheets and converting lace punchcard repeats, it took literally minutes as opposed to hours to produce a working repeat for use on my now 930 and the desired proof of concept. It is interesting how our perspective and skill can evolve over time. This is the new, “quick” version,  beginning with flipping the card segment over horizontally, a requirement with Ayab or img2track on my 930. 259 shows the traditional approach combining the two techniques that take into account the fact that when the second selecting carriage starts to move from the opposite side, the punchcard does not advance, repeating the same preselection. Added discussion of the differences in repeats for both machine types may be found in the post: Doilies: Lace meets hold and goes round In this instance expanding the punchcard repeat with extra blank rows to allow for extra LC passes to maintain proper transfer direction is not necessary, but the repeated punchcard selections need to be taken into account. There are 2 options for starts: if beginning with lace rows, the first preselection row is from right to left with the LC, if beginning with weaving, the first preselection pass from left to right. End needle selection is in the KC is canceled. As knitting progresses, if an end needle is selected in the pattern push it back to B prior to making transfers in that row. The movements when working with two selecting carriages on the electronic are standard, the repeat advances a row in the design with each pass of the carriage. Here each carriage operates for 2 passes, to and from its original side after the first preselection row. I began my proof of concept with woven rows. The punchcard repeat has been reversed  The top swatch tests the repeat as given above, beginning with the weaving pattern. Mirroring the repeat also produced an interesting variation, as seen in the bottom test A review of 589, showed that it could be knit using each carriage for 2 passes as done above.  The same repeat as the one in the original punchcard, mirrored, produces the same fabric on the 930 as with using the more complicated separation methods described further below. The chart depicts the desired actions. My first row was knit with the KC set on KCII, preselecting while knitting a plain knit row from left to right, followed with the first lace transfer pass also from left to right the electronic repeat and its .png Analyzing the card, sorting out possible repeats follows since mylars or bitmaps for download often only require a single repeat of the pattern. If you are not used to doing this, sometimes beginning with recognizable vertical ones first is a bit easier. The first problem: matching the arrow markings beginning just above row 1 mark on the right, it appears the first set of transfers should be to the left, The pattern is simply not workable as given using both carriages selecting needles from opposite sides of a punchcard machine, each moving for 2 rows.
Reworking the repeat for use on the electronic in order to use the LC for four passes, beginning and returning to the left-hand side of the machine: the movements of the respective carriages on both models are plotted out, beginning with the theoretical punchcard one, mirrored horizontally, on the left, expanded in the center for the electronic, with the final repeat on the right. I now use different color cells to represent the direction of the transfers, here red for ones for those to the left, green for those to the right. The grey rows indicate blank ones that are required for the lace carriage to perform the necessary selections, transfers, and then to complete its return to the left side of the needle bed the smallest, single repeated in width X 2 for use on my 930its .png Extension rails must be used as both carriages engage the belt. The LC operates from the left-hand side for four passes throughout. The KC from the right for 2 passes each time. It advances the design by one row for each pass, preselecting needles or blank rows depending on the presence or absence of pixels as it would in any other fabric type. End needle selection is canceled. The weaving yarn is laid over the groups of every other needle in D position. A quick proof of concept swatch, the ground yarn may need tension adjustments for the best result an interesting variation with the above repeat flipped horizontally the mirrored repeat is used in the top swatch, any dropped stitches will result in floats. The repeat prior to mirroring was used to knit the bottom swatch. Dropped lace transfers may be missed behind the laid in thicker yarn. Transfers may need to be made manually if they continue to be a problem, especially if the ground yarn tension needs tightening in order to achieve the desired effect.  Starting the piece with 2 woven rows, rather than lace transfers: charting for working with the LC operating from the left for 4 passes, the KC from the right for 2 passes (worked on my 910, using mylar):
comparing the sequences for both starts, weaving on left, lace on the right Patterning issues are not always due to needle selection problems. Weaving and lace pattern combinations may be tested in lace first to establish eyelet selection accuracy. Here the weaving test failures were due to a problem with the sinker plate. The weaving lever was working properly in one direction only. Check that both brushes are turning freely. If they are not, remove the screw and any fluff caught under them before replacing them and continuing to knit. Occasionally the lever that moves the brushes up and down fails and a new part is called for. Here, the hand technique success followed a change of the sinker plate a sample using 2 different weight yarns; irregular weaving may require changing the yarn, or adjusting the tension used for the background yarn I like to test these repeats first in transfer lace, to sort out the best tension and yarn to use, errors in programming, Taking another look at the original punchcard and those arrows on the left-hand side, a detail I had originally missed, they all start from and return to the right, the line thickness changing marking the alternate carriage Both carriages operate from the right side, for 2 rows each, switching their place on the machine bed. Arrows for design row 1 begin above the red line. Transfers are all first to the left, then to the right. The card advances a single row for each carriage pass. With carriages operating from the same side, the punchcard advances one row for each carriage pass As I was trying to understand what was happening, I was also able to produce a swatch using the original #589 card, using a method that, however, produced all lace transfers to the right, and differed from the desired effect:
KC passes are indicated with green text, LC passes in blue
Pass 1: COL, KCII, N for a knit row which preselects the first weaving pattern row, knit to the right
Pass 2COR, KC, EON preselected, set the card to advance normally, lay in weaving yarn, KC moving  to the left will weave the first row, preselect the second weaving row
Pass 3: COL, KC weaves second-row EON, preselects the first row of lace on its way to the right
Pass 4: COL, LC transfers to right, repeats previous row’s selection, as it moves to the right 
Pass 5COR, LC no transfer happens on empty needle selected for the second time by the previous row, selects for the next row of transfers, moves to the left
Pass 6: COL, LC transfers pre-selected row to right, preselects first EON row for weaving, moves to the right, release it, return it to left
Pass 7COR, KC, EON, lay in weaving yarn, KC will move to the left and will weave the first row, preselect  second weaving row
Pass 8: COL, KC weaves the second row EON, preselects the first row of lace on its way to the right
Pass 9: COL, LC transfers to right, repeats previous row’s selection as it moves to the right
Pass 10COR, LC no transfer happens on empty needle selected for the second time by the previous row, selects for the next row of transfers, moves to the left
Pass 11: COL, LC transfers preselected row to right, preselects first EON row for weaving, moves to the right, release it, return it to left.  This row matches design row 1 and is starting the repeat sequence again
Passes 2-11: each group complete 10 rows of knitting the knit, produced at the time on both my punchcard machine and with my 910 also requiring an LC release on its third pass, reflect all the transfers occurring in a single direction

Unconventional uses for punchcards 3: lace in rib

Lace patterns for drop stitch: 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 (lace carriage will not be used), cancel end needle selection, program your repeat, push in both part buttons. As the carriage moves across the bed selected “lace” pattern needles will knit, the non-selected will be skipped.
Continue to knit until no needles are selected. At that point disconnect the main bed and ribber carriages, change the setting on the main bed to knit, remove the yarn from the feeder, bring the knit carriage alone across for 2 rows, and stitches will be dropped. After the disconnected carriage is returned to the opposite side, rethread, and connect again to the ribber carriages, set the knit carriage to slip and it once again will knit selected needles. Repeat the process for the length of the swatch. If on an electronic machine with 2 carriages: 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 will drop the stitches on “plain knit rows” on lace card without requiring the other additional steps and cam button changes.

Transfer lace on the top bed: the question periodically comes up with regards to the possibility of using the lace carriage when knitting every needle rib fabric. The lace carriage does not operate with the ribber bed in use in the standard up position, there is not enough clearance between the beds for it to travel from one side to the other across the needle bed. It is possible to drop the ribber down one click, opening up the space between the beds, supposedly to allow for the use of thicker yarns.

My machine is old enough for the ribber to be bowed in the center, increasing the space between the beds there. Trying to use that position for every needle rib in my desired yarn I got yarn breakage in the center of the bed, some skipped stitches, and the sides of the needle bed were still up too high for the LC to have a clear passage. The problem appeared to be due to its brushes hitting the gate pegs. With the brushes removed, but with some grinding against those same gate pegs the LC was able to move along the top bed. At least on my machine, I am giving up on the idea of using it, even if only to preselect needles, let alone make transfers.
This page is from the Ribber techniques book. The fact that transfers are broken up with blocks where there are no transfers, including some with stitches transferred to the opposite bed, makes it easier to track transfers than if using all over designs. Standard pronged tools are sufficient to move the single stitches or groups of three. 

It is possible to transfer larger groups of needles on the main bed to create lace patterns, done of necessity in two-color brioche, but here I am seeking to modify lace punchcards so that the fabric based on them may be created successfully with as few errors and dropped stitches as possible.
My first attempt was made using a second knit carriage set to slip in both directions to preselect needles for transfers,  using a small lace repeat to test the idea. The advantage of this method is that the original lace repeat does not need to be altered in any way. The disadvantage, aside from requiring a second carriage to use, is that the width of the piece on the machine is limited.  The ribber carriage is in use and needs to remain at least in part on the machine bed on the far right, limiting the number of needles for possible use on the right side of 0 to about 20. The same work could be done using only one knit carriage as well, but that would require changing the cam buttons from slip in both directions to knit and back to slip at the appropriate points, one of the methods that make it possible to knit lace on the 260 bulky machines

The repeat used is for this swatch is from StitchWorld, and is knit using the second knit carriage for needle preselection.  Because each block contains lace transfers in only one direction, the fabric, even though it is a rib, reflects that in the biasing first in one direction, then in the opposite.

It helps to be clear as to whether one is producing lace repeat for use in a punchcard or an electronic model which in turn will require mirroring, such as when using Ayab or when using slip stitch selection with the knit carriage in combination with lace carriage selections to create shaped lace edgings. Testing on a small swatch will help determine whether mirroring is required for any specific design. Electronic machines usually produce the design as seen on the knit side, punchcard machines as they would be seen on the purl, thus making mirroring a requirement depending on the source for the design.
I usually begin by modifying my chosen repeat in a spreadsheet. On the left, the pairs of blank rows in the original repeat are temporarily colored in grey. It helps to be consistent. One repeat begins with a full motif, the other with half, which can be confusing when first starting out. The plan is to begin by producing a trim or edging, an all-over pattern for significant lengths appears daunting. Dropped stitches in single bed lace are no fun, in rib they may not even be noticed until the knitting is off the machine. The difference between the two repeats: the 2 grey rows on the left are replaced by black pixels or punched holes, with a blank row placed above and below each of the black row pairs. The design is now expanded from a 40-row height to a 50-row one suitable for use in a punchcard machine This explains some of the desired knitting actions Using the method described in other posts, this was the screengrab imported into Gimp. The grey line is a reference point. Cropping the image to content will allow the last blank row to be preserved by having the grey one there. After the crop, it can be bucket filled with white, or when the image is, in turn, bitmapped to B/W, you may find it disappears. Image scale is then used to reduce the repeat for knitting. This is the repeat used to knit the swatch in my 930. If working from it, punchcard knitters need to mirror designs from an electronic source such as this and will find it easier to do so by turning the card over, marking the holes that require punching on that side, doing so, and then inserting the card in the reader in its usual orientation.  The 930 .png: Prior to knitting the pattern using the ribber, it pays to test the repeat single bed to get a sense of where the knit rows occur and to make certain the transfers are happening in the correct direction and in what place on the needle bed. There should be no side by side empty needles, and in this design, the first pairs of transfers result in 3 stitches on one needle in the center of each shape, not side by side holes as seen here in the false start prior to mirroring the image Making things work: both carriages will be operating to and from the left-hand side. The process is facilitated by the use of an extension rail and a color changer. The knit carriage alone will operate to preselect the needles that will need to be hand transferred to create the lace pattern. With the following modification of the repeat, all transfers are made moving away from the knit carriage. So if the KC is on the right, transfer to the left, if it is on the left, transfer to the right. The paired carriages will create the two all-knit rows between lace segments. The blank rows above and below the two all punched or black pixel rows are there to return the carriages to the proper, left side to begin preselection for the next row of transfers. If any end needles are preselected on the knit bed, push them back to B.
It is best to knit 2 rows of full needle rib before beginning transfer, that will ensure that stitches on both beds are formed properly. I did not, had a spot on the cast-on where the loops were not properly placed on the comb, and that is reflected in the area that looks like a stitch was dropped. Begin with a zig-zag row from left to right, knit 2 circular rows, carriages will be on the right. Knit a sealing row to the left, followed by 2 all knit rows, ending with carriages once more on the left side.
COL: remove the yarn from the Knit carriage, hold it in color changer by pushing the adjacent feeder number
separate the 2 carriages
cancel end needle selection
KC is set to slip in both directions, it will remain there for the duration of knitting the pattern, make certain all main bed needles are in the B position
KC operates alone to the right and preselects the first row of transfers
COR transfer preselected needles to the left, away from the carriage. Make certain all needles are in the B position before the next carriage pass. KC will preselect for transfers to the right as it returns to the left side.  Repeat the process until all needles are preselected for an all knit row as you knit back to the left
COL pick up the yarn, engage the ribber carriage knit 2 rows on all needles
Repeat: *COL: remove the yarn from the Knit carriage, separate the 2 carriages, operate KC alone making transfers away from the carriage until all needles are preselected as you knit to the left. 
COL pick up the yarn, engage the ribber carriage knit 2 rows on all needles** until ready to continue in every needle rib.

This method is slow, I found it oddly meditative. It offers an opportunity to review stitch formation, thus avoiding dropped stitches. Hand transferring lace preselection on the single bed as well can sometimes make a fabric achievable that is otherwise cursed by dropped stitches and fiber issues.

A return to Ayab knitting

9/18/21 There have recently been efforts to provide the Stitchworld I files for easy download for electronic knitting. The file is in progress, the work of Thomas Price, it may be found at https://github.com/t0mpr1c3/ayab-patterns/tree/master/kh930. Click on the main folder “ayab. patterns” and then click on the green button at the right top of the page (code)
My starting document for subdivisions into categories: ayab patterns.numbers
I have been asked about Lace categorizations in the document, and specifically about fine lace.
Folks without access to the github can find similar collections of electronic repeats on KnitStudium.com 
Fine lace is created by changing the setting on the lace carriage between N and L whether for a whole piece or between the 2 settings on combination fabrics. Instead of being transferred from one needle to another, when the F setting is used, the single stitch is shared between two needles. Depending on the yarn and tension, far smaller eyelets may still appear. In my opinion, fine lace fabrics have a texture that is so “fine” that unless one is using a light shade of yarn with a smooth twist that highlights the changes in the surface of the knit the resulting texture may be hard to recognize. The combination fabrics have both eyelets and surface textures.

There are illustrations from punchcard books and accompanying instructions on what symbols mean in my blogpost
https://alessandrina.com/2017/12/08/punch-cards-to-electronics-book-symbols-and-samples/
Fabrics using the word lace in their name may not necessarily use the lace carriage or result in the familiar LC transfer eyelets

Variations using L point cams: punchcard machines method for isolating and/or spacing lace motifs or columns, I have read some folks have used cams on electronic machines as well
Tuck and lace: LC transfers combined with tuck stitch patterning
Woven lace: LC transfer lace combined with the weaving technique
Lace and fair isle: LC and FI patterning, both carriages selecting needles
“Lace-like patterns”: possible in machines such as Brother and Passap, which allow for the same stitches tucking in one direction, slipping on the return of the knit carriage to its starting side. It matters which cam button function leads in the start of each pattern
Punch/ thread lace: thick and thin yarns used together in machines that have the option of a setting that allows for knitting both yarns together in unpunched areas or blank pixel rows, with traditionally, the thin yarn knitting in the front of the fabric, the thicker floating behind it
Tuck lace: tuck setting in both directions with specific needles out of work
Ladder Lace: worked with columns created by needles left out of work
Punch tuck rib: every needle rib combined with tuck setting patterning on the knit bed Drive/ drop stitch lace: stitches start on either of the 2 beds, and loops are picked up and dropped on the opposite bed
Shadow lace: stitches are moved between beds in a pattern to create knit stitches on purl ground or vice versa

Repeats can be used in multiple cam settings:
Fair Isle repeats with short floats may often be used in other stitch settings
Though listed in the FI section, 3 A, B, and C are knit as tuck stitches with needles out of work, NOOW
Any patterns with large floats ie 6 -8 are best knit as DBJ, double bed, ribber setting
In patterns such as #43, the left-hand column lists numbers 2, 3, and 4 indicating color changes in the B feeder, while maintaining a constant color ground in the A feeder
Any single motif pattern may be used for DBJ if programmed accordingly
Many FI may work well when programmed with the G carriage.
Transfer lace, fine lace, and combinations of both are used exclusively for that fabrics.
Tuck patterns are safe to try with every cam setting, though the resulting knit may not be exciting. Most containing single or double rows of white squares may be knit double-long for more texture. If the tucks occur for 2 or 4 rows, with a color changer it becomes easy to change colors every 2 or 4 rows respectively, and patterns with many white cells may result in a knit that looks like what is often referred to as mazes or mosaics.
Three tuck rows such as in 236 and 248 would only tolerate elongation if a very fine yarn is in use. Color changes would result in elongated stitches being knit off on stripes in the alternating color, a less often used method than having them knit off on the next same color stripe. Any tuck repeat may also be knit using the slip stitch setting, but while tuck fabrics are usually considered reversible, the slip stitch purl side may be far less interesting.
Tuck repeats 283-292 rely on the correct needles being taken out of work to produce a fabric known as tuck lace. Depending on the machine model, the repeat may have to be flipped horizontally to set up proper NOOW for successful patterning.
Slip stitch settings with all-over pixel units matching those illustrated for tuck may be used in the tuck setting as well, ones with small areas of black cells may also work in weaving. Taking floats into consideration, repeats with rows with no more than 5 continuous black squares may work for Fair Isle.
When using tuck or slip patterns for FI, color reverse the image so the patterning of the white cells occurs in the B feeder and any color changes other than in the ground may be more easily made.
Patterns that look scrambled to the eye are usually intended for use with the color changer and again are accompanied by suggestions for color rotations made in the far left-hand column of the repeat ie in # 386 and 392 where the slip setting is used. The same patterns may be knit double bed, but any fabric changing color every 2 rows needs the first preselection row for row 1 to happen from the right, so adjustments need to be made when using such repeats in Ayab.
Thread lace patterns are best left for thread lace.
Hooked-up floats such as in patterns 408 – 413 use the technique to achieve added patterning on the purl side.
Some weaving patterns ie 427, 432, and 440 could be used for tuck or slip as well. Using repeats in other settings becomes easier when one recognized a few “rules”. Hooked-up floats appear here as well, ie 460, and variations on e-wraps ie 463
As presented the garter carriage patterns do not translate well for other techniques without manipulation ie color reverse or more.
Patterns in the series KHC 512-521 are intended for use with the single bed color changer to produce the striped color patterning, the first preselection row is assumed to happen from the right.
Patterns in the series KRC 522-531 are intended for use with the double bed color changer. The first preselection row is from left to right.
Both sets indicate color changes in columns on the far left of the illustrations.
The remaining patterns are also intended for use with the G carriage.
1/2021 For a variety of reasons it has been nearly a year since I attempted any swatch tests in significant lengths using Ayab. I am interested in exploring long repeats created with small stitch units, and the possible illusion of color variations if any created by the fabric movement. My first design was a dbj heart of Pluto fail because of a problem between the monitor and the chair, the middle value was too close to one of the 2 other colors in the palette, so it did not get knit on the top bed, I did not pay attention, kept on going,  the patterning for only 2 colors appeared correct over more than 200 rows. The second test was of a different repeat in 2 colors. It was knit in single bed FI for the first run and here I am again with the issue I have had in the past with patterning errors in longer knit pieces. The fabric begins to do what I intended, the effect may be more marked if knit at a tighter tension. This is the working repeat, 34 X140 pixels, check if downloaded that the mode does not get switched back to RBC,  here repeated X2 in width, with a 2 stitch border in black on either side (72 X 140), suitable width for a scarf in DBJ. DBJ is a better choice for long pieces since fair isle has a tendency to not stay flat, rolling toward the purl side. The side border is a personal preference of mine. Now that Ayab allows for repeating the patterns both in width and height, such border additions, whether for a single color vertical line or to produce all knit stitches aside tuck or slip center areas are still not possible additions within the program itself There have previous posts on automated lace edging on Brother machines, ie 1, and 2. For anyone wishing to try them, this shows the proper Ayab orientation for the repeat, along with selection errors on my 910 The first preselection row is as always from left to right, the knit carriage, set to slip in both directions when on the right knits 2 rows, preselects for the first row of transfers as it moves from left to right, and lace patterning and selection begins from the opposite side. Extension rails are a must on both sides since both carriages are now selecting needles and each needs to be off the belt while the opposite carriage is in use

After absences from topics, I find it necessary to review them and their categories. This list, for now, catalogs my previous shares on Ayab use specifically, all are subject to future editing
