Drop stitch lace, 2 colors per row, japanese machines

This is an attempt to duplicate the results of Passap tech 185 on knitting multiple colors per row drop stitch “lace” fabrics. The method may be used for more colors per row, expanding the repeats accordingly to the number of colors per row X 2 for each motif row. For example, here 2 colors per row are expanded to 4 rows for each color in length, 3 cols per row would need to be expanded to 6 for each design row
This fabric widens considerably when completed, so top and bottom edges, cast ons and bind offs, may need special consideration and planning

The method for swatching: cast on for every other needle rib, knit 2 circular rows, followed by one-row rib, transfer all stitches to the ribber. For an open stitch cast on directions and photos see later post
Set machine for every needle rib, COR, an extra needle in work at each end on the main bed; cancel end needle selection (KC II), make the first pass toward the color changer; needles will be selected in pattern.
The ribber is set to knit every needle except for circular cast on rows,  the main bed to slip < —– > throughout; I put a piece of tape at the edge of the knit on each side, just in front of needle butts in A position, to help keep from accidentally moving extra needles into work after dropping whole rows of stitches
COL change color, as carriage moves to the right, selected needles will pick up stitches on the main bed, creating the long stitches when dropped, while the next row of pattern is selected, so by the time the carriage has reached the right side of the machine, needles will have flatlined; using any convenient tool (I use the edge of a piece of garter bar or cast on comb, bring needles involved in patterning out far enough to drop stitches, check that all needles are empty, push needles back to B position: COR
COR: as the carriage moves to the left again toward color changer, ribber only will knit all stitches (does so every row), needles will be selected for the next row of long stitches, selected needles are not knitting. Colors are changed every 2 rows

The emerging pattern can be seen, and to be noted is the elongation factor involved as in many color separation DBJ fabrics

For a later review of cumulative posts on the topic see: revisiting drop stitch lace 

For design method for staggered shapes in drop stitch see Ayab software related post The difference from those directions for knitting without the particular software: in other electronics, a single repeat in both height and width is adequate. In machines such as an unaltered 910, the first preselection row can be from right to left, so no accommodations need to be made for shifting the last row to the first of the design repeat. For machines accepting electronic download,  program repeat with first design row containing black squares in it, adjust the spacing between repeats as preferred. This particular version is 80 stitches wide 

In an unaltered 910 with the ability to double the width of the programmed repeat, mylar users are not excluded from exploring a similar fabric. The repeat above may be rescaled to half the width,  drawn that way, and then use the twice as wide built-in feature. Gimp does an “interesting” thing when scaling this design to half-width, note the right side of each repeat contains an odd number of squares, the left side an even one. The repeat may be used as-is or redrawn, adding or eliminating black squares if symmetry in each shape matters.  Paintbrush produces the same image, mirrored.

The explanation: further analysis of the original design reveals the fact that some of the pixel numbers in the design black square blocks are uneven in width. In this instance, 3.5 is half of 7, and half pixels cannot be rendered, so the software assigns the split to 4 and 3.

  1. Fabulous! I can’t wait to try it. Thank you so much for these very detailed instructions.

    I have one question. After the first pattern row, COR, you say that “the needles will have flatlined”. What does that mean, exactly?
