Nearing the end of another year, reviewing previous drafts, I find myself coming across posts that were never quite completed or published.
This content began to be brought together in 2022.
The term brioche in knitting is used loosely at times in any references to tuck stitches. Designs may be worked in single colors, or with more complicated planning, they may be executed in 2 colors.
Some patterns are fully automated, with the knit carriage set to tuck in both directions, the ribber set to knit in both, others are worked as a tubular tuck, and lastly, some require frequent changes in cam settings in either or both beds.
My explorations for the use of tuck stitch settings in double bed every needle rib fabrics began with attempting to create a solid color shape on a vertically striped ground in Geometric shapes on ribber fabrics with tuck stitches 1.
The arrow marks the spot where both colors used were picked up from the changer. C1 and 2 show indicate cam setting changes used in the last part of the swatch.

Here, a simple shape was programmed, and varied carriage settings on either or both beds were explored Geometric shapes on ribber fabrics with tuck stitches 2; knitting with 4 carriages.
Geometric shapes on ribber fabrics with tuck stitches 3 explores self-drawn repeats in multiple colors.
Added samples and files in the subsequent post New double bed swatches based on published sources of inspiration 2

These are advanced, complex fabrics. The repeats for 2 colors can grow exponentially in length.
Returning to designing suitable repeats, beginning in a spreadsheet: grey vertical lines represent stitches on the ribber, which will force apart stitches created on the top bed, creating the more familiar tuck rib surface. Mac Numbers offers the opportunity to hide both columns and rows. In this instance, with the 10 grey columns hidden, one begins to get the sense of shapes and movements needed on the top bed
Working toward a repeat for knitting the shapes in a single color, imagining the location of eyelets resulting from stitch transfers,
I used two repeats, adjusting the first repeat to vary the resulting shape slightly
A 11X30 repeat mirrored horizontally for use on my 930, tiled twice horizontally before programming and downloading, used as a 23X30 single motif to obtain a matching border on each side, ![]()
A 9X28 repeat, my second try, programmed as a 20X28 single motif, ![]()
When knitting using only one color, the machine is set with the main bed tucking on every needle in one direction, followed by knitting on every needle as it returns to the starting side, the ribber does the same but in the opposite direction. It is a circular tuck, also referred to as fisherman’s rib. A slight shift in patterning may change the outline of the desired shape, introducing or removing stray lines or secondary shapes.
The possible cam setting options: 
In two-color brioche combined with hand-transferred stitches, the main bed is set to tuck in both directions, white cells tuck, black cells knit.
Brother machines preselect needles for the next row with each pass of the carriage, so on even-numbered design rows, as the carriage moves to the opposite side, all needles will form tuck loops on the main bed. The next row will be preselected, with some needles now back in B rather than D position.
With an appropriate transfer tool, move the stitches on the nonselected needles to the adjacent selected needle to their right after pushing it back to the B position. After each transfer, push all worked needles and their stitches, as well as the now-empty needle, to the E position.
As the carriage returns to the opposite side, an all-knit row will be completed. Several tension adjustments may be needed to ensure loops do not get hung up on gate pegs as stitches move across the bed, while still being loose enough to knit off properly.
Planning a fully automated design, reducing the ground, and staggering the color of the shapes. In these knits, the colors in the background form clear vertical lines:

A half-drop tiling error was revealed,
and the file was reduced to 23X44.

Using the 24 stitch repeat executable on a punchcard machine as well, planning to knit the test swatch on 72 stitches,
anticipating what will happen with color of the alternating pairs of rows forming the shapes, noting that the total number of rows is an odd multiple of 4:
adjusting the repeat to 48X40with the total rows an even multiple of 4,
tiling check, 72X80
the stitches composing the all the shapes will knit in the same color
The pattern, tested in thin yarns reveals the stitch structure even more. That said, the dark color was 2 thin yarns threaded on the same side of the mast. At one point, one of the 2 began to loop around needles, causing a carriage jam and a bent needle hook, hence the short height of the sample.

Combining knit carriage needle selection with racking




























































































When needles are selected on the top bed (black squares), the ribber is set to tuck in both directions.
Brother preselects needles for the next row to be knit, on rows with partial selection and some needles in the B rather than the D position, with an appropriate transfer tool, move the stitches on the non-selected needles to the adjacent selected needles to their right after pushing it (them) back to the B position.
