Geometric shapes on ribber fabrics formed with tuck stitches 4

The term brioche in knitting is often used loosely in any references to tuck stitches. Here the term refers to vertical designs specifically produced with hand techniques, moving groups of stitches on the top bed.
Designs may be worked in single colors, or with more complicated planning, they may be executed in 2 colors.

Other explorations of the use of tuck stitch settings in 2-color double-bed every needle rib fabric began with attempting to create a solid color shape on a vertically striped ground in Geometric shapes on ribber fabrics with tuck stitches 1  Another simple shape was programmed, and varied carriage settings on either or both beds were explored in Geometric shapes on ribber fabrics with tuck stitches 2; knitting with 4 carriages. Geometric shapes on ribber fabrics with tuck stitches 3  uses self-drawn repeats and  multiple colors. varying carriage settings while using only 2 colors  Lace transfers meet fisherman rib in 2 colors on Brother KM 1Lace transfers meet fisherman rib, 2 color ribbed brioche on Brother machines 2 , one of several swatches. 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 forming the more familiar tuck rib surface. Mac Numbers offers the opportunity to hide either/ 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 one 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, As described in previous posts, in 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, requiring introducing or removing stray lines or secondary shapes.
The cam setting options: In a two-color brioche, when no needles are selected on the top bed (white squares), the top bed will tuck every needle; the ribber is set to knit. 

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.
After each transfer, push all needles involved in the transfer and 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 are not hung up on gate pegs as stitches move across the bed, while still being loose enough to knit off properly.
A first repeat, plotted in a spreadsheet including borders Here groups of columns are eliminated to bring the shapes close together The yarns used are white 2/15 and red 2/10 wool.  The latter is coarsely spun and tends to split and occasionally not properly knit off, resulting in the specks on the white columns on the reverse, making it a poor choice for final projects.

Studio/Silver Reed machines published some designs for pile knitting in their punchcard volume  

The inspiration page   The #14 24X42 repeat used in this sample was color-reversed before being downloaded to the 930  checking tiling punchcard machine users would punch all black cells. The pattern is worked with end needle selection canceled, the knit carriage is set to tuck in both directions and the ribber carriage to knit in both.
The first and last needles in work are on the ribber bed.

The #13 design, is composed of 24X16 segments  repeated X2
The 16X32 rendered double length to 24X32 was used to knit this slip-stitch double bed fabric  The 24X16, file color was reversed and this 26X32 file added black pixels in width for more definition of the shapes The yarn used is a 2/20 wool, so thin that there is less definition between the two stitch types and enough open space between the stitches to show the surface beneath the swatch, which measures 13.5 inches in width, 7.25 in height A DIY attempt at a large scale design: the 24X38 was found in Pinterest, published in 2018 and credited to a Russian site.

The yarn used in this swatch is a 2/20 coarse and unevenly spun wool, which leads to the variable moiret-like bleed-through of the fabric colors behind it.  The same yarn was then used double-stranded. Some spots were harder to knit than others due to changes in ply quality resulting in snags in texture as well. The shapes are more clearly defined, the largest shape measures 7.5 inches of the 11-inch swatch width and 3 3/8 inches in height. This swatch began with a 25X25 pixel file, processed in Arahpaint drawn in repeat using the random >preview option until a final version was chosen and rendered double-length. Brush fill was used to expose every other row, and the resulting 75X150 file was color-inverted for use with the tuck setting These knits produce a subtle texture easily on both sides and lie flat.

This design is not suitable for this exercise but is another illustration of the horizontal/vertical striping that can happen when large-scale designs repeat proving the need to tile the patterns before knitting them to visualize whether they meet one’s personal preferences
