Knit tubings/ cords of all sizes have been cropping up on runway photos, interlaced with cables, woven basket weave style, and as the “yarn in giant knits”. My category sidebar has link to my compendium on subject (Jan 30, 2012), written nearly a year ago, the making of the cords, and some published references. Additional ideas: in wider trims where a single knit stitch is required on the slip pass because the cord is wider than 4-5 stitches, and/or a flatter, single bed cord is required, one can play with a punchcard for the needle selection. Anywhere there is a punched hole in a blank row, the resulting selected needle will knit when the carriage makes a slip pass on that particular design row. Brother machines do not require a whole card to be punched for such trims, since the option exists for controlling the slip facility for single rows by selecting only one of the part buttons. The machine will skip white squares in the direction of the pushed cam button, left or right, and knit every stitch traveling in the opposite direction. A punchcard repeat to serve the purpose:
if multiple knit stitches on slip rows are a consideration, in the image below the dashes and dots are representing needles in work, and width of trim, the black dots themselves also the punched holes in selected area for trim
a variant across a row, with 3 stitches slipped in between knit ones
the punchcard repeat for a machine such as studio, where cam operation is different, the following would need to be punched for the required minimum punchcard height
Open tubular knitting using the ribber is possible in nearly every width. The wider the cord, the more it will want to flatten. Wire, various cording, and plastic tubing may all be inserted into the tubes if more sculptural forms are the goal.
An added note: the easiest cord is a narrow knit strip, knit on at tighter than normal tension, which will roll into itself, helping it retain its shape and in turn be substituted in many of the fabrics using icords. For wide strips that need to bend and curve, ribbed strips my work, particularly if knit in english or half english rib. Such ribbed strips may be braided flat, stitched together and in turn applied to sweater panels at their edges, center fronts, etc.
