Generally when I decide to explore a fabric unfamiliar to me, I begin obsessively gathering information which at times can amount to an act of procrastination. I like to solve the different kinds of resulting problems, am involved with the techniques, and attracted the complexities of the resulting structures and design. As much as the main fabric pattern, edgings in lace items can make an important contribution to the finished look. Borders with shaped edgings appeared in very early Brother punchcard books. Typical graphs seen in hand knitting reference books were provided for the on machine hand technique. “Brother Fashion” volume 4 included the graph and instructions for a shaped edging on a blanket, Tessa Lorant published a small book on edgings (1981) that included some punchcard designs for such edgings as well. In her usual kick butt fashion Susanna Lewis included a pattern in “Machine Knitted Guide to Creating Fabrics” (1986) that took the process a step further by using slip selection with the knit carriage to automate the shaping process. Working out the separation required for the repeats can be doable but quite time consuming. A “modern” publication on the latter subject can be found here.
