Cuboid: a box-shaped object with 6 flat sides and all right angles; also called a rectangular prism.Cuboid is a beautiful 2 color slip-stitch op-art cowl that can be worn as a regular cowl or pulled up to become a hood. The technique used to create the fabric, slip-stitch knitting, is a wonderful way to produce beautiful colorwork patterns while still working with only one yarn at a time. The Conic Pattern purposefully varies the location of the slipped stitches in order to produce a combination of vertical, slanted and curved lines. This creates the “optical illusion” reminiscent of the Op-Art movement from the 1960’s.Cuboid is one in a collection of 4 different op-art patterned cowls based on geometric shapes each of which has a different border treatment. The cowls are shown in three different Plucky Knitter yarns: Cashmere, Bello and Primo Fingering, each containing enough cashmere to feel fabulous against your skin.The designs can be knit either as hoodie cowls or neck
