Inspired by the shoulder bags that are part of the Mayan Indian man's traditional outfit, Norton presents tapestry crochet, a form of sturdy crochet worked in two or three colors. The basics of crocheting with either the right or left hand are described and accompanied by clear drawings. To facilitate designing, Norton developed a graph paper that represents crocheted stitches; the elements of the grid resemble rounded shingles or overlapping bird feathers.
