Knight's brand of knitting and purling only vaguely resembles the art form practiced by millions of grandmothers. Although she uses needles, in her projects yarn is a variable; it's often replaced by such diverse materials as ribbon, wire, strips of plastic and gauze. And the patterns that do use yarn go way beyond the usual patchwork scarves and lumpy sweaters. The 20 patterns here range from simple to truly byzantine. Beginners might try their hand at the Woven Woolen Rug, which employs remnants of yarn and calls for a basic stockinette stitch. The Aran Armchair Cover, on the other hand, will probably intimidate newcomers, as it requires knowledge of the reverse stockinette stitch, seed stitch, raspberry stitch, twisted stitch, diamond panel and fat cable. To her credit, Knight (Simple Crochet; Simple Knits for Little Cherubs; etc.) does explain techniques up front and uses color photographs to demonstrate steps. If nothing else, her book will encourage knitters to think beyond hats and mittens, and consider using knitting techniques to create wall hangings, dog coats, wire bowls, napkin rings or boudoir slippers.
