This is a knitting pattern book. The pattern makes the following sizes: Girl's USA 5/6 (X-Small), 7/8 (Small), 9/10 (Medium), 11/12 (Large), 13/14 (X-Large), 15/16 (2X-Large). The instructions are detailed (no graph), color coded, easy to follow, and in large print. This gorgeous dress whips up in no time because it requires the use of #9 knitting needles (not included) and worsted yarn (also not included).
