Like most knitters, I like having a range of sizes in a pattern. From babies to adult, this leaflet does just that. It also is done in two yarns: worsted and sport weight. With the many yarns availble in wool, blends,acrylic, cotton, etc. You will never lack for a great sweater to knit: long sleeved, short sleeve, pullover, cardigan, vest, plain, intarsia, stripes. The list of choices is limited only by your imagination!
