Found these books at Goodwill last night. Got them 1/2 price at $1.50 each. The set should be 16, but guess what? book 1 is missing. I really want to learn to crochet and knit and the first course is in book 1. I glanced through them last night and I think I'll use them. They are from 1986. The patterns for the knitting and crocheting are timeless.
