This book is like new, as I only looked through it, bought it....... then didn't use it! My loss, your gain. Learn to knit 2 socks at the same time. The technique explained and illustrated in the book can be used with any sock pattern. There are 17 sock patterns and I have the Errata Sheet (list of corrections to book after it went to print). The patterns are a combo of text and graphs. Book originally sold for $ 16.95, now only $ 8.00. Can be shipped reasonably using media mail option.
