The Sock Project: Colorful, Cool Socks to Knit and Show Off

Get your hands – or, your feet, I suppose – on what might actually be the best sock knitting guide of the last bazillion years: Summer Lee's The Sock Project. 

Organized to be a self-education course in sock skills, this book walks you through 12 levels of sock projects designed to build a strong foundation atop the basics; you'll learn an extensive variety of heel and toe variations, then gain skills in colorwork, lace, cables, and more. You'll be designing your own fantastic footwear by the end of this book!
