If you only buy one sock knitting book, it should probably be this one. It includes everything you need to get started, including illustrated instructions for casting on, knitting in the round and binding off. There are sections on the history of sock knitting and the anatomy of a sock and it includes 25 knitting patterns for socks. The best bit though is that it includes two sock ‘recipes’, one for top down and one for toe up socks, which will allow you to design and knit your own socks in any yarn that you choose. There is also a pretty decent stitch directory, giving plenty of options for both the cuff and the body of your socks.
