This book is in a very strange format. Who ever heard of a sock poster? Especially one that is a meter tall. The designs are mostly interesting; all are shown on the poster (currently shown on the cover photo). Two designs are designed for top down and nine for toe up. The biggest merit to me is that the book explains a technique for working instarsia in the round that I have not seen elsewhere. There is also a toe design that makes a left sock and a right sock, but that would fit my toes much better than the standard wedge toe, which is also given.
