Known among the guilds as the hand weaver’s bible, this book contains an impressive and wonderfully rich collection of 4 harness patterns with large, easy to read illustrations alongside the drafting patterns it takes to achieve each one, as well as multiple variations for each draft. Clear, concise, easy to follow if you understand how to read the weaver’s “cartoons” as they call the treadling patterns, but they are so intuitive you could almost use this book to learn from.
