I just received my copy of "The Weaver's Idea Book" by Jane Patrick and I would strongly encourage anyone interested in exploring the capabilities of the humble rigid heddle loom to seek out a copy. There is a short chapter on the workings of the loom, then the text dives right into plain weave, finger controlled weaves, pick-up weaves, warp- and weft-faced weaves (including Krokbragd), and two heddle weaves (including double weave). The book is hard cover with a spiral binding so that the pages stay flat when the book is open. Jane and Interweave did a great job on this one!
