My Peter Collingwood book on weaving rugs has about 500 pages and goes into incredible detail of techniques I'd never heard of. The cover picture doesn't match my edition either, but I can't see mine on here.
I weave occasionally as a hobby, playing with intricate patterns for fun.
Peter was the best. Take his chapter on soumak weaving. Amazing,and not in the half dozen other books I have. Peter compared to other weaving authors is like comparing Elizabeth David to Jamie Oliver, or if you like, comparing Churchill to Teresa May. From the sublime to the ridiculous. (Sorry Jamie! You're nice but you can't write!)
