I'd like to see others note their suggestions about books and other resources for tapestry weaving. I've collected many over the past twenty five years but I'll start with a new book I've just gotten:
"The Thread's Course in Tapestry" by Mette Lise Rossing. You can find info about ordering it at www.billedvaevning.dk
Rebecca Mezoff gave a nice video review of the book at her blog and that's how I became interested in ordering it. In the preface, Ms. Rossing says "...(it) is a 'nerdy' book for anyone interested in weaving images. It can also be used by fabric weavers who wish to develop their decorative skills." The book is jam-packed with wonderfully clear drawn illustrations of many techniques and also had numerous color images of tapestries both old and new, details shown of many. At a quick glance (I just got the book yesterday!) it seems to be exceptionally comprehensive and I'm excited to have added it to my tapestry library collection.
