A study booklet prepared by Marian Powell for the Des Moines Weavers Guild on Summer and Winter weave. It covers unit structure, blocks and profiles, tie-ups, and weft variations. It then gives many treadling methods, including classical, six-shot rotation, one-and-one, four-and-four, two-and-two, opposites, huck, sequence and twill textures, lace texture, honeycomb, 3D, eyelashes, novelty, polychrome, part polly and spider webs. It closes with warp suggestions and references to sources such as Shuttlecraft Bulletins (Tidball), Master Weaver (Zelinski) and Frey's Designing and Drafting for Handweavers.
