October 1956 issue of the Shuttle Craft Guild Handweaver's Bulletin (Portfolio edition), edited by Harriet Tidball. It is a theory-focused issue on four-harness pattern weaving, explaining twill, extended point twill, overshot and hybrid drafts, with six numbered 'Shuttle Craft' example drafts and drawdowns. Further sections cover weaving-as-drawn-in, overshot profiles, twelve equivalent ways of writing the Trellis draft, and twill selvages. The issue also carries an obituary of Mary Meigs Atwater, news of a Bertha Gray Hayes pattern book and a new Guild business manager, a review of Ulla Cyrus's Manual of Swedish Hand Weaving, and notes on three Portfolio samples (Linoleum, Three Times Three, Trellis).
