March 1957 Portfolio edition of Shuttle Craft, the monthly bulletin of the Shuttle Craft Guild, edited by Harriet Tidball. The issue centers on variations of the M's and O's technique (balance units, odd-numbered rep ribs, honeycomb fabrics, the hollow square multiple-harness pattern, and sport coat tweeds). It also reprints Mary Meigs Atwater's 1941 article on tapestry rugs in an ancient Peruvian design, and includes Mary E Black's step-by-step article on working out an unknown Swedish overshot/daldrall draft. Regular features include a loom-language glossary, book shelf notes, an editor's letter, and the Loom-Side Market with loom, yarn, and service listings.
