April 1957 issue of the Shuttle Craft Bulletin (Portfolio Edition), the monthly bulletin of the Shuttle Craft Guild. Harriet Tidball's lead article sets out 17 treadling sequences for texture sampling on an M's and O's threading, including twill, huck, spot weave, summer and winter and overshot. Trude Guermonprez begins a history of tapestry weaving, covering looms, technique and Jean Lurçat. Tidball also writes a how-to on threading the loom, Natalie White describes woven tweed car coats, and Boris Veren and Marie Murelius review a book of Pre-Inca textile plates. The issue ends with the Loom-Side Market, a section of loom and yarn advertisements and a services directory.
