April 1958 issue of Warp and Weft, a monthly bulletin from Robin & Russ Handweavers of Santa Barbara, California. It includes the editor's column, a profile of the Black family's weaving business on Cape Cod, and a four-harness conventional honeycomb draft in cotton and silk with tie-up, threading, treadling, materials and cost per yard. Two book reviews (Mary E. Black's New Key to Weaving and the Swedish text Smavavar) are followed by classified ads for looms and yarns and a loom and yarn supplier marketplace page.
