May 1970 issue of Warp & Weft, a monthly published by Robin & Russ Handweavers of McMinnville, Oregon. It contains the editor's column, a note on the cover photograph of a wall hanging with wood slats and elliptical heavy weft shapes, and a review of Malin Selander's Swedish Swatches, Blue Series. The main project is Yellow Diamond, a 4-harness herringbone twill for suit or coat fabric in 2/18's worsted, with tie-up, threading, 40-shot treadling, reed, warp length and cost figures. A second project gives a plan for a seamless tubular jerkin woven as double weave with plain-weave treadling. The issue closes with classified ads for yarns, wool, card-weaving supplies and books, and a page of advertisements.
