November 1972 issue of Warp & Weft, the monthly newsletter of Robin & Russ Handweavers in McMinnville, Oregon. Editor Russell Groff reports on a yarn-buying trip to England, Scotland, Switzerland and Germany, describes the cover tapestry photographed at a Southern California conference, and reviews Alma Lesch's book Vegetable Dyeing. The weaving feature, "Op-Art," gives a four-shaft threading, tie-up for counterbalance and jack looms, a treadling sequence (56 shots per repeat), and warp and weft details in red, white and navy worsted, with sett, width and cost per yard. The issue ends with a list of ten books on weaving, lace and dyeing sold by the shop, plus classified and display ads for yarns, bobbins and looms.
