Mary Atwater describes a warp-face pattern weave studied from a Bolivian poncho and coca-leaf bag, which she and a group of weavers reproduced on a harness loom at a Montana summer gathering. She gives the warp color plan and sett (48 ends per inch, 4 per dent in a 12-dent reed), treadling for the dark and light square figures, and pick-up stick directions for an X-figure. She also covers a technique for beating up the dense fabric, possible uses, and the needle-woven braid edging on the originals. The last page has the draft with tie-ups and 6- and 4-harness threadings.
