Mary Meigs Atwater describes a tapestry weave adapted from an ancient Peruvian textile, in which the weft follows the contour of pyramid and arc figures rather than running straight across. She gives instructions for a small rug or chair seat: carpet warp threaded three ends to the heddle, counting and marking warp ends, building the pyramids, arcs and inverted arcs, and using a Navajo-style wooden comb. A color diagram, a sketch of the comb, a figure showing how the shapes are built up, and a primitive loom illustration accompany the text. A postscript by Harriet Tidball comments on the cover photograph and presents the design as a beginner's introduction to tapestry techniques.
