Mary Atwater describes the twice-woven rug technique, in which a first weaving of carpet warp and rags or yarn is cut lengthwise into chenille-like strips and used as weft for a plain tabby rug. She gives sleying, warp setting and yardage calculations for a 36 x 60 inch rug. She also gives color-arrangement plans for borders, checkerboard, stripes, diagonal and zigzag centers. Two photographs show an old rug and an experimental sample.
