Mary Meigs Atwater describes her experiments with jaspé, a tie-dyed warp or weft effect seen in ancient Peruvian and Guatemalan weaving. She explains stretching the weft on a frame (a spool-rack), wrapping and tying dots and dashes to resist the dye, then dyeing, unwrapping and weaving the weft. She recommends weft-dyeing for standard looms, mentions materials that worked well or poorly, and suggests using the jaspé in stripes and offsetting the weft slightly for a softer look. Illustrations show the wrapping method and a tying frame.
