"The Papago (the most prolific basketmakers in the Southwest) use bundles of beargrass stitched with willow or yucca."
-Bryan and Polly Sentance, Craft Traditions of the World
"The wider leaves of the yucca do not require as much sewing, and the coarser stitch does not allow for very intricate geometric designs; all this saves much time for the weaver and allows an increase in production. Animal and plant forms have become favorite decorative elements. Since it is pounded as it is woven, the surface of the coil of the yucca basket tends to be flatter and wider."
-Charles Rozaire, Indian Basketry of Western North America
