Excerpt from the Thaw Catalog: The Chumash peoples of the southern California coast were brilliant artists. They made excellent baskets, some with very complex designs, inlayed their ground stone implements with patterns of shell set in asphaltum, and made large plank boats for deep-sea fishing. The baskets were coiled with two or three stiff stems of deer grass, often with an additional bundle of grass leaves. Sewing was done with splints of sumac and patterns were created with orange and deep brown juncus. (c.f. Bedford 1980, p.52; Lopez and Moser 1981, p.206)
