BASKETRY
"Native people from this region excel in basketry. Weaving and use of baskets has always been a main element of the cultures of California tribes. Our baskets are of the twined, woven type and are tight enough that they can hold water for cooking. These tribes make a wide variety of baskets from daily use such as baby baskets, collecting vessels, food bowls, cooking items, ceremonial items and we also make basket caps, which are worn by both women and also men, if open weave."

Personal note: my grandmother lived in this area for years and collected the local baskets. The baskets are now with one of my brothers, but I have two small ones.
