Pomo
"Almost all Pomo baskets, whether coiled or twined, are made upon a foundation of slender willow stems. The only other material so used is hazel, the slender stems of which are employed in the same manner as those of the willow... To the second class of materials, those used entirely for the purposes of ornamentation, belong the beads and bits of shell, and particularly the various feathers, which are found so frequently on Pomo baskets of the finer and ceremonial types."
-S.A. Barrett, Pomo Indian Basketry
