Which material did plains indians use to make bags

They used beads and beans to make thier bags. How creative??!!!

There were two very basic styles of American Indian bags: soft pouches, made of tanned animal hides (usually deerskin or elkskin), and parfleche, made of stiff rawhide. Some modern Indian artists blur the two traditions by creating tanned buckskin purses with rawhide siding on the inside to give it the boxy parfleche look. Regardless of their material, Native American bags were often painted, beaded, or quilled with the characteristic tribal designs of the craftsperson (usually a woman) who made it--particularly if the bag was designed to hold something sacred, such as a medicine bag or tobacco bag, or was being made as regalia for a fiance, daughter or son. In recent centuries the great specificity of Indian bag design began to change, with the development of the catch-all "possible bag" that could be used to transport any of one's possessions. Today, both specific and possible bags are still being made and decorated by artists from many different tribes, and they continue to be a lively and practical part of native life, much more so than baskets or pottery (which are generally treated only as artwork these days). Since non-native women also like to carry a purse or handbag, Indian bags are commonly made as trade items today as well.
