Here are some more items that I found interesting at the Detroit Institute of Arts.

Native American doll:
This one is not a great photo but I want to share it anyway.
Native American bag:
I know that people around here (in the midwest) used deer toes to ornament items they made. They also used them to make rattles. The ornaments on this bag are puffin beaks. I guess that it is a matter of using what is available where you are. Interesting, to say the least.
