Weaving...looks like you could do something with weaving, especially circular weaving.
Myths..I think there are some myths...check it out..especially with Native Americans, and Greek mythology
Kiss of the Spider Woman is a musical.
I am looking for any art lessons anyone has done relating to spiders. I am taking a class this week and have to relate spiders to all areas especially art and music and would appreciate any ideas. Thanks ---
