Re Blanket designs...
Just an interesting tidbit... most of the Navajo rug designs we see
are strongly influenced by oriental rugs. The traders in the late 1890's
along the railroad found a market for native weavings, and showed the
oriental rugs to the weavers.... since they were popular at the time...
I always try to help my students see that cultures learn alot from many
sources..... and wonder more and more... what is "pure cultural art" :)
