I thought that was an interesting article, going into history both good and bad. Is one of the hard things about quilting being mostly a western art form. On my trip across the states before we moved, we went to the Dignity statue. Thought you might like this link:

And speaking of Native influences, let's have three cheers for the Seminole Indians who took to the concepts of machine quilting and strip piecing as soon as there were machines to do piecing on!
