Interesting article on how missionary women taught native American women the craft and art of quilting, and how the Native Americans made a lot of them their own. Of course, each nation has themes that have meaning for them. For instance, the Plains Indians prized buffalo or bison and horses; whom they depended upon for the hunt. Southwest tribes featured many popular patterns of squash blossoms, thunder and lightening, etc for their art themes. Depending upon her nation or tribe, you would pick a them from that group.
What a thoughtful and endearing gift you are considering.
