This is great because the connection between the Oglala and quilting is strong. I'm a native South Dakotan and have done lots of research on this.
While not originally a native craft, Morning Star quilts (some call it the Lone Star) replaced buffalo pelts in the 19th century. As most are aware of the buffalo started to disappear at the same time reservations started to appear. Missionary people started to teach quilting to the Lakota and the craft adapted to become part of their giveaway custom. A giveaway was and is a beautiful tradition where a family gives away food, clothing, horses (back in the day), and now quilts (formally buffalo pelts) to honor someone's life (funeral) or an important event (birth of a child). When I was in high school during the state basketball tournament, one of the teams gave a beautiful star quilt to their MVP player. The tradition is to drape it across the shoulders of the recipient. When I graduated from college, several tribal members wore star quilts when they received their diploma. The colors can be symbolic (red, white, yellow, black) or artistic. If you every get to SD, stop at
Dignity and admire the quilt she holds.
A Morning Star can make a perfect baby quilt. You would follow the pattern of a Lone Star quilt. I've made a few.
If you want to do more research about this tradition, I can recommend a great book:
Morning Star Quilts.
