There is a beautiful picture of a quilt by Natalie Sewell in her book:

There is no pattern, but her quilt is used as a teaching example in the book and she tells how she did it. I love her quilt. I tried finding a picture of it, but wasn't able to. You'd have to find the book. Maybe in the library? Or maybe I could scan it and email it to you. PM me if you'd like me to give it a try.
