If you've been quilting for a while you may remember Doreen Speckmann. She published a great book called Pattern Play in 1993. It's all about making your own patterns with a few simple blocks. I love the book and have kept it in my library and I reference it often. It's still available as a Print on Demand book.
Today's design is based in a quilt in the book called Sally's Quilt. I've done 6 versions. What do you think?
