I love the Rings that Bind by Cheryl Phillips. Three different size arcs, one come with the book and the others are sold seperately. It goes together very easily and I am doing the quilting in the center on my embroidery machine. It does take alot of fabric, but since it's a QAYG, when you get to the end, its complete. And the customer service from this company is wonderful. I shattered the original template and the book was out of print at the time. I was devestated since I was in the middle of a quilt. The ladies searched and searched to find me another. They finally came up with one from somewhere.
