I've been making a top with pinwheels, but now I don't know how to quilt it. I remember that once I've seen a quilt were the pinwheels were quilted curved, and that made them look even more as if they were spinning. Don't know how to do that. Anyone there who could help me on this? Or maybe some other interesting ways for quilting the pinwheels? I want to machinequilt it.
