You have GOT to try this block. It really does go together in 5 minutes - I timed it!
This one is a baby quilt for my nephew. I hand stitched each of the white pinwheels to make the curved edge and I echo quilted the red/white pinwheels formed by the pattern on my mid arm machine. Suzanne's tute is excellent and easy to follow. There are several ways to put the blocks together if you don't like pinwheels.
