I learned about this block yesterday at my quilt guild meeting. It is in the most recent issue of Quilt magazine, I believe. I made these two blocks last night. The original is 10" sq., which is pretty large for me, so I made one half that size also. I don't think I can get it smaller, though, because of the many layers of cloth, but I might give it a try!
The folded and sewn 3D parts of the pinwheel look just like a recent post of a baby quilt, something about Surprise. If I can find it again quickly enough, I may edit it in here. Anyway, hope you like looking at my blocks.
Here is a link to that baby quilt I remembered:
