I'm very glad they please you.
Can you show some of the other pinwheels you have received?
I really like the twisted sister pattern, my mom and I made 12 of those quilts for all her grandchildren, and it didn't take us that long. It was before I learned to machine quilt, so we tied them all. Very fast with three people tying them, we used the international knot, so there were no external strings.
