Pinwheel help
I need help. My mind just does not operate in mathematical mode. I want a 6 inch pinwheel in my quilt. I want to cut out 2 squares and sew around the perimeter and cut it corner to corner. There's probably a name for this but I don't know what it is. I tried cutting 6 1/2 inch squares but when I put the pinwheel together it was 7 5/8 inches square. It made it beautiful pinwheel but it's too big. How did this happen? What size do I cut my squares to get a 6 inch square? Am I making this too difficult?
