I am trying to make a quilt for my son and decided I wanted to make the quilt more of a rectangle instead of a square. To do this I want to put pinwheels on point above and below the main square. Ok, I did the math and using my quilt design wizard have found out that to make an 8" square on square pinwheel (to make them look on point) I need a pinwheel that is 5 5/8 inches finished or 6 1/8 inches unfinished. Does ANYONE know how I would be able to make them this size? I haven't even made one of these, but they look fairly simple so I know I can do it, just can't get my mind around anymore math. Thanks to everyone who tries to help me.
