Remember that these measurements are for the 4 square you get - NOT the finished pinwheel.
2" squares = 1" HST
2 1/2" = 1 1/2
3 1/2 " = 2"
4" - 2 1/2
5" = 3 1/2
6" = 4
7" = 4 1/2
8" = 5"
8 1/2 = 5 1/2
9" - 6
10" - 7
I did find it easier to trim all my corners after I pressed when I was making small size for a 3" finished pinwheel.
