2 1/2 finish size half square triangle's
I was making a maple leaf block table runner and cut most of the fabric. The finished size of the squares are 2 1/2 inches and the directions called for making the half square triangle's to be cut 3 1/4 and they came out to large. I did cut them down but really hate that chore. What size square should I have used to end up with a 2 1/2 inch block? Thank you, I'm just math tonight.
