Oh no wighrose! Bleh I hate when that hapenes. I faithfully cut 5 WOW 2 1/2 inch strips into 2 1/2 inch blocks for an entire quilt top only to find out they needed to be 2 1/2 x 3 1/2 in. We need more chocolate and sweet red wine I think.2 You should have seen my face. I kept on checking the pattern to see where in the world I was using all those 2 1/2 inch squares. No where ofcourse.
