I have been reading an article about organizing your stash and came across a line that said, basicallly- a finished square is 1/2 inch smaller than the original cut square. So if I have a 4 inch square, taken out of my red box, after sewing it to other squares, it should measure 3 1/2 inches - that is using 1/4 inch seam allowance. The accompanying illustration has the original square attached on all 4 sides.
****Why is the finished square only 3.5 inches and not 3 inches if you are sewing all 4 sides using a 1/4 inch seam allowance? After all, you are taking 1/4 inch off all 4 sides and 1/4+1/4+1/4+1/4=1***
I know math is not my strong suit, but am I that weak in it?
