I am struggling to make a perfect 12.5 inch square. I am very careful about my cuts and my 1/4 inch seam, but it still seems to end up slightly less than 12.5 inch. It ends up about 12 3/8". What am I doing wrong? Do I need more of a "scant" 1/4" seam? Do I need to adjust my pressing?
Is another option to just square up all the squares to 12 3/8" and call it a day?
Thanks for your help!
