cutting blocks
if I have a pattern I am cutting and make a mistake on squaring up the blocks so I have to cut them from a 4 1/2 block to a 4 inch block do I have to reduce every block on the pattern for the pattern to come out right like I have rectangles and 4x8 blocks and 7 1/2 x 23 and 4 inch blocks so do I reduce all the blocks by 1/4 inch ? help please
