Ok, I did scant 1/4 inch seams this morning when I made a block for a swap I am in that requires 12 1/2 inch blocks be exact, I am wondering how these tiny seams are going to hold up under heavy use? Would'nt it be better to cut a larger 1/4 inch extra so as to be able to use the standard 1/4 in seam? or would this distort the blocks? maggiebb
