Not solving original problem, but asking about above comment.........
I thought the opposite..bottom eats more than top...that is why if you have slack in one of the two pieces, but the baggy one on the bottom and it will then be evened out when sewing.......anyway, that's what I do and it works..maybe just my machine.......or me
