OK, next question....what if I leave my batting about 1/2" larger than the square and the backing 1 1/2" larger, so that when I fold the flaps less of the block is covered, thus making my "sashing' larger?! Have you tried something like that? I am affraid trimming the batting then turning the fabric will make my quilt smaller in the end. See I have 24 blocks that I want to divide to make two quilts, and want to use the sashing to make them larger. Does any of what I am saying make sense??? Thanks
