Boston, try laying your ruler on the fabric so that the whole of the mark for the width to be cut off, is on the fabric. It will make your cut a tiny bit fat but if you are consistent with that measurement, it just might give you enough to get your block to the correct size. I have a friend who never presses with an iron until her block is finished. She only finger presses. She is an amazing piecer. You might want to try that too.
