Ok, here's how I do it, but you have to promise to be careful! I take the back and put thumb tacks thru the places that I want to match with the front. Insert the tacks from the right side of the fabric. Lay the backing down, the points will be facing up. Lay the batting down, then the top. It's easy to use the tacks to align the top with the backing using the tacks. Put little erasers on the tacks to keep from sticking yourself.
