This is how I did it. I got some thumb tacks and put them thru the points that I wanted to match on the backing. Seems to me I also put a small square of painter's tape over the head of the tack so it wouldn't fall out when I turned it over. I put the backing on a work surface, carefully smoothed the batting over, then carefully put the top on, using the tacks to match appropriate points. Watch that you don't lean on the quilt with those tacks sticking up!!! I then pinned it & quilted it on my domestic machine.
