I agree, Boscobd. The largest one I've done was 44x62. The problem is the quilting "uses up" the front or backing material depending on the way one quilts, so the quilting design may not reach the borders evenly. On this one, I lost 1/2" of backing. To keep from having to shorten the quilt and mess up the design, I had to put extra wide binding tape on the bottom backside. A save is as good as a win to me!
