Very cool!!! I've often spun the seams on parts of a block, but never the whole one. I've always used pins or just "finger pinned". I do think I'll try this, but still using pins. Glue basting would be way too time consuming for me. Guess I'm not quite that much of a perfectionist. As a hand quilter, I sometimes want seams going in certain directions for ease of quilting. Guess I'll need to keep that in mind too.
