Yep, I used Elmer's washable school glue and it worked like a charm - just a tiny bit, a warm iron, and WOW! I realize now that what I didn't really enjoy about piecing was putting rows together and adding borders because of all the pins. This was so easy, and when I went to sew the seam, it was nice and flat. Will definitely have to try it on the next binding.
Would never have tried this without reading it here. :-)
