Yay you! I use Elmer's for piecing too, I remember the first top I made with it, I told hub I was never ever going back to pins, perfect intersections and no ripping, I was so happy. lol I just use a tiny bit also and when having to press open seams they pull apart pretty easily but if it's not I wet the seam allowance a little to release the glue and use the (non-sharp) back of the seam ripper to gently open it up.
I also glue my binding raw edges together (and only iron to dry the glue on the raw edge so I don't press a crease in it), it keeps the binding from getting little puckers in it from the pressure foot pushing the top layer ahead of the bottom when I sew it down. Love Elmer's.
