I think you'll find that having different types of adhesive helps. I use a wet glue for the tiniest pieces if I am completing it right it away - -a zig pen. If I am not finishing it immediately, I stick all the pieces that will fit in the X xyron. I use either my ATG or glue stick or the bigger xyron -- the 500 for the larger pieces.
THe glue boogies from the xyron have been driving me crazy, so I have been avoiding it. Okay to deal with if you are making one thing, but I tend to make multiples and it becomes a time consuming, no fun, PITA.
