Call me CHEAP but...

For the problem of stamps falling off, just use a little Aleen's Tack it Over and Over on the cling part of the stamp and it will stick well! No more falling off! You can find this at Michael's.

Do you have a Xyron Kelli? I have used their double sided adhesive cartridges (which I get one sale at Michaels or Hobby Lobby and use a coupon for) and created EZ Mount-like sheets using it. I read somewhere online that xyron does not damage the cling on cling-mount stamps. LOVE my Xyrons - they are awesome for aplying adhesive to intricately cut shapes in my Cricut as well. GOOD LUCK!!
