Image on the back of Cling Stamps
You can STAMP the image on the Cling side of the foam w/Staz-On. But I've never been able to figure out how to line it up when attaching the stamp.
Tack It Over & Over - If you apply thick layer, or don't let it DRY DRY DRY - it comes off, and ADHERES to your acrylic block! Used a whole bottle of UNDO cleaning up my stamp cases, and blocks. I might try the watered down idea.
