Can I create a removable window cling?

Yes, Gallery Glass can be peeled away from most surfaces once dried. To remove the design, use a craft knife or the Gallery Glass scraper to peel up the border starting in one corner. Slowly peel the entire project from the surface, working toward the opposite corner from where you began. Most projects will peel off in one large piece. Store the project on wax paper to prevent sticking and simply reapply to the desired surface when ready. NOTE: If applied to polystyrene or Plexiglass, Gallery Glass dries to a permanent finish and cannot be removed.
