Personalized Photo Coasters. All you need are the 5 items pictured above. Cut the photos to fit the square pieces of wood (which btw are under a dollar at Michaels) Apply enough Mod Podge to the wood so that the photo sticks, allow to dry for at least 10 minutes. Lastly, apply a coat of Mod Podge over the photo and allow to dry. Voila ! Don't need a coaster ? No problem, put a self adhesive magnet on the back and slap it on the fridge !
