Cheap and Easy Stamped Coasters made from affordable Bathroom Tiles. This blog shows step-by-step how to make these. Great gift to give for house warming, bridal/wedding, Christmas, etc. So cute and useful!
Easy to do - travertine tile + photo printed on tissue paper - they have made these into coasters but they would be nice on the wall - I would leave a slightly wider edge - you could also experiment with making photo transfers directly on the tile
