Here is a photo of a 4 inch tile that I made into a keepsake. I copied a 3.5" x 3.5" photo onto a piece of white tissue paper. I taped the tissue paper to a piece of cardstock and fed it into my copier. I brushed a thin layer of mod podge on the tile and put down the photo. I carefully brushed a thin coat on top of the photo. I added two more coats, letting them completely dry in between. I sealed it with a spray sealer and then put sticky back cork on the back. I made these for my daycare parents this year for Christmas.
