The photo bead contest going on right now reminded me of these cool pendents I made a couple years ago after visiting Prague. They were pretty easy and a great way to remember my trip!
All I did was cut up photographs into small squares(the cityscape was altered and then printed out on computer photo paper, and the graffiti one is an actual photograph, so either way works). Then I rolled out some polymer clay and used the photo pieces to cut beads a little bigger than the photo. I made a small hole for the jump ring and then baked the clay. After the clay cooled, I glued the photos on and then covered them in polymer clay glaze. Once they dried I attatched a jump ring and strung them on necklaces.
Simple and unique!
