I bought these cool metal tins that I think are supposed to be flower pots, but I decided to make them frames for some mosaics. The opening is about 4" square and about 2" deep, but I think the tins frame the mosaic well. I made the heart with wings out of paper clay using a mold I made. The mosaic include buttons, sequins, beads and mosaic tiles. I put the heart on a wood block to make it higher than the background mosaic. It looks fabulous and I plan to make some more as I have five more of these tin "frames".
