I just used some cardboard and cut it 11/2 x 11/2 in. I covered them with white paint and let it dry.Then I stamped on it. I used Mod Podge to glue down the tissue paper. On those 3 tiles I also stamped words on it. Then I used some ink over it and black ink for the sides. I used the Mod Podge Dimensional on those tiles.
On those 2 tiles I used Glossy Accents. There is not much difference, except the Mod Podge tiles seem to warp a bit. I seen the tutorial at: LivArtNow
She used scrabble tiles. Also fun to make.
