I thought I would post a little about how I make my glass pendants. There are tons of how to's on this all over the web. But still will post it anyway :)
Ok, so these are my supplies that I start with. I use scrabble tiles, dominos, and glass tiles. I have my images ready to go, as you can see in the picture.
I use Mod Podge matte finish to adhere my pictures to the surface of whatever piece I am working with. Some people just use their Diamond Glaze, or whatever they use, but I found that it was too slippery, and the Mod Podge really gave it stick.
I let the images dry to the piece. Once dry, this is the trick here...you take a nail file, and you file the edges of the image to the piece.
Once you have done that, then you can seal them with your Diamond Glaze and let them dry.
Voila!
