I've been putting a lot of time recently into developing more "kid friendly" methods of glass fusing. The first method I came up with uses dots of glass. Using different sizes and colors of glass "dots" simple, cartoony characters can be made simply. The trick is, as glass melts it's surface tension starts to pull it into a ball. You can use this much like the gravity to pull smaller dots into larger dots. Here's a panda bear made just with dots of glass.
Arranging pieces just a little differently and adding some orange dots, we can also make a penguin.
I've developed another method that allows me to make complicted shapes in glass that can then be used in fusing projects. The end result is a piece of glass about 1mm thick in pretty much any shape you can imagine. They can also be small, much smaller than you would ever be able to cut out of sheet glass.
These are small enough to fuse onto a pendant or picked up and melted into a hot bead. They're made from System 96 Glass and I could even make them glow in the dark.
I'm currently making a variety of shapes that will be available soon. To give you an idea of price, right now I'm selling a pack of six red hearts for $4. You can check them out here.
