Early this month, I took a fused-glass jewelry class. I have never done anything like this. We selected glass, cut it, stacked it, etc. We had the option of making pendants, earrings, bracelets, etc. I made 5 pendents. This is was relaxing and fun! Four of them are dimensional - stacked. The largest one is smooth. You do this by laying a piece of glass over the whole thing, once it's put together. They are then fired in a kiln.
Both my daughter and my daughter-in-law received these for Christmas this year. I love to give something one of a kind and made with love.
Next time, I might try making quilt block shapes. Hmmm............. might be hard to get the symmetry thing going on tiny pieces of cut glass.
