I call them shrinky dinks but they’re not really. They’re made by putting small plastic beads into a pre-formed metal outline. Then they’re baked in the oven so the beads melt into something that looks like glass. These were actually really tedious to make. Getting the beads piled up to just the right height so that the area gets filled in but doesn’t overflow is tricky and it’s not uncommon to open up the oven and find that one red bead rolled off it’s pile into the middle of a white section.

The ones that came out nicely I do like, but it was a little hit or miss. What was especially hard was leaving the white beads in long enough to melt completely but not so long that they scorched and started to turn yellow. I definitely have some yellow spots on my snowman.
