it counts as recycling, doesn't it? i've been making these since i was a kid. every so often, when i'm in the grocery store, i pick up a couple of #6 plastic containers from the deli department and take them home. they shrink into hard charms when you bake them.
a necklace i made in memory of the daftest punk i ever knew who lost his life in the river last summer (r.i.p cheese ♥). since i'd be the one wearing it, i made some matching earings :)
i've heard about the danger of the fumes, but i keep it well ventilated and never leave the plastic in long enough to burn or smoke.
