Bake plastic on a piece of cardboard is suggested. It doesn't stick,
and the oven is low enough that the cardboard won't scorch or burn. As
with polymer clays, it is recommended that you buy a separate toaster
oven for baking - don't use your/school's regular oven. (Especially if
it is a convection oven...)
