Non-toxic doesn't mean squat.

Cupcakes!, originally uploaded by feathermar.

So, I love to bake cupcakes because I love to eat cupcakes. On top of that, I have never ever used fondant before, and I'm pretty sure I pronounce it wrong when I say it aloud. But it sure is fun to make into polka dots. It's like edible modeling clay.
But "edible" doesn't mean you should eat a lot of it. Because you might get sick. Just like "non-toxic" markers shouldn't be licked. Even though you can lick 'em. You just shouldn't . It's not a good idea
