Halloween Stamp Ideas

I'd like to carve some Halloween stamps. I'm thinking a bat like a tattoo I saw on a woman at Joann's yesterday. She had a bat on each collar bone. I could stamp a temporary tattoo on myself. That would be fun. And vampires of course are all the rage because of the Twilight movies. So maybe a fang stamp or something. I should make some Halloween (Samhain) cards for my pagan friends. I know I have some skull pirate stamps I've carved in the past. So where are they? I'm not the most organized person in the world. Out of sight out of mind. Which is why I don't like to put anything away. It may be years before I happen upon it again.
