Sugar Skull Mail Art

Decorate an envie with sugar skulls. Add dancing skeletons, wild colors, folk art swirls, tattoo-ish roses...any medium... it's Sender's Choice. Send 'em naked. I'm most interested in the art on the mail, and I prefer empty, but if you like, you can put something inside for your partner. Write "empty" on the envie somewhere if it's empty (I don't like to disturb the art by opening when they're empty) and put a piece of cardboard (cut up cereal box, file folder...) in it to give it structure, and have fun!
