Yesterday I saw a little boy walking the aisles of the co-op sporting a pair of faux vampire teeth. I've never understood their appeal, as, if I remember correctly, they kinda hurt your mouth. Better use of them would be to make Martha's Fang Pumpkins (aka Drac-o'-Lanterns). Besides the fangs, we'll need some small pumpkins (preferably white, but I'd think we could white-wash some of the orange variety), a tiny saw, small red map tacks and a mouth template, which Martha provides. For rest of the details, including a video, go to this page on Martha.
Martha gives us all the details as well as a mouth template and even a video. Darling.
