DIY Medusa headpiece. Instructions from poster: I bought cheap plastic snakes at the $1 store (a few dozen in a pack), wire, a double banded headband, and a can of gold spray paint. I wired the snakes into a great little tiara and then sprayed the whole thing gold and I really loved how it turned out.
Spooky Black Bean Hummus Recipe from FatFree Vegan Kitchen. To create spider web & spider design: "Using a pastry bag and either soy yogurt or thinned tahini, pipe on the design. Place a plastic spider into the web, or make one yourself from black olives."
