I first saw this here and thought I would try this for my Halloween party and was pleasantly surprised by the end result. I called it my Medusa Head.
I bought the cheapest mask I could find at a party store, a styrofoam head from a wig shop, and a heavy glass dinner plate at Walmart. I then hot glued down the head to the plate for stability, and then skewered some veggies and poked them in the head, and put the leftover veggies around the bottom of the plate.
It was a big hit.
