This year I'm going to be Poison Ivy for Halloween. I originally was going to be a splicer from Bioshock (Click here if you dont know what that is) so I had a mask already and I didnt want it to go to waste so I made it work!
This mask is made from plaster and I just put some acrylic paint over it and hot glued leaves... It was very, very easy. If anyone is interested in making their own mask watch the following vid.
