I glued three pieces of toilet paper to my face using spirit gum and then ripped them starting at where my mouth ended. The glue kind of made the toilet paper stiff so it was easy to paint with face makeup. I painted side of my cheek where I had ripped the toilet paper off black and then painted teeth on with white face makeup.
I also used a lot of fake blood and basically poured it into the fake gash to make it look like it was using out natural. I also glued toilet paper to my other cheek to make a smaller gash and proceeded to paint the rest of my face a greenish zombie colour. Every where I went people would ask me where I purchased the face piece and were shocked to find out that I had made it.
