Step 1: Shape The Mask
It helps if you start on a face shaped foundation. In our case a 4 USD basic white paper mask from a hobby store.
Kind of hard to explain the way we made it. But the nose is basically a lump of paper porridge shaped into a pointy nose. Eyebrows are strings of paper porridge. Eyes made of a pingpong ball. teeth are just the "backside" of wavy cardboard.
I finished it of by applying (with my fingers) some white silicone to get a smoother finish, as the face otherwise will have an uneven surface.
Finish of with a few layers of even spray paint. Or any white colour. I did paint it black first, just to get an even colour when applying the white- not sure its neccessary.
