You've got to find a way to get some diversity. I might take some of the shaping of the face plate off, to be a generic round or egg like shape. But I thought just a simple black background with a painted front will do.
Playing with my cutting machine and traced out some images I think this might solve my Zombie problem!
Not a fan of Spiderman or anything, but it will make a Bad (you know what) stencil for painting!
If anyone has any ideas for stencils I'm very interested!
