I made this today, very easy and fun to make. I used the easy eyes tutorial on haunters hangout and their easy eyes pupil print out sheet. I didn't drill it or attach a wire as stated in their tutorial I just stuck on the pupil with a glue stick used a fine brush to brush on some tiny veins with some red acrylic paint I had and then painted over the pupils with some clear nail varnish.

I used two cheap Hessian sacks I got from ebay, one inside the over as you can see through them fairly easily and filled the inside with some stuffing from an old sofa cushion. Then I tied the outer bag at the top cut a small hole in the outer bag and hot glued the eyeballs into place, then sprayed on some fake blood I had and smeared it a little with my fingertips.

I've seen similar props sold online so I thought as it was a simple Idea I'd have a go at making my own. I'm now saving all my old deodorant balls lol.
