Tell us about yourself!
I did this originally making a mask and looking through the mouth but it was not great, your idea was brilliant, I used a skater helmet from Amazon, lifted the mask up and used the mesh side from a bra to look through. I also added a mouth which I used card and a wire coat hanger to hold the shape, the teeth were velcro so they also kept it in place.
Thanks so much for this tutorial, it really helped when making mine. not as good as yours, but version 2.0 will be better. I went for the 'awaiting post-production' effect on the arm :-)
