I would just like to show off my new fibreglass mask that I spent the last few weeks making. If you want to make something similar then I'd refer you to DecapitatingJim's 'Ible, where the full process is detailed: https://www.instructables.com/id/Making-a-mask-out-...
Follow the instructions well, I tried to cut corners and that just added stress ;)
I have't done straps for it yet but I'd like to get leather or thick elastic for em.
The mesh for the eyes is aluminium mesh from Halfords spray painted black
Step 1: It Glows!!
I got some glow in the dark powder from solarcolourdust.com and mixed it with epoxy resin (which is the luminous orangey/red stuff around the eyes and mouth.
The photos don't do justice to the glow, it is really bright!
