How Can I ‘customize’ My Plastic Halloween Mask?
I recently got a Jason Voorhees style mask. Actually, its just a cheap, plastic hockey mask.
Okay, first of all, how can I make it look older? How ca I give it some "wear-n-tear"? Will tea-bag staining work on the plastic?
Also, I’d like to make it a bit scratched up. Could I acheive that with a knife?
And, if you have any other idea as to what I can do to make the mask better, please, don’t hesitate to tell me.
Thank you. 
sharp knife, throw it around on some concrete, scratch it against a wall ect, then rub dirt into the scratches and things.
throw it around on the concrete outside
