How have you decorated a mask?

If it's a foam rubber prosthetic mask, I used grease paint from a site called boneyardfx.com

I think they have tutorials too.

(And if you're interested, there's lots of info on decorating masks including making your own masks as a part of that, on this page at my site:

Decorate it with feathers, beads, rhinestones, glitter and paint. You can find these supplies at your local craft or hobby store. Good luck!

Yeah, I pasted cardboard and newspaper over it, then painted it red, black....and put glitter on it

the same as the dress up your face
