Face paint

Disguise Stix from eBay. I like the popsicle format because you don't get hands dirty to apply it;you just hold it under running warm water and apply. You put it in ziplock and take with you to show and offer to paint everyone else in the audience :)

It washes off with soap, lots of soap. The paint itself is actually soap based. Makeup removal napkins help a lot. I have Royal Red and Midnight Black for Turisas purposes.

See avatar to get an idea of what colours actually look like.
