During the last 29 Faces challenge (September 2014) I painted several girls on backgrounds that I had made from coffee stains. Often I painted directly from my coffee cup - this time I decided to use the coffee to paint a girl's hair. I would paint some and then dry it with a heat tool and then add a bit more.
Ended up with a kind of tortoise shell look - cool for an ATC - not so much if it were real life.
Check out all the fun with 29 Faces!
