Caffeinated Portraits:
Using Coffee As Paint from The Organic Painter
This is a great project for those of you who like a strong cup of coffee in the morning. Begin by brewing some of your favorite coffee. This demo uses a strong cup of espresso, which gives the best color painting, as espresso usually contains the oils of the coffee bean and has the richest color. Adding to this are a pot of filter coffee and some ground coffee, or you can use granulated or freeze-dried coffee as a substitute. Learn more in The Organic Painter by Carne Griffiths
