when the urge to draw strikes, anything can become a drawing material. at one of our favorite restaurants, i used hoisin sauce to doodle this portrait of christine (above). the waiter was so intrigued that he borrowed the plate to show off around the restaurant. when we returned a month or two later, the same waiter brought our utensils, water, plates, and ~ with a hopeful look ~ another squirt bottle of hoisin sauce. "i think it's your turn," i told my wife. she drew this portrait of me (below).
