Lesson 1 of Charcoal Like Mad (by Kara Bullock) was to draw a portrait on cardboard (!) using the reference photo provided, and compressed charcoal (black and white), and charcoal pencils (black and white).

I only had corrugated cardboard available so I used that. Not crazy about the ridges, but hey, it was just play! This was fun — but I pressed too hard on the nose and busted a hole in the cardboard!
