The task today, at the WA, was to draw each other, a 20 minute sitting each. Penny asked me to give a few pointers, as I do portraits, but the the others generally don't. I decided to demonstrate, but did my usual thing of concentrating on the job in hand and forgetting to talk!
I chose a carbon pencil because it looked like mostly everyone else had pencils. I prefer charcoal, though, as I find it easier to work and far quicker to get a good result.
