The one problem with having a studio is that when I'm at home, and suddenly remember I want to draw a birthday card, I don't have any of my good art supplies lying around; I have to grab whatever I can find. So occasionally friends get hideous stuff cobbled together from the cardboard in tights packets or painted with tea.

They're good fun. Here's a picture of Stuart reading The Guardian:
