I meant to take some time to generate ideas for my Cafepress prints and cards shop that I've had for a year without developing. It needs filling with new illustrated products. Anyway, nothing was springing to mind, so my attention wandered.
There was a young woman sitting adjacent to me in the company of friends and I started drawing her but she was so animated and I was trying to be surreptitious, I had to turn it into something of a caricature. Maybe I should have suddenly told her to stop moving, for God's sake!
