I decided to sketch Ms Kahlo the other night. Here she is! I just used a pencil and my watercolour pencils to start with. I'd given the pencils a quick brush of water to blend them, and then decided to give her skin a wash of red wine with the brush. It looked lovely and blushy pink at first when it went on, and then turned a bit purple-grey when it dried. Kids - don't paint with wine.
