I really like this sketch, but it was nearly a right old mess.
Earlier that day, I had been showing my sketchbook to some small children at a school in Leeds and did a quick demonstration of the watercolour pencils and waterbrush I use (kids always love it - it's magic paint!). I must have not quite screwed the top back on my brush properly: when I started to use it later on the train home, I suddenly has a small lake slopping about on my sketch!
I didn't want to blot it off, as that would definitely have ruined the drawing, so I blew on it, fanned it and tipped it back and forth, trying not to spill any of the inky water in my lap. It took the rest of the journey home to dry. I still had to walk through Sheffield Station wafting my open sketchbook back and forth in the air (what an attention seeker...).
I was out on trains 2 days last week. They were mostly nicely crowded, so plenty of victims to choose from and most of them up nice and close. Perfect. As you can see from the way everyone is wrapped up, it's been pretty chilly over here!
