New sketchbook page

Sketchbook page. I love the undulating middle of this. I keep doing sketchbook collages with a blank space down the middle. It’s nothing I’d ever do normally, but play is the operative word in my sketchbook work and so things tend to just appear. I wonder if at some stage it will start appearing in my other work? With hindsight I have learned that my sketchbook tends to be a year or two ahead.
