I do it a lot when I’m on the phone or when I’m listening to a presentation or anything where I have a piece of paper in front of me really. I think doodles are super fascinating. I never mean to doodle and sometimes I only notice it after I’m already done. They’re art created straight by the subcoscious in a way.
Mine are often quite large and have little whitespace left. Big, intertwining blotches with soft curves and neatly filled in lines. I’ll see if I can find one to share in the comments.
Mine start as trying to draw people or objects but end up as a dense bunch of abstract shapes with a few patterns and vague faces hidden inside if no one stops me after a while
