When I fly aerobatics I like to have the least amount of cockpit clutter I can achieve. So the kneeboard, checklists, charts, license and everything is all tucked away in a safe but accessible place before take-off. The only thing I need to keep handy is my sequence of aerobatics figures. So I just put an elastic rubber band around my leg and tug that piece of paper (A6 size) underneath it. Maybe that'll work for you too?
