Planners are a waste for me because I never use them. Sometimes I'll write in birthdays and maybe one or two dates, but then they only take up space.
They make great scratch pads for quick notes, doodles, practice sketches, or playing with ideas!
These were all done in very poor lighting using the wrong eye glasses. In fact, I could barely see what I was doing. There are more scans coming, and I plan to keep scribbling under the same conditions in my unused planners.
