oh wow! thats crazy!! i wish I was that organized! I have a couple of those big sketchbooks that are filled up, I'm just not sure where they are, so much moving around they get stuck in boxes and then lost lol XD
Originally they were just loose. Then I discovered clear files. I sift through them alot now cause of them. It's SO handy! I even have my unused comic pages in them. I love looking back at old art :3
