Part of my complicated relationship with sketchbooks is that I'm far more productive with the sketchbooks I hate (because I just want to fill them up and get it over with) and then I'm hesitant to use the ones I like best (because what if I mess up a page and "ruin" the fancy sketchbook?). Also, I can't seem to behave and limit myself to the correct medium for each sketchbook so I'll end up doing watercolor in a sketchbook absolutely *not* meant for watercolor so there will be these random wrinkly pages in the middle. And I'm always like, "Oops, I must remember this sketchbook wasn't meant for that" and then a dozen pages later I go and do it again. ("I won't use as much water this time. It'll be fine." It's never fine.)
