I have a bunch of boxes jammed full of printouts, sketches, and random paper stacked up in the closet. Most of it are boring text and kerning proofs. Some of it is actually pretty interesting though. And the boring stuff adds up to make an interesting record. A few years ago I thoughtlessly tossed all of my early Alright Sans process books and deeply regret it. Since then I've been hoarding everything but it's turning into a lot of stuff.
I'm just curious what everyone else does with their stuff. What do you trash? What do you keep? Why?
