For the last couple of years I've been collecting hand written notes I've found, in general, on the floor. It started when I sat at the back of a bus and two schoolgirls had written a conversation while in a science class about how disgusting boys are (i may submit this someday). I was working on a project about identity at the time, and realised that little handwritten notes can tell you so much about a person - even if you've never seen the person. Post-it notes, perhaps, are not such a good exmaple of this, but I have some other peices to submit - and you'll see what I mean. I've never really been sure how to present them, though - I'd certainly never be able to scan them all. These are just the post it notes. There are hundreds and hundreds more.
Oh and if anyone knows a better category to put this under, let me know. Collections?
