Years ago, when I was expecting Ben, I worked at the University of Utah. Mail came in from all over the world with the coolest stamps. One of the professors, Yukio, the nicest little old man from Japan, would always leave little bundles of these stamps on my desk after he'd gone through his mail. I guess he noticed me always looking at them when I was sorting the mail.
Even after I left, Yukio would mail me envelopes stuffed with foreign stamps and a little note to say hello. It's been a few years since I've heard from him, but I still have all the stamps.
I've been wanting to use them for something creative for a long time, and finally Ben helped me make this stamp collage to hang up in his bedroom. We got the idea here, if you want to check it out. And you don't have to be a stamp collector to do this, I've found lots on ebay for practically nothing.
