Everyone should take part in The Ephemera project. My Friend Tate is the ringleader and you can find her at www.theephemera.com Long story short just do this:
"send in your "ephemera". i'm keeping it simple and broad. stick to the definition if you wish or obscure the crap out of it. whatever. as long as it explains what ephemera means to you. examples can range from an old ticket stub to a q-tip, an instructional pamphlet to rubber bands. it could even be a letter describing your thoughts and ideas on ephemera."
