Distributing bookmarks

Okay, I think I have come up with a possible answer on how to distribute my bookmarks. There is a site called Book Crossing that I found a long time back and have been meaning to participate in. The basics of it is that when you have a book that you have read, instead of tossing it out, leave it somewhere for someone to find and read. I could leave the bookmarks I make with little polymer clay danglie dragons and stuff on them in my left books for people to find.
