"Anything Goes" Bookmarks

Note: I'm posting this in January because I just thought of what I think will be a cool idea-but it's not coming due until June!

Well, the name about says it. Two bookmarks, to each of two partners (4 total), and whatever you send has to be book-usable. So remember, it can't be thick enough to bend a binding or sharp enought to rip a page. The libraries frown on that. So do book-owners, right? Welcome to international participants and to newbies. No skunks, please! A special gift to the first three to sign up! Get your imaginations ready.
