We're doing a guestbook that is a drawing of a redwood tree that will eventually hang on our wall. the idea is that guests will sign their names within the tree....on the branches, in the tree trunk, etc. And that the background (aka white space) won't have any signatures on it, but how do you ask guests to only sign on the tree and make it sound nice? (I know there's a good chance people will sign on the white background, but hoping by some miracle the guests won't).
Thanks!
