Instead of a boring old guest book, I considered a photo book for guests to sign. Then I decided I would prefer something we could see everyday. So I brainstormed items that could be hung on the wall. Once I saw samples of certificate-style guest books, I was sold. So I created a file (a derivative of the invitation) and made it like the Declaration of Independence a la a marriage license. In hindsight we should have made a request for folks to sign one name per line so we didn't have so many spaces leftover but it's such a wonderful keepsake to have!
