You've finalized the details and the invites have been mailed – now for remembering it all. The Wedding Guest book from @artifactuprsng is equal parts conversation-starter and memory-keeper. This book is best spent in good company – set it on display with a pen for your guests to sign their well-wishes on each page.
Photo Guest Book. We did this for my aunt and uncle's big anniversary party, but with a photo printer instead of a Polaroid. All the pages were black and the guests used glitter pens to write with. It was classy and a good keepsake. Definitely want something similar for my wedding.
