Well this all started with an evening of drinking and discussing wedding plans with my FI. I really want an exciting entrance into the reception: imagine Jock Jams music, cool lighting and annoucing the WP as if they were Piston's players. Since he is in love with Michigan football he made a joke about using the "GO BLUE" banner as we enter the hall.

Well then I got to thinking that we could have all the guests sign the banner instead of a guestbook and the banner could have something unique to us (monogram, date). It would be a much better keepsake than a book that we would never look at again.
Although without the alcohol involved- he's rethinking the idea. My family would think its great, but my family also is known for bringing cow bells to weddings (seriously).
Has anyone done anything unique or different for the guestbook? Is this idea too wild/out-there?
