Want a guest book you'll actually look at again? This is a fun addition for your first coffee table as newlyweds. Create a photo book of your engagement pictures for your guests to enjoy, flip through and sign at your wedding. Mixbook offers a great selection and various designs for your personalized engagement photo book.
Or maybe you want to just throw the book out the window with this fabulous idea. Have your wedding guests sign several full bottles of your favorite wine, so when you go to open the bottle and drink, you'll have those little messages from the guests and remember your big day. You can then put the empty, signed wine bottles on display somewhere in your home.
Batter up! This might not be idyllic for all your guests to sign, but if you and the love of your life are baseball fans, a favorite team/player jersey signed by your bridal party and framed might just be the ticket.
