These are some of my favorites that I have found.
This is a great idea if you want to include pictures, or if you have a ton of engagement pictures that you love and want to show off. Snapfish is a great place to create one of these books. Simply leave somewhere at your reception and have everyone sign.
Lastly, I love this idea where each guest gets a piece of paper and their own envelope to put their note card in. How fun would it be to go through the book year after year.
One thing to remember it is better to put a guest book out at your reception rather than at the ceremony when guests are arriving. By doing this it gives everyone time to write something and have fun with it, instead of being rushed. Plus it gives everyone something to do during cocktail hour or in-between dinner and dancing.
What did you do at your wedding for a guest book? Something traditional? Or quirky? I really love the Polaroid option! So fun for years to come!
