Write you names and wedding date on a wood heart and frame it. Have your guests sign smaller hearts and drop them via a small slot on the top. What a cute and unique guest book idea that you can display after your wedding.
I love this idea instead of a pillow. And rather than being a waste of money or a one-use item, you can set this on the dresser and use it as a ring holder for the times you need to remove your wedding rings!
