Is anyone doing anything other that just a guest book at their wedding? I've seen some couples have a photo matte that everyone signs and they can put a wedding photo in it.
One idea I'm carrying over from the bridal shower is a jar for "Date Night Ideas". People write down an idea for a date night for us. I didn't get too many at the bridal shower so I thought I'd set it out by the entrance so more people can give ideas.
