Here's my idea: have a professional photographer friend take pictures of each couple/family/friend at our reception during the cocktail hour and send each person the picture with their thank you card. My friend is already covering part of the wedding (I only could afford a professional wedding photographer for three hours, so she's covering what they won't be around for) and I thought each couple would like to have a picture of themselves all dressed up. I wanted to do a photobooth but my venue doesn't allow it, so I thought this would be nice. Any thoughts?
