I ran across this wedding a few months ago on Once Wed and am completely in love with this idea! At the ceremony, each guest received a personalized tambourine! How cute is that?! They were made in a multitude of colors, stamped with the couple's initials and the wedding date. Instead of having someone sing during the ceremony, the whole crowd joined in chorus and played their tambourines! What a unique favor for the guests to take home and I'm also imagining quite a celebration of sounds at the announcement of man and wife! So perfect for a casual outdoor wedding!
