We are having my fiance's two nephews walk in our wedding, and we didn't really want to call them "ring bearers" because they aren't going to be carrying our rings & we really don't think we want them to carry pillows. One of the boys is 6 years old and the other is 8 years old. They are also going to be walking down the aisle with my two nieces. Any suggestions on what they can carry &/or do while walking down the aisle?
