The groom and the best man praying right before he walks to the alter. Nothing would melt my heart more than to get my wedding pictures back and see this among them. Maybe a picture of the whole grooms party laying hands on the groom?
Love the Best Man Sandwich idea. Your fiancé's best friend adores you for numerous reasons and you've made his pal the luckiest guy in the entire world by agreeing to marry him. So come here for a hug, already.
