My FI and I don't want to have a bouqet/garter toss, but instead want all the married couples to come out to the dance floor for a song and have the guests stay on the floor until they are dismissed depending on how long they have been married. Then the last couple standing will be the longest married couple at the wedding. I then want to present them with a gift (from newest married to oldest married). I like how this celebrates the longevity of marriage. My question is what would be a good gift? I was thinking about a nice wall hanging about love, but I don't know... Any specific suggestions?
