nice idea: bouquet toss: a bunch of single roses loosely tied together that will then separate when tossed - everyone gets a chance! I saw this at a wedding once and loved it! (maybe it's because I caught one of the flowers :) )
Have a ring warming ceremony to take the ring exchange one step further. Before the ceremony, pass the wedding rings around to the guest who imbue the rings with a silent prayer or blessing for the couple.
