The Pikorua design on each tag (also featured on their wedding invitation and the wedding program) is a Maori symbol that "encompasses the solidifying of two people's love for one another."
Below is a close-up of the "tent."
The wedding, of course, was lovely! Since the groom is Scottish, he wore a kilt (as did the best man, his brother). A bag piper walked down the aisle just before the bride and then stopped off to the side to play the music for the bride to come down the aisle.
My contribution to the wedding was done. Everyone knew where to sit -- a minor yet important role, eh?
