We are ordering escort cards to match our invitations, because I am crazy and like matching things. I want to order 1 per couple to save a little bit of $. This works fine for Mr. & Mrs. Smith, but what about people whose partner has a different last name? Should I do separate cards in that case? Or put them both on the same card with the alphabetically first name, first? Or do I need to suck it up and buy 1 card per person?
