Here's an amazing idea for a summer wedding:
Hand-drawn fans with little portraits of the key players as a guide!
No more whispers of "WHO'S THE CHUBBY ONE WITH THE CUTE HAIRCUT?" or "ISN'T THAT THE ONE THAT SHE DATED FOR THREE YEARS IN COLLEGE?" They may be thinking it, but at least they won't have to ask their seatmates during the ceremony! :)
