Pew cards are an optional enclosure in a wedding invitation that let a select group of family members and friends know that they are to be seated in a special section. If you want a guest to have a specific seat, you can include a seat number or location on the card. Most often, you would simply mark off a series of rows in the front with ribbon or a sign. At a smaller ceremony this is a less necessary detail, but if you have a large guest list, it might be nice to reassure your relatives that seats are reserved for them. Make sure to communicate with your ushers about where you want guests with pew cards to be seated.
