Starting to think about your wedding stationery but not sure what items you need? Invitations, envelopes, but what else should be in your stationery checklist? If you have any extra details beyond the main invite content, we suggest adding information cards to your stationery suite. Information cards, or accessory cards are included with your wedding invitation to add any extra details that won’t fit on the main invitation. Accessory cards can include an RSVP and gift/wishing well card, as well as a map/directions card, accommodation card, a reception insert, weekend itinerary, and website card.
