There are some extra stationery things that are required when ordering invitations. RSVP cards are required if couples are having a sit down dinner. Couples need to know the guest count to figure out how much food to order. It is no longer tradition to pay for postage for guests to send the RSVP card back to the couple. Send invitations early to give guests plenty of notice about the wedding. They should be sent out at least two months before the wedding and no more than four months before. Make the RSVP date between four and six weeks before the wedding. This helps you know exactly how many guests will show up.
Choose invitations that actually look inviting. Thick, high quality paper with bright colors or a unique design that makes the envelope stand out from other mail that may arrive on the same day. Your invitations should excite interest even before they are opened, and if you have chosen your design well, they should evoke reminders of the happy couple as well!
