In addition to the invitation card that informs your guest of the specific ceremony details, you will find enclosed with it reception cards, response cards and direction cards. A reception card can be avoided if your ceremony and reception will take place in the same location.
Most couples choose to include directions with their invitations to help ensure their guests arrive promptly. Often you can combine a map, written directions and accommodation information all on one card. Etiquette directs you to make the whole invitation very simple but we recommend that you avoid a separate mailing. This will save trees, reduce waste and cut down on costs!
You will need a response card if you are having a catered event. Your caterer will need to have a final guest count within two weeks of your event. You can save trees/waste/money if you use the more casual postcard style response.
Traditionally, invitations were sent in two envelopes so that the servant of the house could open the outer "soiled" envelope and present the master of the house with the pristine inner envelope. Earth-friendly/budget-friendly single envelopes are our favorite! Single envelopes do present a dilemma. Read more about how to deal with that issue here.
