Adding an outer envelope to your wedding invitation adds a traditional and elegant flair.
Traditionally, an outer envelope is used for the postal address and an inner envelope for hand writing the names of whom is invited. For example the outer envelope may be addressed to your friend Jane Doe. Jane is not married and you want her to know it is okay to bring a guest. On the inner envelope, you would handwrite Jane and Guest. Another example would be addressing the outer envelope to your Uncle Bob and Aunt Rebecca Johnson. Because you want them to know their children are also invited to the wedding, you would handwrite Bob, Rebecca, Susan, Anna, and Ronald on the inner envelope.
