You can also consider the quality of the paper that you plan to use for your invitations. If the paper is high-quality and thicker, then a second envelope may not be necessary. And, it could add to the postage cost as well.
If you don’t know the invitee that well, it’s still okay to lean toward the more formal and include their full name on the inner envelope.
For example, in the addresses, you should put “Lane” instead of “Ln. ” Try to include your invitees’ middle names. However, if you don’t have it, go with the initial or just use the first and last name.
For the inner envelope, go ahead and shorten your greeting to, “John and Emily” or “John and Emily Perkins. ”
For example, the outer envelope might look like, “Mr. Mike Smith and Mrs. Samantha Wise. ”
For example, the first line on the outer envelope might read, “Ms. Amanda Jones. ” The second line might read, “Mr. Michael Adams. ”
For example, the outer envelope might state, “Mrs. Nancy Stevens,” or, with the husband’s full name, “Mrs. Charles Stevens. ” For the inner envelope, shorten it to, “Mrs. Stevens,” or “Nancy. ”
For example, the outer envelope will state, “Doctor Anne and Peter Thompson. ” The inner envelope can show, “Doctors Thompson. ”
For example, the second line of the inner envelope might look like, “Michael, Miss Rebecca, and Steven. ”
Mention that children are not invited on your wedding website. Include your reason if you think it will help parents’ understand.
