What are double envelopes?
A more traditional, and more formal, invitation will include double envelopes. The outer envelope will include the guest’s full name and address, and it will be sealed. The inner envelope will include only the guest’s title and last name (such as Mr. Smith) and will be left unsealed, as it is not gummed. If you are ordering double envelopes and wish to include an envelope liner, the inner envelope will be the lined envelope.
