Usually couples select them at least three to six months in advance to allow plenty of time for ordering, proofreading the text and addressing the invitations or hiring a calligrapher. Invitations should be mailed no later than four to six weeks before the wedding and up to eight weeks ahead for summer or holiday weddings, due to busy schedules. The items you order for your invitation set should include the invitation itself, as well as several enclosures. The invitation announces the wedding couple and their sponsors. Of course, it also lets your guests know the date, time and location of the ceremony.
Enclosures are the small cards included with the invitation.
They provide more detailed information than is available on the invitation itself. Pew cards are included in the invitation of guests of distinction, such as close family members and special friends. Invitations normally come with two envelopes, an inner and an outer. However, the more contemporary, square sizes usually only come with single outer envelopes. The outer envelope serves as the mailing vehicle, while the inner envelope protects the invitation.
