A boarding pass invitation with a tear-off response card is a great option if you want something custom and unique, but also simple and budget-friendly. The tear-off rsvp needs only a post-card rate stamp (28¢ postage). These invitations are as great for weddings as they are for bar & bat mitzvahs, sweet sixteen parties, or rehearsal dinner invitations (especially if your wedding invitations were of the passport variety)!

Marine wanted to incorporate a Marlin into her stamp for her Florida wedding, and picked a great blue envelope that has a VERY subtle marbled effect.
