Making these contemporary layered or wrapped cards is inexpensive and fun
Address the envelopes before stuffing them. Then insert your invitation into the envelope with the text facing the flap side.
To create a reply card, buy 50 postcard-size flat cards in a coordinating color (about $7 for 50). Print your RSVP information on one side and your return address on the other.
Slip your reply card and any additional wedding information (such as a map and directions) behind the invitation.
Take completed invites to your post office and have them weighed to ensure correct postage. Visit www.usps.gov to look up zip codes and rates.
