Your invitation lays face up as the bottom piece. Place tissue (if included in your engraved order) over the invitation. Slip your reply card under its envelope flap (be sure to affix first class postage to the front of your reply envelope). It will be placed address side down so the reply card text faces up. Layer the other inserts (reception card, map or directions, and reply set) on top of the invitation with the largest item at the bottom and smallest item on top. Insert all pieces into inner envelope with the top of the invitation to the left side. Turn the inner envelope over to expose your guests' names and insert into outer envelope. Voila! You are ready to stamp, seal and send! Be sure to take 1 fully assembled invitation to the post office & have it weighed so that you can be sure to use the correct postage.
