I'm trying to figure out what all to include in my invitations. In a perfect world, I would have a pocketfold, the invitation, 3 insert cards, and the RSVP envelope. However, I have a bad feeling that would put the invites over an ounce and I can't afford that much postage. If you did something like that, how much was postage/envelope? If you kept it under an ounce, what all was included?
