My venue is all inclusive. Therefore, it includes a certificate to work with a local printer for STD's and invitations. However, I'm under the impression that the invitation only has the outer envelope. Inside will be the invitation and the RSVP card with an envelope for that (I believe, though I need to confirm this piece, unless the RSVP is more of a post card).
Is this OK etiquette-wise? I know that typically the inner envelope has the recipient's name(s) on it, so I wasn't sure.
