We are making our invitations completely by hand so i have been making a piece at a time and of course as I go adding things... Well we decided to add a ribbon with monogram block around the pocket folder to seal it, but that was after we had already designed and printed all the RSVP cards and about half of the envelopes... Since we are not planning on using a second envelope as the pocket folder is mainly an envelope. Would it be fine to have a special insert to inform guests that they are able to bring family or a plus one (depending on the invite)? And How would we want to word it? Reprinting the envelopes and/rsvp would cost too much plus all the time as most of the people either have a family or plus one.
