So I completely forgot to enclose our RSVP cards in with our wedding invitations. I've already sealed the invites as well, so I'm thinking of taping the rsvp cards to the back of the invites but I'm super nervous that they'll fall off during transport. Please let me know if you've taped invites to the back of other invites and had it work? I'm super stressed now and we cant afford to budget in ordering new envelopes and stamps. it was expensive enough the first time around
