Anyone using a wax seal on their invites? My FH is a big history buff so he wanted to have a vintage feel to the invites so I thought maybe a wax seal would be cute. Does this mean I need to have an inner envelope though? My invites will be flat 5x7 cards, plus an RSVP card and RSVP envelope bound together with a piece of tulle. I was thinking it might work to wax seal the tulle to the back of the invite card. Thoughts? Anyone else doing wax seals? How will you use them?
