Wedding Thank You Card: "Love and Thanks" with the names of the bride and groom with the wedding date. By violaprints on Etsy. I saw this and fell in love with it because it's so different from your average wedding thank you card.
Alternative Wedding Invitations and Save the Dates: inflatable printed balloon. I think this would be a fun idea for a gender reveal party.give guests the choice of pink and blue balloons and they can write a name suggestion on it!
