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!
Boston, Massachusetts Wedding by Datura - A Modern Garden
i used this design for a class and it turned out amazingly! instead of gold, I used a textured indigo cardstock, and i put a light pink ribbon with one little jewel on the cover and a picture on the back. it was super classy.
