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!
Print pictures on old book pages. Looks amazing. You could use a book that has special meaning with the picture or maybe sheet music. Perhaps you would like your wedding picture placed on your favorite song from your wedding. Would make a great gift too.
