These Save the Dates were printed on 100 lb. Pearl White Lettra Paper, two-sided, with a perforation to allow the recipient to interact with the attached thaumatrope. Included with the card in the envelope were two rubber bands that could be used to finalize the construction of the thaumatrope. In addition to the instructions on how to construct the toy, obvious relevant information regarding the wedding date was also included. The birds went on to serve as design elements in both the wedding invitations as well as day-of printed elements.
