Create a card for the friend with a strict no-gifts policy. It had to be celebratory, unique, and feel more like a gift than a card, but be easily mailed, in a standard 4" x 9.5" business envelope.
Clever typography takes the form of graduated "pages" in festive color palettes. Flippable pages invite handling, and the sender can write anywhere on the bookcard, hiding short messages throughout, or a longer message on the solid last page.
Cardstock, cotton string.
