US Backcard Story
Mainsail stood on the dock admiring her new sailboat. "It needs more color," she thought, frowning at the white sails. She flew into the air and took some magical powder from the rainbow. She tossed the glittering powder on the sails, and bright designs magically appeared on the sails! Some of the rainbow powder drifted onto Mainsail's hair, streaking it with color when the sun touched her tresses! Admiring her new hairdo, she hopped in her boat and headed out to sea!
