A cheerful green caterpillar composed entirely of musical notes inches across a bright yellow ground, its rounded head topped with two curved antennae. The playful illustration combines the organic form of the creature with the flowing rhythm of music, creating a whimsical composition that merges nature and melody. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
