"Treat People with Kindness" floats in bold, rounded letters across a mesmerizing checkerboard ground of coral, pink, and orange that warps and undulates with a groovy, op-art rhythm. The wavy, tessellating pattern creates a sense of movement and warmth, while the clean white lettering with subtle outlines anchors the uplifting message at the center of the composition. 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.
