Nested U-shaped lines in rust orange and black create a rhythmic grid of interlocking arches that repeat across the composition, evoking the geometric optimism of midcentury artwork. The pattern generates a hypnotic visual rhythm through precise parallel lines that alternate direction, building a sense of forward movement and structured harmony. 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.
