Repeating semicircular forms radiate outward in dense, symmetrical rows, their surfaces filled with fine linear hatching that creates depth and movement across the composition. The pattern alternates between dark and light tones, producing a mesmerizing optical effect that suggests both natural phenomena and geometric precision. 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.
