A grid of interlocking geometric rectangles alternates between turquoise and lime yellow, each square anchored by a centered circle that creates a rhythmic, repeating pattern. The bold color contrast and clean linear construction evoke the optimism and graphic precision of mid-century modern artwork, with a flat, graphic quality that feels both structured and playful. 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.
