Geometric semicircles and circles in olive green, coral orange, dusty pink, and chartreuse yellow stack and interlock across a cream ground in a rhythmic grid. The composition balances bold color blocking with negative space, creating a sense of playful order that feels both retro and timeless. 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.
