Interlocking semicircles in coral, pink, orange, and cream form a rhythmic geometric grid that recalls the optical experiments of 1960s modernism. The repeating pattern creates a hypnotic, almost three-dimensional effect through careful color blocking and symmetrical 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.
