A grid of interlocking semicircles and quarter-circles in teal compose a rhythmic, tessellating pattern that shifts between positive and negative space. The geometric forms create an optical play of depth and movement across a light cream ground, evoking the systematic abstraction of mid-century modernist artwork. 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.
