A 3x4 grid of interlocking semicircles and quarter-circles creates a rhythmic geometric composition in shades of teal, forest green, and chartreuse. The overlapping curved forms generate an optical pattern that shifts between depth and flatness, evoking the balanced abstraction of 1950s 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.
