Nested rectangular frames in coral pink, deep teal, and orange radiate outward in a symmetrical grid, each square containing concentric stripes of complementary hues. The pattern repeats across five rows with mathematical precision, creating a rhythmic, hypnotic composition 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.
