Interlocking triangles in red, orange, yellow, blue, and pink form a rhythmic tessellation across a white ground, their outlines crisp and geometric. The pattern repeats with mechanical precision, creating a joyful, meditative composition that feels both structured and playful. 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.
