Bright yellow triangles tessellate across a white ground in an orderly, repeating grid pattern that suggests both mathematical precision and playful rhythm. The composition evokes the optimism and clean lines of mid-century modern artwork, with each triangle pointing in alternating directions to create a dynamic, interlocking surface. 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.
