Bright yellow circles and triangles interlace across a white ground in a precise, repeating grid that suggests both mathematical order and organic rhythm. The white negative space carved within each geometric unit creates a shimmering optical effect, giving the flat pattern an illusion of depth and movement. 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.
