A grid of interlocking geometric tiles fills the composition with a tessellating pattern of diagonal lines and angular shapes in black ink on a cream ground. The repetitive linear hatching creates a hypnotic optical effect, with each tile shifting direction to build a rhythmic, maze-like whole that rewards close looking. 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.
