Undulating waves of saturated color bend and flow across a grid of small squares, creating the optical illusion of fabric folding in space. Stripes of red, orange, yellow, blue, purple, and gray ripple through the composition, anchored by a dark grid that emphasizes the warped, three-dimensional effect. 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.
