Bold black and cream wavy lines ripple across the composition in hypnotic, undulating patterns that seem to shift and flow like water or fabric in motion. The rhythmic parallel strokes create an optical illusion at the center where they converge, producing a mesmerizing three-dimensional effect that draws the eye inward. 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.
