Undulating black and white stripes flow across the composition in a rhythmic, wavelike pattern that seems to shift and ripple before the eye. The linework creates an optical effect of continuous movement, where parallel curves interweave to suggest depth and motion on a flat 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.
