Thin vertical stripes in red, orange, yellow, green, cyan, and blue dance across a white ground in a rhythmic, gently undulating pattern. The lines waver and shift with organic movement, creating a sense of playful energy while maintaining an ordered, repetitive structure. 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.
