Four horizontal wavy lines rendered in soft blue brushstrokes ripple across a pale gray ground, evoking the gentle undulation of water or heat shimmer. The loose, organic quality of each line creates a rhythmic, meditative composition that balances simplicity with movement. 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.
