Rows of hand-drawn indigo blue vertical lines create a rhythmic, wave-like pattern across a white ground, with subtle variations in line weight and spacing that suggest organic movement rather than mechanical precision. The composition has a meditative, textile-like quality, evoking the structure of woven fabric or rainfall, rendered in cool tones that shift between deep navy and lighter blue. 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.
