A geometric rainbow curves across a muted, earthy palette of sage green, mustard yellow, terracotta, mauve, and cream. The concentric arcs create a sense of calm movement and warmth, rendered in flat, layered bands that suggest both retro minimalism and natural phenomena. 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.
