Overlapping sea urchins in coral, blue, yellow, mint, and pink float across a warm beige ground, their spiny surfaces rendered in delicate radiating lines that suggest both scientific precision and playful abstraction. The composition balances organic forms with geometric restraint, creating a calm, meditative rhythm that feels both modern and timeless. 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.
