Vertical ribbons of saturated color form interlocking hourglass and wave patterns that ripple across a cream ground, creating an illusion of rhythmic movement through concentric curves. The palette spans teal, coral, pink, yellow, and gold in bold, flat strokes that evoke 1950s modernism with geometric precision and joyful energy. 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.
