Moglea's Rainbow Heart card is hand-painted on thick pulpboard in the studio's Des Moines, Iowa workshop, then foil-stamped in copper on one of their antique presses. Each card is cut from a larger painted sheet, so the rainbow lands a little differently every time.
The front reads "I love you so much." A flat card, 5.5 × 4.25 inches, with an envelope — for the person who'll keep it on the fridge.
