Cover artificial pomegranates with copper leaf for festive decor that will never spoil. Just insert wooden skewers into artificial pomegranates. Coat each with adhesive size. Stand skewers upright in a piece of Styrofoam; let pomegranates dry until tacky (about 7 minutes). Following manufacturer's instructions, apply sheets of copper leaf until pomegranate is covered (approximately 2 sheets). Repeat with each pomegranate. Display on a tray, in a bowl, or on a cake stand.
