Many of the patterns that incorporate hearts were inspired by Mexican Folk Art and sacred hearts. The Charger pattern has a heart in the center with lighting bolt style decorations radiating out. The Luz pattern works better on a strip of leather, such as a belt or a collar, and is composed of little flaming hearts and barbed wire. The Milagro pattern was inspired by the small tin milagros (or "miracles") and has one large heart with flames and a decorative border.
