A PA Dutch hex sign design, the most basic motif. The rosette symbolize luck; a scalloped border symbolizes a trouble-free life. The rosette's color (red) signifies strength; the green of the border signifies life. This design is considered a potent safeguard against harm and portends good luck in life.
