  • Patent number: 7231670
    Abstract: A versatile scarf includes an elongated rectangular neckband portion, a large half-fan shaped flap connected to one side of the neckband portion and a small half-fan shaped flap connected to another side of the neckband portion forming draping portions, and a loop coupled between the small flap and the neckband portion. Both sides of the scarf have the same configuration, therefore the scarf is completely reversible. The scarf can be securely tied by pulling the large flap through the loop between the neckband and the small flap, without using other fastening means. Depending on how far the large flap is pulled, through front or back loop, from top or bottom of the loop, re-looping or not, and depending on which side is showing and the position of the scarf, numerous stylish and distinctive appearances can be achieved. The dimensions of the scarf can be varied to suit different purposes.
