Happy140 demonstrates how to fold and wear a bandana. Folding a bandana and placing it securely onto your head for everyday use is easy using a few simple steps. The first step is to take the bandana and fold it into a triangle so that all the points touch each other and are even. Then, fold the top point down so the bandana forms a trapezoid shape. The next step is to fold the bandana in half lengthwise. Wrap the bandana around your forehead. Tie the ends of the bandana into a knot behind your head to secure the material into place.
