Place a bandana wrong side up on a table or other flat surface. If the bandana is small, fold into a triangle so that the wrong side faces inward. Arrange the triangle so that the folded edge is closest to you.
Fold the bandana about 1 1/2 to 2 inches from the closest side of the square. If using a bandana folded into a triangle, start folding the same distance from the folded edge. Keep folding until you've folded the entire bandana to the desired width of 1 1/2 to 2 inches.
Take an end of the folded bandana into each hand, and wrap it around the base of the head and behind the ears. Gather the loose ends of the bandana at the top of the head, and tie tightly once to fold a bandana like Tupac. To make the style more secure, knot the ends a second time.
