A du rag is virtually the same thing as a bandana, which is a cloth that covers the head, and is popular to wear in a variety of settings to cover the hair and protect it from the sun. You can easily make a du rag out of your favorite shirt, and wear it to protect your hair from blowing wind while riding a motorcycle or to keep the scalp cool during days in the sun.
Lay out your shirt on a table, and cut out a square that is 22 inches by 22 inches. If the shirt is not that wide, cut the shirt up one side seam and lay flat to increase the width.
Take one corner of the square and fold it to the opposite corner to create a triangle.
Place the folded end of the triangle across the forehead, holding both of the triangle ends in each hand.
Tie the two ends in a knot behind the head. Tuck in the corner of the du rag that went over the scalp behind the knot to secure.
