Fold a square scarf diagonally until one end meets the other, making a large triangle.
Placing the scarf on top of your head, bring the middle of the longest side to the middle of the forehead so that the pointed end is towards the back of the head. Hold.
Bring the ends to the back and tie them in a single or double knot, whatever is more comfortable for you.
Adjust on forehead so that the scarf lies where you want it.
