Here it is, step by step:
You will need a regular squared scarf (Preferably thin)
Fold diagonal to form a triangle.
Place the scarf behind your head, with third triangle pointing at the forehead.
Bring the outer corners to the front.
Tie the 2 corners making a simple knot.
Tuck the center triangle point behind the knot that was just made.
Last, tie a bow with the two remaining corners.
The end result should look like this, you can always adjust and make the bow bigger or smaller depending on your preference.
I wear my head scarf everyday since I lost my hair, it makes me feel great when I get compliments from strangers that don't know I'm fighting cancer. I refuse to let any disease take my identity away, and no other patient should either.
