All you need is:
1 ciput ninja (inserter, insider,?)
1 rectangular scarf
how to do it:
place your scarf on top of your head with one side longer than the other.
gather at the back of your neck and secure it with safety pin or just pin
bring the short side to your head loosely, then on top of your head secure it with pin.
Twist the long side loosely and bring to the other side, secure it with pin.
and voila! perfectly done.
