How to tie a turban?

How a turban is tied in Rajasthan. It is basically a long piece of cloth, approximately 15-20 yards which is wound around head at particular angle. The width is approx. 7-8 inches which is crushed and twisted around.

I am trying to carry this technique, using a long length of fabric and draping it around body to form a jacket, twisting and turning to get the turban effect.
