If you are looking for a very professional looking way to tie a scarf (a method commonly used for business and uniform attire) then the "Light Queen" wrap might be perfect for you.
The scarf is tied similar to a men's necktie. The pashmina is rolled up diagonally to create a narrow scarf. Usually it is wrapped two to three times around the neck but the number of wrappings is personal preference and also depends on the length of the scarf used. For a more detailed instruction on the "Light Queen" wrap please see the detailed diagram on the right.
