Saw some gorgeous turban headbands in Liberty the other day, got me thinking just how easy they are to DIY. Just tie a scarf or long strip of jersey or velvet around you head as if you are going to tie a bow at the very front and middle of your head. Instead of tying a knot, twist the fabric around so that each end is going back in the same direction from where they came, and tie in a bow at the back of your head. Voila! You should have a twist like the one in the second picture in the middle of your head.
