Norwegian reader Koenraad De Smedt reminded me that I've been too obsessed with silk scarves to illustrate the warmest way to wear a wool or cashmere version. That's the braided knot, as seen in the photo of Mr. De Smet himself, a symmetrical masterpiece that stays reliably in place.
The difficult to describe braid takes a little practice but once achieved it's easy to remember. Leave the short end of the scarf to dangle on your left side and wrap the long end around your neck. Bring the long end over the short end in front of you and wrap it around your neck a second time. Pass the remains of the long end between the two wraps so that it hangs in front of you.
You may need to experiment until you get the two ends to be approximately the same length.
