Have been surprised how many don't seem to know this one, so here is how the real ones out on the Northern Plains do it in part, get out yer silk neck rag and follow along.
Lay it out flat:
Make a triangle:
Grab the bottom point and fold it over twice:
Wrap it around staring at the front of yer neck:
Pull the ends around to the front:
And tie:
The several layers of loose silk are warmer than wool scarves and not nearly as bulky.
Thousands of working cowboys can't be wrong.
Of course they also like Carhartt.
