Slim, I would guess that you are taller than average. Are you near 6 feet tall?
Addy, Did you know that the human body has some divine proportions? One's arm span is about the same as one's height. A scarf that is as tall as the one wearing it will fall to about finger tip length when draped around one's neck. A hand width is about equal to the length of one's neck. I like a width that is about the width of my hand (about 5 inches).
A long scarf can be folded in half by length to make it double thick and warm. If the scarf is as long as the person is tall then the half length is just enough to wrap around one's neck with a hand length to pull through the loop made by the fold.
I once lived in the snowy, northwest corner of Pennsylvania, USA, I know scarves pretty well.
And we again have about 5 inches of snow on the ground here in North Carolina. Nice scarf weather.[/COLOR]
