So as winter is settling in I figured it was time to knit a warmer style cowl. I've taken my design from the cowl section of my winter hoodies http://www.etsy.com/listing/57924851/cream-chunky-hoodie-cowl-balaclava-cause and folded the collar over, giving extra warmth.
What I find with a lot of cowls, or indeed scarves, is it's always tricky covering up that tiny section in-between your jacket and the cowl/scarf.
So with this design, it simply tucks under the jacket, no added bulk, but complete warmth. the back section, only covers the neck, so you don't have a huge excess of material getting in the way of your hair (always a problem for me with such long hair - if I have excess material and a hat, without doubt, the end result is tangled, knotted hair).
