I thought about this request for a while. I was thinking dickey, maybe buttoned in back. Garter stitch flap, brioche stitch neck. Or a gaiter. I called Hunter, who was on his way to the wilds of Canada to hunt caribou. (Hunter is no slacker when it comes to hunting.) He nixed the button in back idea. He nixed the dickey. He wanted it to cover part of his back, too.
I didn't tell him that they make camo yarn. Actually, I have some camo yarn. It is an alpaca/acrylic/wool blend. It might be ok for this gaiter/cowl/dickey thing. However, I'm afraid it is itchy.
Besides being given the vague instructions, I was informed that he bought just the thing, for the Canadian trip. I'm sure it is fleece. I'm sure if I can see it, I will get a better idea as to how to construct one like it. I'm also sure you are wondering why I am still pursuing this, since he HAS ONE. Why?
Hunter said, "You could make me a lighter weight one for hunting at home." Really, I'm having fun doing this.
