I made two neckwarmers over the winter (I was never fond of scarves) and just finished a third, lighter version. I wanted something I could cram down the neck of my jacket that would block the wind but not be too hot.
Here's the first one, it's more of a cowl, really: bulky and shapeless.
The second is my favorite. It's loosely based on this pattern http://www.needlebeetle.com/free/nw.htm
If it looks a little stretched out it's because I made it to fit myself but my much more photogenic (if slightly larger-necked) BF is modeling.
The third I knit in garter stitch with short row shaping.
That's it. Just some FOs; I thought I'd post for closure.
