I found a very cute pattern online, but I didn't have the right yarn, and thus the dimensions were grossly off, so I improvised.
I grabbed the last of my gray chunky yarn (I thought I had more because I so forgot that I made this cowl with it. So, yeah, I now have two gray cowls. Whatev.) and got to work. As I knit, I could tell I wouldn't have enough to make it wide enough, so I added a bit of orange for detail.
It's warm and great to wear while waiting for the school bus.
I thought I liked putting it around my head, but after seeing this photo, I don't. It should probably be wider, but I didn't want the orange to take over.
US15 circular needles 29"
1 skein of yarn (I think I used this in gray, but I don't know.)
Cast on 100 stitches, knit in stockinette until desired width, cast off.
