To knit an ear warmer, first choose your yarn
Because you are going to be wearing this close to some pretty delicate skin, you want to choose a yarn that is nice and soft. I wouldn’t recommend a really rustic wool for this project.
After you choose your yarn, choose a pattern
Your next step is to choose a pattern. If you only have one sock pattern, the choice is easy. For my ear warmer, I used the stitch pattern for my Crème Brûlée Socks, which I also used on the Arroyo Verde Mitts. What can I say? I like a matching set.
Now the fun part: knit a long tube. To start, cast on the same number of stitches that the sock pattern recommends. I did mine with 60 stitches, which comes out to about 7.5 inches wide.
