If you can do a basic cable then this is a great arm warmer to work on. Even if you are a beginner it's ok.....I was to when I made this. It was my first cable project. There are instructions about increaseing or decreasing the size. It's very easy.
The surrounding stitches I used was a slip stitch pattern along with a Purl1. This will keep your arm warmer where it should be. It won't turn on you. It's sturdy, it's comfortable, and won't stretch out by taking it off and on over and over again. The perfect combination!
