This neckwarmer has options! The four buttons give it several styles for wearing with just a bit of adjustment. It can be a lovely thing when the temperatures change during the day. Knitting this neckwarmer is straightforward with the rectangle worked from end to end. It comes in one size and can be easily adjusted for length. We worked this in one of our favorite fibers, alpaca. We would suggest any similar worsted weight fiber except a cable plied or tubular yarn in which we did not like the look as much. A fiber that blooms makes it more snuggly.
