I made this to match the evening mitts. You can wear it as neckwarmer, or double it lengthwise to wear as a head band.
Easy Neck Warmer
Worsted weight yarn
Size 5 needles -- straight or circular
Provisional CO 32 stitches. Knit every row until you have 14 inches of knitting. Remove provisional stitches onto another needle, and work a 3 needle bind off to finish. Weave in yarn ends. This is a quick project!
