I made this headband out of my handspun yarn. It's 3" wide and 20" around (stretches to fit my 24" head). It's knit as a rectangle in stockinette stitch with a slipped edging, and the ends are grafted together.
Here is the yarn before being knit up, it's a 2 ply bulky weight spun from a black and white striped roving.
It took me about three hours to spin the yarn, an hour to ply it, and two hours to knit the headband.
Hope you like it! I'd be happy to answer any questions
