This headband is worked in double knitting so it is thick and warm. It is worked in the round on a 16” circular needle and starts and ends with a decorative braided edging. While worked in one size, it is stretchy and will fit most adults. One skein each of two contrasting colors will make two headbands if the colors are reversed for the second. Cascade 220 yarn can also be used, but substitute a size 8 (5mm) needle.
