VERY easy headband: chain amount desired to fit around head and join in circle, Round 1: hdc around Round 2 to Round 11 (or to desired width): hdc around in 3rd bar of each hdc (behind and below the two bars you normally crochet into)

One side will have a “knit” look and the other side looks nice as well. I made this headband along with matching boot cuffs for my daughter and she actually prefers the “wrong” side.
