For my friend at Muffashionista. Happy birthday!
The head band was made as follows:
With worsted weight yarn and a 5 mm crochet hook, ch 12. hdc in 2nd ch from hook. hdc across (9 times), ch 2, turn. [10 hdc, ch 2, turn] until the band reaches the desired length. For a nice finish, ch 1, and sc evenly along the long side of the band. When you reach the end of the first side, bring both edges of the band together and slip stitch across through both layers to join. Continue sc evenly around the second side.
Keep your ears nice and warm stylishly during the winter!
