Today I finished my Herringbone Hat. The herringbone stitch is a very dense stitch, so this hat will sure keep you warm. For my hat, I used Lang Yarns Omega + yarn and a 5.0 mm crochet hook. The pattern is available in women’s size, men’s size and children’s size.
You can find the free crochet pattern of the Herringbone Hat on the website of Naztazia. There is also a very clear video tutorial of the herringbone stitch.
