This hat is a great beginner's knitting project. It's fun and fast to knit! You only need to know the very basic knitting stiches: "knit, purl, and k2tog." Please try it out with using luxurious 100% Yak Down yarn from Shokay. PLEASE NOTE: Individual knitters may sell a hat made from this pattern. I just ask that you credit me as the pattern's author and include a link to my Etsy shop in your listing. Thank you!!
