This Pattern is written to fit most standard adult size heads. Measurements may vary. Pattern is written in US terms. It is beginner. meaning the pattern consists of beginner stitches. Pattern is worked in rounds from the top to bottom. Chains at the beginning of a round do not count as a stitch. At the beginning of every round, you will begin in the last stitch you made. You will turn your work every round until you reach the last 3 rows of single crochet. See the first photo at the bottom of this page. I do not have a tutorial to SC in in 3rd loop or a magic circle ring. However if you need to know how to, please feel free to contact me and I will be happy to walk you through it or there are tons and tons of YouTube tutorials. This beanie is more of a fitted beanie. If you want it more slouchy, you can add more rows if needed until it is its desired length.
