The pattern is top-down using primarily Split Single Crochet (AKA Waistcoat stitch) with a Back loop only single crochet for the brim. Using a Jumbo yarn (4-5 WPI) and 16mm/Q hook, this hat works up quickly into a thick, squishy, and warm winter beanie. Perfect for when you want a project you can finish in one sitting. If using Knit Picks tuff puff 2 skeins are needed to complete the pattern, Macro by Berroco only requires about 1/2-2/3 of the hank.
