Ryegrass is knit from wonderfully squishy superwash merino. Alternating pockets of dropped stitches create undulating waves of ribbing. The drop-stitch pockets allow for a little airflow, making this a cozy but breathable three-season hat. It’s reversible, unisex, and requires just 100 yards of worsted weight yarn.

I tend to knit loosely, so be sure to check gauge before beginning.
