A few weeks ago I went camping in Joshua Tree and was wishing I had a nice, cozy, knit hat to keep my head warm during those cold desert nights. Once I came home, I immediately set to work creating this versatile, unisex hat pattern. This pattern features a ribbed brim, optional pom pom, and beautiful, yet simple diagonal rib stitch pattern. It is constructed from the bottom up using medium weight yarn and size US5 knitting needles.
