Jenny saw Kristen's original Rhubarb Helix hat and graciously offered to test knit it! She chose to knit hers in Malabrigo Rios in Plomo for a prey gray-purple hat that looks great with just about everything! She loved knitting this hat and said it's an interesting pattern, yet straight-forward and simple to knit! You can download your copy of the in Kristen's , and see below for all of the materials you need to knit your own hat!
