This pattern, designed by Kristen of Marinade Designs, was part of the 2015 Tasty Tosh Collection
The Rhubarb Helix Hat is a simple yet interesting knit, and you can easily customize the length to your liking for a shorter beanie style or a hip slouchy style.
Emma knit up this quick and easy version of the hat using the limited edition "Strawberry Rhubarb Pie" colorway. This color has since sold out but it would look great in any of the Tosh Vintage
