The Isometry hat is a unisex design that features an addicting and intuitive colorwork pattern with a simple 8-stitch repeat that is suitable even for colorwork beginners.

This pattern was originally uploaded as a fundraiser pattern (see below). It is no longer available on Ravelry, but can be downloaded from my Payhip store for free with a suggested donation.

November is Pancreatic Cancer Awareness Month, and I have created the Isometry hat as a fundraising pattern to support this cause. Four dollars of every pattern purchase will be donated to the Pancreatic Cancer Action Network (PanCAN), with the remaining dollar covering fees. For more information about PanCAN and their mission, visit their website.
