This brimmed beanie is adorable for anyone, but also made with chemo patients in mind. It’s soft and stretchy, but lightweight, so perfect for summer or warm weather areas. The free pattern is written for adults/teen size. The gauge is written for HDC stitches from the beginning rounds of the hat. I used Bamboo Pop in lime green for the main hat and clover for the accents. For the teal version I use WeCrochet’s Swish DK in Marina and Wonderland Heather.
