The Addi knits fur yarns beautifully! All of my fur work thus far uses Lion Fun Fur or similar yarns. This hat is knitted with a self-striping yarn for the body and has a furry brim. Comfy, easy to fit and fun to make. Quick, too. You will need 1 skein of Fun Fur in addition to the main yarn. Red Heart has some nice self striping yarns that may be used as the main yarn if you prefer.
