Introverted but willing to discuss crocheting. This mug is a great gift for someone who crochets and prefers wielding a hook to making small talk. Or a gift for yourself if you prefer yarn because it is too peopley outside. The interior is soft grey and the back features a skein of yarn with a crochet hook. Created in my New Jersey studio from stoneware clay and kiln fired to over 1900 degrees. This mug measures 4 x 4 and holds 16 oz. All glazes are lead free and non toxic.
