Crochet mug reads: Crochet keeps me from unraveling. Great gift for someone who preserves their sanity by wielding a crochet hook and turning yarn into amazing things. Back features a ball of yarn and hook. Interior is turquoise blue. 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. This item may be placed in the dishwasher or microwave- made to be used and enjoyed.
