Introverted but willing to discuss sewing. This mug is a great gift for someone who sews and prefers keeping things in stitches to making small talk. Or a gift for yourself if you prefer needle and thread because it is too peopley outside. The interior is soft grey and the back features a needle and thread. 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.
