Thea Sunshine Alvin doesn't consider herself unique, but she's anything but ordinary. She has a hammer called Garfield (because it's fat and likes lasagna) and with it she builds round chimneys during Vermont winters. Her stone work dots many corners of the world and is extraordinary to behold—arches, spirals, gravity-defying shapes made out of tons of rock.
Thea is also an instructor at Yestermorrow Design Build School in Vermont, which offers courses in sustainable design. Her instructor profile says she's been a professional stone mason for 25 years.
