Sheep are traditionally sheared in late spring as the warm weather arrives. "Felt" will feature a sheep shearing (live sheep!) by farmer Joe Sanchez; bicycle-powered wool carding by Oakland-based felt artisans Felt the Sun; the making of a giant felt rug with artist Ashley Helvey; and a short talk by Ariel Rivers about her family's sheep ranch. Presentations will be followed by a screening of the acclaimed documentary Sweetgrass (2010), directed by Lucien Castaing-Taylor and Illisa Barbash, about the last major sheep drive across America's Big Sky Country. Leave your winter coat at home.
