Local historians and anthropologists, stand aside (for the quarter at least): students at the San Francisco Art Institution will be receiving instruction from Levi Strauss & Co. resident historian Lynn Downey starting today. A sustainable sculpture studio at SFAI will focus on design and recycled denim as part of the two organizations’ Fashioning the Future undertaking. Talks by a product development director and social sustainability expert from Levi’s are to precede students’ final projects – which are supposed to be zero impact – and their being exhibited at the denim giant’s headquarters in the fall.
