A life-sized cow carved out of butter is one of the many amazing objects highlighted in the State Fairs: Growing American Craft exhibition, currently on display at the Smithsonian’s Renwick Gallery. (And it’ the only one that has its own temperature-controlled space!)

Learn how the butter cow was constructed, how it is maintained, and many other behind-the-scenes details about the exhibition, from the team behind it. Mary Savig, Fleur and Charles Bresler Curator‑in‑Charge of the Renwick Gallery, will moderate a panel that includes objects conservator Leah Bright, exhibition designer Meghan O’Loughlin, and award‑winning butter sculptor Sarah Pratt. Together, they’ll offer an inside look at the creativity, conservation, and craftsmanship, that makes this exhibition a cornerstone of the Smithsonian’s 250th celebration.
