Join the Prospect Park Alliance and Wildlife Conservation Society for a weekend of fleece fun. Visit the Zoo, where the sheep will lose their winter coats in preparation for summer, and enjoy woolworking demonstrations, crafts, music and, of course, sheep! At Lefferts Historic House, learn how wool was used on a 18th century Flatbush farm. Brush wool with carding paddles, spin yarn using a drop spindle and even make a felt ball to take home. On Sunday, visitors can also enjoy a demonstration by our resident spinner, Catherine Conrad.
