From April to Labor Day, Dumbarton House will display the “Posey Quilt,” an early 19th century American pieced quilt made of silk dress fabrics. The exhibition will highlight the eight women believed to have owned the dresses used in the quilt, as well as the Posey family and its long tradition of passing the quilt down from mother to oldest daughter.
