Old fabrics from the Textile Museum’s permanent collection mingle with edgy contemporary works in the new exhibition “Green,” which “celebrates green both as a color and a cause, exploring the techniques people have devised to create green textiles, the meanings this color has held in cultures across time and place, and the ways that contemporary artists and designers are responding to concerns about the environment,” according to the musuem. The show includes a partially disintegrated curtain that depicts a garden scene with grapes, vines and birds; it’s from 4th-century Egypt. On the adjacent wall, a “tapestry” woven from exploded car and truck tires that artist William Knight found along New Jersey highways demonstrates “how creative recycling can sublimate even the most ignoble of materials,” according to the museum. The exhibit closes Sept. 11. Don’t miss the separate but related “Second Lives” display upstairs; this show is about recycling textiles. The museum is at 2320 S St. NW; admission is a suggested $8.
