The Town and Country Luxe Oslo Double Layer Indoor Room Darkening Curtains combine elegance and functionality. Woven with thermal insulation to provide privacy and reduced light exposure. The two-layer curtain panels offer both sheer and room-darkening options, with a subtle lustrous sheen and eight brushed nickel grommets for rods up to 1.25 inch diameter. For optimal room darkening, the curtain panels should measure 2-3 times the width of your window. Hand wash only.
