The Town and Country Basics Selena Indoor Room Darkening Curtains combine style and function. Woven with thermal insulation to provide privacy and reduced light exposure. The curtains are 95% polyester, 5% linen and feature a subtle texture and sleek lining, with eight brushed nickel grommets for easy hanging on rods up to 1.25"" diameter. For optimal room darkening, the curtain panels should measure 2-3 times the width of your window. Hand wash only.
