These velvet drapes are just what I needed, but they are not what I consider room darkening.  They do not have a lining and the light does come through them but they do dim the light about 30%. I left up my room darkener shades underneath. Fabric is soft and luxurious.  Very wrinkled from package so  put them in cool  dryer with wet towels but still had to iron from wrong side and got most of the wrinkles out.  Hopefully the rest will fall out eventually
