I'm sure glad I got blackout curtains. Mine are white on the outside and dark brown on the inside. From JC.Penny. Mounted on outer of 2 rods. The inner rod has curtains that are more sheer. This way I can control how much light I want in the room. Total blackout, to light through sheers, to no curtain for max light.
