These curtains really do block out the light. The lining is a soft light blue (not white as I expected). But from the outside, this is not noticeable and it might have been a little stark if they had been white. I love the texture of the fabric. I did press them before hanging, but all the wrinkles didn't iron out. However, I don't see the wrinkles now that the curtains have been hung up for a while.
