That would be really nice to have an option to let in a little light or none. It never occurred to me to put in a double layer of roller blinds. Maybe we should put this in our house. It would give us some good privacy and more control over the natural lighting in our place. I'll have to talk to my wife about it.
Decorated with a floral and butterfly pattern in pink on a natural backing, this roller blind is equipped with a full blackout lining to exclude all unwanted light and is also available in a range of widths.
