I needed some new curtains, and I need lined curtains as the rising sun always disturbs my sleep.They were meant to go with a blackout blind and stop the smallest amount of light still getting in. When I got these curtains I was crestfallen.. The black silk face appears solid under the bedroon light bulb but is gauzy when backlit by sunlight, and the lining is tranlucent like crepe paper! Even both curtains hung one over the other isnt enough, and this was done when the sun was setting (on the opposite side of the building-indirect sunlight!) to give you some idea of how thin they are.
