Totally in love with this original idea of window treatment in a bedroom... Instead of the usual curtains, the owner used panels of skaï - or synthetic leather - that are simply attached on top sides with grommets, one side stays locked, while the other side locks and unlocks in position to filter the light. Not sure this would work for an everyday bedroom [i.e. doing the lock/unlock maneuver every night would drive me nuts] but great for a guest room or a room where you occasionally need light filtering, like a media room. Brilliant if you ask me!
