Curtains that cover the whole window and that are retrieved with embrasses on both sides make the window look narrower. Would you also like the window to look lower and make the room more intimate by tempering the bright daylight then a combination with blinds or roller blinds is a good choice. Choose for illuminating fabrics otherwise the room will become very gloomy and it will work diminutive in the interior.
A window appears wider when the curtain generously runs through on both sides of the window in front of the wall. The best effect is achieved when the curtains runs through from wall to wall, if possible.
A window appears higher if the curtain runs through from floor to ceiling. A window appears less high when a wide coving is installed above the window, possibly with lighting above the cove for an even greater effect. Vertically striped curtains make a room appear higher, and horizontally striped curtains make a room look wider.
