Sheer Curtains are there to provide privacy within the home as well as to help accentuate your decorative style. You need to find a balance between the practical requirements of a room and matching the room’s decor. Rooms have different requirements when it comes to choosing curtains.
You may have a room that requires a certain amount of privacy from the outside world, but at the same time you still want the light to shine through during the day. Sheer or semi-sheer curtains are perfect for this scenario as you can keep them closed, but still provide light to the room. Silk and satin materials are popular choices, but you can also use voile which is a light weight woven fabric made from cotton. They are also available in many colors, but it is best to stick to bright and airy colors in order to allow as much light as possible into the room.
The advantages of sheer curtains are that you have the opportunity of layering the fabric. You could buy very light shades of sheer curtains to hang together, providing a desired mood. You could also combine these curtains with regular window treatments. An example would be to have sheer curtains hung over the window to gain privacy and blackout curtains hung in front. This would allow you to benefit from the light and privacy during the day, but still be able to close the blackout curtains when you want total privacy or to darken the room.
