You need to use blinds or shutters, yet neither one of these options offers you an elegant look or even choose your décor in the most cases. Curtains and gently drapes are often the best choice as you can quickly match these with the remaining décor instead of using simple colored blinds that do absolutely nothing for the feel of a room.
If you happen to have a bay window in the center with standard windows on both sides, you are able to create a wonderful sitting region that will be comfortable and beautiful at the same time. For the bay windows, have curtains that will slide just to the window chair and for the other windows have similar style and color curtains fall all the way to the floor. Now, when you open the drapes or curtains it will have an amazing effect of the entire room.
