You can use blinds or shutters, yet neither one of these options gives you an elegant look or even match up with your décor in the most of cases. Curtains and shades are often the best choice as you can very easily match these with the remaining portion of the décor instead of using simply 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 can create a wonderful sitting spot that will be comfortable and stunning 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 to the floor. Now, when you open the drapes or curtains it will have an amazing effect of the entire room.
