Cafe curtains are used in eateries as well as in the home. Typically they are hung in the middle portion of the window. This way the light can come in through the top of the window, yet prevent anyone from looking in through the bottom. You can purchase them with a top portion that will work as a valance or swags.
Another use for the cafe curtains is that if you can cover windows in your kitchen door with them.
There are multiple styles such as country, shabby chic, retro, modern, cottage, french cottage, among others.
