Roman shades are one of the most stylish and very efficient and practical way to add a touch of elegance to all of your windows.
Roman shades can be used as a standalone window treatment fitted outside the window or fitted inside the window recess and combined with curtains and top treatments for a layered look.
You can order Roman Shades to be custom made or you can do it yourself. I found very usable information:
