Drapery panels are the most traditional of window covering ideas. They are often thought of as formal, but they don't need to be. Drapery panels can be made in silk, cotton or linen and can be sheer or heavily lined. Drapery panels can block out the sun (great for late sleepers!), provide warmth and protection from drafty windows and add a level of privacy with the use of sheer panels. Decoratively, drapery panels provide a vertical line in a room, drawing the eye upward and making low ceilings look taller.
