Shades, as the name implies, provide shading coverage of a window opening. Shades can be installed inside the window frame, or on top of the frame. One of the most versatile window covering ideas, shades cover the gamut from the basic rollers made from paper or vinyl to more hi-tech solar shades, which block out harmful UV rays and heat while letting in filtered light. Generally speaking, window shades move up and down and when lowered, cover the entire window opening. There are beautifully designed and ornate fabric shades that look more like a stationary window valance, but can be raised and lowered.
