Blinds are a combination of the window shade and the shutter. Like a window shade, a blind can be raised or lowered to a specific position and like a shutter, blinds have slats that can be positioned for light and air control. Blinds come in vertical and horizontal configurations. Vertical blinds are usually used on windows and horizontal blinds (which are similar to drapery panels) work best over sliding doors. At the moment, horizontal blinds are not particularly "in," but they are functional and work well in offices and public settings.
There are many window covering ideas out there; it's just a matter of determining the needs of the space and using the right type of window covering that is both functional and attractive.
