When they were invented in the 1950s, vertical blinds quickly found their niche in the sprawling suburbs that were blooming around major American cities. In the land of white picket fences, vertical shades filled a much-needed space over back doors and sliding patio doors. They were a contemporary twist on traditional Venetian blinds and over time their popularity grew as did the diversity of their designs. Today modern vertical blinds have hard and soft styles for cohesion with numerous modern interior design aesthetics and décor preferences. Additionally, they are customizable in size, shape, and slat width, and so can be used on patio doors, sliding glass doors, deck doors, French doors, and wide or especially broad windows.
