Venetian blinds were discovered by Venetian merchants who were traveling in Far East countries. Venetian blinds are a popular type that can be found in many households, as they are simple and give effective protection from the sunlight. The blinds consist of slats of horizontal and overlapping material. This allows for the blinds to be utilized in various fashions. For example, when the blinds are fully closed, they can completely block the external light from coming in and the blinds can also be adjusted to allow just the amount of light that you would like. What makes the Venetian blinds even more desirable is that they can be rolled all the way up if you wish to have complete light to come through your window.
