Vertical blinds consist of a series of vertical fabric louvres or slats, which can be twisted to close and obscure the window or opened wide to let in lots of light. The louvres are linked together by a chain and are operated using a cord, positioned at the far right or left of the blind. The blind can be fully opened to expose the window, by positioning all the louvres in an open position and then pulling the cord to move all the louvres to one side or other. You can choose to have your Vertical blinds split in the middle, like a pair of curtains, so half the louvres move to the left and half go to the right.
