If your windows are small and need the maximum amount of light then it is best to dress your windows with a vertical blind. The absence of curtains will enable more reflective light to enter the room, especially if a white gloss finish paint is used on the window sill and window surrounds. A light coloured vertical blind such as this plain beige can then be used as your window treatment, as it will fold neatly to one side of the window taking up the minimum amount of the valuable window area.
