In standard fabric, louvre widths come in 89mm and 127mm. There are many textures and colours to choose from ranging from sheer to opaque to blackout. All fabric vertical blinds come with a white base chain which link and hold the louvres in a uniformed order. The louvres can be stacked to the right, the left or split like a pair of curtains. If using a wand control we can only manufacture right or left hand stack not split. The controls can also be at the side you prefer.
