Those pieces are cut from very long curtains and if your windows were of a different size we can talk about a fee for alterations, I have the skills and machines to make them fit, considering your windows are smaller than the actual size.
You can have all 6 pieces for $30 without alterations
As you can see in the picture, the lining is thick, the white part is in the side of the glass window deflecting light and the black side is in the inside of the curtain, darkening the room.
