Often made of sheer or semisheer fabric, stretched curtains are a wonderful solution for French doors, door sidelights, and slim windows that do not open. Before purchasing Net Curtains it will be essential to carefully take the measurements of the window that you intend to decorate. The folds are also referred to as ‘fullness’ or ‘gather’ and can be created by adding more fabric that is two or three times wider than the window width. Don't be afraid of matchy-matchy fabrics - Voile Curtains can look great in small spaces like a spare room that isn't used every day.
