Tape headed curtains are a quick, simple heading option. The tape forms a pencil pleat gathering and is used on many pre-packed curtains, as it is machined in place and gives the option to gather the cords to the required width. It is assumed that less fabric is used when a tape heading is applied, as you can draw the cords looser than suggested- enabling you to fill the width of the window with less fabric. However to get the best appearance you should have the tape cords drawn to the maker’s instructions to form a tight regular pencil pleat.
