Pencil pleat curtain headings are popular because of their flexibility. You can gather the curtain to fit whatever width you desire and they can be hung from any curtain track using hooks or from a curtain rod using rings with hooks. Pencil pleat curtains have a tape running through the top of the curtain head and cords which run along the top of the curtain. These strings can be pulled to achieve the desired gather and curtain width - whether their purpose is for fashion or functionality. You can choose pencil pleat curtains for either poles or tracks.
