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.
The fullness of a pencil pleat curtain will vary depending on the amount of gather you create with the pull cords. Generally speaking, we recommend 1.5-2.5 x fullness, meaning that 1.5-2.5m of fabric is used for every metre of track or rod.
