At the opposing end, the one nearest the window frame, detach the three tape cords. Draw in these tape cords, spacing out the pleats evenly as you do so.
When drawn to the width you require (half the track width plus five centimeters) tie the three cords into one knot. Don’t cut these cords as you’ll need to untie them to stretch the curtain flat for cleaning.
Insert the plastic hooks on either the centre or bottom row of the curtain, spaces at approximately every four pleats. The hook is inserted upside down and turned over. Finally, insert the hooks into glides along the track length. You may iron the curtain with a cool iron (fabric side up) if the care instructions allow this, otherwise simply hang as is.
