Curtains hung on a traverse rod open and close when you pull the curtain cord. The amount of your curtain cord will be dependent on the width of your window, so you may have to shorten it. If you use a tension pulley with your drapes, you need to shorten the cord to ensure the proper tension is set on the cord. Shortening the curtain cord may also keep the cord in the reach of small hands and avoid heartbreaking accidents.
Pull the curtain cord and open the drapes so that the master carriers are to the far left and right on the curtain pole. The master carriers slide across the traverse rod when you pull on the cord, pulling the drapes with them.
Face the back of the master carrier on the ideal side of your pole. Look for the two cord knots on the carrier.
Grab the left knot with your own hands. Pull the knot to shorten the cord to the proper length.
Tie a brand new overhand knot in the cord at the carrier. Use scissors to cut the excess cord in the carrier.
