Measure the area you want to divide, including the height the curtain needs to be. Determine how the room needs to divide---such as one line across the entire room, or one small corner, covered on two sides. Determine how close to the ceiling you want to install the curtains.
Find the closest stud to the area where you want to install the curtain. (A stud finder can help you do this.)
Place a laser level on the stud and mark the locations for the hooks that will hold the curtain wire in place. Have your partner mark the area on additional walls while you hold the laser level in place.
Drill a pilot hole on the marks made while using the level. Screw the threaded hooks into the wall. Use a screwdriver inserted into the hook for leverage while screwing. If using small hooks, tap an anchor into the pilot hole before screwing the hook in.
Cut the fabric to the height of the curtains plus 6 inches for a seam allowance. Repeat for enough panels to cover the area you want to divide.
Fold a ½-inch hem around all four sides of the fabric and pin in place. Repeat for each panel.
Stitch the hem removing pins as you go. Repeat for each panel.
Fold one of the shorter sides over by 2 inches and pin in place. This creates a channel for the wire to pass through when hanging. Repeat for each panel.
Unscrew the turnbuckles the maximum amount you can before the screws come out.
Measure the distance from one hook to the other and add 1 foot. Cut a piece of airplane cable to this length with cable cutters.
Thread the end of the cable through a wire rope clip.
Thread the same end of the cable through the closed end of a turnbuckle, leaving about 6 inches of extra cable.
Secure the wire with the wire rope clip.
Hook the turnbuckle to one of the threaded hooks already installed in the wall. Bring the other end of the cable through the channels on the curtains.
Thread on a wire rope clip and bring the end of the cable through another closed end of a turnbuckle.
Secure the cable with the wire rope clip.
Hook the end of the turnbuckle to the hook in the wall. Tighten the turnbuckles evenly until the wire is no longer sagging.
