Roman shades are made with a continuous piece of fabric. They use a pull cord attached to a plastic ring to lift and lower the blinds. After continued use, the strings or plastic rings may be become worn down and break. It is possible to repair the Roman shades yourself with replacement parts and get your shades working like new again.
Remove the shade from the window by loosening the screws on the mounting brackets with a flat screwdriver or hand drill. Place the shade face down on a flat surface while it is completely extended.
Search for the damaged rings or broken cords. Untie the knot in the pull cord and slide the knob off.
Untie the knot in the string at the lower ring of each vertical line. Pull the rings and broken cords out. Hand-sew new rings in the same place of the old rings by sewing them into the lining and the top layer of fabric.
Replace the broken cords with new cords. Start at the bottom of the shade and tie the new cord to the ring. Wind the new cord through each ring in the vertical line and the eye screws that are horizontally installed across the shade. Allow for about 36 inches of cord to hang down on the side for the pull cord.
Align the ends of the cords and cut the ends with scissors so they are even. Feed the cords through the opening in the pull knob and tie a knot in the end.
Hang the shade back on the window. Lift and lower the shade to make sure it works correctly.
Use nylon cord because it is stronger than cotton and will most likely last longer.
