If you are tired of those fabric-covered or wooden vertical slats on your vertical blinds, you can keep the headrail, remove the slats and install drapes onto the vertical slats. This will allow you to open and close the drapery just as you used to open and close your vertical slats. Fortunately, this conversion is reversible in the event you decide you want to reinstall the slats.
Close the slats on the vertical blind. Inspect the anchoring system for the slats. Most anchors are plastic clips that fit over a hole in the slat. Spread each clip apart slightly with the tip of a small flat-head screwdriver to release the slat.
Count the number of retaining clips on the headrail and then measure the width of your drapery with a tape measure. Divide the width by the total number of clips. You will use this number to determine spacing for your drapery.
Place a mark approximately one inch down from the top, and space each mark according to the number you obtained in Step 2. Punch a hole through the drapery material with a fabric hole punch over every mark on the drape.
Spread the retaining clip apart at the far left of the headrail and then slide the drapery into the clip until the center of the clip rests in the hole. Repeat the process at the other end of the headrail. Your drape is now secured from both ends.
Secure each additional clip to the holes in the drape as you work your way across the headrail.
