I have used the pleater tape that is sewn to the top of the drape s. It's been a while since then but you sew the tape to the right side of the drape and then turn it to the back to form the top. You can get the tape at most fabric shops and maybe on line. Like I said it was about 35 years ago that I used it but it sure works fine The drapery hooks slide into the tape to form the pleats..
