Hi: make your tab drapes the usual way only the tabs would be around 3" longer to make room for the scrunchy.

For the scrunchy take a piece of fabric around 8" wide by 9 - 10" long. Put right sides together and sew down the length of the fabric making a tube. Turn right side out and press, so that the seam is in the middle of the tube. Run a gathering stitch down both ends of the tube. Gather them up to the depth you want the scrunchy to be and then sew them together (right sides), turn and slip over the tab and tack in place.
You made need to play with the size (length and width) of the scrunchy until you get the look you want.

Hope this makes sense.

Bonnie, thank you for the help. I wouldn't have thought of making tab drapery first. I thought I would have to do several individual panels, hang in half on the rod & then put on some kind of scrunchy on each panel top.

Once again, thank you.
