With all respect to Mark, I would say that using curtains as screen masks is adequate. IMO, it is better to use flat velvet-wrapped panels that "hug" the surface of the screen. My CH screen is a painted white wall framed by a Makita-based twin track drapery system. And for the masks, I mounted a custom third track flush against the upper screen mask. That allowed me to hang my masking panels from the inside third track where they can roam back and forth, riding along very close to the screen surface. The masks are physically connected with medium sized cable wraps to the motorized transport on the twin-track's inside track (which because of my added custom track is really the middle track).
So the motorized movement on the middle track is transfered to the panels riding on the inside track. The panels are quarter-inch black foamcore completely wrapped in black velvet. Each panel is about a foot wide and covers the entire vertical height of the screen.
My draperies are on the other (outside) motorized track. The Makita kit comes with a twin track controller ... so I can move the drapes independently from the masks.
Now I know that the Makita kit I use may be out of some people's budget. But my point is simply that I think screen masks work much better when they are solid panels with a nice sharp edge ... and they should float no more than about a half inch from the screen service.
