I have a 20’ x 40’ piece of fabric that will be hung on a a batten with grommets and tie line. It will be folded into 4 so that there are (4) 10’ x 20’ drops. The plan is to have an actor on each side and pull to reveal a drop. My initial thought was to use Velcro (2-3’ piece) at the tops and center. There will be two reveals or two actor pulls. My concern is that we don’t want the actors to pull and reveal the last panel because the yanking force may reveal the last panel rather than panel 1, 2, and 3. Any tips or has anyone done something similar?
