Originally I tried using a staple gun but the staples pulled out of the plaster ceiling pretty quickly, even though he wasn't tugging on it. General use to move it out of the way close to the wall (when I would stop in) was enough to pull it down. So I drilled small holes up into the concrete, inserted rawl plugs, put a small hole in the fabric with the screw and screwed it to the ceiling. Stayed secure after that.
