Today at the last minute, as usual, the client in our black box space told us "btw we have this 12'x9' piece of cloth we need you to hang as a projection screen." I am from an electrical background and know very little about hanging soft goods from a truss system. My limited experience tells me two pipes would work the best. PROBLEM no pockets for pipes. We hung is from three point across the top and then two and the bottom. The theory was to pull it taught with four lines on the four corners and the fifth line to support the middle at the top. It looks really bad and I was wondering if there is a better way to hang such a cloth so it hangs flat and taut. Is there a better way to hang the make shift screen?
