I made a BIG fabric screen (48 feet wide, 12 feet high!) from drapery material with a rubberized backing. It's strong fabric, will hold the weight of the screen, has a tight weave (good reflectivity) and less wrinkly than muslin, etc. It weighs about 40-50 lbs - I think it will make a pretty cool screen / stage background for projection and effect lighting. Next trick - how to best hang this jumbotron. so it hangs flat in various venues. I primarily will use it on a school stage. Which has curtain rails a foot below the ceiling. so, I will probably put grommets in every 6" (maybe folding over the top 2 inches, to give the grommets a double fabric strength - maybe not needed esp since grommets every 6", but I think will be nice. Will always be used indoors so wind not a factor. Then I can use s-hooks and the little wheel curtain rail rollers to slide it around. Question 1) in this setting, best ways to tension on sides/bottom? I could wrap side ends around a pvc pipe, etc. or put grommets on side and bungee seperately to give a little more flexibility. (would need to come up with some kind of pole/stand (volleyball stand? - the old rubber tire with cement in it) on the sides, or get an elephant to hold still for 2 hours. Question 2) for free-standing applications, such as in a gym or theatre, without a curtain rail above, how best to hang, so it is flat and even? If using lightweight cable, I'd think a 50 lb screen will have some sag (not good for screens), so I'd have to have serious eyebolts into the wall / ceiling structure, basketball stands, etc. on each side, or multiple hanging points along the top hanging down from ceiling? Dont want to use an external frame that big, so looking for best ways to rig with a cable if possible. (What size cable would I need?) a friend of mine tensions a large green screen with sandbags and cheap spring clamps ($10 a dozen) in the lower corners to tension horizontally and diagonally. I'll probably use a carpet tube (3" diameter, 12' long) to wrap it on to minimize wrinkling Any suggestions / experience welcomed. Thanks!
