I need a very specific sized screen (12ft wide 32:10), so I think I am going to have to build it myself. My question - I imagine that much screen material and/or screen paint is going to be expensive, so I was thinking about alternatives... I know some people have achieved decent results with blackout cloth.. I was thinking of taking a trip to hobby lobby and buying a sample of different cloths/materials etc... Are there any unique/clever materials people have used to make their own custom movie screens? I find it hard to believe that these 'screen companies' have a monopoly on 'reflective material', there must be other stuff out there...
I was thinking glossy poster board maybe? Or do you think you would see the seems where two pieces meet (since there is no way I could find a 12ft piece of anything)? Sure it might look kinda ghetto with the lights on, but once a image is being projected I doubt you would be able to tell it was not a contiguous piece.
Thanks for any ideas
*BTW this is for a LG PA70G LED projector, if that matters.
