I read through the thread and, while it was touched on somewhat, I am wondering how large a screen you could build with spandex that is 60" wide. Obviously it depends on the material, but in general, how large can you reasonably go? I think I saw someone suggest that the Milliskin could stretch approximately by 1/3, which would be to about 80" in terms of height (I could be mistaken on that). Is that the actual screen height or would it be smaller to accommodate attaching the screen to the Screen Tight? On a 16:9 screen that's approximately a 165" diagonal. The height is obviously the limiting factor in the equation.
