I was wondering if anyone can help me find a supplier/manufacturer of suitable outdoor movie screen fabric in the size we need. We have an outdoor movie screen that measures 10' tall x 22' across. I have been unable to locate fabric in rolls wider than 72" (6 feet), which means the screen would have a seam running along the middle, from left to right. Our existing outdoor screen is made from an outdoor banner, and it has a seam. We've gotten good use out of it for 4 or 5 years, and it's time to upgrade. Anybody know where I can get white canvas or fabric manufactured to this size without requiring a seam? Thanks.
