I'm in the process of building an outdoor screen for enjoying night football, basketball games, and movies. I'm aiming for a size of about 5' x 12' to allow for wider projections. I've checked out BOC at a local fabric store, and it's both decent and affordable. I'm also thinking about other durable materials since I'll be taking the screen on and off the frame quite often. I plan to use aluminum tubing for the frame. Has anyone tried alternatives to BOC or have any advice? Durability is my main concern here. I'd really appreciaet any tips
