I have an old billboard sign canvass. I tested it out last night with the projector and the picture looked great. The canvass still has a few wrinkles but it didn't affect the picture, still looked great.
I'm working on the frame. I'm using a light stand rig that is about 12' wide but the canvass is about 14' wide. I used a temporary set-up last night but planning to put a section of pvc through the openings that are already made into the canvass, worked out great already having the openings for the pvc pole. Once the pvc pole is in place at the top, I'm planning to connect it to the lighting rig using bungee cords or sturdy ties. Hopefully it will connect ok because I have a set-up Sat. Aug. 18th.
