I started the screen wall. Some of these pictures are DARK! I hope you guys can still make things out. Remember this? So far it's working out nicely.
First thing is first. I cut a section of GOM, rolled it up and put it aside for the last section around the projector. Then I took the screen off.
After I took the screen off, I laid out the fabric on the wall and use my trusty push pins to secure it. I left a few inches on the sides. I used the same technique, starting in the middle and worked in one direction, removing the push pins as I went, pulling the fabric taunt and putting in staples. You can barely make out the pins, they're clear
Next thing I did was put a few pins in the sides to hold the fabric taunt across the middle. I then proceeded to cut out the area behind the screen. I left a few inches all the way around the screen in order to use that slack to pull the GOM around the framing. I did the top and sides and left the bottom untouched initially.
I started stapling from the middle of the screen and wrapping the GOM under and around the framing and worked my way in one direction. When I got to the corner, I cut a 45 degree angle in the fabric to the corner, then finished stapling. I did the other direction, then moved to the sides and worked my way down. After completing both sides, I tacked down the bottom part of the screen so I could lay it out and cut the remaining GOM.
I trimmed off the excess and put that aside. I stapled the the GOM onto the horizontal top of the framing and removed the pins as I went. Once it was secure to the top portion of the framing, I started to wrap the bottom portion of the GOM on the underneath side. I would make slits in the GOM where it hit a stud.
Now the large area is done, I then repeated the process for the sections where the left and right channels will be located. These will be covered with panels. I did both sides and as before, I left a few extra inches where I cut it out, could wrap it, cut the corners at 45 degrees and stapled.
