My theaters walls are very much like yours. And the finished product, if done well, looks so tight and profesional. Furring strips need to also be placed under where your "picture frame" moulding is going to go. Do not attempt to glue anything to the GOM. I used a lot of staples and glue to get the furring onto the wall. Like Big Mouth said, putting two strips at the baseboard, the chair rail and the top where I planed on larger crown moulding under my sofit. Then, for each section of wall between columns, I attached only one verticle furring strip to the wall. You should allow the glue on all these strips to dry. You are going to stretch this stuff pretty tight and I was worried the strips might pull off the wall. Have some patience. The other verticle strip I would attach to the frabric first useing alot of staples. Then I glued and stapled this strip to the wall turning the stapled side to the wall, pinning the frabric against the wall. Allow this glue to dry also. When all the glue has dried, pull the frabric towards and past the first verticle strip and keeping it tight, you staple it to the side of the strip so you will not see any staples from the front. Thease should be hidden by your columns. By the way, this method only works if you do your columns after your fabric, so plan accordingly. After you stretch and attach your fabric from side to side, you can now do top to bottom easily by simply stapling it to the strips you put up before. I started on the top and pulled tight to the chair rail. And then went from the baseboards up to the chair rail. I know this may be confusing so I'm getting some pics together to help illustrate.
