Well, after many trials and errors, i've come back to that ol' adage; "Keep It Simple Silly!" Borrowing from many threads here, it seems the easiest way to make a masking system is by getting the 1/2" thick foam board from Lowes. It comes in 4'x8' sheets for around 9 bucks. It's easy to cut, but, if you have access to a bandsaw it makes for a much cleaner cut. What I did was cut 2 pieces 8" tall by 94 7/8" wide,(that's the width of my Carada 104" screen). I then cut 2 pieces 2" tall by 90 5/8"~ish wide piece (thats the inside width of the screen). I centered the shorter ones inside the longer ones then lined the longer straight edges up and glued them. Next use spray adhesive to cover the backside of the foam board and cover them in velvet. Now, that was easy, right? Well, after searching this site and others, it seemed the most difficult thing was mounting them to your beautiful screen without destroying it. I've tried everything, trust me. I tried small pullies, tension rods, gravity, everything. The simplest solution evaded me for months, until I went back to Lowes on a mission, a mission that lead me to a solution so simple that I curled up in the floor at Lowes and cried. There it was, the device that had eluded my mind for sometime, a freaking $3 clip.
