The Finished Product

Here's the screen framed out and finished.  Unfortunately, I didn't take pics of the construction of the borders.  They are created from 3 1/4" base molding.  Basically, the widest I could find at Home Depot.  There are four distinct pieces that have been mitre cut, with velveteen wrapped and glued on.  The borders are important, as they define the screen size.  They also hide the frame and masking.  They are attached to the frame with industrial strength velcro.  They are easily removed if required.
A second picture of the screen from an angle.
A picture of the screen with the masks pulled.  Although the camera is causing some of the distortion, it is noticeable that the line created by the bottom mask is not entirely straight.  I'm planning on redoing a couple of aspects of the masking.  The good thing about the velveteen is that from a distance, you can't really tell where the borders end and the masking begins.  You actually have to get fairly close to see that they are distinct.
Looking at the screen from straight on and a distance, it's hard to tell that the border is about an inch off of the screen surface.  This is a shot up close looking along the screen towards the upper right portion of the frame.  The other thing that this highlights is the fact that the frame isn't painted yet.
Here's a shot of the frame from the side.  You can see the border attached to the front of the frame and the screen board sitting in the slot of the frame.
