And that's that! I'm finally finished with the shelf project. I'm very pleased with the result despite having to make some design changes in the middle. That's pretty much my whole theatre though...
OK, here goes:
Install some molding 'round the outside
Also some quarter-round to cover the transition from drywall to wood
A couple coats of paint... this is the same color as the soffits.
Cut and paint the shelves (they're 12-1/2" x 5.5")
Mounted the lights and we're done! Those lights are old LED bookshelf lights from Ikea. I used my plate shear to cut them down a bit and then drilled a new mounting hole to fit the shelf.
I think the shadow lines came out quite nicely. These photos are with *every* light in the theatre on. That only happens when I'm working.
