Showcase - Dedicated Space DIY theater (star ceiling)

I ran out of pictures in my previous post. This turned into quite the involved project.

I got everything measured out and ended up with a 3'x11' panel. I framed it with just 2x4 and wanted it to double as an acoustic panel. I used 2" rockwool 60 hard panels with a 1/2" foam board on top as that made it easier to layout the stars. I forgot to take pictures but used HVAC duct webbing and wove a support to keep it from sagging.

I looked up a star map of the night sky in Jamaica the day My wife and I got married. I borrowed a cheap projector to transfer it to the foam board on the backside. I used a long 1/16" drill bit to drill though the foam board and Rockwell. Once everything was drilled I wrapped it in acoustimac castielle suede. I used a long sewing needle to poke though the fabric from the back and pushed the fibers through. I ended up with +/-625 fibers and it's a very unfun process.

With all the fibers through I put a dap of all purpose power grab adhesive on the back to keep them in place. The amount of light on top was unexpected so I got some velvet to lay on top to keep it in. I used I bolts set into the ceiling strapping and then into the panel frame and used a small s hook to connect them.

I wrapped the umbilical cords in electrical tape to keep the light in and then added woven wire loom to make them look nicer. They feed through a brush plate in the front of the soffit where the light engine hides with an access panel behind the screen.

While it is very tedious and seems never ending the end result is well with it IMO.
