I didn't do the whole width of the room as I have a funny shaped room and just built the pelmet as a rectangle to frame the room and ceiling. Plus it would have cost too much.
I've got loads of fotos somewhere, I will fish them out this week.
Tips:
Panels - I used 5m foam from HobbyCraft in future I would use something thicker as they can be a bit 'saggy' when you attach the A3 boards together to make a larger panel. I stuck x4 A3 boards together to make a large board and then attached the black fabric with contact adhesive. Make sure you glue every bit of the fabric down otherwise it will rip when you drill.
I then repeated this x4 times so I had four equal-sized panels (probably 1.5m x 1.5m) which I then fitted (via black screws) to a timber battened frame screwed to the ceiling.
Don't even think about using magnets, they are a complete faff, cost a fortune and once the star ceiling is up you will never really need to take down anyway.
Drilling - When you drill the holes for the fibres you will likely rip a few bits of fabric - try to drill slowly (and not with a Dewalt power drill) and do it from the rear side of the panel (i.e. not the fabric side). I made a match-box sized panel to test on a few times until I was confident. I made a few screw-ups but a black Sharpie fixed that.
What took the most time - Drilling the holes is a faff as I had 100-80 per panel. Room wasn't perfectly square so the last panel needed taking down and trimming up several times - I still have a bit of a sag now I need to fix. Making one large board out of x4 A3 boards was a faff, especially taping them together. If I did this again I would get some 12mm Celotex and cut to the required size, it would have saved me half the time.
Useful threads:
Hi, is anyone using magnets for their MDF pelmet design? I have a simple L shape design with a gap at the top of the L for LED lighting. The bottom part of the L will be securely fixed to a batten the wall. See below. But am thinking i might need the front to be removeable, fixing cheap led...

Think there's some pics in my thread here but I never got around to updating it -
AV room / Lounge with pelmet installed (WIP)
Kit as follows:
Boards -
West Design Black Foam Board A3 5 Pack | Hobbycraft
Fabric -
Black Polyester Crushed Velour Fabric Pack 152Cm X 2M | Hobbycraft
Glue - Any contact adhesive from Amazon / Hobby Craft
Fibre controller -
MiniLED550 twinkle or colour change light source
Hydra-6 Connector (connect multiple fibre panels to controller) -
The Hydra fibre optic system
Panel tails (attach to panels) -
Panel tails with 100 mixed diameter fibres
Carrier Tails (connect panel tails to controller) -
Carrier tails
Wiring kit to wire into ceiling rose (don't really need this but I didn't have a power socket in the pelmet as this is where the controller is housed) -
Hard wire power supply
Note: I bought a Hydra-6 (with 6 light outputs) so I have 2 spare if I ever want to add more to the room.
You can get cheaper kits from Amazon but I liked the way the Starscape kits are modular. Simply affix the MINILED550 controller to the ceiling, install the fibre on the panels, plug the tails in and then connect all panels together to the MINILED550 using the Hydra-6.
Once everything was fitted it took about 10 mins to install and working.
