I am planning to construct some ceiling details to replicate a starship ceiling. This stuff will be hanging above my head from a suspended grid framework. Plastic or foam seems to be the lightest weight material. Once again, I use a vinyl gutter as a base.
Why did I pick a vinyl gutter? I can get a 10ft piece of this stuff for only $5.23 and it is much cheaper and lighter than wood. After the photo, I chopped these up.
Below, I have just used the gutter "corners". I liked the 45 degree angle of the edges, and I made some more 45 degree steps in it lengthwise as I cut it.
I have temporarily hung these Franken-gutter pieces up to check for scale. They are zip-tied to the grid. There will be a piece of Sintra in the center of those, a panel between the rails. That will hide the rope light. There will also be some lenses made out of white Acrylite, some little red lights, some little white lights. I also temporarily hung my round fan grille to see if it would be centered over the top of my computer chair. Everything on the ceiling is going to get painted a dark charcoal color. There will be a lot of box shapes up there, with horizontal tubes and random plumbing and wires.
Next time, let's cut up some Sintra (PVC board) and glue these gutter halves to the edges. The center section will be 21.5" wide and 10 feet long.
