Can someone tell me how to build a lightweight gobo that could be easily hung from the ceiling to form temporary walls to improve symetry in an odd shaped bedroom studio? I dont know if lightweight and gobo belong in the same sentence but I prefer not to use MDF or any other heavy materials that would necessitate using wheels to move these gobos around the room.
Would rigid foam 2 inches thick and measuring 2 feet by 8 feet and faced with 2 inches of 703 (or mineral wool) work. They sure would be light and could easily be lined up to form a temporary wall.

I've never tried that, but the foam would definitely be light. The downside is that it might resonate at audible frequencies, and it won't do a lot for other than mids and highs - should help things like flutter echo though... Steve
