| A studio near here wound up with a couple of extra solid core doors in their construction process, and are planning on turning them into gobos, kinda like you describe. They were already cut for windows, and will nicely match the rest of the woodwork.
In my exprience, for a good gobo, you want it to be massive and nonresonant. You want to make it very hard for sound to go through the thing, and not have it "hum along" with whatever's behind it. Solid core doors are the winners by far in those regards.
Do you have a good used-building-materials place around? |
