I agree with your points.
But I am just playing around just now and for simplicity will only
consider the curvature of the fabric.

That would be changing the criteria. :-)
I will keep the randomness but try to make the transparency somewhat
dependant on the viewing angle. My first thoughts are nested texture
maps with the transparent lower ones using the aoi feature.
My tests with just aoi gave a too course pattern.
Thanks to both you and Alain.
