Is there a fairly durable (and maybe flame retardent) fabric that I could
simply staple in place? I may want it to come down the walls about a foot
as well, as I have panelled/sheetrocked about 8 feet up from the floor and
have exposed wall above that level that would be well suited to sharing the
same covering as the ceiling.

Ideas or links appreciated.


try an asbestos curtain.
It's flame retardent.
