Josh:

Can you give a little more info on this fabric (what/where is
Malden Mills?)

I've recently moved and lost my darkroom. I need to buy some
fabric for putting over windows in the new place to turn a
room into a part-time darkroom, and of course blocking IR
is of great interest to me!

Any info on where to get rubber-coated IR-proof fabric would
be most welcome!!!

Joel.
