ok, so is there anyone out there who can tell me the proper way to clean and "de-wrinkle" blackout cloth? I've heard that it is dry clean only, that you can iron, that you can't iron. So if someone can give me an "i'm sure about this" answer that would be great. I'm in the process of sewing on a black border around my blackout cloth and in the process of this the blackout cloth got a little wrinkled, and picked up some little black fibers from the felt. ugh. Thanks!

I am also very interested in the answers to some of this. It's a bit old, but hopefully someone will come along an provide a bit of insight.

bump!
