In my basement remodeling project, the two side walls are currently 60's era paneling. I do not know the condition of the walls underneath, but I doubt that it is anything I want to expose. (In fact, I think it may just be the wall studs without drywall.) I hate the paneling, and don't think I want to just paint it. I could put up new drywall, but I don't want to do that if I can get good results from putting up fabric. Any recommendations? Cost is definitely an important factor. Sound is also a factor, but frankly I'm not overly concerned about it. Finished room size will be: 20'x13'x7'(low ceiling). I'm particularly curious about what types of fabric can be used. Thanks!!
