Re: What to use to attach Studio Foam?
Velcro, double sided tape. You could run a screw with a small washer through it and into your wall. Depends how permanent you want it.
You could tape the foam to a stiff cardboard backing and use it as a moveable baffle. Use your imagination. That stuff is a rip off if you ask me. They charge you an arm and a leg for that stuff and to me it's no different than stuff I throw away when I get something shipped.
