I have never seen nor touched a muslin backdrop and was wondering if they were a heavy material or not. I was thinking of using them to drape some walls in my basement to cover the concrete in my home entertainment area (not quite photo related). I was hoping to find a material that is a bit heavier to absorb some of the sound. The muslin backdrops I've seen for sale on ebay claim to be heavyweight and they are considerably cheaper than buying fabric at the local fabric store.
Anyone give me an idea on what to expect if I ordered one?
