I put some curtains in my room today. I want to build some acoustical panels for the room and think the fabric the curtains are made of would look nice. The room is very formal so I do not want to use burlap. The fabric is 100% polyester. If you hold it up without the lining you can see alot of light through it, it is also very easy to blow air through it. Do you guys think it will work. thank you in advance.
