I profoundly agree with looking for something that stretches, even a little bit like trico, peachskin fabric, etc....
Canvas, as most painters know, takes a LOOOOONG time to stretch correctly, and the process for doing it right, and ensuring it will not stretch OUT, is a challenge, chore and headache. Get some stretch bro.
Also, when speaking of acoustical transparency, consider that the most important consideration when choosing fabric is whether or not you like it, it is useable long term and provides "some" breath ability. The “breath ability” is not likely to be an important factor for most rooms as you do not want to deaden a room too much with fabric featuring really loose airflow. However, fabrics like thick, un-stretched canvas used to cover acoustical materials with any moisture content have a better chance to create mold. Mold=bad.
Semi transparent (slightly stiffer airflow) fabrics typically allow for lowend absorption and no menacing and harmful mold build up. They look HELLA better a year later too.
Once again, using a solid stretch fabric ensures the contents of your traps will not leech out, and that your traps will maintain a sharper, more usable appearance, longer. In some cases, (like with our fabric) the absorptive properties (or lack thereof) can enhance low frequency absorption.
Good luck, and VIVA LA DIY!
