Yup, that is Silky Faille...
Wrinkled and poor air passage...
They still work well enough for our needs.
The low air passage, slightly inaccurate colors, and wrinkle removal concerns (which can be overcome with steam or wrinkle release) were reasons I went with Performance Knit. I wanted the best acoustical fabric (our human ears probably can't tell the difference though), and needed colors that would match other colors (like wall paint, star ceiling paint, etc) in my room.
I dealt with the slightly extra work of the stretchiness of the PK to get the acoustical performance and colors. The PK is easier to straighten or adjust than the SF, but the SF should remain more straight to begin with.
Pros and cons to both. Buried in this thread I've done extensive write ups about them both and the testing that was completed. People have success with both, so I don't get too excited about offering other insight/perspectives. Just seems to muddy the waters and make people second-guess themselves. Interestingly, those tests showed that from an airflow (theoretical acoustical transparency), the best is Performance Knit, then the original Kona Cotton (what they used to use at the beginning of this thread, but colors are washed out), and the worst is Silky Faille. I made a joking comment that if I was being held captive by kidnappers, I would want the PK over my mouth to be comfortable, the Kona if they want to prevent me from easily breathing, and the SF if they want me to pass out. Again, that said, for acoustical panels, other tests were done to show that the SF did fine for allowing absorption. I wouldn't want to use it as an acoustically transparent screen or something where you need to pass as much through it as possible, but it did "ok."
Use some steam/wrinkle release spray on the SF, get another set of hands to help stretch and hold it while you staple, and you will be fine. (Trying to be reassuring, but I know sometimes I fail.)
