Michael,I'm in Australia so the lining that we got from the curtain maker may not be available in the US but similar products under different names should be.
The lining I got is called 'Bumph". It's a loose weave woolen stuff and, if anything, it looks like a speaker grille cloth made out of wool so the threads are thicker than the fine threads of normal grille cloth but they don't press tightly together and you can see through it a bit if you try. Because it's so loose, it needs to have a backing sewn to it or it won't hang properly by itself. It's expensive as curtain linings go but that doesn't equate to your $850 a metre - it cost me $450 Australian which is probably around $300 or so US at the time - to have linings to cover a space around 10 ft wide floor to ceiling, say 7.5 feet high. That covered making and hanging. The actual width of the lining, spread flat, is probably around 1.5 to 2 times the actual width of the area covered since it hangs in folds which gives you more surface area and increases depth from some angles, all beneficial to absorption.
The stuff doesn't look bad on it's own, apart from the fact that it only comes in one colour which is a pretty dull cream, but since it goes behind the curtains you never see it anyway. My actual curtains are probably a bit more reflective than I'd like since the weave of the material is a lot tighter than the weave on the Bumph, but they did provide some absorption. The Bumph increased the absorption by a very noticeable amount. I understand the stuff is intended to be used to stop noise entering through windows so it's the sort of thing you use if you live in a noisy area, but it really doesn't matter what direction the sound is coming from as far as absorption goes.
I'd look in stores which sell curtain materials. We had just bought a new house and were getting curtains for it when I noticed the material and asked about it. I didn't get it originally and just went with straight curtains, but went back later to get it when I decided I could use a little more absorption and that this seemed a good way of being able to get it without it appearing obvious. In use as intended it's totally invisible since it hangs behind the curtains out of sight.
