My entire theater fabric is from JO-Anns. Used a heavy velvet material around screen, Deep red velour on side walls frames covering my recycled blue jean material from Lowes & a very thin black material for the recessed speaker grill which sounds like your jet set material. I made cretain it passed the breath test & also held it up to the light & was able to see very easily thru it. When set on the white counter, it remained black which was all I needed. I think that any cloth that passes this test will work just fine. Also remember that one of the THX settings on receivers is to roll off a little of the high end due to the conditions of a large commercial theater, namely the speakers behind screens & cloth, and the natural tendency of a large space to absorb some of the high frequency sound. In your smaller space, there are many other concerns high on the food chain such as speaker placement & proper speaker level adjuctsment.
PS: Many new receivers also come with a mic to help adjust for tone in a room, so my advice is to find something you like & go full steam ahead.
