Starting in the photo studio, this material is excellent, value for money, ease of installation and use. The fabric is of good quality. In terms of thickness, it has nothing to do with the comments I've seen on some opinion, what counts is how to place the light and not the thickness of tissue. I discovered, for example on the net that properly placing his light, one can make a black background without black money! (On the side, the light down so I understand, and the fund goes black, tested Approved).
