Cheap alternative to PVC covering

Actually, I would have liked would this not so expensive, heavier and therefore nothing for mobile use a white PVC covering mounted. I have received the white background of a week and am very happy with it:

+ Opaque; even with dark background such as parquet floor, etc.
+ When tensioning the cloth hanging from the ceiling to a few feet on the ground perfectly *

* Just a note about the wrinkle problem: when the cloth loosely sags and the lighting is good you do not see the wrinkles anyway. The brightness itself is so controlled by the aperture, so always make sure that the studio is abundant lit ---> in search of the camera just needs to know everything appear succeed each photo, no matter who or what is being placed in the White ;-)
