White is not just white

For me the 300x300cm material arrived first and foremost very often folded and then squeezed into a small box, which had made sure that this was completely wrinkled, ironing out makes work, but it works quite well. Very quickly, however, one has to realize that it is not, this is a pure white but rather a cotton Nature Sound. The thickness of the fabric leaves to be desired, it is very transparent, light from the back comes through a lot, so always only before dunlen / bright / uniform walls etc. use or permit any light from behind.
