The concealment of these curtains is not 100% I would say, but still not far away. They seem to me to be quite effective at this level. As against to the waist, I have done a bit because I considered the size as it was going to take on the wall, but actually because of the fastening system, the curtain should be slightly accordion , so it occupies a maximum size smaller than its dimension. This is normal, but I had not thought, so it proved a little short for the use that I wanted to do. Independent rings, and not integrated in the curtain would have prevented this problem. I do not use currently.
