I’m in the process of moving, so I haven’t actually hung these yet, but I have taken them out of the package. The material looks nice and has a nice hand. I think that they’re going to do a great job in blocking light. 
I thought that I had read all of the information about them, but I completely missed the fact that they’re actually black on the reverse! Just be careful if you live somewhere with rules about what’s allowed for window coverings.
