Hi - I'm looking at sheer curtains from both pottery barn and restoration hardware. I see someine posted on this topuc 16 years ago but I was wondering if people today have a different view. And for anyone who has bittery barn brass hardware installed, does it maintain its color or has it blackened over the years? For rh, I was told to get the clips vs rings because of the thinness of the material. Do those look ok? tyia!
