You know, I personally never really think to hang a curtain in the bathroom. Sure, blinds or a roller shade. But never a curtain. I do, however, love the look of these delicate sheer curtains hanging in the bathrooms pictured:
A few of the examples above are cafe-style curtains. They're wonderful for the bathroom because there isn't much length to them and they cover only the portion of the window where one desires privacy. The rest of the window is free for letting in as much daylight as possible.
Do you have curtains in the bathroom? If so, what are they like? If not, what do you do instead?
