I only use curtains if I don't want to see something out a window, like construction at a new building site. Then I use semi sheer and go up half to 3/4 high using a tension rod. I have venetian blinds (I know some people don't like those either but I do) in front of them and adjust according to the light. I think curtains are distracting otherwise. They collect odors and dust. I find curtains depressing and maximalist rather than open, airy and fresh.
