Hi, I have a bit of a dilemma with what to do with curtains in our master bedroom. We have a 2700mm stud at the window and little to no room on either side of the window that starts at floor level. There is also a very large, very bright park/street light outside. I have roller blinds for a bit of privacy at the moment, but I will need block out curtains. I would also like to do eyelet curtains as they take up less fabric and space. So my questions are...... what height to place the curtains- at the ceiling or about 15cm above the window trim, and should I try to find a curtain rod that curves at the ends so the curtains can sit on the walls when they are open?

thank you
