Before you hang the rod, consider whether you want the curtains to fully reveal the window when open or partially block the window ... and capping the ends with finials if you so choose.

Not only does a standard curtain-and-rod setup partially block corner windows ... but they may still end up getting caught on the middle bracket, making for clunky movement and frustration.

A good curtain rod will be versatile, both in terms of function and aesthetics: Ideally, you’ll change them out less often than your curtains, so you want them to work with a range of styles.
