I like hardware like this platinum finish - notice that is won't compete with wood tones on the floor or furniture.
In a large room with tall ceilings & big moldings, you will want hardware that is substantial
(larger in diameter). See photo below, the 6" finials were needed, since smaller hardware
would've looked too skimpy.

are a nice option
I also love thin iron hardware, when it's high quality, it can be simple and elegant, see below.
|Two short window treatment rods are a nice touch if you don't need|
to open and close the drapes for privacy.
Window treatment hardware can vary from very inexpensive to inexpensive.The big difference - if it's an expandable rod, it will make it a little more difficult to open and close the drapes every day (where the rod telescopes the fabric or rings will "catch" ). Some people say they don't feel that's an issue, others say it bothers them, it's personal preference.
