Wow, that's some window! Is it all one, or in segments? If it is in segments, you could use interior mount blinds on each one. Normally, one can put long panels even on a shorter window, but without seeing a photo, can't be certain.

Go to Houzz photo section and type in key words for both large and wide window treatments. Lots of ideas. Also 3 day blinds and Budget blinds will come out and measure and bring samples and ideas. They do curtains and valances etc also.
My suggestion is to keep it simple. Fussy and elaborate swags etc get dated quickly. Let the window be the star.

Thank you!

The window is in two segments. There are woods outside, so even though the window is large, the amount of light coming isn't great. I am thinking sheers for semi-privacy and to leave more light in and then, short to medium drapes for design.
