Beautiful space. Do you get lots of light in from that window? The cabinets are dark and I think natural light would be wonderful so keep the coverings on the light side, not the heavy rich stuff of the early 90s. A window shade or curtain should have a bit of space. If you are buying something from Smith Nobel, JCP, Macy's or some such place they will have specific instructions for mounting. I do not believe it will rub the paint off. There will be a bit of damage to the walls as screws into the wall will need to be puttied when you take down curtains later. My favorite place for window covering is Calico corners... Have you visited a shop? They are so much fun. Here is a link http://www.calicocorners.com/ I like fabric as fabric can really soften a space. Although if you love bamboo or woven shades that can be nice too. Here are some visual ideas...

I'm with Marcolo for all the reasons stated and, because at night with 2 full walls of draperies closed, it will look warm and feel warm, and all that fabric will add softness not only to the look, but the sound of the room as well, making it feel much more cozy. Moreover, the ceiling feels short and the vertical lines from draperies will make it feel taller.

A valance will hide that and will make the room look a lot less like a sun porch and more like a room. The fabric need not be a print, but it could be with colors pulled from the lovely scene outdoors to bring the outdoors in.

From what I'm seeing, drapes blocking some of the view won't hurt as it looks like on one side, it would block more of the deck than anything else.

Hey There: My suggestion for your windows are motorized roller shades. I believe you don't have power to the windows, so a lithium battery operating system (the charge lasts 6 to 9 months) with a remote control is a great solution. Minimalistic style to keep the openness of your windows. You will cover only the squared part of the upper windows though - the roller shades will line up with your horizontal bars in the window. The different height in the window give a nice variation in design. The roller shades are only 2 1/4 and not bulky - no casing is required and you can operate them from your smartphone. To charge the roller shades, just plug them in like your tablets and recharge them over nite - done. (no chain though)

I love solar shades for this purpose you get heat and UV control and get to keep the view great for daytime privacy not for nighttime so if that is important I just do simple drapes for that.
