IMO the darker drape does not work with the sofa. As for snarkey I will say that to have blinds to keep out the sun is the worst choice I like to be able to see out of my windows so I choose solar shades to control light and heat they also give you day time privacy and then I add drapes for nightime privacy . As for what to se for drapes I would need to see the whole space and no matter what you choose make sure they are the proper length

Plantation Shutters would be a great option on those windows. Determining inside vs. outside mount is going to be based upon multiple factors: Do you window tilt in? Do you have enough depth for the panels to mount? Do you have enough depth for the louvers to open? These are all kinds a professional shutter company can determine if you have someone out for an estimate. Most of the stuff we do these days is outside mount because of tilt in windows or lack of depth in the opening.

The best shades for casement windows are bottom up top down minimalistic shades. They host inside mount to your casement trim and allow for free adjustment to any position of your window. Visit us online at www.fenstermann.com or give us a call for a free video consultation at 619.665.9446

Since you have the cranks on the windows and need access to them, I wouldn't put anything there. Valances can be old fashioned and your windows are more contemporary. If I didn't need privacy, I would forego window treatments. The views are nice, but if you don't want to see the deck and its furnishings, try an inside mounted semi-sheer cafe curtain on the tall window. That still allows a view of the trees, but will block the deck and railings from sight. Add color to the kitchen with some colorful hand towels, pot holders, crocks/cookie jars/canisters, a kettle or small appliance. If you limit the items to a few decorative accessories, you can change them out when you feel the mood or the seasons change. Pops of orange A bit of lemon Turquoise
