Break this down into two steps to make it easier. Tackle function first. Don't worry about a valance until after you live with the shade for a while. Get dressed and go to the stores and play with their displays. Find one that give you privacy, but also works with your fan. The valance is just fluff and you might decide that with your clean lines that you don't want one. The pleated shades that Daisy mentioned sounds just like what you need. Even a nice tailored pulldown sounds great with your Shaker-style furniture.

@Melndo The walls are Benjamin Moore Rockport Gray: https://www.benjaminmoore.com/en-us/color-overview/find-your-color/color/HC-105/rockport-gray?color=HC-105 Our window is north facing as well. There is a large Japanese maple near the window so we don't get a ton of light there. I have the floor lamps, two table lamps and a light on the ceiling that isn't in the picture to make sure the room gets enough light. We actually use this room as a music room. There is a piano on the wall that isn't in the picture. Hope this helps! Glad you like it. :)

eld6161.........thanks. I too am in Florida. My second shutter vendor was here yesterday to measure and price, etc. The first told me I would find the slider "cumbersome", the second disagreed....and offered a reg. slider or a bi-fold slider. Did you have that option and did you use a bi-fold design anywhere? I do see where it would allow in more light, balance the visual appearance of the door when both open, but I hadn't even been expecting that option and I am typically NOT a bi-fold fan.....thx for any additional info you can share.

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
