JMittman Designs I've participated in many a tweechat on Twitter. They are fast, dynamic, and last only one hour. I am picturing 982 opinions without time for any resolution or discussion!

Aegean-Designing Whims First, I love your kitchen, and I'd also consider not using any window treatment and doing another room that really needs a treatment.
My second opinion would be to use a Hunter Douglas roller shade which would compliment your style.
As far as having the whole house to do, I'd do one room at a time and do exactly what you really want. Sometimes when you skimp or don't do what your heart tells you, you're sorry, and end up living with something you don't love.
Have someone measure your windows and help you with selections, then do a little at a time. Classic design always and having the right treatment always wins in the end.

Delfina P.S. honeycomb not recommend because you have a faucet right above the window and they will get wet and dirty, I have this problem with my plantations but at least those I can wipe easily since they are wood.

ASVInteriors If it is the sun that bothers you, I definitely vote for matchstick blinds. You can still have some view outside (or even roll them up when not required) and they do a great job of blocking harsh sunlight but still allowing light in

Aegean-Designing Whims Depending on the style of furniture you're going to be using, I'd consider using woven woods in a lighter color with stationary drapery side panels. I'd only treat the bottom portion of the winddow and leave the arch.

For a softer look, look at Hunter Douglas Silhouettes, or Pirouettes too

White shutters would also look good in the room, but again, I'd like to know more about your decorating style.

leelee27 Doxa: Is it a no- no to do fabric blinds and drapes in the same room?

Visual Senses Design Naturally all depends on the interior decor and the amount of sunlight you receive there and how much you want to let in or not and how often these windows will be physically opened. You could use Fan shaped blinds example http://allaboutwindowscolorado.com/aaw_march_2013014005.jpg
Classics but nothing to write home about. If so much work goes into your new home already I would hold on to something that creates a showcase yet is practical and makes a statement.
If this is something you can agree to and you want to go somewhat truly creative DIY (or have it done) you could attach tiny rings all along the above clock curve 9 to 3 say every hour and then attach lined banners that start from each point going down and getting wider and wider. You want their total width be say at least 1 1/2 of the total window if not double so the banners when open will fill the entire window and slightly overlap the total width including the window frames. The top departure points can be pointed, horizontal, triangular, square or also 1/2 circle but always in proportion with the 1/2 circle. They also could be crush balls ( very affordable) from IKEA. It's like a spiral you twist and turn your fabric in and then let it fall. So you could get a very effective pom-pom effect that frames the top.That could even be a contrast colour or glam it up with a metallic. Say 5-10% of the total length of each banner that will remain in that constant pom-pom position and create a 1/2 contrast circle framing it from Gold, Silver, bronze copper what ever fits the entire concept.
This is NOT exactly what I have in mind but it somewhat is on the way to my concept. Instead of one drape it is multiple vertical banners. http://interiorway.com/wp-content/uploads/2013/04/Traditional-bedroom-furniture.jpg
They then could drawn back contrary to what most decorators would do into one center bunch.
Depending on the height of your drawback ring that could be placed exact at the height of the cross window section (make that a creative one say a horizontal half "8" could create "tree or flower bouquet " effect of any type. Flowers, geometric, graphic lines, or Dobby/Jacquard relief woven lines in mat and shiny satin or other or colour contrasts or simply plane and simple. If you are more of the romantic type you could have a center bow to actually tie or have one bought or made in Iron, Resin etc..
The effect will result of an impression of height and column type of support while
Again depending on you wishing to have them resting on the floor when open or closed you can define the bottom shape and length. I personally would let it rest on the floor when tied back. The ends of each banner could be 1/2 circle petal shaped. Sorry on my pad now on transport can't draw here but would be gladly to send a you sketch if you contact me through my website. www.visualsenses.com All the best.
