You have a great looking home! The kitchen is fab and I love the contemporary style. As far as curtains, since you pretty much have no color or pattern in the space(s), I'd suggest a curtain with a pattern in an accent color of your choice. What color(s) do you lean to?

Since it looks like "color" is out of your comfort zone, you could do a gray with pattern? But, I'd prefer a pattern with some color, the add pillows and accents accordingly...

I just modified some sheers I added to the black out curtains we have in the master bedroom. I added 4" strips of felt then put a wide ribbon along the top edge. It dresses up the curtains beautifully and added the length I wanted to see. Will post a picture tomorrow.

Still finishing them.....here is an in progress shot that shows the bottom. The black out curtains are similarly dark grey.

Also your curtain rod behind the sofa may need to be straightened, it looks a bit higher on the left. You may want to pull your sofa away from the window a bit and bring the other one in closer to your coffee table as well. Very nice home!

We recently renovated and used this site to get some ideas for decor because we had everything neutral too. I added you to collaborate for our living room/dining room idea book because when I took the advice given and added the colours and accents, we couldn't believe the difference. Have a look and see what I mean.

Aww thank you .... believe it or not that flooring is actually laminate and was pretty easy to install. I love this site I had no clue where to begin or even what colour to use. It has been a great adventure pulling it all together! Good luck in your design project.

I love the gray scribbles drape from West Elm. Gives you pattern, and then you can add color in art and accessories. Good luck!

Your rod is not too high; it's just right. Your curtains are too short. In such a neutral room, you can do any color and/or pattern you like.

If you're afraid of color, try texture instead. Linen or burlap might be good choices.

Your rods are mounted at the correct height(just should be straight, like you said.) In general, rods should be installed higher and wider than the window frame. Installing the rod to accommodate the length of the pre-made panel is not good design. Whether the panel hits the floor slightly or hangs an inch above is purely subjective.

Hopefully these design solutions will make you a little more brave.. We focus on the some of the parts not the individual fabrics.

How about a rich navy velvet http://www.houzz.com/projects/879651/a-bold-masculine-den-makeover?

Our design team can make some suggestions. Ask a free question here http://www.decorist.com/questions/ . Also note that hanging them just right makes them look more luxurious. These are West Elm.

Yes, you do not need to buy new drapes. Just buy additional fabric for adding to what you have. Same fabric different color. It looks like you need an additional panel on each side though. I love the Greek key trim idea. Go with more than you actually are short. You will need to have a larger piece to add on. Take down the sheers. Use a white with the Greek key design & have them professionally done. Go gray, Greek key strip, white section, then end up with gray on the bottom. Kiss the floor. Fix your rod. Have some pillows made with same gray, white with Greek key (smaller) design for your sofa. Add large abstract art. Be brave. Go for it.

Buy a larger area rug. Pull the sofas to put front feet onto the area rug. Go with a white and black wide stripe pattern for rug.

Little by little add some color. one color in threes.

Hey there.Your space in amazing. I think it may worth the investment to consider custom window treatments. This will allow you to achieve that correct height and weight of each panel.I have a few blog posts that may help you out.

Couple of questions first, can you return the drapes you currently have? If you can, I would do so. You need the 108 inch length and they're difficult to find. I also suggest you look at the extra wide, 100 inch wide panel, thats a fairly wide window you have. I ordered mine on Amazon. I ordered "Best Home Fashion, Blackout" great price, excellent quality, great reviews, and in many colors. You will find many reviews said these are better quality than custom draperies they have had made in the past, for a fraction of the price. The rod is in the right place, dont move it, just check it for level. If you can't return them, do you sew? I would sew or have someone sew a darker band of fabric along the bottom. Having someone sew a new header will be very expensive.

Maybe an orange-red, or a color from 2nd throw:

Maybe sew 'stripe' near or at bottom/ or at top, sort of modern look.

The gray color of the current drapes is also a bit off...looks like you're trying to match and missed slightly. Go for a different color or texture as others have suggested.

I think you should get the drapes with the most color and design you can stand. They are easy to change out. I also agree to get 108 length drapes. The rods are fine where they are.

Here's how they turned out....
