I've been around here long enough to know "they" are going to tell you your tv is too high. I know this is not what you asked but can you rearrange your couches so they are in an L and put the tv on the wall? I think picking out a rug so you can go off those colors would be a first step.

Yes I am going to lower my TV down. Someone told me to select curtains first and then large rug. So I was little confused

yes, i agree with the L shape, have one couch face the fireplace and one face the tv on wall where sofa is now.

you have pale green couches, what other colors did you want. and i too would go with the rug first. I saw a parisian glam which was pale green, pale pink and cream? i will give you a few rugs.

I love pale green and blue! And your instinct toward having patterned curtains is exactly right to my way of thinking. I would, however immediately eliminate your second and third possible curtains. Those large "chain" prints are very tired and over used. Focus on block prints and smaller scale patterns (I particularly like block prints myself- if you like that look try Etsy.)

I would look for a blue background oriental rug and add green and blue throw pillows on the sofas.

I love the top one.

I happened to notice your dining room rug and I'm sorry to say it's much too small. The rug should be large enough so that you when you stand up and pull the chairs back the chairs are still on the rug. This will also give more emphasis to this area as a room instead of just a small space. I would wait, however, until you've chosen your living room rug so that the two rugs will be complementary in color and style. The size of the living room rug, by the way, should also have a very generous size. I would personally choose plain white or cream colored curtains, or curtains with a subtle pattern and color if your carpet and pillows are colorful and you put wall art in this room (which it needs). With the darker patterned curtains your eyes will go straight toward the windows, whereas the attention should be directed to the room itself.

Having recently purchased a rug and drapes, I agree with Ingrid. Get the rugs first. Much easier to pick drapes afterwards.

Here are a few more rug ideas.
