Here is a link to the room. Ignore theh brown curtain on the tension rod. DH hates it.

Hi Laura, the colors in the photo must be off since the walls look brown and beige to me. Do you have a different color behind the entertainment center? The wall behind it is confusing too. Is it the lighting from when you took the picture? Either way I guess a beige window treatment would work.
That art on the wall sure looks pretty.

The Hunter-Douglas Silhouette is now available in top down/bottom up. The window casing you have is deep and the shades could be inside mount and look good. Silhouettes have very big headers.

I would go with a color drape the same tone as the walls but darker. The walls look rather blueish in the photo - maybe due to not using a flash?

Some heavy, polyester silk-look would make the area elegant.

These come in various colors.

I would do the top down-bottom up blinds in a wood or bamboo to blend with the wood trim on the window.

I don't like a lot of contrast between a wall color and drapes, so I would look for a green and white stripe with the green in a similar tone to the wall color. I like the poly-silk idea above, but keep it plain and simple since the furniture is casual/rustic, except for the piano.
