Do you have a rug or are you getting one? I will tell you whatever you decide for drapes they need to be double the panels you show there. I would also look at a lamp with a white drumshade the lamp you have is too small and you need the light to shine down .

no rug, i tried grey curtains, but that did not work against the sofa. it has slightly turquois tint to it and grey looked purple with the sky outside. thanks for the size tip!

WHITE LACE would also look pretty but depends on your decorating style.

No lace curtains with that sofa and IMO white drapes very often look like sheets on the window.That is why I suggest a print not to fancy but it works when one color just doesn't
