Like your space and choice of green. Like the green in the kitchen you referred us to. Looks a little darker or less yellow than one you did with Photoshop? You have the same issue as many of us, for one reason or another we end up trying to blend two disparate styles. The couches say man's room, formal, brown wood to me. Your room, kitchen and fireplace say much lighter in colors , style and spirit! If you try to blend the two you will end up with neither. Your purchases to go with the couches will just add to things pushing you in a direction you don't appear to want to go! I'd suggest you find some sofa covers, or even bed coverlets if you can't get covers to put over the couches. I like the colors in the fireplace. Please tell us more about what styles you like.

Oh I have not even touched the surface of fabrics that are available and beautiful. But, best to qualify further if you are recovering or buying new chairs before we get too excited or caught up in the beauty of the products. I love fabrics and the chemistry and technology that goes into modern day fabrics would astound most people. I'm not even talking about the residential fabrics like the Robert Allen collection I showed you. I'm talking about the fabrics for the hospitality and medical care industry. Now if you are interested in MODERN look fabrics I would send you to Maharam to look at their 20th Century Modern collection. Some of those are the real deal by Eames and Girard. Anyway, when you get further along in your plans then I can give better input.

Sophisticated start. You could go with black and white photography, architectural pieces, art pieces- anything you love on the wall. Then, add pillows in the colors of the art work. If you want to stay more monochromatic, think in terms of textural interest, such as a shag area rug, pillows with seam detailing, etc.
