Don't know if you have an IKEA around, but if you do, check out their cushion covers (I think you can also order on line for many of them). They have some amazing choices for a very reasonable price, and their feather pillow stuffers are terrific, again at a good price (they are not down, but fowl feathers, and are a great deal - I have a ton of them). The Alvine Lov pillow is wonderful, all embroidered, and a good size for your couches. I have two of those - shades of yellow, green and a blue-grey. The Urusula could be a perfect neutral for in there, and is 26x26, so a good corner pillow, with something more colorful in front of that if you like. I also like the Benzy Land.

UPDATE I just received this Fornasetti pillow from Etsy -- it's an outdoor pillow and I intended for use on our deck. However, I kind of like it in my office. What do you think? Perhaps it can live here during the off season.

I love a bright, clear accent color for pillows and lamps. You could do a teal, a yellow, a royal blue, a grassy green. I would go with almost a mid century style lamp and tailored looking pillows with a combination of textures and patterns. https://www.houzz.com/products/2-tone-matte-and-gloss-teal-blue-ceramic-table-lamp-prvw-vr~119612892 https://www.houzz.com/products/pillow-18x18-turquoise-feathered-velvet-prvw-vr~122115714 https://www.houzz.com/products/tizia-knife-edge-pillow-indigo-teal-prvw-vr~37450220

Thank you BAC717! The rug is probably my most favorite item in this room and honestly I never would have even purchased it if it were not for the help of my fellow Houzzers. I do not have a good eye for decorating, and these guys have really helped me see the possibilities. We've been in our house for 7 years and this room has always been a struggle. it just seemed gloomy and blah! To me, the room has so much more character now and it's more "me". My 2 posters came in the mail this week. I'm going try to get them framed and hung this weekend. We are still undecided on a paint color. Someone recommended BM Natural cream, which I like; however, because I want to use the same color throughout the entire first level, I have to make sure the wall color works with the kitchen cabinet color (BM Dove White), which has grey undertones. I'll check out the color you recommended also. I have a bunch of paint sample cards but no real contenders yet. Good luck with your room. Let me know when you post and I'll check it out.
