Catalina has beautiful rugs but they are pricey because of their high quality and knot count. However, you can find good and long-lasting hand-knotted rugs at more affordable prices that will still look great and last for years on esalerugs, overstock.com and ebay. A larger rug will have a huge impact on the appearance of your living room, more than a small but finer rug. I recently purchased this one on ebay for a very reasonable price. Because of the large, simple tribal design the knot count is not that high, but if you buy another Persian-type rug it will be denser and I think you'll be satisfied with the quality. In my mind, when it comes to rugs go big or go home.

It's a West Elm Torres rug: West Elm

Another fan of the poly rugs. We bought our first ones when the kids were little and we had huge dogs and put them in the foyer, laundry room and front hall. Those things lasted for years until we got a puppy who decided that the carpet fringe was delicious and then went on to chew the rugs. We replaced them with newer ones and when we moved gave them to the kids - they must be 20 years old by now. We bought them at Macy's, Orvis and even the big box stores. I love the look of jute and sisal but would never buy them, they do absorb dirt, crumbs and liquid and some are not comfortable when bare foot. So if you find some please report back.

I like deeper colors for this room. You have great lighting.. https://www.rugsusa.com/rugsusa/rugs/rugs-usa-iris-fading-oriental-medallion/Navy/200KKCB26A-P.html As mentioned, look for art you love. It does not have to match anything. Go for something interesting to look at, not wall filler.
