The one element I have been using in homes non-stop the past couple years (no matter the style of decor) have been antique Persian or Oushak rugs. There is little else that can really ground a room and make it feel more sophisticated, warm and lived in than a rug with patina. I especially love the look of these layered over wool or jute/sisal rugs (which also can make them a bit more affordable as you can buy a smaller rug and still have the impact!)

In my own home I have one of these types of rugs in my kitchen and I adore how it warms up the space!
Heriz style rugs add a jolt of bolder color and are an awesome option for dark rooms that need a little life, like below.

Entryways are another place to use these beauties (kind of dying over this neutral one below).

Bathrooms are another place they look amazing, again, adding warmth and patina to a room full of hard surfaces.
If you have ever searched “vintage Oushak” or “faded Persian” on Etsy you have probably come across the insanely beautiful selection from Old New House. They have the most incredible stock of these styles of rugs I have seen just about anywhere (like, look at this coral masterpiece??? INSANE!)
