First things first: There’s a reason wool is such an industry standard when it comes to durable, soft and show-stopping rugs you can place in your home. For one thing, it’s about the construction—many wool rugs are handmade, which means they can cost a bit more, but they are practically stain-proof and, with proper care, they’re designed to last for decades.
So, how do you determine if the one you’re purchasing is high-quality? In other words, shedding happens with wool—it’s a natural characteristic of this type of fiber—but this attribute should be temporary, a detail that comes down to the quality and construction of the rug you choose to invest in.
Per Adams, you first want to check the actual makeup of the rug. “I would suggest searching for a rug where the primary content is wool—meaning the label should indicate that its wool makeup is 50 percent or higher,” she says. “There are many fiber-blend rugs out there, which is where you can start to encounter an issue. That’s why you want to double-check the content of the rug before purchasing.” If a wool rug is mixed with other fibers, that’s OK, but only as long as the wool fibers make up the majority. (For example, the Masinissa rug from Annie Selke is 92 percent wool, 6 percent cotton, 2 percent polyester.)
There’s another way to check for quality, according to Adams. It’s called the “dimensional stability” test of a rug. In other words, you want to check the stretch. “Quality handwoven wool rugs are woven tightly and over little to no stretch when you tug on them. A rug with a lesser quality will be woven loosely and will often stretch easily or become misshapen over time.” (Reader, see photos above, but my 5+ year old rug is an immediate fail on this test—totally misshapen and in need of constant adjustment; in comparison to the Malta blue handwoven wool rug, which is 92 percent wool, you can immediately see the higher knot density.) Adams adds that, a high-quality wool rug will generally feature 20+ knots per square-inch, a detail you can check just by looking at the back.
