Perhaps the most noticeable sign of sub-par quality in a rug is shedding. Even though it’s normal for a new Oriental rug to shed a small amount during the first few months, this shedding should be a cause for concern if it’s too extensive. A quick and easy way to detect low-quality wool is by using the agitation test. First, thoroughly vacuum the face of the rug. Next, agitate the wool several times by combing it back and forth with your hand.
