You should research well on how the rugs are actually being made. With all the knots and weaving details at hand, you can plunge into differentiating between a look alike and an actual oriental one.
Be ready to invest time
Rug buying is a time taking activity. And when you first decide to shop, make sure you have all your dimensions at hand while buying a rug. The floor should be 2 3 inches visible from the side of your rug as a basic rule.
Choose the vendor wisely
While buying such a piece of art, make sure you do that from a reputed store, which have been in this business for a long time. They will also be able to guide you well on the types, colors and patterns of rugs available and the ones that will suit your house. Do not go for sellers who have just been set up, or at auctions. There might be a high chance that you might get misguided into buying something fake.
