Add a contemporary appeal to your home by complementing the interior design of the room with a cowhide rug. Large cowhide rugs span approximately 30 to square feet, and the beautiful cowhide adds a different character and flair to the room. High quality cowhide rugs can easily become heirlooms, which is why it's important to spend some time inspecting the quality of the rugs before buying them. In particular, you want to watch out for an unwanted effect known as cigaring.
