We used 4 runner rugs I found at Wal-Mart. (The pattern was perfect to go with our theme in our home.) Attached rug padding underneath runners before install rugs. As we staple gunned rugs down we cut each rug to fit together where the tread meets the riser. When finished you can't even tell where each rug meets up. We still have some wood trim to add before this home DIY project is comeplete. Will add additional photos when done.
