The Persian Empire Wool Stair Runner Collection is the latest in new updated colors and patterns from Nourison. Our customer had a very busy wallpaper removed and decided to paint a strong shade of grey on the wall. The wool stair runner added some pattern to the staircase. Great choice on her part. The custom installation required two pie shapes, 2 end caps on the first and last riser and the installation of the stair runner using the hollywood method.
