This stair runner is a neutral stairrunner finish with a monochrome striped border.
The essence of this design is the contrast between natural texture and a linear design. This is a design dream. Maintain the theme by contrasting a clean grey off white wall with a natural colored modern art painting. Marble or stone surfaced lamp table will match well. A simple rafia coloured lamp will add light texture. A statue in hamered steel or stone will be a great fit.
Stay with natural colours. The effect will be a designer high-end finish.
