Stairways are often a forgotten spot - sure you hang some pictures along the wall, but stairs usually lack style. Try wallpapering the risers or painting the entire stairs with stripes or patterns. It'll make going up and down the stairs a lot more enjoyable!
Black & white bold patterns add drama.
This is a great way to use leftover wallpaper or paint from previous projects. If you're painting your stairs, be sure to use an enamel paint for durability.
