Focus, Focus, Focus

I was browsing Elle Decor's Danish site when I came across the fabulous fabrics of Dedar. A google search led me to this image, which was immediately bookmarked under my inspiration tab. The wall covering is Dedar's Brio, but how easy and cool would it be to paint a focal wall in a design similar to this? I think it's very doable and is a top choice for me when I attempt my bedroom redo. Enjoy and be inspired!
