This was Lonni's final project on Design Star, and it's kind of shame that she was sent home over this room. It is absolutely gorgeous, and the printed grasscloth wallpaper is pretty much the whole reason I love this room.
I love the light and airy colors and patterns of this accent wall. It's subtle and sweet, and not "in your face", which creates a more sophisticated look. And I like how it meshes with the striped material on the chairs.
I think this is kind of a neat idea if it actually looks this good in real life...placemats hung symmetrically to mimic wallpaper...but for a fraction of the cost. It photographs well, but I just don't know how well it would translate.
This next picture just makes me happy. It is my favorite accent wall on this post.
But if the wallpaper is too expensive for that look, try stenciling it on with chalk first, then painting over the chalk.
This may not fool you into thinking it's wallpaper, but the painted stripes add so much to an otherwise less exciting room. See before and afters here.
I can't really think of a place in my house that would be appropriate for an accent wall, but I love looking at other people's creations!
