Hmm...actually, that does give me some ideas. I am thinking of either some kind of crazy alien world like imagining creatures from another planet. Either that or underwater. Or perhaps it could be covered in images from classic movies...old Hollywood style or something. (Do I have ideas? Haha.) No, I have never done a wall mural. But it is something I have thought about doing. We have textured walls, so I haven't tried my own, either.
Yellow, orange and gray/green works, too.
