You can buy wallpaper that makes an actual scene to look at rather than repeat patterns although they are not cheap. Otherwise a huge poster or maybe a wall hanging/rug or a folding screen?
thanks Prudie for suggestion - I really need to see what I have said - 4-5" wide by 12" long. That is the space exactly. I was sorta contemplating like a beautiful long mirror effect. It's difficult to explain.
Mamy - that is what is on the wall now but not pictures etc, just like tiny pieces of material down the wall inside a wooden frame (not that nice). But that is generally what I would like but sparkly. Thanks for looking everybody.
