Some times you just need to start over , take it all down and try again , I have some patching to do , but that is very minor.
I have been bothered by this dining room wall arrangement . I have tried and tried to make it pleasing , but I have never really achieved the look I wanted , which is why I think it is good to take what you have and re-arrange , it costs nothing, it's re-design. Here is the before which I have shown before . I was even considering changing the wall colour , but now that I have found a happy arrangement I will not do so , I love the blue and white.
