Decorating a large space can be overwhelming and finding the right balance of furniture and accents on the wall I find to be the trickiest part.  Those things plus a lack of knowing what my ‘style’ is caused us to live in our house for over a year before anything major was put onto the walls.  In my defence we were coming from a very small apartment so what works in 500 sq ft doesn’t always translate well to 1500 sq ft.
