I love the idea of accent walls. Sometimes you need one to add interest to a certain area. Sometimes we use them to anchor a certain peice of furniture like a bed or a large dresser. But sometimes we use them because we just want a little spice in our life.
Have you ever found an absolutely amazing wallpaper, but it was just too busy to cover a whole room in?
Or maybe you have fallen in love with a certain paint color, like lime green or sun-flower yellow, but you think it might make you go crazy if you painted your whole living room that color?
Well what about using your ceiling as the accent wall? That way the whole room gets a touch of the pattern or color you love (not just one area) but the space doesn't feel overwhelming.
My grandmother had a room with a wallpapered ceiling when we were growing up. The ceiling had this huge sunflower pattern on it. The room was so beautiful and so interesting. I cant wait to wallpaper a ceiling in my own house one of these days.
