Paint the walls your chosen shade of light blue. Pair the light blue with an elegant white molding that works with any style you choose to create in your freshly painted space. You can also paint a fourth wall in a blue and white stripe or even add blue and white wallpaper. If you're seeking a contemporary look, opt for the blue and white stripe. Create cottage chic through a floral wallpaper, and keep it romantic with a simple blue and white fleur-de-lis.
Place a simple white set of linens on your bed. These linens are an ideal base regardless of your personal style. If you're opting for a more contemporary style, toss an assortment of blue and white pillows in geometric patterns and abstract prints on the bed. A cottage chic space can be created through an assortment of light florals on the bed, while a romantic look can be created through lacy white pillows.
Add white side tables to your room. Silver candlesticks and a blue and white lamp set can be added to your side tables. These items work regardless of the overall style and most important, work with your light blue walls.
