Trend Enabler

Wallpaper companies are creating exciting new products -- from die-cut borders with scalloped edges to papers that feature tactile patterns and iridescent colors. And with every technological advancement, wallpaper gets easier to apply and remove. Decorative paint treatments have a similar ability to transform a room with color and pattern, and they now involve techniques almost anyone can attempt. No matter what you choose to cover your walls, you can keep up with every decorating trend that comes along without batting an eye.

This bedroom looks inviting with its crisp white embroidered sheets and bright apple-green blanket. But the room's multicolor elements -- bedding, miniature chairs, containers, rug, and lampshade -- have a disconnected look.

Just look what happens when the walls are covered with colorful striped wallpaper. Suddenly, it's a stylish, cohesive room, where all the colorful elements are knit together.

• If the prospect of committing to wallpaper still makes you a little nervous, consider consulting an interior designer to pick out a wall covering that works best with all your furnishings.
• When it comes to hanging wallpaper, you can hire a professional or try it yourself. Pre-pasted papers with limited patterns and small repeats are fairly easy for a beginner to work with. If your room has lots of architectural features, such as doors and windows, to work around, you may want a professional's skills.
