Your teen's bedroom is her personal space, which should reflect her personal style and tastes. Adding decorative accents to the walls of a teen's bedroom not only adds visual interest to the space, but it enables her to showcase her personality. You can help your teen highlight things that suit her taste and are important to her with the help of wall shelves and other accessories. Here are some tips for decorating your teen's bedroom walls.

Frame pictures and posters and display them on the wall, creating a collage effect. Ask your teen to choose painted pictures that she likes, or photographs of people and places that are important to her. Have her select posters of her favorite movies and celebrities to frame. Choose frames that match the color scheme or overall design of the room. For example, choose silver frames in a modern room or wood frames in a rustic room. You can either hang the picture frames or place them on wall mounted shelves to display them.
        
A popular idea is to install wall shelves on the wall. Choose wall shelves in a range of sizes and in finishes that correspond with the look of the room. Hang wall mounted shelves in an even line or arrange them so that they are at alternating heights along the wall. You can also ask your teen to select items that mean a lot to her. For example, display her awards, mementos, collectibles and pictures. Your teen can also use wall mounted shelves to store books and sports equipment.

Display theme-related items on the wall. If your teen's bedroom is designed around a specific theme, choose elements that correspond with the theme to feature on the wall. For example, if your teen has a beach-themed bedroom, hang pieces of driftwood, shells, starfish, oars and images of the beach on the wall. In a music-themed room, hang album covers, old LPs and musical instruments on the wall.
        
Feature a mural on the wall. Hand paint a mural, use stencils or hang decals on the wall to create a mural effect. Create a mural that ties into the theme of the room or reminds your teen of her favorite holiday destination. For example, wooded trees tie into a forest-themed room, while images of rolling hills create a Tuscan-look in the room.
