Allow your child to personalize his room in ways that are important to him. Make sure to praise your child on his or her design choices. Consider making decorating the bedroom an ongoing family project with little touches added every so often. Your child might also surprise you with great ideas. Wallpaper borders are an easy way to give your child's room an instant sense of style.
Borders are fun, simple to install, and they give the room a customized look.
The design choices are plentiful, and when your child outgrows a specific pattern, you can easily replace it with one more suited to his age. You can do a lot of mixing and matching. For example, you can get your child a character-based or patterned comforter set, yet rotate solid color sheets that coordinate with the design theme. Don't feel that your only options for children's rooms are juvenile products featuring the popular character of the moment. You could just go with various color combinations instead.
