"Regardless of a child's age, one super-quick and easy way to change a room is to add art to the walls," says Jennifer Condon, an editor at Domino magazine, which is compiling a special frugal-decorating issue for August.

Here are a few simple and inexpensive ways to dress up a youngster's space:

Old books. Amy Clark, owner and founder of Momadvice.com, collects art from the book jackets and pages of her children's favorite storybooks.

For tweens and teens, choose books based on hobbies - dancing, sports or other passions. Garage sales and thrift stores are excellent sources for affordable books.

Display accessories. Place colorful plastic hooks at eye level for young children and encourage them to hang up party clothes, costumes and hats, which then become colorful wall hangings.

Likewise, hair bows, ribbons and barrettes can be displayed on easy-access cords, Clark says.

Contain clutter. Attractive baskets and bins can be stored under beds, on shelves, or in wall units.

Condon recommends brightly covered woven baskets from the Container Store. These baskets have tags for handwritten labels. "It looks chic, but it's still very kid-friendly," she says.

Use paint. Color can add bright accents to a room. For instance, paint a large square behind your child's bed to create an instant headboard, Condon says.

Calendars and cards. Recycle old calendars by framing photographs and images from past years.

Flash cards - ABCs, math problems and vocabulary cards - can be mounted to create borders around a room, Condon says.
