For a collection shelf of miniature race cars, for example, your child might want a backdrop of pictures of real NASCAR drivers. A box for keeping special pen pal letters could be covered with cool stamps. Or an old step stool might take on new life when covered with a hodgepodge of your child's favorite things: Shetland ponies, gerbera daisies, baseballs and Amazon parrots. If the artwork is very thick--or, conversely, so thin the words from the other side show through--try color-copying it first.

To apply the images, first clean your surface, then paint on a thin film of decoupage medium. We especially recommend Golden Soft Gel Matte medium, a product available at craft stores that won't yellow or crack over the years. Apply the art and let it dry for five minutes. Paint a thin film of gel over the artwork.

CRAFTER'S TIP: For surfaces that will see lots of traffic (say, a step stool), add a layer of clear varnish for a durable finish.
