CALLING ALL young artists: Enter our ninth Holiday Wrapping Paper Contest and you may get your picture on the cover of Weekend and your artwork printed inside. Or you might win a Weekend T-shirt.

We want Washington area kids to design their own holiday gift wrap and send it to us. We'll pick our favorite and print it inside Weekend on Dec. 24 as a sheet of real gift wrap. And on the cover we'll print a photograph of the winning artist with his or her design. We'll also choose finalists, who will receive T-shirts. Here are the rules and guidelines:

* Bold, bright colors and repetitive patterns will probably work best.

* No commercial characters, please. (That means no designs featuring Nemo and friends around a Christmas tree.)

* The finished design will be 12-by-21 inches in size. It's best to make your design as close to that size as you can.

* Please don't use a computer for this contest. Use crayons, paint, pencils, chalk, construction paper cutouts, whatever.

* Don't use store-bought stamping tools. You may make your own stamps out of potatoes or erasers.

The contest is open to children ages 12 and under. One entry per child. No purchase necessary. Employees of The Washington Post or their immediate families are not eligible to enter. On the back of your entry, write your name, age, telephone number and address.

Send your entry to: Weekend Wrapping Paper, The Washington Post, 1150 15th St. NW, Washington, D.C. 20071.

Entries must be postmarked by Nov. 29. We'll contact the winner by Dec. 7.

Sorry, but because of the volume of mail, entries will not be returned.

Last year's winners of the Holiday Wrapping Paper Contest were Allison and Thomas Cuesta of Arlington.
