CALLING ALL young artists: Weekend's holiday Wrapping Paper Contest is back. Enter our seventh competition and you may get your picture on the cover of Weekend and your artwork printed inside. Or you might win a Washington Post 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. 20. 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 Weekend 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 Harry Potter and friends around a Christmas tree.)

* The finished design will be 12-by-21 inches in size. You may make your drawing that size or in that same proportion -- about 1 to 1.7.

* 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, your age, your telephone number and your address.

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

Entries must be postmarked by Nov. 30. We'll contact the winner by Dec. 6.

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