GARY BARLOW, TULISA CONTOSTAVLOS and girlband THE SATURDAYS designed special limited edition Christmas cards to raise money for charity initiative Sketch Santa.

The stars' festive greetings cards were sold at British retailer Hallmark in a pack of six alongside designs by U.K. TV show hosts Aled Jones and Lorraine Kelly, and British soap star Matthew Wolfenden.

Barlow's design features a sleigh-riding Santa Claus shooting into the night sky with gifts falling behind him, and Contostavlos' depicts a Christmas feast being enjoyed by St. Nick and a reindeer.

The Saturdays opted for a more comedy design - a breakdancing Santa sporting Kanye West-inspired shades on a multi-colored dance floor.

The Sketch Santa campaign is in partnership with Text Santa which aims to raise funds for worthy causes including Marie Curie Cancer Care, Age UK and Carers UK.
