Stella McCartney donates sketch to auction

London: Former Beatle Paul McCartney`s daughter, designer Stella McCartney has donated a signed sketch to a charity art auction, which will benefit children with special needs.

The auction will also feature works by painter David Hockney, Damien Hirst, art collector Gavin Turk and 22 other contemporary artists, reports

"The art auction is the main fund raising event of the year and this year is extra special," quoted the charity`s founder Jo Manuel as saying.

Although Stella is not an official patron of the Special Yoga Centre, which specialises in providing yoga therapy and other support for children with cerebral palsy, down`s syndrome and epilepsy, she helps out in other ways, and has supplied the children attending the centre with clothes for the past several years.

Honorary patrons of the charity include British Prime Minster David Cameron`s wife Samantha Cameron and actress Trudie Styler.
