Rowling writes mini-book for charity

A host of celebrities including Harry Potter author JK Rowling have written books the size of a thumb for charity.

Multi-millionairess writer Rowling's mini-work includes her own drawings of witches' hats. It is to be auctioned to help the homeless and is expected to raise a five-figure sum.

Other stars partaking in the initiative include Madonna and Paul McCartney, who hand-wrote tiny Hey Jude lyrics in his donated book.

Tatler magazine editor Geordie Creig, who co-ordinated the idea, comments: "The response has been fantastic."
