Did you know that Julia Roberts knits? She's been quoted as saying:
"I sit on the set and knit. It's a very social hobby, as opposed to reading at work - I can chat with people and still be fully engaged."
Tom Hanks, co-star and director of "Larry Crowne" - which, BTW, I want to see - along with some burly chaps in the crew, played a practical joke on Julia. Take a look.
As she says - "all you need for knitting is a girlfriend to get you started!"
