Looking at the Innocent site today I noticed they're asking people to knit some of those little hats which were being sold on the top of their large bottles of Smoothie last year.

If you email thebigknit@innocentdrinks.co.uk and tell them you're getting a small group of people together to knit some hats then they'll send you a special pack to help you organise something.

Each bottle with hat sold will gain Help The Aged 50p courtesy of Sainsbury's and Innocent.

I've applied for my pack and will be knitting a couple of hats (well, I call it knitting and I'm not sure Innocent will want to use my holey creations!) - Innocent are pretty good when it comes to freebies so it's worth applying for even though the contents are a mystery and it could even be just an envelope of bumph.
