Sainsbury's put the hats on the smoothie bottles and for each hatted smoothie sold, 50p goes to Age Concern.
Have a look at http://www.innocentdrinks.co.uk/thebigknit/ if you're into knitting, it actually looks quite fun. They have patterns or you can make up your own design. With a target of 400,000 hats for this year that's a LOT of knitting. I'll be looking out my wool bag and needles when it gets dark.
Thinking about it, vegetable themed hats could be fun.
