knitting for charity

I have just read that Solving Kids' Cancer charity are looking for knitters to knit butterflies. They are needed for a Butterfly Relay in May where people are going to walk, swim, cycle and run 21,000km to raise funds for children suffering from cancer. You can download the pattern from www.solvingkidcancer.org.uk/Event/butterflyrelay. Just thought it would be a good way to use up your odds and ends.
