Recently came across the Freecycle group - http://www.Freecycle.org/
- on a yarn hunt.
It's a system that started in Arizona in 2003, where people who want something but don't want to pay for it or have something they can't get rid of but don't want to throw away can meet up and recycle things.
I had a look on my local groups' ads and have already acquired 6 pairs of needles and a bag of wool for free. You never know what you might find, one mans trash is another knitter's treasure! Just thought I'd pass on the word
