When I first started to knit and crochet for charity, I wasnt sure where to get started. I was rather lost, in fact. So after I got a grip on things I started a group for people to share resources, links, stories, and pictures. We don't have any particular charities we donate to as a group, but if you need help getting started feel free to ask.
The need is GREAT. And each person can help.
The groups location is: http://groups.yahoo.com/group/CharityKnittingandCrochet
Feel free to join and chat, and make sure to check out the links and files. And if you have anything to add to those, feel free to do that too.
