Starting your own home crafting business.

       A friend of mine recently mentioned she would like to crochet for a living. She is fairly good at it, can make her own patterns  and right now some time to actually do it. I would love to craft for a living too, Lord knows. So where should she start? Any suggestions? Helpful websites? Cheap suppliers of yarn? She still needs a name and a focus but I expect great things from her. She recently made a Jake and Finn.
