An interesting look at how Ghostly Ferns has built a 25 person strong design firm where no one is actually employed by the company:

Each Ghostly Ferns team member is simply a contractor that I work with…A team of individuals who can work when they want on their desired number of Ghostly Ferns projects. This allows them ample time to work on their own personal projects and clients. Thus, a non-employee design studio is formed. Everyone loves the freedom of a freelancer’s life with the stability of regular clients.
