We all have hobbies, but few of us are lucky enough to be able to earn a living doing the thing that we love.
Nonetheless, it is more than possible to turn your hobby into a viable business. Doing this is a great idea, for a number of reasons. You are likely already spending significant amounts of time on your hobby, and so you might as well make a bit of extra cash whilst doing it. In the best case scenario, of course, it is possible to make a lot more than that.
