John's post above is extremely important in my opinion.
Be careful what you wish for...because you just might get it.
I have ruined a few hobbies in the past by getting too serious about them and/or by trying to make serious money while doing it. Photography is the first one that comes to mind. I used to live, eat, sleep, and breath photography. After I did it for money for a while, I began to hate it. The only pictures I take now are of baits and fishing trips.
Jed's point is also one that should be given a lot of consideration. There is competition from "mass production builders" out there. You are simply NOT going to compete with machines that can more or less automatically crank out a bait every 4 or 5 minutes or so. If that is not enough, much of the mass production of baits is done overseas where the cost of labor is unbelievably cheap.
I do sell a few and like Jed, I use the funds to finance my bait-building addiction, nothing more. My 'market' is guys who want a truly custom, one-of-a-kind, hand-made fishing lure. I do not try to compete with the businesses who make a $12 musky lure. My primary goal is to have some fun with all of this and make a few friends along the way.
Can you "make a living?" Jed once told me, "You'd probably make more money delivering pizzas."
I think that is still true for a "basement builder."
