Many of the people selling linocuts (or whatever) will have been to art school or at least had some significant training. And they will have spent years doing nothing but art. A hobbyist, especially one who isn't trying to make a career out of it, isn't going to be able to compete with that. Which is fair enough. Why would you, as a hobbyist, expect to compete with full-time professionals? But it's also true creative markets are a bell curve. The big money is in the mediocre middle. It's why a novel series like Twilight or Fifty Shades of Grey sells in dumper truck quantities, while something more adventurous and original probably won't even be picked up. Most people are mediocre at what they do (by definition) but it's still possible to be financially successful, especially in a middle class career. If you want mass praise and attention, that's a different problem.
