there is nothing secret about “A master Craftsman” the only thing is there are very few about these days.
Sam Maloof comes to mind and the Roesnberg Family ( I think that is how it is spelt)
To become a master craftsman (IMO) you would need a very enviable ability to think outside the box, believe in yourself, be highly motivated and then posses the skills to produce your thoughts into 3D and then have an ongoing market for them.
So now you know!……so are you one ? ……I for one know I am not.
