Hi Yakob,
That is a very personal question, I doubt you will get many responses ( I may be wrong). I'm new, so haven't made a nickel yet., When the blind start buying engraving art, I'm hoping to cash in.
Cheers
Don
I earn enough to pay the bills and to just dream about a holiday, but not afford one with my jewellery work. With engraving I earn enough to pay for more engraving tools! Life is good when you enjoy what you do for a living. Irrespective of what you earn.
