Stacked text sign

I have not had my machine long, about a month or so, and am still using the free version of carbide. That said, this question is just a general one.
I just made a stacked text sign. It came out right and im very excited about it. Like most, i wondered if i could sell a couple. The sign took 3 hours to machine. After checking similar signs on etsy, they sell for about 75 bucks. How do you make any money that way? Are the guys that make a living with this running multiple machines?
Just curious
Thank you

That’s a good question.

I’ve written a bit about this in the past here:

and we now have an official page on it:
