It always amazes me how long ago people were able to do quite complicated tasks.
We take for granted things like cut glass now, although it is still quite expensive.
But, back in the day, it would have been laboriously made with simple tools. Every piece of it made by hand.
Of course, with the modern processes we also lose the ability to get something truly unique and made with love and imagination.
I think it is wonderful that some people are trying to start making things like cut glass from scratch again. Good luck to them.
