If you were creating a lamp by hand what type of material would you chose for the wiring and what material would you chose to coat the wiring? Why

A lot of it is all experimental as long as you are taking caution of safety while doing it. I personally would use copper wiring mainly for the fact that it is a nice conductor. For the wrap around the wiring i usually would use black or red electrical tape just because it has very nice insulator properties and is safe to use.
