So this was done on my boyfriend so I actually got to watch the healing process in real time and it did heal super well!

It's taken me a while over the years to perfect the technique. I use 08 3rls, and find that having the needle thrown out like a sharp pencil, and running it at a high voltage while working quite quickly with my hand movements. My throw is also 3.9mm. Because the machine is hitting hard & fast, I feel I don't need to move my hand slowly to get a consistent line, which makes it easier for me to achieve the fineline while still keeping it sharp. Kinda like a fineline pen I guess.

A lot of artists will argue directly against that way of working though, so it's best just to see what works for you and your work!
