How is the color of the tattoo filled?

I have two tattoos. Generally, the master will tell you the steps when tattooing.

And he'll tell you what we're going to do next when he gets a tattoo.

First, I use two needles to draw the outline of the ball (that is, a very thin and long pen-like thing with two needles at one end). . Tribal tiger)

Then the master told me to start coloring with 12 needle.

I'm ruined.

That's how it is colored, but the 12 needle is a relatively large area on the surface. Like a smaller place, you still need to fill 2 stitches bit by bit. Ha ha.
