This is my self done tatoo. I poured the ink out of a red gel pen, dipped a brand new sewing needle in it and poked my skin repeatedly and deeply. It is on my left hand on the third knuckle.
My way is actually more pleasent than how they used to, see they used to sharpen a piece of bone into a bunch of tiny spikes, then they attached it to the end of a stick so that the spikes point downward. They then dipped the spiked bone into ink, placed it on the skin and tapped it into the skin with a weighted stick. Nowadays we use tatoo guns, a tatoo gun forces a needle many times repeatedly into the skin.
So the key to tatoo is piercing the skin and thus depositing ink into the skin.
When I turn 18 I will probably go to a shop and get a professional tatoo, though I don’t know what I will get.
Anyway, pretty wild eh?
