Sven Rayen is an utter master of single-needle tattooing. His work looks like someone took the fine art drawings right out of the Museum of Modern art and etched them onto skin. Except with a single fucking needle.
Imagine you've got a buddy who's just super sick at ballpoint pen drawing, or maybe she only works with super-thin mechanical pencils to create beautiful, detailed grayscale work. You may even have some folks in your life that have these twistedly magical talents, and you've seen them in action — now apply that to the notion of single-needle tattooing. Most tattoo needles are multiple-pronged, even the finer lines are done with three needles packed together, but single-needle tattooing is exactly how it sounds: one single needle.
Scaling to scale!
Goodness, that there summery chair is cute.
Single-needle tattooing lends itself to really, really fine detail. C'mon, it's a single needle! It better be detailed! So spikes on a cactus or bones inside a whale suddenly become extra dainty.
