A blackout tattoo sleeve can be created by an artist to either cover an unwanted previous design, or add a new bold statement to this prominent area of your body. Often the whole arm is tattooed in black, or white can be added to create a delicate design as part of the tattoo sleeve. If not a cover-up, negative space can be left to create an unique tattoo design. A blackout sleeve won't happen overnight - many sittings are involved in this slow process, as well as the obvious pain before and in healing. A tattoo sleeve isn't a quick fix but rather a tattoo decision that requires 100% commitment.
