A black butterfly tattoo cover up is a way of covering up an old, unwanted tattoo with a new, more attractive design. The cover up technique can be used to cover up anything from a simple black butterfly to an elaborate full body tattoo. Cover ups involve the use of black ink to cover up the existing tattoo, while the new design is added over the top. It’s a great way to give a worn-out tattoo a new life without having to go through the painful process of getting it removed. Black ink is often used as it’s a good way to blend the old tattoo with the new one.
