How do you handle client requests for cover-up tattoos, and what design techniques do you use to effectively conceal the old tattoo while creating a new piece?

Depending on the client's old tattoo that needs to get covered by a new one, I take into account the complexity, colors, and size of the old tattoo. Some tattoos require a few laser removal procedures in order to give the new tattoo breathing room. Whereas there's tattoo designs I've done that perfectly conceal the older tattoo with smart use of linework, shading, and coloring! It all depends on the client and their request.
