Flipping a U turn – on technique

Traditional tattoo methodology would have the artist work from
darker to lighter areas of the tattoo, building up shadows and
darker areas. This is not always required, but it is good practice.
As a new tattoo artist, one should not get frustrated if the
ink does not appear to be going into the skin properly. How easily
the grey values will build depends on a lot of variables. These
things require time, patience, and practice. It is also possible to
over work and ultimately damage the skin.
