Stencilling

In contrast to the freehand tags and throw-ups that are so common, some people do most of their work in private - carefully cutting out a stencil, sometimes simple, sometimes detailed. I suppose that this allows quicker execution of the graffiti in the field, without the need for as much illumination.

Interestingly (to me anyway), a technique that would seem to lend itself to mass production of tags is not used in this way - I have rarely seen stencilling repeated (with the exception of 'THINK" backwards, which is not uncommon. Stencilling also lends itself to commentary, and is used sometimes for this purpose.

Given my own (admittedly limited) artistic abilities - if I felt the need to spraypaint my existence somewhere - a stencil - perfected in private, promptly painted in the dark, would be my likely point of entry.
