This is approx. 7.25″ (18.5cm) in diameter.  Black Unipin pens and polychromos pencils on heavy, acid-free cartridge paper.

It took two episodes of Criminal Minds to do the pencil pattern and then to go over it with ink.  Another three or four episodes to complete the colouring, and another one or two to complete the texture lines.

I’m enjoying doing these; they’re very calming and meditative to do as there is a lot of repetition in producing the finished piece as they are geometric in design.
