My crosshatching fractals started as an exercise in completing work that would otherwise drag on, forcing myself to accept when a piece is done.

I started them as someting to do when tendign the till an a retail job I had years ago between customers on printed recipt paper, and evolved into a daily therapy to get through the worst year of my life. 

Today they are a sort of meditation I complete each morning while finishing my coffee, experimenting with different pen types and nib sizes.

When a completed design seems especially interesting, I will scan and digitize it, altering with photoshop curve menue to remove imperfections.

I also occationally vectorize those I think would benefit from the image trace menu and simplify\curve commands in illustrator.
