Doodling with a brush pen, and letting it be the boss. I wouldn't normally draw hair like this but that's what seemed to come out of the pen so I let it happen. This was done years ago with a really fat brush pen. I can't find those pens anymore and I liked them a lot. With light pressure I could get very thin lines, but it also had the ability to do extra fat lines as well. Now the only brush pens I can find are thin. My friend Brad keeps suggesting I try the real thing. I think I will when all the ink runs out of the pens I'm currently using.
