Recently bought a light weight /fountain pen by Speedball. Always wanted to try to draw with this type of pen, saw people use it to write with it, looked super easy. However it took me at least an hour to get use to the idea of producing really thin fine lines and a nice pressured thick outline. At most I poked several holes on one page, not knowing how much ink the tip could carry and how much presaure I could exert with this pen.
After several dabs of the indian ink the pen came with, I am quite happy with some of the lines. And it was a nice stress reliever :)
