This was put aside for awhile because of lack of focus on anything, but I finally pulled out a fountain pen and did it. I used Platinum Carbon Black, but it makes too thick a line on this paper to suit me. The pen point is Lamy Safari extra fine, so it's the ink on this paper, not the pen point. It is a very inexpensive sketchbook. If I were using a larger size of paper, the thicker lines would be more appropriate for me.
