Scroll Down to Day 1 for an explanation.
Today I used a pen a uni-ball Eye "micro" made by the Mitsubishi Pencil Company.
I also took longer - twelve minutes - making a larger image and taking a little more time to place the freehand marks on the paper. The method of shading is that which I use when making a preparatory drawing for an engraving. The direction of the lines is the direction that I would move the graver.
This is the ink that I use, greatly diluted, to darken the blocks that I engrave.
