I loved making lines with ink.  I think my brush was too soft and I held the wrong angle a few times with the ruler, but it was great practice to see what I liked and what I didn’t. I used burnt umber ink (my initial learning marks were the wavy ones bottom left).  I got faster and more confident with it as I moved across the page.  I tried to paint with ink over it afterwards since I do not have photoshop, but the lines showing through were distracting and I opted for an acrylic marker sketch over top of the ink lines instead to finish my project.
