First, select your subject. The best subjects for pen-and-ink drawings are things in nature. I chose a jellyfish- nautical subjects usually come out really well.
Sketch your subject in pencil. Make sure not to make it too dark, but you should be able to see it clearly.
Next, find a fine-tip blue or black pen. For best results, try using a Pilot Precise v7 Fine Rolling Ball pen. Almost any blue or black pen will work, as long as it has liquid ink, but try the Pilot.
Gather the rest of your supplies- all you should need is your drawing, your blue or black pen, a cup of water, and a paintbrush. The paintbrush should be fairly small to help paint precisely.
Trace your drawing for about a centimeter, then wet your brush and paint over it. Let the water sit for a minute to make the ink run, then grab a tissue and blot up and remaining droplets.
Another cool tactic to try is wetting an area, then tracing the drawing.
Here's the finished product. It's still wet, and may look slightly darker when it dries. Adjust your pen color accordingly before you start.
I had to change my pen a few minutes in because I ran out of ink. Here's another drawing I did all with the Pilot v7 pen.
