Art is inexact by its very nature. Ink is a permanent medium. Making your drawings with ink takes a few steps to get from an idea to a finished picture. A pencil sketch can be refined and changed as many times as necessary as long as you keep the lines light so that the excess marks can be removed after your ink has been added with a fountain pen. Once the ink has been applied, dried and cleared of sketch remnants you will have a pen-and-ink drawing that you can enjoy for years.
Lightly draw your picture on a page from the sketchbook using your pencil. Take your time. Invent and refine your drawing as you sketch. Darken the outlines and shading lines of your drawing with your pencil. Focus on the finished shape and texture of the picture.
Dip the tip of your fountain pen into the ink. Trace over the finishing lines of your drawing with the pen while ignoring the excess pencil parks made while you were sketching. Wipe the tip of the fountain pen with a rag periodically and dip it into the ink again to obtain a uniform appearance. Allow the ink one hour to dry.
Trace over the outlines of your drawing with the pen and ink. Ignore the texture lines on your picture. Take your time. Wipe the pen tip periodically and make the outlines stand out from the shading lines. Let the ink dry overnight.
Lay the eraser shield on your drawing. Gently slid the shield along and locate the excess pencil marks in the slots of the shield. Rub each pencil mark with your eraser to remove it while protecting the ink drawing. Remove all of the pencil marks with your eraser and shield. Sweep the debris off of your drawing gently with your drafting brush.
