Okay, pencils are not evil. But they are not the best choice for children to use when writing for school work, as Andrew Pudewa (Institute for Excellence in Writing) deftly argues in his article, "Convert . . . to Pens!"
I am so glad I read his article before beginning penmanship with Katherine. While he applies his argument mostly to the use of pens for writing composition, his points about avoiding erasing, increasing visibility, and ergonomic concerns apply at least equally well to introductory penmanship lessons. Read for yourself and be converted!
