Inking straight and circular lines is tough at first. Like most things in life, this too gets easier with practice. That’s how generations of artists became experts with these very same tools. The steps below are merely guides; only your hard work will make these tasks easier!
Straight Lines with Ruling Pen
Ruling pens make same-width lines. Dip into your ink like a drawing pen, but wipe the part of this pen that touches the ruler. Hold the ruler at a 45 degree angle, with just enough pressure to keep it still; more will cramp your holding hand and less will make a sloppy line. Keep the top edge of your ruler (the part that touches your pen) off the paper!
Straight Lines with Drawing Pen
Drawing pens make variable-thickness lines. Same principles as with the Ruling Pen. It’s a little more difficult, but produces a line with more character.
Straight Lines with Brush
Sable brushes make slightly-unpredictable lines. Same principles as with the Ruling Pen. It’s a little more difficult, but produces a line with more character. Make sure the ruler touches the metal part of the brush, not the hairs.
