3.The lettering quill won't hold as much paint because of its shorter hairs, but it will provide more control over a long liner. Steve wasn't overly concerned about the edges because he planned to come back and outline them in black. He did pass along a little tip: Cut into your line or sneak up on the edge. Don't just put the brush right on the line and pull. Instead, set the brush close to the line, and then as you pull drag it over and then follow the line.
