You do that by gently lifting your pencil clear at the end of each line. The solution is tapered lines.įirst, varying the length of the lines helps to prevent a visible edge, but to banish it completely, taper - feather - the ends of all your lines so they fade to white. And adjacent shading will overlap that edge and create a double layer of graphite, rendering it even more noticeable.
For example, if all your lines just stop there will be a visible hard edge down your paper. When you shade large areas, the shading will inevitably need to be carried out in sections, and that presents problems.
