[header] How to shave your neck when growing a beard [title] Visualize a line from one ear to the other. [step] Imagine a line that loops from the back edge of each ear down and around the top of your neck. Envision the lines meeting in the center of your neck (below your jaw). <sep> (A) [title] Close your eyes and draw a line halfway along the back, below your cheekbones. [step] Be aware that this should be both long and tapered, to simulate a straight neck in this image. (B) [title] Visualize two lines extending down from your sideburns.
