The chiseled pencil end makes quick work of defining and shading the brows. Just start by marking off the front of your brows, which should be in line with the tip of the nostril. Then, lightly mark your arch as well as the brow tail, which should end in line with the tip of the nose and outer corner of the eye; you can find this by placing your pencil diagonally along this path to find the brow’s tip.
