For a subtle brow, start by creating soft, individual, hair-like strokes beginning towards the beginning of your brow. Move in light, upward motions, following your natural arch. Diffuse any harsh lines by using the spoolie side of your pencil.
For a bolder brow, apply with more pressure when drawing in your hairs. Next, fill in your brow with soft, even strokes to create more intensity. Going back with your spoolie, diffuse the brows slightly, to keep your bolder brow, but soften any harsh lines.
Tips: Create a starting point for even brows by drawing a soft line along the base of your natural arch. Create a stopping point for your brows by dotting where you want your brows to end before you fully commit to drawing them in.
