Here are the steps to fill in your eyebrows:

1. Consider your skin tone.
2. Start filling in your brow using a powder. Touch your brush (a small, angled eyebrow brush is recommended) in the brow powder, tap off some excess powder on the side of the powder container, and start to lightly fill in the top and bottom edges of your brow. When filling in, follow in the direction of your hair growth.
3. Use a brow stencil to get the perfect shape.
4. Fill in the rest of your brow.
5. Brush out the color.
6. Check your work.
7. Set your brows.
