Step 1: Paint your nails with a base color. You can use whatever color you want! I just really love black nails so I decided to go with black. You could use pink or white for a more festive color!
Step 2: Use a nail dotter (or flatten the point of a toothpick) and make two dots right next to each other on your nail. These dots should barely touch in the center. Mine got really goopy and messy when I did this so that's why I only have a picture of one dot! Sorry! If you mess up, you can clean it up later with your base color.
Step 5: With your base color, use a really small dotting tool (or the pointy end of a toothpick) and clean up the edges around your heart so that it looks neater.
Finish with a top coat and you're done! This is how mine turned out! It's so cute!
