This is a tutorial I did for the hearts mani.
1: Apply base coat and colour. I user a shimmery nude, revlon cotton candy
2: Make 2 dots, one above the other on the nail. These will be the points of the heart.
3: Using a striper brush/polish, carefully draw one side of the heart
4: Carefully draw the other half of the heart, keeping it as symmetrical as possible.
5: Load up the striper and paint the base half of the nail and up the sides.
6: Using the polish brush, fill in the rest, making sure to wrap the tips for best durability.
In my previous post, you can see I added glitter borders. You can do whatever floats your boat.
Have fun, and let me know if you use this so I can check it out!
