I saw this cute idea on the Essie instagram account, and had to give it a try.
I used Essie Sand Tropez, Set in Stones, and a cheap black nail polish, as well as some masking tape.
I started with a plain Sand Tropez nail.
Then, I took two pieces of masking tape.
Then I created a triangle, by crossing the two pieces of tape.
Next, I painted inside the triangle with black nail polish.
Then, I did the same with the Set in Stones nail polish.
Once it had dried, I pulled back the tape and painted a clear top coat.
