First of all apply a base coat for protection. After the base coat dries you can start the nail art but you'll have to complete one nail at a time. Apply a coat of white nail polish on your thumb nail.
Be quick, draw a line in the middle of the thumb nail with red nail polish.
Draw 2 lines on both sides of the red line with pink nail polish. Keep gap between the lines.
Use a pin and drag it through the nail polish horizontally.
Do the same for every nail. After the nail polish dries apply a coat of clear nail polish. Enjoy!
