Step 1: Paint your nail a solid color.
Step 2: Take the orange nail pen and make solid dots in the two opposite corners of your nail. Then draw curved lines coming out from the dot to make the firework.
Step 3: Take the white nail pen and add white tips to all the curved lines you made. You may also add white stars in the other corner of your nail.
Tip: Protect your nail designs with a clear laquer nail polish.
