Step 1:
Paint a corner of your nails any color (I chose purple) don't worry too much about having straight lines because the outline will hide those minor details.
Step 2:
For this step I used a light green color, paint a vertical line on the other side of your nail. Is okay to go over the purple a little bit.
Step 3:
Now choose another color and make a small triangle in between the purple and the green. Once again don't worry too much about the lines being straight and is okay to go over the other colors a little bit.
Step 4:
Fill in the space that is left with another color.
Step 5:
Now here come the more difficult part. Using a very thin brush**, draw the lines surrounding all the shapes. You can use white or black. Make sure you have a steady hand or ask someone for help!
**If you do not have a thin brush just buy a paint brush from the dollar store and cut the little hairs to make a thin brush**
