Start with clean nails, you may need nail polish remover& a cotton ball. (mine are slightly stained from dying my hair)
File your nails to the desired shape
Choose a color to paint your nails. You can add a base coat here if you want to. I'm skipping this step.
Start by painting one line down the middle of your nail
Use a small amount of polish to fill in the sides
Repeat on all nails. When dry you may add design and/or top coat. Have fun painting!
