How to do the Ombre effect

First you need to pick out two complimentary colors and a top coat.

The tools you will need are : a Sponge, a plastic sheet, and toothpicks.

Using the lightest of the two colors paint your whole nail and wait for it to dry completely. 

Next paint a generous amount of the colors right next to each other, almost touching, on to the plastic.

Using the toothpick, swirl the two colors together.

Dab the sponge directly down on the two colors a few times

Dab the sponge directly onto the nail moving it slightly up and down your nail.

Repeat as many times as you want but make sure you wait for each to be dry first.

Add a couple layers of top coat after the colors are completely dry

Use a brush or q-tip doped in remover or pure acetone to clean up the nail.
