It's apparent that my cousins and I are so into nail polish and nail art. One rainy Saturday morning, we tried doing gradient nails. The results are just lovely.

The process is really easy. All you need is a small piece of dishwahing or make up sponge, and two nail polish colors. Use the lighter nail polish as your base, then pour a little of the two colors beside each other on a piece of plastic or aluminum foil. Stamp the colors on your nails using the sponge, et voila, you have gradient nails.
