1. Using a Q-tip, apply a thin layer of Vaseline on skin around nail. This is not essential, but it does make it easier to clear away unwanted polish.
2. Fill a small cup with cold water. Add a few drops of each color polish you want in your marbling. The polish will float on top, creating swirls.
3. Dip each finger and make sure the polish sticks to your nail. Let dry, then clean edges. Finish with clear top coat.
