Glitter Toes-eborah lippmann nail polish is like this but the dots of glitter are smaller. This is done by someone who does glitter toes. Straight glitter, with gel or acrylic over it. Not a nail polish.
Put water in a bowl, drop random colors of nail polish in and swirl with toothpick. put petroleum jelly on your fingers so the polish only sticks on nails not your fingers. Stick fingers in bowl, nail polish should float on top of water.
