A few weeks ago I did these marble nails. They were super easy! First, start off with a white base coat. Let it dry COMPLETELY before you move on to the next step. I would even recommend waiting a day between these steps, although it’s not completely necessary. On some of my nails, the white, even though it felt dry, ended up smearing in with the colors when I went on to the next step, which doesn’t look as good.
Next, choose a few colors for the marble part. I used 4 different bright colors. Take the colors and drip dots of them onto the nail. It doesn’t matter if the colors run into each other. Then, while the colors are still wet, take a plastic bag, like a sandwich bag, and put it on top of the nail. Push down so the colors merge together, and smear them around a bit. Wait for them to dry, add a top coat, and that is it! You might need to do a little clean-up on the skin around the nails, which you can use a q-tip for.
