1. Put drops of nail polish into the water. Start with the lighter colour, as this will provide the base for the marbled pattern. Put about five drops of the lighter colour into the middle of the container, using the nail polish brush to help you get the liquid out. These drops should float and start to spread out over the surface of the water.
2. Immediately, put in about three drops of the darker contrasting colour, then use a toothpick to swirl the colours around and create a marbled pattern.
3. Press the top of the cardboard lid against the surface of the water, on the area with marbled patterns (above). Quickly, press all four sides of the lid against the surface of the water as well, and ensure that they are evenly coated with a thin film of polish. The nail polish pattern should adhere to the cardboard lid. If you find that any extra nail polish clings to the lid, use a toothpick to carefully remove the polish.
4. Run a toothpick through the surface of the water, moving it across the whole container, to remove any remaining nail polish floating on the water. You can use the same container of water two or three times before changing the water. If you do not change the water, oil spots will form which can transfer to your finished product.
- Repeat the marbling process to decorate the cardboard box. As the box is bigger than the lid, and there is a greater surface to cover, you may need to repeat the process several times. Remember to change the water when necessary.
- Once the lid and box are done, leave them to dry overnight so that the nail polish sets and the cardboard dries, before storing things inside the box.
Feel free to try the technique on other items as well. I first saw this technique done on shot glasses but check out these nail polish marbling ideas by Design Mom too. I tried it on wooden beads and managed to make myself a necklace. You can probably tell that the last blue bead was a little imperfect but I left it as it was because it was for me and I didn't mind. A little imperfection helps to remind me to take life easy and remember that I am imperfect too.
