Choose a color you like as the background color. If you want to apply evenly, apply it forward from the middle of the nail root, then apply it along both sides of the nail, and then apply it evenly with a brush.
Scrape the nail polish brush back and forth at the bottle mouth several times, scrape off the excess nail polish, and scrape the brush into a small fan shape, leaving pea-sized nail polish in the direction where you brush the surface. The brush forms an oblique angle of about 60 degrees with the nail surface, and brushes from left to right. After brushing, brush from right to left in the same way, and finally brush the decorative radian again at the junction of the two strokes. Finally, don't forget to brush a layer of bright oil to fix it, and you're done.
Another way is to use stickers, of course, this sticker can be bought specially, or you can use double eyelid stickers. Paste it several times before use to reduce the viscosity, otherwise it will damage the painted nail polish. Stick the sticker on the nail whose nail polish is completely dry, then apply it horizontally with another color nail polish, and then remove the sticker after it is completely dry. If you are creative, you can add paintings, diamonds and the like. Of course, don't forget to brush the polish at last.
The last method is to use white line strokes, which is most suitable for beginners. The line pen is thin and long, so it is easy to draw a beautiful arc at one time. It is worth noting that the finger to be drawn is fixed in one position, otherwise it will become a big arc when shaking, which is not beautiful. Draw the radian first, then cover it with white, and move quickly, otherwise the white nail polish will not blend together.
