I love ombre nails. I do them all the time. First you paint your nails one colour. Then you put the second colour on some paper or something and get a sponge. You dip the sponge in to the nail polish on the paper and then dab it on to your nails. After that you just paint over it with clear but i like painting over my nails with clear whilst the other nail polish is still a little wet so it mixes and doesn't look that harsh
