In the right of the photo you can see the rainbow nails I have made. it's guide simple anyone can do it. first you apply a base coat on your nails then you put two layers of white nail polish on your nails. when your nails are dry you can put the rainbow colors on your nails. I use acrylic paint. the acrylic paint is faster dry. for the rainbow strokes I used a little brush but you can also use a toothpick.When the nail polish or the acrylic paint is dry the next you can do is to put a layer of top coat on your nails. enjoy!
