In order to create a black, white, and purple nail design, you will need the following: black acrylic paint, a paint brush, purple glitter nail polish, white nail polish, and a shaping tool. Begin with clean dry nails that have been topped with a clear base coat. When the nail are dry, make a white hash mark on your nails. Line the design with black acrylic paint. Then, make a row of black dots down the center of the white paint. Next, using your purple glitter nail polish, paint the exposed fingernail tips, avoiding the painted portion of the nail. Allow it to dry.
