Once dry, tape your nails off so that the painter's tape wraps around the outer portions of the nails and crisscrosses at the cuticles. The goal is to create a triangular shape at the free edge. Next, paint just the exposed portion of the nail with the opposite polish color. Orange bases will get a black accent, while black bases will get an orange topper. After allowing the polish to dry completely, slowly pull the tape off to reveal nails that are more cool than ghoul.
