Paint the skulls eye’s, mouth and bow once the skull paint has fully dried. Create two small dots for the skulls eyes in the middle of the large, white circle you painted. Use a toothpick or a nail art stripper to create the teeth by painting three straight lines down the middle of the rectangle. Draw the bow using black nail polish on the side of the skulls head using a toothpick or nail art stripper and add a small faux diamond in the middle of the bow using nail glue.
