Create a dark, eerie background using deep purple or black nail polish, and then paint a haunted house on one nail.
Jack-O'-Lanterns are a classic symbol of Halloween, and they make for a fantastic nail art design.
For a more sinister look, try the blood drip nail art. Apply a deep red or black base coat to your nails, and then create the illusion of dripping blood using a bright red polish.
Paint your nails a dark green or black shade, and then create witchy accents like pointy hats, broomsticks, and cauldrons.
Begin with a dark background color like black, purple, or deep blue, and then use white or silver polish to create intricate spider webs on each nail.
Mummies are another iconic Halloween figure, and mummy wrap nails are an adorable yet eerie choice.
