Candy corn is definitely an American Halloween tradition that us Brits have jumped on, and although it is hard to buy here in the UK, it makes great nail art. This technique is called ombré and almost always starts off with a white base coat. Once your white base is dry, paint the white, orange, and yellow polishes side by side on a makeup sponge and lightly sponge onto the nail; you may need to do this two or three times to get coverage (and be sure to wait until each layer is dry before going in with another). Don't forget the topcoat to seal the design in.
