I love how gross and green these nails look! They are definitely one of my favorite Halloween designs I’ve done. Although I used mainly acrylic paints, the black background is Wet ‘n’ Wild Black Creme. After two coats of black, I painted a white circle in the middle of each nail, then filled them in with Kleancolor Bikini Green. Once that dried, I painted the shape of the hand, eyeballs, and tentacles in white, so the colors would stand out. As a final touch, I added some bugs in black and a few bubbles around the cauldron.
