Use a cotton swab to wipe down your nails with white vinegar before applying basecoat. This removes any product buildup or natural oils on your nail beds that could create a barrier between the polish. Once your nails dry, apply basecoat.
Stamped using an image from UberChic using Konad Black Pearl special polish. (In hindsight, the nails looks closer to the art without the stamping but oh well lol) Go to site for detailed instructions.
