Wipe off one side of the nail polish brush on the side of the bottle. You don't want too much polish on the brush or it will flood your cuticles; too little and it will come out streaky. Use the “three-stroke” method. Start at one side of your nail, just above the cuticle. Using the side of the brush with the polish, push the polish towards your cuticle without touching it. Then, bring the polish up your nail in one continuous stroke. Dip your brush in the bottle again, wiping off one side of the brush, and repeat on the other side of your nail. If necessary, re-dip your brush and finish with the third brushstroke up the center of your nail. Repeat with a second coat of polish, allowing the nails to dry for a few seconds between each coat.
