Clean your hands and nails adequately before applying appliques.
Select a fingernail applique sheet from a package purchased at a department or beauty supply store. Cut out the applique you want with a pair of small, sharp scissors.
Drop the applique strip into the bowl of ice water. Let it float for just about a minute.
Peel away the thin plastic film covering the front of the applique. Carefully place the applique-side down on the center of your fingernail. Press the wet strip of paper onto your nail firmly and leave it there for 10 seconds.
Peel away the paper, exposing the applique on your fingernail. Let your nail air-dry for 20 seconds.
Apply a single coat of clear nail polish to the nail to seal the applique in place.
