Swirl pink and sparkly white acrylic onto the free edge. Shape the smile line before the acrylic dries. Fill in the rest of the nail with sheer sparkly pink acrylic.

Use a striper and white acrylic craft paint to add two lines in the top corner. They should start from the same point, then curve out slightly.

Use a dotter and pink and white acrylic craft paint to create hearts all over the nail. The easiest way to make a heart is to make two dots side by side, then drag the paint down slightly to a point.
