Input: [header] How to apply nail tattoos [title] Apply a base coat and nail polish. [step] Brush on a clear base coat. Once it's fully dry, brush on at least one to two coats of nail polish-allowing it to dry between coats-until you achieve satisfactory coverage. <sep> (A) [substeps] Because the edges of temporary tattoos often have a translucent, filmy border, opt for white or light-colored polish. This will also make a canvas for good contrast with your tattoos. (B) [substeps] If you don't like a thin base coat, choose a lighter base coat. For a thicker base coat, use about one to two coats of polish. (C) [substeps] Let the base coat dry before marking your mark (s). Applying nail polish at night makes working with oil-based adhesives more difficult, especially if you've created a thick layer of adhesion. (D) [substeps] Apply two thin coats of base coat to the entire perimeter of your tattoo. In the second coat, apply a second layer, allowing for even coverage.
Output:
A
