The document discusses three main types of nail art designs: nail art stickers, stenciling, and airbrushing. Nail art stickers come in various designs and are simple to apply. Stenciling involves painting nail art designs onto stencils or using airbrushing through a small stencil. Airbrushing is usually done professionally but can also be used on natural nails. These methods allow for many different nail art design possibilities including flowers, jewels, and seasonal images.
