Which term describes the decorative technique involving layering?

The term that describes the decorative technique involving layering is known as an inlaid design. This technique involves embedding or layering materials, such as colored gels or acrylics, to create a pattern or image that stands out from the surface of the nail. By strategically placing different colors or types of materials on or within the layers, nail technicians can achieve depth and visual interest, which is a defining characteristic of inlaid designs.

In contrast, other techniques mentioned have different focuses. The faux technique typically refers to imitative methods that mimic the appearance of other materials, rather than layering. The marbling technique involves creating a swirling effect with colors but does not necessarily include distinct layers; instead, it blends colors together. Freehand drawing is a technique that involves painting designs directly onto the nails without layering, focusing more on skillful application rather than structural depth.
