When applying a fabric wrap, which material is NOT included in the options?

When applying a fabric wrap for nails, leather is not included among the typical materials used. Fabric wraps are primarily designed to add strength and durability to natural nails or enhance nail extensions. Linen, silk, and fiberglass are all commonly used in this context due to their unique properties.

Linen is a strong fabric that provides excellent reinforcement, offering both flexibility and strength. Silk is lightweight and creates a smooth finish that's less visible, making it suitable for a more natural look while still providing significant support. Fiberglass consists of fine strands that are also strong and flexible, making it ideal for wraps as they can bond seamlessly with the nail.

On the other hand, leather lacks the necessary characteristics to effectively serve as a fabric wrap. It is not flexible enough to conform to the nail and does not bond well with nail products, making it an unsuitable choice for this application. So, the correct answer identifies leather as the material that does not belong in the category of typical fabric wrap options.
