To repair a cracked nail with a fabric wrap, one should cut a repair patch that covers:

When repairing a cracked nail with a fabric wrap, the goal is to ensure that the entire crack is properly supported and secured to prevent it from worsening or splitting further. By cutting a repair patch that covers the entire crack in the nail, you provide adequate reinforcement to help restore the nail's strength and durability. This approach not only aids in the immediate stabilization of the damage but also promotes healing by keeping the area protected.

Using a patch that extends beyond just the visible part of the crack ensures that any hidden damage beneath the surface is also addressed. If the repair is limited to only a portion of the crack, it may eventually lead to further issues, as the unsupported sections can continue to break or separate. Therefore, covering the entire crack is essential for a successful repair, ensuring that the integrity of the nail is maintained throughout the healing process.
