What is a thimble used for?

sewing.

A thimble is a small, hard cap worn on the finger over the nail to protect it when sewing. It is usually made of metal, such as zinc or silver. The thimble has a small indentation on the top, which allows the needle to be guided through the fabric without injuring the finger. Thimbles come in different sizes to fit different fingers, and some are designed with decorative engravings or patterns. The use of a thimble not only protects the finger but also provides a better grip and more control over the needle, making stitching easier and more accurate. Thimbles have been used for centuries and remain an essential tool for professional and hobbyist sewers alike.
