What is a "thimble"?

A thimble is a small, cylindrical tool used to protect the finger when pushing a needle through fabric or other materials while sewing. It is typically made of metal, plastic, or leather and is worn on the finger like a ring. Thimbles can also be made of other materials such as bone, ivory, or wood. They come in different sizes and shapes to fit different fingers and are often decorated with decorative designs or patterns. Thimbles help to prevent injury to the finger from the sharp end of the needle and can make sewing more comfortable and efficient. They are an essential tool for sewers, quilters, and anyone who works with fabric or leather.
