Why does a tiny thimble help someone sew?
A sewing needle has a sharp point and a small blunt end near the hole for the thread. Pushing that little end with bare skin can hurt. A thimble puts a firm cover over part of a finger.
The needle’s blunt end rests against the outside of the thimble. The finger pushes against a broader surface inside. The cover helps spread that push over the finger while sending it into the needle.
The needle points toward the cloth; the thimble meets its blunt end. This cutaway explains the tool, not a sewing activity.
Many thimbles have little dents or a rough surface. These help keep the needle end from sliding sideways. The thimble guides and protects the pushing finger; it does not make the needle’s sharp point harmless.
A small object can solve two problems at once: where a push goes and where it is felt. The needle needs a tiny point to enter cloth, while the finger benefits from a wider place to push.
About this explanation
Thimbles have several shapes and materials; no design protects against every needle slip or puncture.
Starting knowledge: Know that a needle passes through cloth and that a small point presses on a small place.
