What is the term for the sewing tool that is a round metal spool which holds the bottom thread?

• A. Needle
• B. Bobbin
• C. Spool pin
• D. Thread guide

Answer: (B)

The term is bobbin. It’s the small round spool that holds the bottom thread and sits in the bobbin case under the needle plate. As the needle thread forms a stitch with the bottom thread, the bobbin supplies that underside thread to create the lockstitch. The other items have different roles: the needle carries the top thread, the spool pin holds the thread spool on top, and the thread guide directs thread from the spool toward the needle. Understanding the bobbin helps explain how stitches are formed and why tension matters.
