In this lesson, students are exploring the anatomy of a sewing machine, focusing on various parts and their functions. Key components discussed include the spool pin, which holds the thread in place, and the bobbin winder, used for winding the bobbin with thread. Additionally, the lesson covers the balance wheel (handwheel), which is utilized to lower and raise the needle for sewing. Students will learn about these parts through hands-on activities and visual aids in upcoming lessons.
