Sewing machine threading diagram illustrations use letters or numbers to mark components of the sewing machine. When the instructions in that step reference a component, they includes that component's letter or number, usually in parentheses. If a step has multiple illustrations, each illustration has its own label, such as "figure 1" or "figure 2." In these cases, when the instructions reference a component, they include the figure with the component's letter or number.

Threading diagrams are available in the machine's owners manual and may also be available on the company's website. Sewing machines tend to have similar designs, so threading is a similar process with most machines. However, designs can vary from one machine to another, so threading a machine is easiest when using the diagram provided by the manufacturer.Learn more about Sewing
