1. Hand wheel: Turn this wheel to adjust needle height. Always turn the hand wheel toward you.
2. Spool pin: The spool pin keeps the spool in place while the thread feeds through the machine. Some machines have both horizontal and vertical spool pins
3. Spool cap: The spool cap slips onto the end of the spool pin and holds the spool in place.
4. Bobbin pin / winder: Built-in bobbin winders may be found on the top, front, or side of a sewing machine. Most winders consist of a bobbin pin to hold the bobbin while the thread is being wound, thread guides for maintaining tension, and a start/stop lever. Some bobbin winders have built-in thread cutters.

5.Thread guide: Thread guides may be hoops, discs, or flat metal shapes that pinch or direct the thread to feed it through the machine without tangling and at the correct tension.
6.Take-up lever: The take-up lever is a metal finger with a thread guide that moves up and down, pulling thread from the spool and feeding it through the machine.
7. Stitch selector: Use the stitch selector to choose which stitch you’d like to use. Many machines feature a number of built-in stitches: straight stitch, zigzag, buttonhole, blind hem, etc.
8. Presser foot: The presser foot works with the feed dog to move fabric evenly through the machine. When the presser foot is lowered, it engages the tension discs and presses the fabric beneath the foot against the feed dog. The upper part of the foot, called the ankle, is usually screwed onto the machine securely; the lower part may include a quick-release mechanism for changing presser feet.
9.Presser foot pressure control: This control adjusts the amount of pressure the presser foot applies to fabric as it feeds beneath the needle. Increase pressure when sewing heavy fabric and decrease pressure when sewing lightweight or thin fabric.
10. Presser foot lifter: This lever, located above the presser foot at the back or side of the machine, raises and lowers the presser foot. When the presser foot is lifted, the tension discs are disengaged, and the fabric will not feed through the machine.
11. Needle: The needle carries the upper thread through the fabric to create a stitch. Specialty needles are available for specific stitching needs.
12. Needle threader: Some machines have built-in needle threaders. Threaders have a tiny hook that swings through the needle eye catches the thread, and pulls it back through the eye when the threader is released.
