According to The Independent, after waning years, sewing machines are making a come back among sewers. The parts of the sewing machine should be recognizable for easy usage.
The bobbin winder is on top the machine. It winds thread around the bobbin. The spool pin holds spools. The stitch length knob controls stitch length and the stitch width knob controls the stitch width. Thread guides guide the thread. The thread take up lever has a slot or eye and controls the thread. The upper tension control determines thread tightness.
The hand wheel is found on the side and adjusts needle height. The reverse sewing button is a lever or button allowing reverse stitching.
Beneath the arm is the needle. Under the foot is the needle plate. Within the plate is the feed dog, which determines fabric motion. Above is the presser foot, which grips fabric for movement.
Inside the machine is the bobbin case. It holds the bobbin controlling lower tension. Thread is fed into the bobbin from the shuttle hook.
Except the pedal, mechanisms are protected within the case. The pedal, powered by the sewer’s foot, controls the machine’s speed.
