To safely sew, one should have proper lighting, sit up straight with their left foot higher than the right, and arrange sewing materials nearby. The sewing machine should be in good condition and operated slowly without sewing over pins. Long hair should be tied back and fingers watched to avoid pricks from the needle. Scissors should be handled carefully, a thimble used for hand sewing, and pins/needles stored in a cushion. The machine should be unplugged after use and the work area cleaned up when finished sewing. Following these practices prevents risks and accidents while sewing.
