A slender, sharply pointed metal implement, specifically designed for use with a sewing machine, forms a stitch by carrying thread through fabric. Different types cater to various fabrics and thread weights, ranging from delicate silks to heavy denim. For example, a heavier weight denim requires a stronger, thicker point than a lightweight chiffon.
Proper implement selection is crucial for successful sewing. Choosing the correct type prevents skipped stitches, broken threads, and fabric damage. Historically, the development of specialized machine implements was a significant advancement in the industrial revolution, paving the way for mass-produced textiles and clothing. This evolution continues today with advancements in materials and point designs for specialized applications like embroidery and quilting.
