SEWING NEEDLE A sewing needle is a long slender tool with a pointed tip. The needle must be able to penetratethe material being sewn, by pushing the yarns aside according to the application, without damagingit.

Parts of needle 1. ShankThe shank is the upper portion of the needle that is inserted into the machine. The front is roundedand the back is flat. Home sewing machine needles are composed of a flat and a round side, toassist in always having the needle in the correct position. 2. ShaftThe shaft is the lower portion of the needle that begins at the base of the shank and extends to thepoint. The needle size is determined by the shaft diameter. 3. GrooveThe groove is the indentation located on the front of the needle. The thread is protected in thechannel as the needle passes through the fabric. 4. ScarfThe scarf is the indentation on the back of the needle above the eye. The scarf allows the bobbinthread to pass closely to the needle eye catching the needle thread to create a stitch. 5. EyeThe eye is the hole in the lower portion of the shaft. The thread passes from the front to the back ofthe needle through the eye.

PointThe point is the tip of the needle that penetrates the fabric. Needle points are designed to penetratedifferent fabric types.
