Parts of the Needle
Shank: top part of the needle that goes into the sewing machine
Shaft: main part of the needle. Below the shank.
Front Groove: slit on the front of the needle where the thread sits while sewing which protects it from breaking.
Scarf: skinny space in the back of the needle which helps prevent skipped stitches. The scarf is longer on stretch needles to accommodate the fabric.
Eye: liked a hand-sewing needle, the eye is the hole where the thread goes, but the eye of a sewing machine needle is on the opposite side.
Kinds of Needles
Universal Needles: sharp and slightly rounded
Ball Point Needle: knit fabric- very round
Stretch Needle: knit fabric- very round with deeper scarf to prevent skipped stitches
Jean Needle: woven fabric- sharp, thick, round
Twin Needle: two needles connected so it can be put in the machine like one. The stitching on top is two parallel stitches with a zigzag on the bottom
Leather Needle: leather- sharp
Smaller needles are for thinner thread so that it can fit into the front groove. Larger needles are for thick thread but don’t work with thin thread because the thread will flap around inside the front groove and break.
