Zippers make it easy to put on and take off clothes. All Zippers open and close through the action of a self-locking slider and pull tab. There are three types of zippers, distinguished by their teeth: a polyester interlocking coil, molded plastic teeth, and stamped metal teeth. All of these teeth styles are attached to a fabric (usually polyester) tape.
Shortening a zipper
If you can’t find the right length zipper, buy a longer one and shorten it. Close the zipper and mark the desired length. Straight-Stitch several times back and forth over the coil or teeth at the mark. Trim the zipper 1/2″ (1.3cm) below the stitches.
