This is my husband's jacket's, and he really likes it, But, he broke the zipper. See the missing teeth?
Step 1: Gather Your Supplies
I also used a seam ripper and black heavy duty thread and a heavy duty hand sewing needle.
Step 2: Remove the Old Zipper and Replace It with a New Zipper
Pin the zipper in between the layers to ensure that everything lines up. Give the zipper a test zip to make sure it's straight with no puckering along the seam.
Hand sew twice on each side of the zipper, to ensure the seams are just as strong as the zipper.
