Q&A for How to Repair a Zipper when the Slider Has Come Off Completely

If your entire zipper has become detached, it is probably best to sew it back in place. Stitches will hold your zipper in place more reliably than glue, and glue also has the potential to interfere with the teeth of the zipper if it is not applied with care.

First of all, don't rush yourself. Try to peel out the fabric stuck in the zipper by slightly moving the zipper, or grab a toothpick and try to pluck it off.

There is no easy way to replace the bottom stop on a split/separating zipper, especially if the fabric of the zipper tape is frayed. You may need to replace the entire zipper. If one of the top stops is missing, you can crimp on a replacement stop with pliers if the fabric is not too damaged.

You will need to buy a new one from somewhere. Fortunately, there are many places where you can buy inexpensive zippers, such as craft stories and stores with craft or sewing supplies, either real or online.
