In the next steps we will show you how to easily shorten a metal zipper. First you measure the distance on average and transfer the exact length to your zipper.
To shorten, the overmeasured prongs are pulled out with pliers from above. Note that the first prong after bending open must be picked up and put back on later so that the slider does not slide out upwards.
The zipper can now be worked into the front parts. Orientate yourself on the snaps in the cut.
Have lots of fun with it
