How do I replace a zipper in a pair of jeans?
dgalloway, February 2005


done
get a replacement from john lewis, its easy to get and the people are friendly,
unstitch the threading holding your zip, then replace it, and stitch it preferably by mahcine.(its tighter and less prone to become loose by machine)
or take it to my dry cleaners on 173 york way camden london n7 9ln
