Too much time, too little gain, just buy a new pair.
Just need an extra inch in my jeans after Thanksgiving.😂. Tried this while waiting to lose the weight.  Washes jeans and hung them outside to dry. Finally, got the stretcher in and adjusted. Of course, it’s cold and took forever to dry.  Got to wear them the next day.  There was a little difference but easier just to buy one new pair or use button extender until I lose the weight, Sorry.
