Guess it could be done even more efficiently with a garment steamer (which I don't own) or a household steamer (which I own, but it's an old, bulky model and bringing it from the basement is a big deal and calls for a serious project). Being quite a sporadic visitor on this site in general, I don't read the thread as religiously as some devoted rehabbers, so my knowledge is covered in huge holes, LoL! I vaguely remember that a couple of years ago someone here wrote about working on removing the dents from Italian Kelly bag with a steamer because she didn't want to dunk it. That creative person used a small hole in a seam to insert a narrow nozzle between leather and the lining. I don't remember the details, unfortunately, as well as the full outcome of that experiment, but it was mentioned in the process that there were positive changes. So somehow I thought of that idea, but decided to use a less sophisticated pot-and-stove method
