I have been asked by an older gentleman who is really attached to this bag if I can address the edges. I didn't take a picture of the bag, but found one for demonstration purposes. The entire edge on both sides is rolling inward when the bag is set down on a solid surface. The leather is in good shape, supple, but also very soft. I think over the 40 years it has been used, it has created a memory and will always go back to that position, even when I pull it out. Any ideas on how to fix the bag so the edges don't roll under the bag? Thanks!!
