Stuff it up with acid-free tissue paper (the stuff that they usually stuff bags with or wrap clothes with when you are purchasing them) to the desired shape, being sure to push up any creases on the vertical seams when the bag is set upright on a flat surface. Store the bag upright.Thank you! It's so wrinkly I don't know how to store it or use it now. Is there any way to "iron" it out? Or there's no way to save it?
This will reshape the bag to a small extent, but with the leather having softened already, it won't ever look like the new structured Peekaboo bags.
