The old hanging with weights or putting it between stacks of books or weights or using a rolling pin are possibilities. If all else fails and there are creases or heavy wrinkles in it you can use the nuclear option, soaking in water and letting it slowly air dry however that's a last ditch effort before the trash can.

Sometimes these old strops are just dried out and there is little you can do.
Interesting, great information. Thanks!
