I acquired an IRS #361 strop that had been stored for several years and folded in an "S" shape. There is a 6" section where the leather was folded inwards. It has been hanging for several weeks now and I have used mink oil on it. However, this section continues to have wrinkles crossing the strop, not going lengthwise. There is a noticeable texture to these wrinkles, but it is not dramatic.

Should I work to remove the wrinkles or not worry about them?

What should I use to remove them if need be - pumice?

Should I try to correct by bending in the reverse direction?

Thanks for your help
