Bill, Use will eventually iron out the folds. The leather fibers in new leather are stiff and don't slide easily. The more leather is used the more flexible it becomes. No potion or oil.. just use will do it. Try wrapping the sling backwards when you roll it up. Then forwards the next time. While it's open you can roll it and twist it. You really can't hurt it by using it in a normal way.
