Most burns seem to be made bye either a match head, or a dropped cigarette. Both of these situations are repairable. The more charred the wound the more difficult the repair. The burning generates a puckering around the wound that’s a result of the heat shrinking the leather. If the leather is burnt all the way through than in order to affect that repair the   charred area needs to be cut away. With the charred area cut away the “puckering” is relieved.   When the “puckering” around the wound is allowed to relax what you thought was a hole the size of an eraser head turns in to a hole the size of a quarter.   It was ALWAYS the size of a quarter, but the “puckering” just made it look smaller. This wound can still be repaired, it just looks larger and now it’s ready to be repaired.
