As long as people wear suede and leather garments, they’ll make holes in them. Cigarette burns, punctures or pinches might cause the holes.
When the skin is burned through or a piece of the skin is missing, the usual mending method won’t be practical. The missing piece of skin needs to be replaced with a piece that matches the surrounding area in color and texture. For example, if the surrounding skin is a red cowhide, the replacement piece must be a matching piece of red cowhide.
