There are many features of leather which make it so attractive to consumers the world over. One of these features is leather's resilience. A properly maintained leather will never look old and will therefore outwear textiles many times over. Since fabrics are woven, changes in their appearance from age and use detract from their beauty. Leather will actually absorb body oils during use. These oils, which are damaging to textiles, will actually enhance the leather's appearance making it more beautiful over time. This improvement in appearance is called patina.
