Hi Miriam, not sure what kind of damage you have to your leather, but if it's just scratched, this post may help. https://www.hometalk.com/42335424/scratched-leather-repaired-ez
If it's actually torn, I'm not sure there's much you can do, although I believe there are patching products. I don't know how well they work.
What is the damage? A photo would help. Different ways to repair.
