Gorilla Tape can stick to leather but may not be the best option for repair. It is best to keep the rip out of reach and not where there is a lot of friction or use. It should work fine. It will likely wear out and leave a sticky residue on leather jackets or sofa cushions. It will also not look as good as leather tape because it will look more like gorilla tape. However, it might be cheaper than leather tape. It might be worth trying something that isn’t subject to a lot of wear and tear and doesn’t need to be visually pleasing.
