Minibus Seat Repair?

[PhoenixBob]

At present I am driving a 15 plate seventeen seat Ford Transit minibus and the seats are upholstered in a black nylon type fabric. The problem I have is some moron has burnt the rear of one of the seats with what I suspect to be a cigarette lighter. This has resulted in a hole approximately 10/12 mm high and 5/8 mm wide. Does anyone know or recommend a kit I can get to patch the hole. I'm not looking for an invisible repair here, just something that's decent because I know that if I leave it as it is other cretins will keep worrying the hole until the whole back of the seat is completely ruined. If there's anyone out there that can help me I would be very grateful.

Bob.
