I'm sorry Alan I can't supply a link to the material. I paid a visit to a fabric shop in Blackpool and found the fabric by chance. I'm not sure what its purpose is. You could be right, I thought it looks like the material that lines waterproof clothing. Funny you should ask about the business though. Someone saw my effort and asked if I could make another. It's not really practical though, as I would have to make it in situ. PM sent
