The alligator grain vinyl I put on my headliner board was really thick but it layed out perfect with no wrinkles. I honestly did not think it was going to work. Wal-Mart sells various types of vinyl too. I got my sail panel board vinyl from there and the headliner vinyl from Jo-Annes fabrics.
Gosh you really got me thinking about that foax leather stuff! Would look so cool, I guess I'll see how well this foam backed fabric does since I already spent the money.....
