With regards carpeting.... Just the same as you. Cockpit first and boot second. I'll be attempting to use either tiff paper or thin card to make the templates.
I finished off the bonnet surround and bonnet at the weekend. I wound up lining the inner of the bonnet with heat resistant cloth, not because I thought it needed it but more because it looked crap (thanks Mr painter). Actually came out quite well. If you look closely at the pic you'll notice that the red on the inside of the bonnet does not match the colour of the car. That's what happens when you don't use lacquer...
Cheers...
