Gerry,
Also as a reminder, you will glue the leather over the vinyl pieces 11-15, 18-21. Do not remove the vinyl w/padding, factory just glued leather on vinyl w/padding pieces if the SL was ordered with the leather option and also did not matter if the vinyl pieces were of the same color. Also you might want to consider to do 27-30 since you will have a lot of leather left over. For all my pieces, 11-16, 18-25, 27-30 only took 1/2 hide. I had pieces 5-8, and 26 come pre-cut, and not part of the 1/2 of hide, and 9 & 10 were sewn and ready to stretch on door panels. Just remember to cut your pieces as close as you can, that way you are not wasting pieces of the hide. I laid all my pieces out on hide first and penciled my cuts.
Good luck,
Bob
