Here is an Ebay listing for cotton fabric. It has Model T's all over it.

I have a good amount of this in my stash but somebody might need some. I made mine into a quilt and have our cars embroidered on it.
Order some, it's a thoughtful give if your significant other quilts or sews. It is almost that season of shopping and give give give!
