I'm sure someone will correct me if I'm wrong, but I'm pretty sure that "toile" has nothing to do with the weight or fiber content of the fabric. It refers to a printed pattern that is a dark (blue, black, sometimes red) solid color against a white or off-white background and depicts scenes from olden times, often in the European countryside.

If you really liked the feel of the pattern, you can probably find several different weights and designs of toile at a local fabric store. Some might not need to be lined, if the pattern doesn't show through to the back.
