I think the confusion is that the double fold binding is an object that you use to make a French seam binding on a quilt. I have always heard it called a French seam binding too. It is kinda funny how there is also a French seam that you use to enclose all the raw edges to strengthen the finished garment. But, that has nothing to do with this binding technique.
