Bless your heart! You found it!! I had searched over Facebook and found nothing. It's an interesting process and would be an excellent project for taking with a person. I might be more inclined to "stuff" them by layering with a square of flannel or a flat sort of batting so that it is uniform. Granted, it is certainly a LOT of hand work.
Interesting method and it matches front and back when finished.!
Thanks again for your search.
