I also have a blog for these dolls The World of Pourlieduns.
I've made 6 so far including Isabelle above. They've all been adopted and are happy to travel to their new homes!
This is how I make them. Just air dry natural clay. I put them on the foil paper so they don't stick while the dry. Then a couple coats of a buttery paint color for the skin. Next I paint the details and 2 coats of varnish seals everything.
Some scraps of fabric and a crown finish these little shabby chic princess dolls.
