I am having fun making my own molds for stucco and decorating different things with it. The material for flexible molds, I´ve used is called Siligum and is very easy to work with. There is a lot of videos on Utube showing how. I use self drying clay in the molds for the stucco. The pictures show a lion, I made this way for a collection of mirrors with patinated wooden frames. You can find wholesize pictures of the different mirrors on Petit Brocante.
