Does anyone know if Tempera paint would work well on salt dough ornaments? I just made some with my son and my daycare boy (both one and half years old) and want to paint them with the boys tomorrow. I have a bunch of big old bottles of Tempura. They all say they are non-toxic, but I want to make sure they would work on the salt dough. I also need to go buy a bottle of yellow, but I think I can get one super cheap. This was such a cheap, fun project for the kids!
