Salt Dough is an easy to master craft for both children and adults. Adults enjoy making dough crafted objects almost more than children, I believe this is because it reminds them of their childhood days. Kneading Salt Dough at Christmas could become an annual ritual, along with making a gingerbread house.
In fact, you can make all sorts of Salt Dough models including jewellery earrings, necklaces and pendants. Favourites include the Xmas Holly plaque and the holly wreath (easy) or tree ornaments.
