To make salt dough, mix a cup of plain flour, 1/2 cup of salt and just under 1/2 cup of warm water in a bowl to firm a dough, add a little more flour or water if your dough seems to sticky or dry.
Roll out the dough on a lightly floured surface and then cut into shapes we used chick, butterflies and egg shapes to go with the Easter/ Spring theme of the tree. Use a straw to make a small hole in each shape and place on a baking tray. Bake in the oven on the lowest setting for around 2 hours until rock hard, i turn mine over halfway through, alternatively leave to air dry(this can take a few days though).
Allow to cool and then paint. We use ordinary childrens paint with no problems, arm yourself with a cup of tea and let the little ones paint away, they don't need to be perfect thats part of the charm, don't forget some wipes to clean them up afterwards! Leave to dry, loop some twine through the holes and hang on your tree.
