just thought i would share. many of the kids play dough sets have plastic molds which can be used to 3d fondant figures and cake decorations. just let the kids play with the play dough and keep the molds for your cake decorations. you can find them with the play dough and some of the great molds come with the moon sand. all are plastic and washable, like the play dough, give the moon sand to the kids to play with.
