Crayola model magic is great stuff. It can be shaped into anything and then dried. DD used some to make beads for a necklace. Another idea is to get a box for each child (empty shoe box works) and then have them turn it into a treasure box by decorating it (paint, markers, glitter etc) any way they want. Besides family fun also check out oriental trading company. They have a lot of crafts that you can order as kits or get the supplies at another store.
