Packaging peanuts: Can they be used for crafts?

I found a box full of styrofoam peanuts when cleaning the house today and wondered if they could be used to make Christmas decorations or some other kind of crafts. I think the peanuts are a brilliant material for kids to use in crafts (I know we did when I went to kindergarten) because there’s always so many of them and it’s not really much of a loss if what you’re making doesn’t turn out all that great. I kept improvising all night and came up with a few ideas – nothing too fancy, but definitely worth giving a shot if you’re doing crafts with the little ones. Would you like me to show them to you?
