I hate throwing things away that could be useful (even if I have no current use for them). And there are two things that I hate having to throw out maybe more than any other. One is styrofoam packing peanuts - first of all, it gets all over the place when you try to get it into a garbage bag, but mainly it just seems like such a waste. The other thing that irks my frugal, green side is CDs or DVRs that we've turned into MP3s or just don't need any more.
National Geographic Kids has a great site with lots of educational activities and games for kids. They also have a bunch of kid craft ideas, including directions for making a bean bag chair filled with styrofoam peanuts and a disco ball from old CDs. The perfect solution. You can reuse stuff you don't want to throw away, have a great kid craft activity and end up with some cool items for the kid's room.
I especially like the bean bag chair idea. It's so simple and clever. Just fill a laundry bag with styrofoam peanuts and tighten the draw string. Have your kids personalize their chair by drawing their name and decorating the laundry bag with puffy fabric paint for a little extra fun. (via AT:Nursery)
