We have used the above technique and it really works! (Click the caption to read about it). The other thing we do that is really successful, is to use a pillowcase or black garbage bag called Mr. Grabby, and each day he grabs all the kids stuff that is lying on the floor of their rooms, (toys, books, clothes). And to get each thing back, they have to do a job. On family night we take it out and dump out the things and the kids determine what they want back. If they don't want it back, it goes to goodwill. This is a fabulous way to end clutter in your kids rooms!
