The article suggested this: "Cut clutter by telling your kids that anything they don't put away during the week will be placed in the "Saturday Box" - meaning they don't get back a toy left out on Monday until Saturday. (To defeat rescue attempts, she keeps the box in the trunk of her car.) Usually the kids are so eager to hold on to their stuff, they put it away in 15 minutes."
Might be worth a try.
