Somebody help me...

Ok... I really think I'm going to go insane. I don't know of anyone else with the same problems I have. But I have those couches that have the big pillows for the back cushions. My kids have this thing where they take down all the pillows and get blankets from anywhere... even if it means taking off the bedspreads and sheets. And I'm totally not kidding. They put them on the floor and pretend they're all kinds of things... from water to cars. I mean I guess its good that their having fun, but I get so mad I can't even tell you how it makes me feel. Then when I tell them to clean it up they just throw it on the bed and couch, then I have to go fix it. I've tried everything from time out to swatting them. But they don't care, they keep doing it. I HATE it! I wish I could make them stop!!! Anyone with a magic wand????
