The idea is simple really...
Stack your storage items (I used buckets of wheat here, but I've used boxes, bins, just about anything stackable). If you're using a heavy storage item, put some cardboard down to protect the space around it - in this case, the wall, the carpet, and the pretty scrap of wood that's going to sit on top later.
Then just cover it! I used a bed sheet because I didnt have a beautiful table cloth large enough, and I really wanted this scrap wood to show... it already looked like a beautiful table top!
After trimming the cardboard that was sticking out underneath (which should have been trimmed before I finished putting the buckets down), I propped a chair in front of it. A pot of peacock feathers, a few pictures on top, and tada!
This simple idea was a hit at college. Usually the boxes themselves wound up as the table top and the whole thing got a fabric cover. We used similar tables as night stands and sofa backers. Note this: if you're going to put lamps or other heavy items on top, make sure your box, bins, or whatever is strong and heavy enough to handle some good bumping around.
That's a Jannie-Original. Hope it helps you like it did me!
