Ok, not the actual cereal, the box. My kids eat a lot of cheerios, so I buy the giant boxes that never fit on the shelf correctly. Rather than struggling with the giant box several times a day (cereal is not a breakfast only food if you are 1 and a half), I decant, leaving me with a cereal box in pristine condition. Typically this box would immediately be broken down and sent to recycling, but in the throws of organizing, this box looked suspiciously like a magazine file box.
Mark a 45 degree angle on a large cereal box. The high side of the angle should end in one of the top corners of the box before the flaps begin (if the high side is at the top right on the front, it will be on the top left in the back).Cut along the mark you made. Be careful cut the box cleanly.This is what the box should look like after it has been cut.Wrap the box in heavy weight paper. I used craft paper, which requires strong tape.Then shove some magazines in it. Ta Da! The box really can't stand up to the weight of the magazines on it's own, but it does a great job when propped against something heavy, like other magazine boxes.
