NEAT TRICK: This one’s for all you incoming freshmen. To put it bluntly, locker avalanches are social kryptonite. There is nothing worse for one’s reputation among new and potential friends than a deluge of books, papers, pens and half-eaten sandwiches in the middle of the hallway. Take a step in the right direction with a couple of handy-dandy Locker Shelves from The Container Store. Foldable, stackable and sturdy, they’re a lifesaver when it comes to squeezing all your necessary school supplies into a seriously cramped space. Those icky sandwiches, on the other hand, you’ll have to tackle on your own. GET IT: Silver Mesh Locker Shelves, $9.99 each. Available online and at area Container Store locations.
