Is it the closet away from home, or just a metal container where you stash books?
Either way, why not upgrade your locker and decorate it?
Magnets, mirrors and stickers are standard (just make sure the stickers are removable). But poster paper can be put to good use too — as wallpaper or even to cut out shapes. Get creative.
Cover your locker with post-it notes for friends to write little notes on, or just write them yourself. You are the one looking at it every day, after all. What do you prefer to open the door to? Whether it is a two-foot-tall poster of your favourite (shirtless) movie star, a cardboard seascape, or just all black wallpaper, it’s up to you.
