Design Sponge reader Morgane posted a tutorial for fake drawer hangers (wall hooks) but I think that using real old dresser drawers is cooler and more thrifty. I mean, how many times have you seen dressers sitting on somebody's curb waiting for the trashman!?
If you do it my way, just take a hammer and remove the sides and back of the drawer then add some hanging hardware (picture hangers are available at any hardware store). And if you want, change the nobs and slap (or spray) on a coat of paint.
