Since organizing my container lids, I've become fond of neater drawers. I bake a lot, and am forever having to forage through a drawer for the correct size measuring cup. They seem the sort of thing that should move out of the drawer and on to the wall, where I can tell exactly which cup I want without having to dig through the drawer. I suppose I could have just hammered some nails in the wall, but a simple black rack seemed a classier solution.
I used standard #6 screws with matching hollow-wall fasteners.
