Mount a Magnetic Strip on the Wall
Mount the rack to the wall using screws and a screwdriver.
Place small objects, such as buttons and safety pins, in round metal tins or steel boxes with tight-fitting lids.
Use superglue to affix a sample of the contents to the top of each box so you'll know what's inside; place the bottom side on the magnet.
Suspend larger metal objects, such as scissors or a stainless-steel ruler, directly on magnet.
