Before we took our last long vacation, Daisy wanted a way to keep all of her makeup in one place in the trailer without having to fish around in makeup bags or take up counter space:
On the back of each container, a magnet, hot-glued in place. One floating magnet for the tweezers, then two magnet hooks to hold the pencils and applicators in the green basket.
The whole thing held to the wall with four small 3M picture-hanging Command Strips (here).
With all the road vibration in our little trailer, the only problem we had during our two week trip is that the cap for one of the eyeshadow products popped off.
