Looking outside the norm to find the right tools

A few years ago, a friend, whose wife is also an artist, shared with me that she was using these metal trays as her palettes, so that she could cover them, in between with saran wrap to keep the paints moist. She works in acrylic, while I work in oils. While my palettes don't dry out as quickly since I work in Oil, they still do dry out. I've been looking for something to use to hold the linseed oil I work with, turp etc in containers that I'm working with that can be closed up so the liquids don't vaporate as quickly...as well as finding something to hold my palettes so they also can be covered. Today I found them, in bed bath and beyond. A couple of cookie sheets, and spice containers with tops and magnetized bottoms are perfect.
