Oil Drip Pan Chalkboards! Spray prime the drip pans with gray primer, and then use latex chalkboard paint. Tape a border around the edge of the drip pan so it will create a 'frame' of sorts. Hang the boards/pans using 3M Command Strips (4 medium sized ones did the trick).
Great ideas on various ways to use chalkboard paint. Ideas include organizing by creating a chart on the wall, making cute labels for flower pots, adding easily changeable labels to storage containers, and many more.
