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).
Latest DIY project.... Oil drip pan from Walmart $12 + spray paint (use Home Depot vs Michaels waaaay cheaper). And you have your very own magnet board to display kids art work from school, coupons, papers you don't want to forget about or lose. It's literally an oil drip pan for if you were to change your own oil on your car! Don't spend a ton on a huge cookie sheet unless you want that size. This is 47 x 25. Screw into your wall and your all done. Super easy.
