We've tried lots of different things to hold the kids toys. Laundry baskets. Shelf made from old drawers. And the most recent attempt, an old bakers rack that was left in our shed by the former owner we were using for tools.
After wiping it down I used my favorite kind of paint for furniture {or just about anything}: Spray Paint. After getting the entire thing coated with the blue, I used some cardboard and tape to block off the wooden top and sprayed it with black chalkboard paint then added simple white knobs I had in my pile of "leftover" parts from projects.
I pulled it up on the deck and added toys. We'll see how long this lasts and if it makes the kids wanna put their things away any more than the other tries.
