Of course I picked up this idea on Pinterest.
I already had the printer tray in the garage waiting to be used. I bought two in Frankenmuth over a year ago when I only planned to buy one, but they were half price, therefore the reason for buying two.
I'm glad I did now.
I used a couple of hooks and picture hanging wire on the back to hang it on the wall. To help keep it stationary, I used a command picture hanging hook on each of the two bottom corners.
It's hanging on the half wall outside Caboose's room by the stairs. That way if the little men (or whatever they are) fall off, they won't get lost behind a piece of furniture.
