I have 20 tall cubbies with the square compartment at the top. They have no hooks whatsoever...so what can I do keep the area looking neat? I am trying to avoid buying 3M hooks because they get expensive...I wouldn't count on Dollar Tree Hooks because they wouldn't hold up. Maybe I could get 3M hooks for cheap in bulk, but I don't now where. Any suggestions? I know this is a tricky one.
