I don't know if I'm too late, but was that whiteboard you turned into two bulletin boards magnetic? If so, you could use magnets instead of tape that would ruin your lovely paper when taking things down.
Great video! For teacher toolbox, have you checked out Home Depot, Menards, Lowes, not sure if you also have ACE or Harbor Frieght where you live. They're pretty much plastic tool organizer. Just thought I'd share. Wishing you a wonderful school year!
