Step 6: Peeeeeeel!
You might find that you have some places where the paint comes off. I know I did! This is normal when you paint metal. :P If you'd like to fix the spots, spray some spray paint into a small container (I've used the cap of the spray paint with great success) and paint it on using a tiny brush.
I did not fix mine because I was feeling good about them, small paintless spots and all!
Enjoy your new and extremely cheap storage containers! Mine gave me enough room to get all my sewing accessories out of the way. :D
