I've Become The Glue Nazi

Last year, I wrote about my upside down glue.  I love it and am never going back! Upside down glue is the way to go! 
I am way over the slime craze.  I can't even deal. I had several glue bottles taken last year (I'm sure to make slime), and I'm over it.  I wanted an organizational system so I could--at a glance--see what was missing.  I decided to paint my glue bottles to match my tables:

This summer, I did some research and experiments and found that if I sanded the glue bottles with 150 grit sandpaper, then taped and painted them, I could use my E6000 glue to add the magnets.

Painters tape applied at exactly the same spot on each bottle.

 

Pushed into an old foam cushion.

I left them outside for an hour or so to fully dry.

Peeling the tape off.

Here they are hanging (I added color signs in rainbow order):

 I won't say it's perfect, here's how it looked after kindergarten the other day:

But it's so easy to snap back into place, and it's a system I'm loving.
