A while back I stumbled across this rather brilliant way of storing tubes of paint. http://njainschigg.blogspot.com/2011/12/paint-storage.html
I've always stored my paints in buckets, tackle boxes, cardboard boxes, etc. It always results in the tubes getting really beat up, covered in other paint, covered in oil, and just an overall mess. Not a great system.
But this system Nicholas came up with seemed like it was just the solution for me, so I built one. I still need to put some screws in the wall and hang it up, but for now it's doing great. I used "cup hooks" rather than nails/screws.
I've still got a ton of other tubes of paint. I'll have to make a couple more of these...
