One of the things that eats up A LOT of storage space is the sealed plastic containers and boxes I keep most of my things in. Here in the Phoenix desert there is dust EVERYWHERE constantly building up over and over again. I also like to seal up things as much as I can for fear of cockroaches and other insects getting into my stuff. The big disadvantage about how my stuff is “organized” is that it’s scattered, in containers and boxes and therefore it’s often a PAIN to find something I know that I have. And of course, I also forget what I have already because I can’t find it LOL!
