Those hard plastic organizers are what I have used, and my categorizing and labeling varies from none to extreme. I'm trying to find storage that takes up less space and is still easy to access, especially when it comes to quickly finding the right screw for the project.
For all of you who thought this thread was about women and partying, you are partially right...It takes a woman to come up with this solution.
Every woman needs a way to keep her jewelry organized, and some of these hanging organizers should work great for my boat. I decided to try one that has no zippers (which would probably get corroded), and it can hang flat in a hanging locker or be rolled for storage (the hanger can be removed). I keep the screws organized by type and size in small zip lock bags, one per pocket, so that I can pull out the bag for the ones that I want to use. I have the zip lock bags labeled so that I can remember what needs to be resupplied. If the zip lock bag gets holes, then the screws are still contained within the heavy plastic pocket. This organizer has 80 pockets of varying sizes, so that should get me started. It's even made with a nautical-looking canvas, not some frilly/girly designed fabric.
For everyone who thought this was a party topic, now you know how to organize your screws. Talk about this new jewelry organizer that you have on your boat, and the women will all want to come aboard to take a look! Just have the Patron/wine/beer chilled... and that's all there is to it!
