Strouty,
I know well, what it's like to have a plan that doesn't look right to others.
To most of us, your stock room looks more than fine.
But in your mind, it is far from that. Plus it is something you MUST do.
Do note though, that perfectionism is a symptom of hoarding.
What I am finding, in my organizational tasks, is that it is more important that things find a final resting place, than exactly where that place is. There is a tendency, in the hoarder/perfectionist, to keep improving things, and moving things around. You never know where the latest location is. You never get in the habit of going there for the item.
I CAN understand that you do want to find that final resting place for every item, so you can start memorizing where things are.
And you have completed all the large projects that weather allowed. Now is the time to do all the finer sorting and organizing. But give yourself a "good enough" goal.
It's funny, but when I saw your binding supplies, it reminded me that I have that same binder and supplies for it. I lived over it in the office for years. I even used it to make a few binders. Then I realized that I didn't use it much. It is now out in a shed, and may never be used again. I should probably get rid of it. I don't have a need to make binders. I use PDF files. In fact, I used to print out manuals for everything and put them in 3 ring binders. I had a whole cabinet full of them. I finally tossed them all out. I realized that I had never referenced them, and they were all PDF files on my computer and phone anyway. That is something you might do. Make a run through all the things in the supply area and pick up each item and ask yourself if you can do without it. Keep an empty box next to you as you do this, and quickly toss the item as soon as you make the determination. And at the end of the session, quickly dispose of the box full of stuff.
I have 3 buckets full of those grey Carlon outside boxes. Went through them and realized they were almost all sizes and configurations I would never need. It is surprising how much stuff was acquired blindly, that I have no real use for. Once I look at it and REALLY determine it's true value (Or lack of value) to me, I can easily determine it's fate.
