I'm almost embarrassed to post this. It was too easy.
I have two bathrooms and no drawers in either of them. The only storage available is the medicine cabinets. There are closets, though, fitted with shelves, outside each bathroom.
If you wanted an extra tube of toothpaste you could look in the medicine cabinet, or in the closets. I never knew where to find it or even whether we had any. It was ridiculous. When I created my Household Goods Inventory Checklist, I realised, again, that I needed to create just one place to look.
So, I did. First, though, I had to put this pile back on the basement shelves.
Then, I could find my little plastic "shoeboxes" hidden at the back. I ran around the house gathering up all the extra toothbrushes, floss, and toothpaste. Then, I labelled it and placed it on a shelf in the pantry.
Now I need to organize the pantry! (Again.)
