There are a couple of things about the KonMari method of storage that I'm finding work incredibly well - so well that I can't understand why I never thought of doing them before.
One is store things vertically so you can see everything. For example, I had a banker's box in which I kept our extra oral care supplies - toothbrushes, toothpaste, floss, etc. Everything just got tossed into the box, and it worked okay, in that we always knew where to find a new toothbrush or tube of toothpaste, and I always knew where to put new items when I brought them home from the store. But in tidying the box, I found myself discarding lots of samples and old kids' toothbrushes that are too small for the kids now. And I wanted to be able to really see what's in there at a glance. I hit upon the idea of storing everything standing up in zip-top plastic bags, like so:
We had a similar arrangement with razors and Q-tips, which I kept in a different banker's box. Everything was a jumble, but I was able to use more zip-top bags to group the men's razors, the disposable razors, and the women's razors together:
Which brings me to another wonderful aspect of the KonMari method of storage: keep like things together. For example, I had jewelry in two different locations. I tended to only look in one location, so when I sorted through my jewelry, I realized I had many pieces I hadn't worn in a long time simply because I'd forgotten all about them. I kept only those pieces that sparked joy, and then rearranged my storage so that everything is in one spot, and easy to see from above. And now every time I go to get my wedding ring, I put on another piece of jewelry (or two or more) that make me happy.
