Shelves. Specifically something like these. You piece it together yourself so you can make them as tall/short/wide/narrow as you want to work around furniture already in your home. Everything is organized enough that I can find it it but still open and visual. And if you do want it not as visible or it's a bunch of small things, you can use cube organizers.
