This is the way I was storing my bakeware in a lower cabinet. This is not a terrible arrangement, but not accessible either. I was spending my time standing on my head or down on my knees searching for the pan I needed.
I kept thinking of how to make my sheet pans and such stand up, so I bought two of these corner shelves.
I turned them sideways and pushed them to the back of the cabinet shelf.
Then I just slid all the sheet pans, muffin pans, and other bakeware into the slots, and it worked.
I am really happy with this new bakeware arrangement. I can see my pans now, and I don't have to stand on my head or crawl around the floor to find the one I want.
