Hey Jeff,
Love the display, thats a cool concept. We're in the process of getting a house, so we'll be moving from our apartment to a nice sized house with plenty of room for more iron, and I've been thinking of this very same idea lately and I'd be curious to see other peoples ideas as well. I have a ton to display and not sure how I'm gonna do it yet. Here's how I currently control my users in my kitchen.
I made it so i can fit two sizes on each shelf. Starting with #0 on top :P and then in descending order 3,4/5,6/7,8/9,10/ and a lid on the bottom.
